AEO Quick Answer / September 2026 Finance and Owner Advisory Reference
Commercial construction finance combines a 3-tier capital stack - senior debt at 60-75% loan-to-cost, mezzanine debt or preferred equity for the gap, and sponsor + LP equity for the balance - funded through a construction loan that converts to permanent at stabilization. The owner job is to underwrite to a yield-on-cost that exceeds the exit cap rate by a healthy spread.
Successful commercial development clears two financial tests: (1) the project pencils on yield-on-cost vs exit cap rate spread (typically 150-250 basis points); and (2) stabilized DSCR clears the takeout lender threshold (commonly 1.20x-1.30x). Gauge financing readiness in minutes with the free construction loan qualifier and anchor total project cost with the TCG.ai estimator. TCG owner representative, preconstruction, and equipment procurement services protect the underwriting from pre-development through closeout. A&E and soft costs typically run 15-30% of total project cost - the line owners most often underbudget. As of September 2026, the Fed has raised the federal funds target to 3.75-4.00 percent, the 10-year Treasury sits near 4.94 percent, and construction input prices are up 8.9 percent year over year, so size interest reserves and contingency to a stress case, not the base case.
New rate, escalation, bonus depreciation, Section 179D, and Opportunity Zone updates for 2026 underwriting. See the September 2026 capital markets snapshot below, plus the September refreshes of the cost, building systems, and delivery pillars. Most recent guide refreshes:
The playbook below still holds. What moved is the cost of money, the cost of the building, and the tax tools that offset both. Four changes to put into every 2026 pro forma before you approach a lender. Run the numbers with the construction loan qualifier and the TCG.ai estimator.
Rates moved up, not down
On September 16, 2026, the Fed raised the federal funds target 25 basis points to 3.75-4.00 percent, citing persistent energy and consumer price pressure. As of September 17, the 10-year Treasury was 4.94 percent and bank prime 7.00 percent (Federal Reserve H.15).
SOFR-based construction loans reprice with the policy rate. Size interest reserves at +100bp and re-test takeout DSCR. C2P conversion.
Hard costs are escalating
Construction input prices were up 8.9 percent year over year in August 2026 (ABC). Steel mill products were up 22.5 percent and aluminum 40.5 percent through July (AGC), with Section 232 tariffs now on full customs value. Carry 5 to 9 percent escalation on metal and MEP-heavy scopes and fund contingency to match. Contingency by project type / September 2026 cost benchmarks.
Tax tools: bonus up, 179D closing
OBBBA permanently restored 100 percent bonus depreciation for qualifying property acquired after January 19, 2025, which makes cost segregation more valuable. Section 179D ended for projects that begin construction after June 30, 2026; projects already under physical construction by then can still qualify. Qualified production property adds a temporary 100 percent deduction for certain manufacturing buildings. Confirm with tax counsel.
Opportunity Zones 2.0
OBBBA made Opportunity Zones permanent. Governors began nominating a new, stricter tract map on July 1, 2026, effective January 1, 2027, with rolling 5-year deferral and a 10 percent basis step-up (30 percent for rural funds). Gains deferred under the original program must be recognized by December 31, 2026. Site selection for 2027 starts should check the new map. Adaptive reuse.
Section 1 / Capital Stack
The Capital Stack - How Commercial Projects Get Funded
Every commercial development is funded through a layered capital stack. Senior construction debt sits at the bottom (lowest cost, lowest risk, first claim on cash flow). Common equity sits at the top (highest cost, highest risk, last paid). Mezzanine debt and preferred equity fill the gap. Knowing how the stack is built and what each layer costs is the foundation of commercial real estate underwriting. SBA 504 loan guide covers owner-occupied capital stack mechanics; the free construction loan qualifier gives a first read on where your project sits.
Sponsor / GP EquityHighest risk / Highest return / Last paid
Developer / sponsor capital. Carries promote / waterfall returns above LP threshold. Targets 18-30%+ IRR depending on asset class and risk profile.
3 to 15%
LP / Common EquityPari passu with GP after preferred returns
Limited partner capital from family offices, syndicators, or institutional investors. Typically receives a preferred return (8-10%) before promote splits with GP.
