Debt & capital markets
Office Debt Structuring
Use this page to compare actual office financing terms and cash-flow scenarios. Office Debt Markets 2026 owns dated market evidence; lender selection, tenant income, rollover, required capital and sponsor liquidity determine which proposed structure can execute. The review of October 14 removes unsupported generic 2026 pricing, leverage and covenant ranges. The examples below are assumed calculations, not available terms or investment conclusions. Set investor objectives, price, hold period, liquidity needs, risk tolerance and the work plan before comparing structures.
Also known as: Office Capital Stack, Office Financing Stack

Commercial Bank vs. Life Co. vs. CMBS: Office Comparison
Compare dated offers and governing documents rather than assigning a standard office loan to each lender label:
| Dimension | Evidence to obtain for each bank, LifeCo or CMBS offer |
|---|---|
| Proceeds | Actual advance, valuation basis and applicable LTV, debt-yield and DSCR sizing; do not assume one channel provides more proceeds. Use the shared closing-cash bridge for funded allocations and usable loan cash. |
| Rate and term | Named index/tenor or fixed coupon, spread, floor, reset dates, fees, maturity and permitted extensions. |
| IO and amortization | Exact payment schedule, IO end date, amortization term and balloon balance. |
| Prepayment | Actual lockout, permitted repayment dates, notice and contractual premium, yield-maintenance or defeasance provisions. |
| Recourse | Executed guarantees, carve-outs, caps, burn-offs and enforcement conditions; a channel label does not establish recourse. |
| Changes and workouts | Decision-maker, required consents, servicing documents and limits on modification/extension authority. Do not assume a bank will modify or that a securitized loan cannot be modified. |
| Execution constraints | Collateral, tenant and sponsor conditions, closing requirements, lender portfolio limits and approval process. |
There is no verified universal 2026 LTV, spread, tenor, IO premium or closing timeline in this comparison. A concentration screen is not evidence of a legal lending cap or of a specific lender's available proceeds. Compare terms under the same property cash flow, capital plan and hold period. Build that cash flow through Office Underwriting and Lease Structures. Use CRE Capital Stack and Debt Structuring for the common sizing framework.
Interest-Only Periods: Office Impact
Hypothetical schedule: $60M principal, 6% nominal annual interest, a three-year term, and no fees, curtailments or irregular periods. The amortizing case uses equal monthly payments at period end over 360 months; the IO case pays interest only throughout the three years.
| Measure | Full-term IO | Immediate 30-year amortization |
|---|---|---|
| Scheduled annual debt service | $3,600,000 | $4,316,763.78 |
| Balance after 36 scheduled monthly payments | $60,000,000 | $57,650,442.06 |
| Current cash effect, with other cash flows unchanged | More cash remains after scheduled service | Less cash remains after service; scheduled payments reduce principal |
The amortizing annual constant is about 7.194606%, above the 6% coupon. See Source: CRE Loan Math Reproduction 2026 for payment assumptions and CRE Capital Stack and Debt Structuring. The inherited balance range lacked a maturity date; it is replaced with the explicit 36-payment comparison.
IO alone does not create income, asset appreciation or a refinance commitment. Test maturity balance against actual takeout terms, income, value, liquidity and required capital. Review whether reserve funding, distributions, amortization transitions or voluntary paydowns change the cash/equity bridge. This example establishes neither a 2026 office value decline nor the prevalence or pricing of IO by lender. A failed refinance test does not establish that a paydown and default are the only possible outcomes.
Interest Rate Hedging for Office Floating-Rate Debt
Determine the hedge requirement from the proposed loan and hedge documents. This page does not establish a universal office hedge mandate or current premium.
| Hedge input | Required scope |
|---|---|
| Loan exposure | Index, tenor, spread, floor, reset/payment dates, principal schedule and basis mismatch. |
| Rate cap | Executable dated quote, strike, notional, expiry, premium, settlement terms and counterparty requirements. |
| Coverage | Keep contractual loan debt service and accessible hedge receipts separate; apply the lender's actual cash-flow, hedge and payment tests. Include fees, amortization and capital cash needs. |
| Extension | Required replacement/extension of the hedge, its price and permitted counterparties; no automatic renewal assumption. |
| Swap or collar | Matched cash flows, premium or financing cost, collateral requirements and termination/settlement exposure. |
Use CRE Capital Stack and Debt Structuring for the conditional index-strike, margin and receipt calculation. Its matched example separates gross loan interest from hedge cash; expiry at fixed loan inputs removes the receipt. A different index, smaller notional, loan floor or later settlement can change cost or due-date liquidity. Verify actual terms before treating a strike as a ceiling on combined cash, and do not use it as an all-in loan coupon. Source: Chatham Cap Payout Methods 2026 supports the written-method distinction; Distressed Asset Underwriting owns the expiry review.
Interest Rate Swaps (longer-term floating loans): Swaps convert floating to synthetic fixed. Illustrative arithmetic: SOFR + 275 bps floating loan; 3-year swap replacing SOFR at 4.10% fixed gives 6.85% before other fees, floors or basis differences (4.10% + 2.75%). The assumed quote is not a verified current-market swap rate. Unlike caps, swaps have mark-to-market termination risk if rates fall.
The swap illustration assumes matching index, notional and payment terms; verify those inputs before treating the arithmetic as actual financing cost. See Source: Debt Benchmark Conventions Review 2026 for index/benchmark distinctions. Treasury yields are not swap quotes or office debt coupons.
Assumed collar: A purchased 5% cap and sold 3% floor can limit the modeled index's upside and downside exposure under their actual terms. Price both legs and test the floor obligation; do not infer that the collar is free, that premiums fully offset, or that these strikes are lender-approved or available quotes.
