Defeasance versus yield maintenance in multifamily debt

Defeasance and yield maintenance can both support the release of financed real estate, but they do so through different transactions. Yield maintenance accompanies repayment of the loan. Defeasance substitutes permitted collateral supporting the continuing debt, commonly with a successor borrower. The owner should compare the complete cost and closing process for the route actually available under the documents.

Chatham Financial explains this distinction in its yield-maintenance discussion.^[1] A borrower cannot select whichever route looks cheaper merely because both exist in the market. The agreement determines whether either is available, the earliest date, the payment schedule and any exceptions.

Establish the permitted exit before calculating a premium

Read the note, security instrument, prepayment provisions and defeasance section together. Record lockout dates, required notice, permitted payment dates, the open-prepayment window and restrictions on partial transactions. Identify whether the trigger for an available route depends on origination, securitization or another event.

For REMIC-qualified defeasance, 26 CFR §1.860G-2(a)(8)(ii) includes conditions concerning permitted government securities, original loan terms and a two-year period measured from the REMIC startup day.^[2] That is different from assuming two years after the loan was funded. The borrower must also satisfy its contract, which may impose separate conditions.

Obtain the relevant startup information and a written eligibility confirmation before committing to a sale timetable. If companion loan interests are involved, determine whether another securitization's conditions matter. The ICNQ 2024-MF agreement expressly addresses companion REMIC timing in its defeasance provisions.^[3] This illustrates a coordination issue; it does not establish the dates for another owner's loan.

Understand what yield maintenance measures

Yield maintenance generally compares remaining contractual debt payments with a specified reinvestment or discount benchmark to calculate a prepayment amount. The coupon, remaining term, amortization, benchmark selection and contractual formula all matter. Minimum premiums and payment-date rules may affect the final amount even when a simplified present-value model produces a low result.

Chatham's explanation uses discounted remaining payments and cautions that its calculator is an estimate that does not incorporate every loan's specific provisions.^[1] The owner's model should therefore reproduce the actual contract and reconcile to an authorized payoff calculation. A generic online result is useful for sensitivity analysis, not a binding statement of funds required to release the mortgage.

Consider a simplified hypothetical $80 million interest-only loan with five annual payments remaining and a 7.00 percent coupon. Assume an invented yield-maintenance formula equal to the present value of five $5.6 million interest payments and the $80 million balloon, minus $80 million. Assume annual compounding, no minimum premium, no accrued interest and no other fees.

At an assumed 4.00 percent discount rate, the remaining payments have a present value of approximately $90.684 million. The illustrative premium is $10.684 million. At 6.00 percent, their present value is approximately $83.370 million and the premium is $3.370 million. These are original simplified scenarios, not loan quotes or a claim that actual contracts use annual payments.

The sensitivity explains why an exit estimate can move materially even when the outstanding principal has not changed. The $7.314 million difference between those scenarios should be considered alongside any expected benefit from selling or refinancing. The analysis needs the exit date and contractual calculation, not simply an assertion that the loan's rate is above or below today's rate.

Understand what the defeasance budget buys

Defeasance funds a portfolio of eligible securities generating the required payment cash flows. The budget typically includes collateral acquisition and the parties and documents needed to establish the replacement arrangement. Chatham describes a successor borrower, a securities intermediary and an accountant's cash-flow certification.^[4] Whether every component is required, who selects providers and what the owner retains depend on the documents.

A portfolio price can differ from a theoretical present value because actual eligible securities must match payment dates and amounts. Their prices, availability, settlement and permitted types matter. Do not treat one benchmark yield as an executable quote for the entire portfolio. Also identify whether the collateral supports payments through maturity or through an earlier permitted payoff date.

The ICNQ agreement illustrates document requirements for eligible securities, a perfected-security-interest opinion, a cash-flow certificate and REMIC-related legal review.^[3] It is one securitization's execution process. A borrower should request its own servicer's checklist and allocate responsibility for every deliverable rather than assume that purchasing bonds completes the transaction.

Compare total release funding on the same date

Suppose the owner's hypothetical alternatives are a yield-maintenance payoff of $90.684 million plus $75,000 of assumed administrative and legal costs, or a defeasance portfolio costing $90.2 million plus $300,000 of assumed transaction costs. The comparison is $90.759 million versus $90.5 million, a $259,000 difference. These invented quotes illustrate comparison mechanics only; no actual transaction is described.

The portfolio price already represents the replacement funding. Do not add the $80 million principal again to the defeasance budget. Conversely, do not compare a yield-maintenance premium alone with a defeasance portfolio's full price. Both sides must measure the total amount needed to obtain the relevant property release, with accrued payments and other charges treated consistently.

If defeasance is the only contractual route, the cheaper hypothetical payoff is unavailable. If a future open window allows payment without a premium, waiting introduces additional operating, sale-price and financing risks. Compare the complete alternatives that can actually close, including how carrying the asset until a later date changes cash flows.

Clarify residual value and continuing obligations

Chatham describes possible residual value from timing differences and a permitted early payoff of a defeased loan.^[4] The owner should identify who receives it, whether it has been assigned or monetized and whether the estimate is guaranteed. A theoretical residual should not reduce the closing cash budget unless the applicable transaction actually supplies that cash.

Review the original borrower's and guarantor's releases expressly. Mortgage collateral can be released while particular obligations survive under indemnities or other agreements. The successor-borrower documents and release instruments should specify the scope, rather than relying on a general description of defeasance as debt extinguishment.

The tax regulation permits a qualifying collateral substitution under stated conditions; it does not itself grant a borrower contractual release or erase surviving liabilities.^[2] Treat tax eligibility, mortgage release, borrower substitution and guarantor release as separate closing questions.

Prepare a coordinated closing budget

Obtain eligibility confirmation, an initial estimate, a fee schedule and a funds-flow draft before an exit becomes urgent. Mark which prices remain variable and when they become binding. Coordinate purchase or refinance proceeds with bond settlement or loan payoff, and ensure notice and signature requirements fit the transaction calendar.

Chatham notes that defeasance estimates vary with bond prices and that the payment horizon follows the loan documents.^[4] Recalculate the budget as the closing date moves. A useful comparison shows permitted route, total release funding, remaining price exposure, document responsibility and continuing obligations. Those facts give the owner a practical basis for deciding whether to execute now, renegotiate the sale or wait.