Subordinate to senior debt but senior to common equity. Provides flexibility - does not require senior lender consent. Common on $10M-$50M deals.
5 to 15%
Mezzanine Debt10-15% all-in / Pledge of equity interests
Debt secured by pledge of property-owning entity equity (not real estate lien). Sits between senior debt and equity. Standard structure for filling LTC gap above senior leverage.
5 to 15%
Senior Construction DebtSOFR + 250-500bp / 60-75% LTC
Bank or non-bank construction lender. First lien on the property. Funded in monthly draws against approved schedule of values. Converts to mini-perm or permanent at stabilization.
60 to 75%
Senior Debt
Bank Construction Loan
SOFR + 250-450bp / 60-75% LTC
Traditional bank construction loan. Lower cost, more conservative LTC, more recourse, more covenants. Best fit for experienced sponsors with banking relationships and strong asset classes - build-to-suit industrial, credit tenant, owner-occupied. Pairs with GMP delivery.
Private debt funds and bridge lenders. Higher cost, higher leverage, faster execution, fewer covenants, more flexibility. Standard on speculative, opportunistic, value-add, and complex transitional product. The dominant capital source on cannabis, complex cold storage, and certain data center deals.
SBA 504 loan combining a senior bank loan (50% LTC) with an SBA-guaranteed CDC second (40% LTC) and 10% borrower equity. Owner-occupied commercial only. SBA 504 commercial construction loan guide covers eligibility, structure, and typical use cases. Check fit with the loan qualifier.
Debt secured by pledge of equity interests in property-owning entity. Stretches total leverage to 80-90% of cost. Requires senior lender intercreditor agreement. Generally lower cost than preferred equity but less flexible. Standard on mid-market commercial.
Structured as equity but receives preferred return before common equity. Does not require senior lender consent. More flexible than mezz on workout. Higher cost than mezz on like-for-like leverage. Common on opportunistic, ground-up, and complex value-add product.
Limited partner capital from family offices, accredited syndications, institutional LPs. Typically receives preferred return (8-10%) before promote splits with sponsor. Standard waterfall: 8% pref to LP, 80/20 split through 12% IRR, 70/30 above. Driven by sponsor track record.
Sponsor capital. Carries promote / waterfall above LP threshold. Targets 18-30%+ IRR depending on asset class. Sponsor co-invest signals alignment to LPs and lenders. On lender-required co-invest, typical floor is 10% of total cost held by GP and approved sponsor team.
Construction Loans, Draws, and the Pay Application Process
A construction loan funds in monthly draws against documented work in place. The mechanics - schedule of values, pay applications, lien waivers, project monitor reports, retainage - are where projects either run cleanly or where draws delay, sub payment slows, and schedule erodes. How to read a commercial GC bid covers the structures referenced below. Loan draw schedule deep-dive. Construction-to-perm conversion.
Loan Closing
Loan-to-Cost (LTC) Sizing
60-75% LTC standard
Senior loan amount = LTC % times total project cost (TPC). TPC includes hard costs, soft costs, interest carry / interest reserve, leasing/lease-up costs, developer fee, and contingency. Higher LTC for build-to-suit and credit-tenant; lower for speculative product. Balance funded by equity, mezz, or preferred. Gauge your position with the loan qualifier.
Line-by-line breakdown of contract value by cost code (CSI MasterFormat). Becomes the basis for monthly pay applications, percent-complete tracking, and retainage calculation. Lender approves SOV at loan closing. Front-loaded SOVs are a draw red flag - the project monitor is paid to catch them.
Monthly application from GC certifying percent-complete by line item, less retainage, less prior payments. Requires unconditional lien waiver from GC (and major subs) on prior payment, conditional waiver on current. Submitted to project monitor, owner, and lender. Standard funding cycle: 30-45 days from work to draw funding.
Conditional waiver = signed; valid only when payment clears. Unconditional waiver = absolute waiver of lien rights. Standard practice: GC and all subs above $5K-$10K provide both with each draw. Title insurance date-down endorsement at each draw confirms no intervening liens. Lien waiver types guide / Mechanics lien timing by state.
Independent third party retained by lender. Reviews plans/budget at loan closing, verifies work in place at each draw, evaluates change orders, reports schedule and budget risk. Owners should treat the monitor as a partner - the monitor catches problems early on the lender behalf, which protects equity too.
