Why It Matters
How does a step-down prepayment penalty work on investment loans? If you pay off the loan in year 1, you owe 5% of the remaining balance. In year 2, the penalty drops to 4%; year 3, 3%; and so on until it hits zero after year 5. On a $600,000 balance, a year-2 payoff triggers a $24,000 penalty — real money that must be underwritten before you decide to refinance or sell.
At a Glance
- Common in DSCR loans, CMBS securities, and portfolio lender products
- Standard schedule: 5% / 4% / 3% / 2% / 1%, then zero after year 5 (or 6+)
- Penalty is calculated on the outstanding loan balance at time of payoff
- No penalty once the step-down period expires
- Differs from yield maintenance — yield maintenance is more punitive and ties the penalty to current Treasury rates
- Often called a "soft prepayment penalty" (as opposed to hard lockout, which prohibits payoff entirely)
- Typically does not apply to partial principal curtailments, only full payoff or refinance
How It Works
The step-down structure exists because lenders front-load costs: origination, underwriting, commissions, and rate lock hedges all get paid at closing. When a borrower pays off early, the lender loses the interest income those costs were priced against. The penalty deters early exits during the window when the loan is most profitable.
How the math works: The penalty is a flat percentage of the unpaid principal balance (UPB) at the time of payoff. If the loan balance is $1,187,000 in year 3 and the step-down schedule reads 3% for that year, the penalty is $35,610. That number gets paid at closing out of sale or refinance proceeds, so it reduces the net gain on the transaction.
Year-by-year schedule (5-year example):
- Year 1: 5% of UPB
- Year 2: 4% of UPB
- Year 3: 3% of UPB
- Year 4: 2% of UPB
- Year 5: 1% of UPB
- Year 6+: No penalty
Some lenders run 3-year schedules (3-2-1%) or extend to 10 years with slower step-downs. Always read the Note — schedules vary by lender and product.
When it triggers: Refinancing into a new loan, selling the property, paying off the balance with a cash-out from another asset, or any event that causes the loan to be retired before the step-down period ends. It does not usually apply to normal amortization payments.
Step-down vs. yield maintenance: Yield maintenance is the more aggressive cousin. It calculates the penalty based on the present value of the lender's lost interest income, discounted at the current Treasury rate. In a low-rate environment, yield maintenance penalties can be massive. Step-down is simpler and more investor-friendly — the cost is fixed at origination and requires no Treasury rate assumptions.
Where you'll find it: DSCR loans, non-QM investment products, commercial bank portfolio loans, and CMBS conduit products. It's standard on most fixed-rate investment property products with terms under 30 years.
Calculating before you exit: Compare the penalty against the benefit. If refinancing saves $1,800/month in interest, a $35,000 penalty breaks even in roughly 20 months — after that, every month is profit.
Real-World Example
Rachel owns a 12-unit apartment building in Columbus, Ohio, financed with a $1,243,000 DSCR loan at 7.1% on a 5-year step-down schedule. She closes in early 2023.
By late 2025 — just under three years in — rates have dropped to around 6.2%, and her lender rep is pitching a refinance. The new rate would cut her debt service by roughly $690 per month. She pulls up the Note.
Year 3 on the schedule reads 3%. Her outstanding balance is $1,219,400. The penalty: $36,582.
Break-even: $36,582 ÷ $690/month = 53 months. That's over four years just to recover the exit cost — and Rachel already plans to sell in 2028 when her depreciation runway runs thin. Refinancing now would cost $36,582 to save roughly $24,840 before the sale. A net loss of $11,742.
She passes. Rachel holds the loan until year 5, when the penalty drops to 1% ($12,194), and reassesses then. The step-down schedule isn't a trap — it's a number that has to fit the math.
Pros & Cons
- Predictable cost: Unlike yield maintenance, the step-down amount is calculable at origination — you know the exact dollar figure for every exit year before signing
- Declining obligation: The penalty shrinks annually, rewarding longer holds and aligning with most buy-and-hold strategies
- Better than a hard lockout: A hard lockout prohibits payoff entirely during the restricted period; step-down just prices it
- Enables better rates: Lenders offer more competitive pricing when they have prepayment protection — the borrower trades the penalty structure for a lower rate
- Real exit cost: Even a 2% penalty in year 4 can mean tens of thousands of dollars on a larger loan — enough to flip a refinance from profitable to break-even
- Limits opportunistic refinancing: If rates drop sharply early, a 5% or 4% penalty can make refinancing unprofitable
- Must be underwritten at acquisition: Investors who skip modeling the step-down cost get surprised at closing — the penalty comes out of proceeds
Watch Out
Confusing step-down with yield maintenance. Yield maintenance is not a fixed percentage — it's a formula tied to Treasury rates that can produce penalties far larger than any step-down schedule. Before signing any loan with prepayment language, identify exactly which structure applies.
Ignoring it in acquisition underwriting. The prepayment penalty must appear as a line item in every exit scenario — sale, refinance, or cash-out. Investors who skip this step sometimes arrive at closing to find a deal they expected to profit from has a negative net return.
Conflating the step-down period with loan seasoning. Loan seasoning refers to how long a loan has been on the books for eligibility purposes (e.g., cash-out refinance requirements). The step-down period is purely a prepayment penalty clock. Both run simultaneously — they are separate concepts.

The Takeaway
Step-down prepayment penalties are a standard feature of investment property financing — not a red flag, but a number that must be modeled. Underwrite the penalty into every exit scenario at acquisition, compare it against projected savings before any refinance decision, and time major moves around the schedule when possible. Once the period expires, the loan is yours to retire on your own terms.