Mezzanine and Preferred Equity in Office
When senior proceeds leave a capitalization gap, evaluate subordinate debt or preferred equity against the actual cash flow, documents and investor terms:
| Dimension | Mezzanine Debt | Preferred Equity |
|---|---|---|
| Legal Form | Loan to an ownership entity secured by identified pledged equity interests | Equity investment with negotiated priority distribution/control rights |
| Pricing Inputs | Dated coupon, fees, accrual, proceeds and repayment terms | Dated current/deferred return, fees, participation and exit terms |
| Foreclosure Remedy | Applicable Article 9 remedies on pledged interests; timing and conveyed rights require document/legal review | Contractual control, sale or other remedies only where granted and permitted; no automatic transfer |
| Senior Lender Interaction | Check senior/program permissions and any required ICA, cure, standstill and enforcement conditions | Check origination and control-transfer approvals; equity status does not bypass senior restrictions |
| Tax Treatment | Review debt classification and applicable deduction limits | Review equity classification and applicable tax treatment |
| When to Use for Office | Proposed debt/collateral structure is permitted and fits proceeds, cash flow and recovery needs | Priority economics and ownership rights fit the capitalization need and are permitted by senior documents |
The table was reviewed October 7, 2026 for structure and document diligence; it does not establish current pricing or a tax deduction. See Preferred Equity and Mezzanine Mechanics and Source: Preferred Equity and Mezzanine Primary Review 2026. The Fannie multifamily program example demonstrates conditional equity review and takeover approval; its specific rules are not transferred to office/CMBS loans. For the common rights-to-execution review, use Preferred Equity and Mezzanine Mechanics. Establish the actual right holder, approval stage, cash needed and completed act rather than assigning consent, timing or recovery from the instrument label.
Illustrative Capital Stack - $100M Office Acquisition (assumed terms, not market quotes):
| Layer | Amount | Share of price | Assumed economics | Position to verify |
|---|---|---|---|---|
| Senior debt | $60M | 60% | 6% coupon; IO in the cash example | First lien and actual loan terms |
| Mezzanine debt | $15M | 15% | 12% current pay; IO in the cash example | Pledged ownership interests and permitted remedies |
| GP / sponsor equity | $5M | 5% | Stated 20%+ target IRR, not an achieved return | Actual common-equity allocation and promote terms |
| LP equity | $20M | 20% | Assumed 8% preferred return and promote split | Actual distribution priority, accrual and loss allocation |
Total debt is $75M, or 75% of price; common equity falls from $40M to $25M. That reduction alone does not establish higher cash yield or IRR. Separately assume annual NOI $8M, no additional initial/annual cash uses, unchanged price and senior terms, and all cash after service available to common equity. Senior-only annual service is $3.6M: common-equity cash is $4.4M / $40M = 11%. Added mezzanine service is $1.8M: cash is $2.6M / $25M = 10.4%. Blended current debt service is 7.2% of debt, below the 8% NOI cap, yet adding mezzanine lowers current cash yield versus the senior-only case.
The marginal financing test is in Cap Rate Decomposition. Full-return comparison requires dated operating cash flows, capital needs, fees, principal repayment, refinance and exit assumptions. Aggregate common-equity cash yield does not determine either GP or LP return; apply Equity Waterfall and Promote Structures to the actual agreement. Use Office Equity Waterfall and Promote Structures to trace actual financing cash, capital contributions, allocation terms and payment authority before reporting partner outcomes. Replacing debt with preferred equity requires its actual payment/control terms, not an automatic debt-coupon substitution.
Loan Covenants: Office-Specific Triggers
Build a covenant schedule from the actual documents. The prior generic office thresholds are not verified lender/program minima or default rules.
| Test | Record and stress |
|---|---|
| DSCR | Defined income/cash flow, included debt payments, measurement period, required ratio, cure and remedies. |
| Debt yield | Defined income, debt denominator, test dates and consequences; it is not interchangeable with DSCR. |
| Occupancy and tenant triggers | Physical/economic occupancy basis, specified tenant events, materiality, cure period and permitted response. |
| Capital and leasing reserves | Required funding, release conditions, permitted uses, upcoming TI/LC and actual capital plan. |
| Extensions | Each condition, test date, income assumptions, hedge, fees, paydown, consent and liquidity needed before maturity. |
| Cash management and default | Distinguish a reserve/sweep trigger, failed extension condition, covenant breach and payment default under the documents. |
See Source: Debt Yield Scope Review 2026 and Source: CRE Loan Math Reproduction 2026 for scoped income/debt-service definitions. Program-specific definitions do not establish universal office minima. Do not assume that failure triggers immediate acceleration or that modification is available. Model the available paths and their permissions, costs and funding needs; use Distressed Asset Underwriting for the broader recovery analysis.
Negative Leverage: Current Cash Test
Use Cap Rate Decomposition for the matched annual cash calculation. Coupon, annual debt-service constant, effective financing cost and total-return IRR are different measures.
Separate hypothetical IO case: Price $100M, annual NOI $6M, debt $60M at 7% IO and equity $40M; assume no other costs or cash uses. Annual service is $4.2M and equity cash yield is $1.8M / $40M = 4.5%, versus the unlevered 6%. This is negative current cash-yield leverage under the stated assumptions; it does not establish total-return IRR or the share of office acquisitions with negative leverage.
Amortization counterexample: With a 7% NOI cap and debt equal to 60% of price, the separately assumed 6% coupon / 30-year monthly schedule above gives a 7.194606% annual constant and about 6.708091% equity cash yield. Cap above coupon therefore does not ensure positive current cash leverage. Actual capital/lease cash uses can reduce cash further. Rate declines, NOI growth or future refinancing are scenarios to stress, not established remedies or investor conclusions.