Interest during construction (IDC) is a soft cost - capitalized into the loan via an interest reserve. Sized at loan closing based on draw curve and projected SOFR. Reserve running out before substantial completion is a leading cause of mid-project capital stress. Monitor IDC vs budget monthly. After the September 16, 2026 Fed hike to 3.75-4.00 percent, size reserves to a +100bp stress case.
Owner withholds 5-10% of each draw until completion. Many states allow reduction at substantial completion (50% reduction or full release with bond). Retainage held by owner is also withheld by GC from subs. Cash flow impact for subs is real - tight retainage management is part of being a fair owner. Retainage release mechanics.
Performance and payment bonds protect the owner against GC default and subcontractor non-payment. Required on most projects above $1M and on all public projects. Bond capacity reflects GC financial strength. Surety bonding for commercial GC covers capacity, rates, and lender coordination.
Mini-perm: 3-7 year fixed-rate loan that takes out the construction loan at substantial completion before stabilization. Perm: 10+ year permanent mortgage executed once asset reaches stabilized DSCR (typically 1.20x-1.30x). Mini-perm bridges the lease-up gap on speculative product.
Single loan that funds construction at variable rate, converts to fixed permanent at substantial completion. Eliminates refinance risk and second closing. Standard on owner-occupied, build-to-suit, and credit-tenant industrial properties. C2P conversion deep-dive.
The Owner Pro Forma - NOI, Yield, and the Spread Test
A development pro forma boils down to one question: does projected stabilized NOI divided by total project cost (yield-on-cost) exceed the prevailing exit cap rate by a healthy spread? If yes, the project is creating value. If no, the deal is not pencilling. Every other underwriting metric - IRR, equity multiple, DSCR - is downstream of this single test. Industrial NOI strategy walks through how envelope decisions move stabilized NOI.
Pro Forma Top Line
Net Operating Income (NOI)
Effective gross income minus opex
Gross potential rent minus vacancy/credit loss + other income = effective gross income (EGI). EGI minus operating expenses (taxes, insurance, utilities, maintenance, management, R&M) = NOI. Stabilized NOI is the basis for cap rate valuation, yield-on-cost calculation, and DSCR. Envelope and NOI strategy.
The development yield. 2026 typical ranges: industrial / warehouse 7-9%; multifamily 5.5-7%; self-storage 6-8%; cold storage 8-11%; data center 8-11%; healthcare / lab 6-8%; QSR / outparcel 8-10%. The owner job is to underwrite to a yield that exceeds prevailing exit cap rates by 150-250 basis points. Anchor the denominator with the TCG.ai estimator.
Yield-on-cost minus exit cap rate equals the developer value-creation margin. The single most important feasibility filter. When cap rates rise, spreads compress, deals stop pencilling. When cap rates compress, spreads widen, more deals pencil. Interest rate environment drives the spread. With the 10-year Treasury near 4.94 percent in September 2026, test the spread against flat-to-higher exit cap rates.
Internal Rate of Return (IRR) measures time-weighted return on equity. Equity Multiple measures total cash returned per dollar invested. Industrial development targets 15-22% IRR with 1.7x-2.2x equity multiple over 4-7 year hold; opportunistic targets 22-30%+ IRR. Used by LPs to compare deals across asset classes.
Stabilized NOI divided by annual debt service. Permanent lenders require 1.20x-1.30x minimum at takeout (1.40x-1.50x for hospitality, cannabis, speculative). Construction lenders require pro forma DSCR projection at takeout. Run sensitivities at -10% rents and +100bp rates - deals that fail this stress test are vulnerable.
The period from substantial completion to stabilized occupancy. Industrial 6-12 mo. Multifamily 12-18 mo. Office 18-36 mo. Retail 9-18 mo. Cold storage 6-12 mo (typically build-to-suit or pre-lease). Lease-up assumptions and TI/LC budgets drive equity returns more than any other line item on most projects.
Run base, downside, and stress cases on every deal. Standard sensitivities: rents -5%, -10%, -15%; cap rate +25bp, +50bp, +100bp; construction cost +5%, +10%; lease-up -3 months, -6 months. Deals that do not pencil at base -10% rents and +50bp cap should not be funded.
