Most borrowers don’t think about their commercial loan prepayment penalty until they want to sell or refinance — and then they’re staring at a bill that can reach six figures on a mid-market deal. Prepayment penalties are one of the most misunderstood terms in any commercial mortgage agreement. This guide explains how they work, which loan types use which structures, and where you actually have room to negotiate.
What Is a Commercial Loan Prepayment Penalty?
A commercial loan prepayment penalty is a fee charged by a lender when a borrower pays off a commercial mortgage before its scheduled maturity date. The logic from the lender’s side is straightforward: they structured the loan expecting a specific yield over a specific term. If you exit early, they lose that income — the penalty compensates them for it.
This is fundamentally different from residential mortgages. Federal consumer protections have largely eliminated prepayment penalties on owner-occupied home loans. In commercial lending, no equivalent rules apply. Almost every commercial mortgage carries some form of prepayment restriction, and the structure varies significantly by loan type and capital source.
The Four Main Types of Commercial Prepayment Penalties
1. Step-Down (Declining Balance)
Step-down penalties are the most borrower-friendly structure and the easiest to model into your exit strategy. The penalty is expressed as a declining percentage of the outstanding loan balance. A 5-4-3-2-1 step-down means 5% of the balance if you prepay in year one, 4% in year two, and so on — after year five the loan is open for prepayment at no cost.
This structure is common on bank portfolio loans, commercial bridge loans, and non-agency commercial products. It’s transparent and predictable.
2. Yield Maintenance
Yield maintenance compensates the lender for interest income they would have earned had the loan run to maturity. The penalty is calculated as the present value of remaining interest payments, discounted at a rate tied to comparable U.S. Treasury yields at the time of prepayment.
Per the Fannie Mae Multifamily Guide, yield maintenance is calculated as either 1% of the prepaid principal or the present value differential between the loan rate and the Treasury rate — whichever is greater. In a high-rate environment, the gap between your loan rate and Treasury yields narrows, which can actually reduce yield maintenance costs. In a low-rate environment, that gap widens and the penalty grows.
3. Defeasance
Defeasance is the standard exit mechanism for CMBS loans and certain Fannie Mae and Freddie Mac multifamily products. Instead of a cash penalty, the borrower purchases a portfolio of U.S. Treasury securities that replicate the remaining loan payment schedule. The property is released as collateral; the Treasuries take its place.
Per the Fannie Mae Multifamily Guide, defeasance typically becomes available after a 2-year lockout period following securitization. Borrowers can opt into yield maintenance at origination by paying an additional upfront fee — worth exploring if you’re planning a hold period shorter than the full term.
4. Lockout Period
A lockout period prohibits prepayment entirely for a defined window — no penalty, just a hard no. Lockouts are most common on CMBS loans (typically 2 years post-securitization) and some life company products. Once the loan closes, the lockout is not negotiable.
How Prepayment Penalties Break Down by Loan Type
| Loan Type | Common Penalty Structure | Negotiable? |
|---|---|---|
| CMBS | Defeasance or yield maintenance (2-yr lockout first) | No |
| Fannie Mae / Freddie Mac multifamily | Yield maintenance or defeasance | Limited — at origination only |
| Bank portfolio / credit union | Step-down or flat percentage | Yes |
| SBA 7(a) | 5% / 3% / 1% in years 1-3 (loans ≥15-yr maturity) | No — set by SBA |
| Bridge / hard money | Step-down or none | Often yes |
| Life company | Yield maintenance or spread maintenance | Limited |
The SBA 7(a) structure deserves a specific call-out. According to the SBA’s terms and conditions, the prepayment penalty only applies to loans with maturities of 15 years or longer, and only when the borrower voluntarily prepays 25% or more of the outstanding balance within the first three years of disbursement. The penalty structure is 5% in year one, 3% in year two, and 1% in year three — after year three, there is no prepayment penalty. Note that the SBA 504 loan carries its own separate debenture prepayment calculation, which decrements over roughly the first half of the loan term.
What This Looks Like on a Real Deal
From a recent deal: I had a client in Nashville who’d bought a 12-unit apartment building using agency financing about 18 months before they decided to sell. The loan carried a 5-year yield maintenance provision — a detail that got minimal attention at the original closing. When we ran the exit numbers, the prepayment cost came to roughly $82,000 on a $1.75 million balance. Not catastrophic, but enough to materially affect the seller’s net. The solution was a loan assumption: the buyer absorbed the existing debt rather than paying it off, the seller avoided the yield maintenance entirely, and we closed the deal. Assumption fees ran about 1% of the balance — far less than the yield maintenance would have cost. That deal is why I walk every client through the prepayment schedule in the first conversation, not the last.

Can You Negotiate a Commercial Prepayment Penalty?
It depends on the loan type. CMBS and agency loans are governed by standardized documents — the defeasance or yield maintenance calculation is fixed after closing. The only time to address prepayment on those products is at the term sheet stage, before you commit. If you’re comparing an interest-only commercial mortgage from a life company versus a bank portfolio option, the prepayment structure should be a line item in that comparison.
Portfolio lenders — community banks, credit unions, smaller life companies — have far more flexibility. I’ve negotiated step-down structures down from 5-4-3-2-1 to 3-2-1 for borrowers who made a credible case for a shorter hold period. The argument that usually lands: “We’re likely to refinance when rates shift, and a punitive exit penalty makes CMBS alternatives look attractive.” Banks that want long-term borrower relationships will often move on this.
A few other tactics worth knowing:
- Open window provision: Negotiate a 90-to-180-day open window at the end of the loan term, before the balloon payment, where prepayment is penalty-free. This protects you from having to refinance at a penalty right before maturity.
- Loan assumption for CMBS: If you’re selling, structuring the deal as a loan assumption rather than a payoff sidesteps defeasance entirely. Assumption fees typically run 1% of the balance — far less than most mid-term defeasance scenarios.
- Partial prepayment provisions: Some step-down loans allow partial prepayments above a certain threshold without triggering the penalty on the full outstanding balance. Check how the penalty trigger is defined in your loan documents.
Frequently Asked Questions
What is the typical prepayment penalty on a commercial loan?
It varies by loan type. Bank portfolio loans typically use step-down structures like 5-4-3-2-1 percent of the outstanding balance. CMBS and agency loans use yield maintenance or defeasance, which are formula-driven and can cost substantially more on a mid-term exit. SBA 7(a) loans use a 5%/3%/1% schedule in years one through three for loans with maturities of 15 years or longer, with no penalty after year three.
Is there always a prepayment penalty on a commercial mortgage?
Almost always, yes. Unlike residential mortgages, commercial loans are not subject to consumer protection rules limiting prepayment restrictions. Short-term bridge loans are the most common exception. Before signing any commercial mortgage, review the prepayment schedule carefully and understand the cost at several different exit points during the loan term.
What is the difference between yield maintenance and defeasance?
Both are designed to make the lender whole for lost interest income, but they work differently. Yield maintenance is a cash payment calculated as the present value of remaining interest, discounted at a Treasury-based rate. Defeasance replaces the property collateral with a portfolio of U.S. Treasury securities rather than requiring a direct cash payment — the lender still receives the same income stream, backed by government bonds instead of your property.
