Defeasance: Escaping Your Fixed-Rate Lock

How to prepay a Freddie Mac loan by substituting Treasury securities—and when the math actually works.

Definition

Defeasance: A prepayment method that releases the property from the mortgage lien by substituting a portfolio of U.S. Treasury securities sufficient to make all remaining loan payments, effectively "defeating" the borrower's obligation while the loan continues to maturity.

You locked in a 5.5% fixed rate when rates were rising. Now rates have dropped to 4.25%, and you want out. Or you've found a buyer willing to pay a premium for your property, but they don't want to assume your loan. The problem: your Freddie Mac loan has a lockout period followed by defeasance requirements. Here's how to navigate the escape hatch.

How Does Defeasance Work?

Defeasance doesn't actually prepay your loan—it substitutes the collateral:

  1. You purchase Treasury securities that will make each remaining loan payment (principal + interest) exactly when due
  2. These securities replace your property as collateral for the loan
  3. The lien on your property is released, allowing you to sell or refinance
  4. A successor borrower (typically an SPE created by the defeasance consultant) takes over the loan
  5. The loan continues to maturity, paid by the Treasury portfolio

The lender receives exactly what they were promised—all payments on schedule. You get your property back, free and clear.

Defeasance vs. Yield Maintenance vs. Prepayment Penalty

Key Point
Most Freddie Mac SBL loans have a structure like: 2-year lockout → defeasance until final 90 days → open period. Check your loan documents for the exact structure—it varies by product and vintage.

The Defeasance Cost Components

1. Treasury Portfolio Cost

The biggest cost: purchasing Treasuries to replicate remaining payments. This cost depends on:

  • Remaining loan balance: Larger balances = larger portfolios
  • Remaining term: More payments to replicate = more bonds needed
  • Interest rate environment: If rates have dropped, Treasuries cost MORE than remaining payments (premium). If rates have risen, they cost LESS (discount)

Example: Rate Environment Impact

Loan terms: $4M balance, 5.5% rate, 7 years remaining

If current Treasury yield is 4.0%: You must buy Treasuries at a premium to generate 5.5% cash flow. Cost: ~$350,000 above par.

If current Treasury yield is 6.5%: Treasuries are cheaper because they yield more. Cost: ~$280,000 below par savings offset portfolio cost.

2. Defeasance Consultant Fee

Third-party specialists manage the process:

  • Portfolio structuring: Designing the exact Treasury mix
  • Successor borrower: Setting up the SPE that takes the loan
  • Coordination: Managing lender, servicer, attorneys

Typical fees: $25,000-$75,000 depending on loan size and complexity

3. Legal Fees

Multiple attorneys involved:

  • Your attorney (borrower counsel)
  • Lender's counsel
  • Successor borrower counsel
  • Rating agency counsel (for securitized loans)

Typical total: $30,000-$100,000

4. Servicer and Rating Agency Fees

  • Servicer consent fee: $5,000-$15,000
  • Rating agency fees: $10,000-$25,000 (if loan is securitized)

5. Accounting and Tax Advisory

  • Tax structuring: Minimizing recognition of gain
  • Accounting treatment: Proper book treatment of the transaction

Typical fees: $5,000-$25,000

Warning
Treasury prices move daily. You won't know your final defeasance cost until you lock the portfolio, typically 3-5 days before closing. Budget for variance—rates can move significantly over a 60-90 day process.

When Does Defeasance Make Economic Sense?

Scenario 1: Selling the Property

Your buyer wants clean title (no loan assumption):

ItemAmount
Sale price$7,500,000
Loan balance($4,200,000)
Defeasance cost($380,000)
Closing costs($150,000)
Net proceeds$2,770,000

Compare to waiting until the open period: If you'd net $2.9M by waiting 18 months for the open period, but the buyer is offering a premium now, the math may favor defeasance.

Scenario 2: Refinancing to Lower Rate

Rates have dropped and you want to capture savings:

ItemCurrent LoanNew Loan
Balance$4,200,000$4,200,000
Rate5.50%4.25%
Annual debt service$312,000$268,000
Annual savings$44,000

If defeasance costs $350,000 and you'll save $44,000/year for 7 remaining years, you break even in 8 years—longer than the loan term. In this case, defeasance doesn't make sense. But if the rate differential is larger or the remaining term is shorter, the math can work.

The Break-Even Formula

Break-even period = Defeasance cost ÷ Annual savings

If break-even period < remaining term, refinancing via defeasance is profitable.

If break-even period > remaining term, keep the existing loan.

Defeasance and 1031 Exchanges

Defeasance creates complications for 1031 exchanges:

  • Timing pressure: 45-day identification and 180-day closing windows don't flex for defeasance timelines
  • Cost allocation: Defeasance costs may or may not be includable in exchange basis
  • Boot concerns: Structure carefully to avoid taxable boot

If you're planning a 1031 exchange, engage your defeasance consultant and exchange accommodator simultaneously, and allow extra time.

Alternatives to Defeasance

Loan Assumption

If you're selling, the buyer may assume the loan:

  • Pro: Avoids defeasance cost entirely
  • Pro: Buyer gets your favorable rate
  • Con: Buyer must qualify under Freddie Mac standards
  • Con: 1% assumption fee still applies

Wait for Open Period

If you can wait, the final 90 days before maturity have no penalty:

  • Pro: Zero prepayment cost
  • Con: Must time your transaction to the open window
  • Con: Market conditions may change while waiting

Supplemental Loan Instead

If you need capital but don't need to exit the loan, a supplemental loan may work:

  • Pro: Access equity without prepaying first mortgage
  • Pro: Preserve your favorable rate
  • Con: Additional debt service
  • Con: Must qualify under combined metrics

Selecting a Defeasance Consultant

Key factors when choosing a consultant:

  • Experience: How many defeasances have they completed?
  • Lender relationships: Do they know your servicer's process?
  • Bond desk relationships: Can they get competitive Treasury pricing?
  • All-in fee transparency: Beware hidden costs and markups
  • Timeline track record: Can they meet your deadline?

Major defeasance consultants include Chatham Financial, Commercial Defeasance, and AST Defeasance. Get quotes from at least two.

Insider Terminology

Successor Borrower
The SPE (special purpose entity) that takes over the defeased loan, with the Treasury portfolio as its only asset. Created by the defeasance consultant.
Treasury Portfolio
The combination of U.S. Treasury securities structured to exactly replicate all remaining loan payments—principal and interest—through maturity.
Lockout Period
The initial period (often 2 years) during which no prepayment is permitted at all—not even through defeasance.
Open Period
The final 90 days before maturity when prepayment is permitted without penalty. The cheapest exit window.
Defeasance Consultant
Third-party specialist who structures the Treasury portfolio, manages the process, and creates the successor borrower entity.

Key Takeaways

Bottom Line
  • Defeasance substitutes collateral: Treasuries replace your property, releasing the lien
  • Cost depends on rate environment: Falling rates increase defeasance cost
  • 60-90 days minimum: Start early when you decide to sell or refinance
  • Run the math: Break-even analysis determines if defeasance makes sense
  • Consider alternatives: Assumption, supplemental loans, or waiting for open period may be better