FF&E and specialty equipment runs 5-15% of TPC on most commercial; 15-25%+ on cold storage, cannabis, healthcare, lab, data center, QSR. TCG direct manufacturer procurement saves 15-35% on these line items through volume relationships.
Tax Incentives, Cost Segregation, and Capital Efficiency Tools
Federal and state tax incentives can move project economics by 5-20% on the right deals. The tools owners use most: cost segregation, bonus depreciation, Section 179D, Section 48 ITC, Opportunity Zones, NMTC, Historic Rehabilitation Tax Credits, and 1031 exchanges. Tax law has shifted materially in the last several years - current applicable rates and rules should always be confirmed with tax counsel for the placed-in-service year.
Important: Confirm Current Rules with Tax Counsel
Tax incentive rates, eligibility, and phaseouts have changed multiple times in recent years through major legislation. Specific deduction percentages, eligibility thresholds, and Opportunity Zone rules referenced below are subject to change. Owners and developers should confirm current applicable rules with qualified tax counsel and engineering-based cost segregation specialists before relying on any specific number for underwriting.
Cost Seg + Bonus Dep
Cost Segregation Studies
An engineering-based study reclassifies portions of building basis from 39-year commercial property into shorter recovery periods (5, 7, 15-year). For a $20M building, typical reclassification of 15-30% of basis generates $1M-$3M in present-value tax savings. Pairs with bonus depreciation. Most impactful on industrial, cold storage, manufacturing, healthcare, hospitality, and data center. Direct procurement documentation supports the study.
Accelerated Dep
Bonus Depreciation
First-year deduction of qualifying property with a recovery period of 20 years or less. Under OBBBA, 100 percent bonus depreciation is permanently restored for qualifying property acquired and placed in service after January 19, 2025 (acquisition generally keyed to the binding contract date). Pairs with cost seg: cost seg identifies the 5, 7, and 15-year property; bonus depreciation deducts it in year one. OBBBA also added a temporary 100 percent deduction for qualified production property (certain manufacturing buildings, construction beginning after January 19, 2025 and before 2029). Confirm eligibility with tax counsel.
Energy Efficiency
Section 179D Deduction
Federal deduction for energy-efficient commercial building property - envelope, HVAC, lighting that exceeds ASHRAE standards. OBBBA terminated 179D for property whose construction begins after June 30, 2026. Projects that began physical construction on or before that date can still qualify when placed in service later, at about $0.59 to $1.19/SF base or up to about $5.94/SF with prevailing wage and apprenticeship. Still relevant for in-progress IMP-envelope cold storage, FM-rated assemblies, and high-performance industrial started before the cutoff. Document the begin-construction date.
Solar / ITC
Section 48 Investment Tax Credit (ITC)
Federal tax credit for qualifying renewable energy property - solar PV, solar thermal, energy storage, geothermal, fuel cell. Credit value depends on property type and prevailing wage / apprenticeship / domestic content adders. Direct-pay and transferability provisions allow tax-exempt entities and developers without tax appetite to monetize the credit. Often pairs with ENERGY STAR targeting.
Capital Gain Deferral
Opportunity Zones
Federally designated low-income census tracts where investors can defer and reduce capital gains tax via reinvestment into a Qualified Opportunity Fund. Three benefits: deferral of original gain; potential basis step-up; elimination of QOF appreciation tax if held 10+ years. OBBBA made the program permanent: a new, stricter tract map takes effect January 1, 2027, with rolling 5-year deferral and a 10 percent basis step-up (30 percent for rural funds). Gains deferred under the original program must be recognized by December 31, 2026. OZ-eligible commercial includes industrial, multifamily, mixed-use, healthcare. Consult counsel.
Community Development
New Markets Tax Credit (NMTC)
Federal credit for investment in qualifying low-income community businesses and real estate. Allocated through Community Development Entities (CDEs). Standard structure delivers 4-7% net subsidy on eligible projects via leveraged loan structure. Highly impactful on health centers, community-serving retail, mixed-use development, and adaptive reuse in qualifying census tracts. Administered by CDFI Fund.
