The Complete Guide to Commercial Real Estate Prepayment Penalties: Defeasance, Yield Maintenance, and Step Down Structures

How Step Down penalties, Yield Maintenance, and CMBS Defeasance actually work, and how to underwrite the exit before you sign the acquisition loan.

September 8, 20265 min readBy Price Capital Group

In commercial real estate, institutional debt is what allows an owner to maximize acquisition leverage. Newer investors, though, often ignore the exit mechanics inside their loan documents until the day they decide to sell or refinance. That oversight can be expensive. When a commercial mortgage is signed, the lender may be relying on contractual interest income across a defined period, and paying the loan off early can trigger a prepayment premium designed to recover that foregone yield.

For legacy landlords, syndicators, and private equity sponsors, the legal and mathematical mechanics of a payoff matter as much as the going in cap rate. Miscalculating a prepayment penalty can absorb a meaningful share of the equity in a deal and turn a profitable liquidation into a disappointing one.

Here is how the three primary structures work, how lockout periods and open windows govern timing, and how to align debt with your business plan. Prepayment provisions vary by loan documents, so treat everything below as an educational framework rather than a description of your specific loan.

Step Down Prepayment Penalties

The Step Down prepayment penalty is one of the most straightforward structures, and it is common in some regional bank and credit union loans. It sets a percentage penalty against the outstanding loan balance that decreases, or steps down, each year the loan stays in place.

As an illustrative example, a five year commercial loan may use a 5 4 3 2 1 structure:

Year 1: Five percent of the outstanding balance.
Year 2: Four percent.
Year 3: Three percent.
Year 4: Two percent.
Year 5: One percent.

That schedule is an example only. Actual step down percentages, terms, and triggers depend on the signed loan documents.

The Underwriting Reality

If you sell an industrial warehouse in year two with a remaining balance of two million dollars, a four percent penalty would cost eighty thousand dollars out of the sale proceeds. Step Down penalties are highly predictable, which is their main advantage, but they weigh heavily on short term value add strategies. A sponsor planning a rapid repositioning and a twelve month exit should price that penalty into the underwriting before signing, not after the buyer is at the table.

Yield Maintenance

Yield Maintenance is a mathematically involved premium used frequently by life insurance company lenders and Agency lenders such as Fannie Mae and Freddie Mac. Those institutions often package loan yield into bonds sold to investors, so their documents are written to compensate for foregone contractual yield when a loan is repaid ahead of schedule.

Under a typical yield maintenance clause, an early payoff requires the outstanding principal balance plus an amount intended to make the lender whole on the interest it will no longer receive. The premium is generally computed by comparing the contract rate on the loan against the current yield of a Treasury security of a corresponding maturity, then discounting the difference to present value.

Yield Maintenance Penalty = Present Value of Lost Interest

Yield maintenance formulas vary. The exact index, discount rate, and calculation convention are defined in the loan documents, and two loans that both say yield maintenance can produce very different numbers.

The Interest Rate Risk

Yield maintenance is sensitive to macroeconomic rate movement. If you locked a low rate and later sell into an environment where comparable Treasury yields have fallen, the lender's foregone yield is larger and the premium can be substantial. If Treasury yields have risen well above your contract rate, the calculation often falls back to a minimum premium, frequently expressed as a small percentage of the outstanding balance. Minimum premiums vary by loan, so confirm the floor in your documents rather than assuming a standard one percent.

Rate exposure is one of several reasons debt terms deserve the same scrutiny as the asset. Our commercial real estate debt financing guide and capital stack guide cover how those layers interact.

Defeasance: The CMBS Collateral Substitution

Commercial Mortgage Backed Securities loans are among the most rigid debt vehicles in commercial real estate. Many CMBS conduit loans restrict voluntary prepayment outright and instead require a process known as defeasance in order to sell or refinance the encumbered property. Industry groups such as CREFC publish standards and reporting conventions across conduit debt and commercial mortgage securitization.

Defeasance is generally a collateral substitution structure rather than an ordinary prepayment. In broad terms, the sequence works like this:

The property is being sold or refinanced, which triggers the loan documents' payoff provisions.
The borrower arranges substitute collateral through a defeasance consultant and legal counsel.
Government securities or other permitted securities are acquired according to the loan documents.
The substitute collateral is structured so its scheduled payments support the remaining debt service on the loan.
The real estate collateral can then be released if the contractual defeasance conditions are satisfied.

Permitted substitute collateral depends on the loan documents. Government securities are common, but the specific eligibility rules, the successor borrower structure, and the servicing requirements vary by CMBS transaction. No two defeasance closings should be assumed to follow identical mechanics.

The Execution Friction

Defeasance is administratively heavy. It typically requires a defeasance consultant, an accountant, legal counsel, a rating agency or servicer review, and a successor borrower entity. Execution costs vary materially by transaction and sit entirely apart from the cost of the substitute securities themselves. As Jason highlights in Why Most Businesses Fail Before They Even Start, weak operating systems are where capital gets destroyed. Attempting a defeasance without a disciplined transaction timeline puts the sale escrow at risk.

The Lockout Period and the Open Window

When underwriting institutional debt, two timeline parameters can override every penalty calculation in the documents.

The Absolute Lockout

Many institutional loans, particularly CMBS and Agency debt, include a lockout period early in the term during which voluntary prepayment is prohibited or restricted. While a lockout is in place, the property generally cannot be sold or refinanced free and clear regardless of how much the borrower is willing to pay. Lockout periods vary, so read the term in your own documents rather than assuming a standard length.

The Open Window

Many loan structures also include an open window near maturity, a defined period during which repayment may be permitted without the earlier prepayment premium. Open windows vary by loan structure in both length and conditions. Where one exists, institutional allocators frequently time their liquidation so the closing lands inside it, which removes the premium from the payoff math entirely.

Operational Discipline: Matching Debt to Your Business Plan

Debt is a tool, and it needs to match the hold period the business plan actually calls for. In Private Money Lending: 3 Deals, 3 Answers, we walked through how short term private bridge loans can offer flexibility, letting a sponsor exit without a heavy yield maintenance premium. Our guide to private money lending in commercial real estate covers where that capital fits.

On highly stable assets, such as the single tenant pad analyzed in Would You Lend 800K on This Burger King Deal, long term fixed rate debt can make sense, because the sponsor intends to hold for a long horizon and early payoff friction is less relevant.

The principle behind The Discipline Loop: Why Your Process Beats Your Goals applies directly here: calculate the exit penalty before signing the acquisition loan documents, not during escrow. And as shown in What Is a Cap Rate? Running the Numbers on Three Fort Myers Warehouses, the sale cap rate has to generate enough proceeds to clear the debt and any payoff premium while still delivering the return metrics the equity was underwritten to.

Bypassing Escrow Delays with Direct Corporate Liquidation

Managing a defeasance timeline or a yield maintenance calculation while depending on a traditional financed buyer introduces real timing exposure. If that buyer requests a thirty day escrow extension because their loan is delayed, the closing can slip past the open window and reintroduce a premium that had already been engineered out of the deal.

A direct off market sale to an established corporate cash buyer can reduce that timing uncertainty. Direct acquisition groups use discretionary capital, which can support a more defined closing timeline aligned to the loan's open window. In some cases a buyer may also assume existing debt, though assumption depends on lender or servicer consent and the terms of the loan, and an assumption may alter or avoid some prepayment consequences depending on the documents. Confirming the payoff path early, alongside standard due diligence, keeps the exit predictable.
