What Is Defeasance?
Defeasance is a provision in commercial real estate lending that allows borrowers to release their property from a mortgage lien by substituting a portfolio of U.S. Treasury securities for the original collateral. Rather than simply prepaying the loan, the borrower purchases government bonds whose cash flows exactly match the remaining scheduled payments on the loan. The CMBS trust continues to receive its expected payments, the borrower gets their property back, and both parties are satisfied.
Defeasance is most commonly associated with CMBS (Commercial MortgageBacked Securities) loans, where the loan has been securitized and sold to investors. Because investors purchased bonds backed by the mortgage payments, the servicer cannot simply accept an early payoff – the cash flow stream must be maintained. Defeasance solves this by replacing the property collateral with risk-free government securities.
How Is Defeasance Cost Calculated?
The cost of defeasance has several components:
Treasury Bond Portfolio Cost – The largest component. A portfolio of U.S. Treasury securities (bills, notes, and bonds) is assembled so that their coupon payments and maturities exactly match each remaining scheduled payment on the loan. When market interest rates are lower than your loan’s interest rate, treasuries trade at a premium, making defeasance more expensive. When rates are higher, defeasance becomes cheaper.
Transaction Fees – Typically $50,000-$75,000 in total, including: defeasance consultant/advisor fee, legal counsel for borrower and servicer, accountant verification, successor borrower fee, servicer processing fee, and rating agency fee (if applicable).
Interest Shortfall – If your defeasance closes mid-month, you may owe interest for the period between your last payment and the substitution date.
Defeasance vs Yield Maintenance
Both defeasance and yield maintenance are prepayment provisions in commercial real estate loans, but they work in fundamentally different ways:
Yield Maintenance
Defeasance
Which costs more?
It depends on the interest rate environment. In a rising rate environment (rates above your loan rate), defeasance tends to be cheaper because treasuries are discounted. In a falling rate environment, both methods become expensive, but yield maintenance is often the cheaper option because defeasance requires purchasing premium-priced bonds.

FAQs
What is defeasance?
Defeasance is a process that allows a commercial real estate borrower to prepay a loan secured by a CMBS (Commercial Mortgage-Backed Securities) trust without actually paying off the debt early. Instead of returning cash to the trust, the borrower substitutes a portfolio of U.S. Treasury securities that replicates the remaining loan payment schedule. The trust continues receiving the same cash flows, and the borrower's property is released from the mortgage lien.
How is defeasance cost calculated?
Defeasance cost is calculated by determining the price of a portfolio of U.S. Treasury securities whose cash flows exactly match the remaining scheduled loan payments (principal and interest) through maturity. The total defeasance cost includes the price of the Treasury portfolio plus transaction fees such as legal costs, accounting fees, successor borrower fees, and servicer processing fees. When interest rates are lower than the loan rate, defeasance becomes more expensive because Treasury securities are priced at a premium.
What is the difference between defeasance and yield maintenance?
Both defeasance and yield maintenance are prepayment mechanisms for commercial loans, but they work differently. Yield maintenance requires the borrower to pay a lump-sum penalty equal to the present value of the remaining interest payments the lender would have received, minus what they can earn by reinvesting at current Treasury rates. Defeasance requires substituting a Treasury bond portfolio. Defeasance is typically required for securitized (CMBS) loans, while yield maintenance is more common in portfolio or balance-sheet loans. In a rising rate environment, defeasance can be cheaper; in a falling rate environment, both become more expensive.
What is a defeasance clause in real estate?
A defeasance clause in a commercial real estate loan agreement is a provision that specifies whether and how a borrower may substitute collateral (typically U.S. Treasury securities) for the mortgaged property in order to release the lien. It outlines the conditions under which defeasance is permitted, including lockout periods, required notice, eligible replacement securities, and the process for transferring obligations to a successor borrower.
How long does defeasance take?
A typical defeasance transaction takes 30 to 45 days from start to closing. The timeline includes engaging a defeasance consultant, obtaining a payoff statement from the servicer, purchasing the replacement Treasury securities, completing legal review, and closing. Some transactions can be expedited to 2–3 weeks if all parties are responsive and the loan documents are straightforward.
When does defeasance make sense?
Defeasance makes sense when you need to sell or refinance a property with a CMBS loan that includes a defeasance clause, especially when the property has appreciated significantly and sale proceeds exceed the defeasance cost, interest rates have risen since origination (making the Treasury portfolio cheaper), you are refinancing into better terms, or the loan is close to maturity and the remaining payment schedule is short.