Adaptive Reuse
Historic Rehabilitation Tax Credit
20% federal credit for certified rehabilitation of certified historic structures. Many states stack additional 10-25% state HTC. Highly impactful on adaptive reuse, mixed-use loft conversion, and downtown infill projects. Requires National Park Service approval. TCG adaptive reuse.
Capital Recycling
1031 Like-Kind Exchange
Allows deferral of capital gains tax when proceeds from sale of investment real estate are reinvested into qualifying like-kind property within statutory deadlines (45 days to identify, 180 days to close). Standard tool for capital recycling across investment property. Requires qualified intermediary and strict adherence to identification and exchange rules.
Section 5 / Owner Advisory Team
9 Advisory Roles That Protect the Owner Equity
Beyond the GC, architect, and lender, sophisticated owners assemble a parallel advisory team that protects equity returns through every project phase. Some roles are required by lender policy, others are owner-elected. The right team configuration varies by project size, asset class, and complexity. TCG owner representative service coordinates the team on the owner behalf.
External developer hired on fee basis. Runs site selection, entitlement, design coordination, construction oversight, lease-up. Used by capital partners without internal development capability.
Construction Lender Rep
Lender Side
In-house or external lender representative. Reviews draws, manages loan administration, monitors covenant compliance. Different from project monitor - lender rep is internal to lender team.
Project Monitor / IFA
Independent Verification
Independent third-party inspector retained by lender. Verifies work in place, reviews change orders, reports schedule and budget risk. Owner pays as soft cost.
Cost Seg Specialist
Tax Engineering
Engineering-based firm performing cost segregation studies. Identifies property qualifying for accelerated recovery. Coordinates with CPA on filing. AICPA guidelines apply.
Negotiates GC contract, sub agreements, owner-architect agreement. Reviews lien waivers, change orders, claims. Manages disputes. State-licensed; specialty in construction law.
Tax Counsel / CPA
Tax Strategy
Tax structure, entity selection (LLC, partnership, REIT), 179D allocation, NMTC, OZ structuring, 1031 exchange coordination. Critical at structuring - not after the fact.
Capital Markets Advisor
Debt and Equity Placement
Mortgage broker / investment bank placing senior debt, mezz, and equity. Compensated on placement fee or retainer. Critical on $20M+ deals or complex capital structures.
Section 6 / Financial Decision Frameworks
Five Financial Decisions Every Owner Faces
Five recurring financial decisions shape the economics of every commercial project. The TCG verdict on each - based on a decade of project work across 38 states and over a million square feet of IMP installation.
Build-to-Suit vs Speculative - Which development structure?
Build-to-Suit (BTS)
Pre-leased to credit tenant before construction. Lower lender LTC requirements (often 70-80%). No lease-up risk. Lower returns (cap rate spread compressed). Standard on industrial, QSR, healthcare, fleet depot.
Speculative (Spec)
Built without pre-lease commitment. Lender LTC tighter (55-65%). Higher returns potential, lease-up risk concentrated. Standard on multifamily, self-storage, small-bay industrial.
TCG verdict: BTS for first-time developers, capital-light sponsors, and tight markets. Spec for experienced developers with deep market knowledge, sufficient equity, and diversified pipelines. The wrong call - speculative product without lease-up capital reserve in a softening market - is the leading cause of mid-project capital stress.
Owner-Occupied vs Investor (Sale-Leaseback) - Which capital structure?
Owner-Occupied
Operating company owns and uses the building. Captures appreciation, tax depreciation, and rent expense substitution. Capital tied up in real estate. Standard on credit-strong corporates and family-owned operating businesses.
Sale-Leaseback / Investor
Operating company sells building to investor and leases back long-term. Frees capital for operations / growth. Higher rent expense. Investor captures appreciation. Standard on PE-backed operating companies, REIT-eligible assets.
TCG verdict: Owner-occupied for credit-strong corporates with low cost of capital and long property hold horizon. Sale-leaseback for capital-constrained operators where freed capital can earn above the implied rent yield. The decision is fundamentally about cost of capital relative to cap rate - if your cost of capital exceeds the prevailing cap rate, the building should be sold and leased back. Owner-occupied builders should start with the SBA 504 guide and the loan qualifier.
