Divorce House Buyout in 2026: How to Pay Out Your Ex Without Giving Up Your Low Mortgage Rate

The Assumption That Costs Divorcing Homeowners the Most

The worst assumption I see in divorce files is that keeping the house means refinancing the mortgage. Someone signs a settlement agreement that says they'll buy out their former spouse's share of the home, and the next call is to a lender about a cash-out refinance, because a cash-out refinance is the tool the settlement conversation usually points to. If the first mortgage carries a rate from a few years back, that one call can cost more than the buyout itself.

Put the gap in numbers. Freddie Mac's most recent weekly survey put the 30-year fixed average at 6.76%. If you're sitting on a 3.25% first mortgage with a $300,000 balance, the first year of interest runs roughly $9,700. Replace that loan with a new $300,000 first mortgage at 6.76% and the first year of interest runs roughly $20,200, more than double, and that's before you've financed a dollar of the payout.

I spent my first years in this business originating loans, and these days I run processing, where the file arrives after the borrower has already picked a product. Divorce buyouts are a file type my team at AmeriSave sees regularly, and they've taught me to treat the buyout as three problems arriving together. You need three things: money to pay your former spouse, your former spouse's name off the title, and your former spouse's name off the mortgage note. A cash-out refinance solves all three in one closing, which is why it's the default, and it charges you the full rate gap for the convenience.

There are two other ways through. A home equity loan or HELOC funds the payout as a second lien and leaves the first mortgage untouched. An assumption or a release of liability takes your ex off the note without any new loan. Each path solves a different set of the three problems, and the gap between the rate you have and the rate the market would charge you does most of the deciding.

The Deed and the Note Are Two Different Documents

Start with the house. A standard mortgage contract includes a due-on-sale clause, which lets the lender demand full repayment if the property changes hands. Federal law, the Garn-St Germain Act, limits when a lender can use that clause, and one of its exemptions is written for exactly this situation. A lender can't call the loan due because of "a transfer resulting from a decree of a dissolution of marriage, legal separation agreement, or from an incidental property settlement agreement, by which the spouse of the borrower becomes an owner of the property." In plain terms, when your ex signs their interest in the house over to you under the decree, that transfer alone gives the lender no grounds to accelerate the mortgage.

Now the note. The statute protects the title transfer and says nothing about who owes the debt. If both of you signed the promissory note, both of you remain liable on it after the deed is recorded and the decree is final. The CFPB's mortgage glossary defines a refinance as a new loan that pays off and replaces the old one, and defines a loan assumption as one party taking over an existing mortgage after a credit and income review similar to qualifying for a new loan. Those two mechanics, plus a release of liability negotiated with the servicer, are how a name comes off a note. A deed does none of that work.

From a processing desk, the gap between those two documents shows up as a specific type of file: a former spouse who moved out two years ago and is still the co-borrower whose credit takes the hit if a payment slips. The decree may order you to refinance by a certain date and may order you to hold your ex harmless for the debt, but your lender didn't sign the decree. The decree binds the two of you. It doesn't bind the loan.

So the honest map has three columns. Money for the payout can come from savings, from a cash-out refinance, or from a second mortgage, the glossary's term for a loan that uses your house as collateral while another loan secured by the house stays in place, which in practice means a home equity loan or a HELOC. Title comes to you through a deed prepared under the decree, with Garn-St Germain protecting the mortgage while it moves. And your ex comes off the note through a refinance, a lender-approved assumption, or a release of liability. The path that protects your rate fills the first two columns without touching the first mortgage.

Path One: Keep the First Mortgage and Fund the Buyout With a Second Lien

Your 3.25% first mortgage stays put. You add a home equity loan or a HELOC for the buyout amount, the proceeds go to your former spouse at closing, and the deed transfers under the decree. The new loan records behind the first as a second lien, so the first mortgage's rate, balance, and schedule don't change.

Which second lien fits comes down to a question I've used for years on equity-access decisions: is the money already spent, or not yet spent? A divorce buyout is the purest form of already-spent money I can think of. The amount is fixed by the settlement, it's owed to one person, and it's due on a date. Money that's already spent points toward a fixed-rate home equity loan, because you're going to amortize the full balance anyway, and a fixed schedule does that with no surprises on the payment line. If you're comparing an AmeriSave home equity loan against a HELOC for a buyout, the already-spent question is the one I'd start with.

