The quick read: When a fix and flip loan reaches its maturity date before the house sells, the whole unpaid balance comes due anyway, and if you cannot pay it off, the default terms written in your own note can apply. The realistic routes are a price cut and a sale, an extension from your current lender, or a refinance into a bridge or DSCR rental loan, and each one works best when you start it before the date arrives rather than after it.
A fix and flip loan is short-term money with one planned exit: finish the renovation, sell, and repay from the sale proceeds. NerdWallet describes hard money repayment terms as running anywhere from a few months to a few years, and notes that high rates combined with short terms can make these loans harder to repay than other financing. When the renovation runs long or the listing sits, the calendar keeps moving. This article describes mechanisms, not legal advice: the remedies that apply to you are written in your loan documents, and a real estate attorney in the property's state is the person to read them with you.
What happens on the maturity date of a fix and flip loan?
On the maturity date of a fix and flip loan, the entire unpaid principal is due in one payment, so a finished but unsold house does not pause the clock; the note decides what happens next. Corporate Finance Institute notes that a missed or late payment is typically an event of default in most loan agreements.
If your note is interest-only, which is worth confirming on page one of it, the full principal is a balloon payment: Corporate Finance Institute defines a balloon payment as a large payment due at the end of a loan term. A loan paid on time every month can still default on one day, because those payments never touched the principal.
Maturity date: the day the unpaid principal is due in full.
Event of default: whatever your loan agreement defines as one. Corporate Finance Institute's list includes non-payment or late payment of principal or interest, covenant breaches, and changes in ownership or control.
Remedies: the lender's rights after a default are set out in your note and security instrument. NerdWallet puts the end point plainly for hard money borrowers: if you cannot repay, the lender has the right to seize the collateral.
Corporate Finance Institute describes foreclosure as a specific legal process that transfers title back to a lender for the purpose of selling the property. How it would run on your loan is a question for your attorney.
What are your options if the flip has not sold by maturity?
You have five practical routes when a flip will not sell before its maturity date: cut the price and close a sale, negotiate an extension with the current lender, refinance into a new bridge loan, refinance into a DSCR rental loan once the house is leased, or work out new terms after maturity has already passed.
Where a cell carries a rate, it is dated and sourced; where no public figure exists, the cell says so, because extension fees and default rates are lender-specific terms written into each note.
| Route | What it costs | Timing | Source (dated) |
|---|---|---|---|
| Sell at a lower price | The price concession plus your selling and closing costs; no published norm | Needs a closed sale before the maturity date | Your listing agent's pricing; no public standard |
| Extension from the current lender | The extension fee and any rate step-up written into your note or the lender's approval letter; no public standard figure | Request before maturity; ask whether it is a right or a discretionary approval | Your loan documents |
| Refinance into a new bridge loan | New origination and closing costs; ask whether the rate floats over SOFR, 3.87% as of 2026-09-23, or bank prime, 7.00% as of 2026-09-21 | Full new underwriting, valuation and title; start well before maturity | FRED SOFR and DPRIME series |
| Refinance into a DSCR rental loan | New loan costs; sized on rental income against the new payment rather than on a sale | Ask whether the lender sizes it on a signed lease or on market rent | Agencies' illustration in bank supervisory guidance: 2023 interagency policy statement, spec home example (renting an unsold home), published July 6, 2023 |
| Workout after maturity | The note's default terms, which can include a higher penalty rate on the remaining balance | Starts only after the missed payoff | Federal Reserve SR 23-5 (bank supervisory guidance), June 30, 2023; CFI default rate guide, August 12, 2020 |
| Brokerage (YieldStack, publisher of this page) | It costs Zero upfront to submit a deal and review offers; YieldStack's broker fee is 0.50–1.00% of the loan amount and is paid only at closing. | 5-minute submit | Publisher's own terms, disclosed |

How does a fix and flip loan extension work?
A fix and flip loan extension is a written change that moves the maturity date later, and its price, its conditions and whether you are entitled to it at all are set by your loan documents or by the lender's approval, so the extension clause deserves a careful read long before the rate does.
There is no public standard for extension pricing on flip loans, so this article does not quote one. What you can do is ask the questions that decide the cost before you need the answer:
- Is the extension an option you can exercise if stated conditions are met, or a request the lender may decline?
- What fee is charged, and is it calculated on the original commitment or on the outstanding balance?
- Does the interest rate change during the extension period?
- What conditions apply: no existing default, payments current, a new valuation, a principal paydown, an updated budget?
- How far ahead of maturity must the request be made, and in what form?
- Does a guarantor have to sign the extension again?
A paydown is one condition to ask about. In one of the illustrative examples in the 2023 interagency policy statement on commercial real estate loan workouts, supervisory guidance for banks and credit unions, a land borrower made a principal payment in exchange for a 12-month extension. The agencies state that their examples are provided for illustrative purposes only, so treat it as one way a negotiation can be shaped, not as a price list.
An extension does not stop interest, taxes, insurance or utilities. The full cost stack of a flip loan, including where extension fees sit in it, is laid out in how fix and flip loans work and what they cost.
What does default interest mean if you miss the maturity date?
Default interest is a higher rate that a loan agreement can switch on after a delinquency or other event of default, and where a flip loan's note carries one, a missed maturity date can make every week of waiting for a buyer after that date cost more than a week before it did.
Corporate Finance Institute describes the mechanism in general terms, in the context of routinely missed or late payments: "One strategy a lender may implement is to increase the interest rate on the borrower's remaining loan after delinquency. The substantially higher interest rate is referred to as the penalty rate. The lender may decide to lower the penalty rate if the borrower successfully makes on-time payments."