Construction-to-Perm vs Construction Loan + Separate Permanent Takeout?
Construction-to-Perm (C2P)
Single loan, single closing, locks rate at construction loan closing. Eliminates refinance risk. Limited optionality at takeout. Best on owner-occupied, BTS, and credit-tenant industrial.
Separate Construction + Takeout
Two closings. Borrower shops permanent market at takeout. Maximum flexibility on permanent terms. Refinance risk if market moves. Standard on speculative product, value-add, and complex transitional product.
TCG verdict: C2P if rates are favorable at construction loan closing and the owner expects to hold long-term. Separate construction + takeout if the owner expects rates to fall, the market is volatile, or the project has multiple potential takeout options. On most $5M-$30M speculative deals, separate construction + takeout is the default. In September 2026, with the Fed tightening and the 10-year Treasury near 5 percent, rate-lock certainty through C2P deserves a fresh look on long-hold owner-occupied product. C2P conversion guide / FRED rate data.
Mezzanine Debt vs Preferred Equity for the Capital Stack Gap?
Mezzanine Debt
Debt secured by equity pledge. Lower cost (10-15% all-in). Requires senior lender intercreditor consent. More restrictive covenants. Standard on stabilized and lower-risk product.
Preferred Equity
Structured as equity. Higher cost (9-13%+ pref). No senior lender consent required. More flexible on workout. Standard on opportunistic, ground-up, and complex value-add.
TCG verdict: Mezz when senior lender will sign a workable intercreditor and the project has stabilized cash flow. Preferred equity when senior lender will not allow mezz, when the project has higher execution risk, or when the sponsor wants more flexibility on workout. Mezz is generally cheaper; preferred is generally more flexible.
Spend on High-Performance Envelope vs Standard - What is the NOI math?
High-Performance Envelope
IMP envelope, high R-value, tight air-sealing, FM 4880-rated where insurance requires. Higher first cost. Lower opex (utilities, maintenance, insurance). Higher NOI. Eligible for 179D, ENERGY STAR. Better tenant retention.
Standard Envelope
Tilt-up, conventional CMU, or basic insulated metal. Lower first cost. Higher opex. Lower NOI capture per dollar of basis. Not eligible for premium energy incentives.
TCG verdict: High-performance envelope wins on cold storage, food processing, cannabis, data center, and any industrial product where opex matters. Envelope efficiency and NOI strategy walks through the math: a 15-25% opex reduction at a 7% cap rate translates to 200-350bp of value uplift - the envelope premium pays for itself many times over. FM-rated panels also reduce property insurance premiums by 10-30%. Spec the envelope with the Building Systems pillar.
Underwrite the Deal / Then Build It Right
The biggest gains in commercial development come from underwriting the deal correctly - capital stack, yield-on-cost, exit cap spread, lease-up risk, contingency. Once that is right, build it through a single-source design-build team that protects the underwriting from pre-development through stabilization. Schedule a 30-minute call to walk through your project.
Common Questions About Commercial Construction Finance and Owner Advisory
What is a commercial construction loan and how does it work?v
A commercial construction loan is short-term debt (typically 12-36 months) that funds construction in monthly draws against documented work in place. The lender disburses against an approved schedule of values, with each draw verified by a project monitor. Interest is paid monthly on the outstanding balance (commonly via interest reserve). At completion the loan converts to mini-perm or pays off through permanent takeout. Standard structures: senior debt 60-75% of total cost, balance funded by sponsor equity, mezz, or preferred equity. Gauge financing readiness with the free construction loan qualifier. TCG owner rep manages the draw process. Draw schedule deep-dive.
What is the typical loan-to-cost (LTC) for a commercial construction loan?v
LTC typically runs 60-75% on commercial construction loans in 2026. Industrial, build-to-suit, and credit-tenant: often 70-75%. Speculative office, hospitality, cannabis: 55-65%. Balance funded by sponsor equity, LP equity, mezz, or preferred equity. LTC differs from LTV (loan-to-value) - LTV applies to stabilized appraised value at takeout, often allowing higher leverage at refinance. MBA publishes industry benchmarks.
