Prepayment Penalties on Bridge and Fix-and-Flip Loans: The Minimum-Interest Clause Most Borrowers Miss
You close a bridge loan in October, plan on a six-month hold, and the buyer shows up in month two with cash. Good news for the deal, except your payoff statement has four months of interest on it that you didn’t borrow for. That’s not a mistake on the statement. It’s the minimum-interest clause, and it’s in almost every short-term, asset-based loan — fix-and-flip, bridge, ground-up construction — even though none of those loans carry the kind of prepayment penalty a rental-property loan does.
Why short-term loans skip the penalty DSCR loans use
A DSCR rental loan is underwritten to sit on a balance sheet (or get sold into a security) for years, so the lender prices in a multi-year step-down prepayment penalty — often 5% in year one, declining a point a year — to protect that expected yield. A fix-and-flip or bridge loan is priced the opposite way: the lender expects you gone in 12 to 18 months and wants the capital back fast to redeploy it. A multi-year penalty would work against that. So instead of a step-down schedule, our loan programs on the short-term side typically use a minimum-interest guarantee: a floor number of months of interest you owe no matter when you pay off, usually three to six months, specified in the term sheet and loan documents.
The arithmetic: what a 6-month floor actually costs you
Say you close a $500,000 bridge loan at an indicative 11% rate, interest-only, with a six-month minimum-interest guarantee. Monthly interest on that balance is:
$500,000 × (11% ÷ 12) = $4,583.33 per month.
If you pay the loan off in month two — refinance into a DSCR rental loan, or sell the property — you don’t just owe two months of accrued interest. You owe the greater of (a) interest actually accrued, or (b) the six-month floor. Four months of interest you didn’t use:
4 months × $4,583.33 = $18,333.33 in additional interest, on top of the roughly $9,166.66 you’d already accrued for months one and two.
That $18,333 is real money that doesn’t show up in most back-of-envelope flip budgets, and it’s the single most common surprise line item on a payoff statement. Rates, guarantee length and exact terms are indicative and set per deal, subject to underwriting and credit approval — this is the arithmetic pattern, not a quote.
The three structures, and where each one actually shows up
“Prepayment penalty” gets used loosely to describe three different mechanisms. They aren’t interchangeable, and knowing which one is in your term sheet changes how you plan the exit.
| Structure | How it’s calculated | Where it typically shows up |
|---|---|---|
| Minimum-interest guarantee | Flat floor of 3–6 months’ interest, regardless of actual payoff date | Fix-and-flip, bridge, ground-up construction |
| Step-down penalty | Percentage of unpaid principal, declining year over year (e.g., 5-4-3-2-1) | DSCR rental loans, longer-term holds |
| Yield maintenance | Lender’s lost yield calculated against a replacement benchmark rate | Larger multifamily bridge loans, rarely on single-property fix-and-flip |
This is the detail that doesn’t transfer between loan types. A DSCR loan’s step-down penalty runs for years because the loan itself runs for up to 30 years; a fix-and-flip loan’s minimum-interest floor runs for months because the loan itself is designed to be gone within 12 to 18 months. Treat them as the same clause and you’ll either budget for a penalty that doesn’t apply to your flip, or get blindsided by one that does. On a larger multifamily bridge loan you may see yield maintenance layered on top of a shorter minimum-interest floor rather than instead of it — ask which applies, and get it in writing in the term sheet, not just the verbal quote.
Where to actually find this clause
It’s rarely called out on the one-page term sheet summary. Look for it in the note itself, usually under a heading like “Minimum Interest” or “Prepayment,” and read the exact month count — not the loan term. A 12-month bridge loan with a 3-month minimum-interest floor behaves very differently at a month-2 payoff than the same loan with a 6-month floor. If the document only says “prepayment permitted” with no floor stated, ask in writing before you fund; silence on this point usually means the floor is buried in a cross-reference elsewhere in the note, not that there isn’t one.
Where it gets negotiated, and where it doesn’t
The guarantee length is usually set by loan size and program, not by borrower request — a $150,000 fix-and-flip loan and a $3,000,000 ground-up construction loan won’t carry the same floor. What you can control is timeline planning: if you’re structuring a flip you genuinely expect to close in under 60 days — a cosmetic rehab on a hot block, already under contract to a buyer — ask about the guarantee length before you sign, because a six-month floor on a two-month flip is a real, quantifiable cost you should build into your spread, not a penalty you negotiate away after the fact.
When this is the wrong call
If your business plan depends on turning capital in under 90 days repeatedly — wholesale-style flips, fast BRRRR cycles — the minimum-interest floor compounds against you every time you exit early, and it’s worth running the arithmetic above against your actual expected hold period before you commit to a specific loan size and rate. In that case, a shorter guarantee period, even at a slightly higher rate, can beat a lower rate with a longer floor once you run the breakeven math. And if you’re refinancing a rental out of hard money, check the DSCR program terms separately — that payoff triggers its own seasoning and prepayment math, not this one.
None of the figures above are offers or guarantees — every rate, guarantee length and term is set per deal, subject to underwriting and credit approval. Check current terms on our rates page, or get specifics on a live file through the bridge or fix-and-flip program pages before you size your exit.