Whether your note carries a default rate, how much higher it is, what triggers it, and whether late charges or legal costs are added on top are all specific to your documents. Read them before maturity and ask the lender directly:
- Does a missed maturity payoff trigger the default rate automatically, or only after notice?
- Does the default rate apply to the full unpaid balance or only to the overdue amount?
- Would the lender waive default interest as part of an agreed extension or payoff date?
Get the answers in writing, and ask the lender for a written payoff figure for the maturity date: that is the number a buyer's closing agent or a refinance lender will need to retire the loan.
Can you refinance a finished flip into a DSCR or bridge loan instead?
You can refinance a finished but unsold flip into a new loan, but the new lender underwrites it from scratch, so start while there is still time for a valuation, title work and a credit decision; a refinance that closes after maturity pays off a loan whose default terms may already be running.
A DSCR loan is sized on the property's rental income against the loan payment, so it fits a flip you are prepared to hold and rent. Ask the lender whether it will size the loan on a signed lease or on an appraiser's market-rent estimate, because that decides whether a tenant has to be found before the refinance can close. The 2023 interagency policy statement, supervisory guidance for banks and credit unions, illustrates this turn in one of its examples for examiners: the lender restructures an unsold spec home loan for a year, and when the borrower rents the house, the debt is restructured again into monthly payments that amortize over 20 years at a market interest rate for a residential investment property.
A new bridge loan buys time rather than a permanent answer. It can pay off the flip loan and give you a fresh term to sell, but it carries new origination and closing costs, and it has its own maturity date. Ask any bridge lender whether its rate floats over SOFR or prime, what its own extension terms are, and what it will lend against the finished value.
If the original flip lender declined to extend, the reasons it gave are useful in the refinance package. Declined for a fix and flip loan covers how to read a no and what to change before the next submission.
How do bank regulators describe a bank working with a flip that did not sell?
Federal bank regulators addressed this situation in their 2023 interagency policy statement on commercial real estate loan accommodations and workouts, supervisory guidance for banks and credit unions whose appendix illustrates a single-family spec home loan that reached maturity completed but unsold, with scenarios showing a restructure, a rental conversion and a loan that went past due.
The Federal Reserve's SR 23-5 letter, dated June 30, 2023, says the regulators adopted the statement to reinforce that financial institutions should work prudently and constructively with creditworthy commercial borrowers experiencing financial difficulties. The statement applies to institutions supervised by the Federal Reserve, the FDIC, the NCUA and the OCC, so it describes how banks and credit unions are examined, not how a private flip lender must behave.
The statement published in the Federal Register on July 6, 2023 lists the forms a workout at a supervised institution can take, including renewing or extending loan terms, granting additional credit to improve prospects for overall repayment, or restructuring the loan with or without concessions.
Its spec home example is the agencies' illustration of a situation that resembles a flip gone long. The base case is a $1.2 million construction loan on a single-family spec residence with a 15-month maturity; at maturity the home was completed but not sold, and the borrower could not find another lender willing to finance it on similar terms. In the agencies' scenarios, the lender restructures the loan for one year on an interest-only basis, and the outcome depends on what happens next: the house is rented and the loan restructured into an amortizing one, or it stays unsold, the loan goes more than 90 days past due, and repayment becomes contingent on a sale. These are the agencies' illustrations of examiner reasoning, not terms any lender is obliged to offer you.
In what order should you negotiate when maturity is close?
Negotiate in the order that keeps the most options open: price the sale honestly, ask the current lender for an extension in writing, and run a refinance in parallel, all before the maturity date, because once the loan is past due, default terms may apply.
- Pull your loan documents and find four things: the maturity date, the extension clause, the default rate, and the notice provisions.
- Reprice the house against current comparable sales and decide the lowest price at which a sale beats the cost of holding.
- Ask the current lender, in writing, what an extension would require and cost, and request a payoff figure for the maturity date.
- Start a refinance in parallel: a bridge loan if you still plan to sell, a DSCR loan if you are ready to rent.
- Compare the full cost of each path for the same number of months, including carrying costs, not only the fee.
- If maturity is going to pass anyway, talk to the lender before it does, and have an attorney review any forbearance or modification agreement before you sign it.
How do you get lenders competing for the refinance on an unsold flip?
You get lenders competing for the refinance on an unsold flip by sending one complete file to several lender types at once, early enough that a bridge lender and a DSCR lender can both quote before the current loan matures, and by comparing their term sheets side by side rather than one after another.
YieldStack is a commercial mortgage brokerage, not a lender. It costs Zero upfront to submit a deal and review offers; YieldStack's broker fee is 0.50–1.00% of the loan amount and is paid only at closing. Every credit decision is made by the lender; YieldStack arranges the introductions and negotiates on the borrower's side, and no loan, rate, or closing is guaranteed.
A refinance file for a finished flip should carry the current payoff figure, the maturity date, the completed scope of work with photos, the listing history, any signed lease, and your plan: sell with more time, or hold and rent. Submit the refinance on your unsold flip and compare the terms lenders are willing to offer before the maturity date arrives.
The bottom line
A fix and flip loan does not wait for the market: on the maturity date the balance is due, and a missed payoff can bring in whatever penalty rate and remedies your note contains. Read the extension and default clauses now, get the lender's answers in writing, and start a bridge or DSCR refinance in parallel while there is still time to underwrite it.