What is yield-on-cost and how do I calculate it?v
Stabilized NOI / Total Project Cost. 2026 typical: industrial 7-9%, multifamily 5.5-7%, cold storage / data center 8-11%, healthcare 6-8%, QSR / outparcel 8-10%. Spread between yield-on-cost and exit cap rate is the developer value-creation margin - 150-250 basis points typical on viable deals. Compress the spread and the deal stops working. NOI strategy / anchor total cost with the TCG.ai estimator.
What is the difference between hard costs and soft costs?v
Hard costs = physical construction (site work, foundation, structure, envelope, MEP, finishes, FF&E) - typically 70-85% of TPC. Soft costs = non-construction (A&E 8-12%, legal, financing/interest carry, permits/impact fees, taxes, insurance, surveys/environmental, marketing, owner rep) - 15-30% of TPC. Full A&E and soft cost breakdown.
What is a cost segregation study and how much can it save?v
An engineering-based study reclassifies portions of building basis from 39-year (commercial real property) into 5/7/15-year recovery periods. For a $20M building, typical reclassification of 15-30% of basis generates $1M-$3M in present-value tax savings depending on owner marginal rate, time horizon, and current bonus depreciation rules. Study cost $5K-$25K. ROI generally 10x-50x the study fee on $5M+ projects.
What is bonus depreciation and how does it apply to commercial real estate?v
Under the One Big Beautiful Bill Act (OBBBA), 100 percent bonus depreciation is permanently restored for qualifying property with a recovery period of 20 years or less that is acquired and placed in service after January 19, 2025 (acquisition generally keyed to the binding written contract date). Property under binding contract before January 20, 2025 stays on the prior phase-down schedule. Pairs with cost segregation: cost seg identifies the 5, 7, and 15-year property; bonus depreciation deducts it in year one. OBBBA also added a temporary 100 percent deduction for qualified production property (certain nonresidential buildings used in manufacturing and production, construction beginning after January 19, 2025 and before 2029). Confirm eligibility with tax counsel.
What is Section 179D and who qualifies?v
Section 179D is a federal deduction for energy-efficient commercial building property (envelope, HVAC, lighting) that beats ASHRAE 90.1 baselines. OBBBA terminated 179D for property whose construction begins after June 30, 2026. Projects that began physical construction on or before that date can still qualify when placed in service later. For 2026, the deduction runs about $0.59 to $1.19/SF at the base rate and up to about $5.94/SF with prevailing wage and apprenticeship. For tax-exempt owners, the deduction can be allocated to the designer. Confirm the begin-construction date and documentation with tax counsel. IMP-envelope cold storage.
What is an Opportunity Zone investment and how does it benefit commercial development?v
Opportunity Zones are federally designated low-income census tracts where investors can defer and reduce capital gains tax by reinvesting gains into a Qualified Opportunity Fund (QOF). Three benefits: deferral of original gain; potential basis step-up; elimination of QOF appreciation tax if held 10+ years. OBBBA made the program permanent: governors began nominating a new, stricter tract map on July 1, 2026, effective January 1, 2027, with rolling 5-year deferral and a 10 percent basis step-up (30 percent for qualified rural funds). Gains deferred under the original program must be recognized by December 31, 2026. OZ-eligible commercial includes industrial, multifamily, mixed-use, healthcare. Consult counsel for current rules.
What is mezzanine debt versus preferred equity?v
Mezzanine debt: secured by pledge of equity interests; structured as debt with defined coupon and maturity; typical pricing 10-15%. Preferred equity: structured as equity; receives preferred return ahead of common; typical pricing 9-13% with optional kickers. Mezz generally lower cost; preferred more flexible because no senior lender consent required. Most $10M-$50M deals stack senior + mezz + sponsor or senior + preferred + sponsor.
What is the role of an owner representative in financing?v
The owner representative is the owner advocate - distinct from GC, architect, lender. Validates draw schedules, reviews pay applications and lien waivers, monitors budget vs SOV, manages change order review, coordinates with project monitor, oversees commissioning and closeout, protects owner contingency. On $5M+ projects, typically pays for itself many times over by catching draw discrepancies and incomplete close-out. TCG owner rep.
What is a draw schedule on a construction loan?v
The timing/amount mechanism by which the lender disburses loan proceeds. GC submits monthly pay application showing percent-complete by line item against the schedule of values. Project monitor verifies; lien waivers collected; lender funds. Standard cycle 30-60 days from work to draw funding. Owners track three metrics: budget burn vs percent complete (early-loaded SOVs are a red flag), retainage held, stored materials documentation. Full draw schedule guide.
What is a project monitor or inspecting architect on a construction loan?v
Independent third party retained by lender to monitor on its behalf - verifying work in place, reviewing pay apps, evaluating change orders, reporting risk. Monitor performs full plan and cost review at loan closing and conducts site visits at each draw. Fees typically 0.05-0.25% of loan amount; paid by borrower as soft cost. Owners should treat the monitor as a partner; the monitor catches problems on the lender behalf, which protects equity too.
What is DSCR and what is required for commercial financing?v
Debt Service Coverage Ratio = stabilized NOI / annual debt service. Most commercial permanent loans require minimum DSCR of 1.20x-1.30x; some asset classes (hospitality, cannabis, speculative) require 1.40x-1.50x. Construction-to-perm requires borrower demonstrate project will achieve minimum stabilized DSCR (often 1.25x) at takeout. Run sensitivities at -10% rents and +100bp rates - deals failing the stress test are vulnerable.
What is the cap rate spread to construction yield, and why does it matter?v
Spread = Yield-on-Cost minus Exit Cap Rate. 150-250 basis points typical on viable ground-up development. The spread is the developer value-creation margin. When cap rates compress (rates fall, asset values rise) spreads widen. When cap rates expand (rates rise) spreads compress and deals stop pencilling. The spread test is the single most important feasibility filter on commercial development. CBRE cap rate research.
What is a construction-to-permanent loan?v
A single loan that funds construction at a short-term variable rate, then converts to a permanent fixed-rate mortgage at substantial completion or stabilization - eliminating second closing and refinance risk. Available primarily on owner-occupied, build-to-suit, and credit-tenant industrial. Investor multifamily and speculative product more commonly use construction loan + separate permanent takeout. C2P closes faster and locks rate but limits refinance optionality. Full C2P guide.
What pre-development costs should I budget for a commercial project?v
Pre-development (incurred before construction loan closing) typically includes: land acquisition / earnest money; site due diligence (Phase I, geotech, ALTA survey, title); A&E fees through SD or DD; market study and appraisal; legal and financing fees; permit application and impact fees; preliminary marketing; pre-opening opex for owner-operators. Total 3-7% of TPC. Most lenders require this equity in place before construction loan closing. Underbudgeting pre-development is a leading cause of capital stack failure.

How do September 2026 interest rates affect commercial construction financing?v
On September 16, 2026, the Federal Reserve raised the federal funds target range 25 basis points to 3.75-4.00 percent, citing persistent energy and consumer price pressure. As of September 17, 2026, the 10-year Treasury was 4.94 percent and the bank prime rate 7.00 percent (Federal Reserve H.15). SOFR-based construction loans reprice with the policy rate, so size the interest reserve at a +100 basis point stress case, re-run takeout DSCR at current permanent rates, and test the yield-on-cost to exit cap spread against a 10-year Treasury near 5 percent. Construction loan qualifier / C2P conversion.
How should construction cost escalation be handled in a 2026 loan budget?v
Construction input prices were up 8.9 percent year over year in August 2026 (ABC analysis of BLS PPI data), led by aluminum, steel, copper, and diesel. Lenders and project monitors expect budgets priced earlier in 2026 to carry 5 to 9 percent escalation on metal and MEP-heavy scopes, plus a contract escalation clause and early long-lead buyout. Under-budgeted escalation is now one of the fastest ways to exhaust owner contingency and trigger an equity re-balance call. Contingency by project type / escalation clauses in the delivery pillar.
The Complete Series
The Four Pillars of Commercial Construction
TCG pillar library is built around the four questions every commercial real estate developer, owner, and operator asks before a project breaks ground: what will it cost, what systems should I specify, how do I run the project, and how do I fund and underwrite it. Each pillar is a self-contained reference; together they form the complete owner playbook.
Every article and service page on terrapincg.com, organized by topic cluster. Each article cross-links to this finance pillar and to the other three pillars; together the library forms the complete reference for commercial real estate developers and owners.