A HELOC's rate floats with a public index, most often the prime rate plus a margin the lender sets, and the Federal Reserve's H.15 release put the bank prime loan rate at 6.75% in its most recent weekly figure. Many HELOCs let you pay interest only during the draw period, which makes the monthly number look friendlier while the balance sits still. On a $150,000 draw at an illustrative 8%, interest-only comes to $1,000 a month and retires nothing. A $150,000 home equity loan at the same illustrative 8% over 15 years runs about $1,433 a month, and the balance is gone at the end. Both rates are illustrations, since no government source publishes a weekly home equity rate, and your quote will depend on your credit, your combined loan-to-value, and the lender.

That's the simple version. A HELOC earns its place in two divorce situations. If the settlement pays your ex in installments over several years rather than one check, a line lets you draw each installment when it's due and pay interest only on what's out. And if the house needs work before you can carry it alone, or you want a reserve for the first year on one income, the redraw feature has value a closed-end loan can't offer.

Two things path one doesn't solve. The lender's combined loan-to-value limit on a second lien caps how much equity you can reach, and the appraisal sets the value that limit runs against, whatever number the settlement assumed. And your former spouse is still on the first mortgage note. You'll pair this path with an assumption or release, which I'll get to, or the two of you will accept that they stay on the note with the decree's hold-harmless language as their protection. That second choice is a conversation for your family law attorney as much as your lender.

Path Two: A Cash-Out Refinance the Rules Treat as Limited Cash-Out

A refinance pays off and replaces the first mortgage. In the buyout version, a new $450,000 loan retires the $300,000 first, sends $150,000 to your former spouse through the settlement statement, and puts your name alone on the new note. It fills all three columns at once, and it does so by trading the 3.25% rate for whatever the market charges the day you lock.

One piece of this leg changes the price, and it comes from Fannie Mae's Selling Guide. Normally a refinance that hands cash to anyone at closing is a cash-out refinance, and cash-out refinances typically carry their own pricing adjustments on top of the base rate. Section B2-1.3-02 of the Selling Guide says a transaction in which one owner buys out another owner's interest, and it names a divorce settlement as the example, can be treated as a limited cash-out refinance instead, provided the file meets five conditions. The property was jointly owned for at least 12 months before the new loan's disbursement date. All parties sign a written agreement stating the terms of the transfer and how any refinance proceeds will be disposed. The joint ownership is documented. The party buying out the other qualifies under standard underwriting. And the party ending up as sole owner receives no proceeds beyond the payoff and the buyout itself.

Read those five conditions the way a processor reads them, because each one is a document in your file. The written agreement is your settlement agreement or decree, and it has to say who receives what. The disbursement to your ex goes straight onto the settlement statement, payable to them. And the last condition is the one that trips people. If you pull an extra $20,000 for yourself to cover moving costs or attorney fees, the transaction becomes a standard cash-out refinance in Fannie Mae's eyes, with cash-out pricing. Ask your loan officer, at AmeriSave or anywhere else, which treatment your file will receive before you compare quotes, because the answer moves the rate.

The size of that pricing adjustment is set by lender and investor pricing, so I won't put a number on it. The limited cash-out treatment narrows the gap between path two and path one, and whether it closes that gap depends on how far your first mortgage sits below the market. In the example below I priced the cash-out at 6.5%, under the 6.76% Freddie Mac average, and the kept first mortgage still came out ahead by a wide margin.

Path two wins in a few situations. If your first mortgage is already near market, the rate gap that makes path one work has nothing to protect. If the buyout is large relative to the first mortgage and the lender's second-lien loan-to-value limits can't reach it, the refinance may be the only loan that funds the payout. And if the decree requires your ex off the note by a date and the servicer won't release them, the calendar decides for you.

Path Three: Assumption or Release of Liability

The third path removes your former spouse from the note without any new money at all. In a divorce, an assumption means taking sole responsibility for a loan you already signed, at the same rate and schedule, with the servicer reviewing your credit and income alone, much as it would for a new loan.

Some loan types allow another qualified borrower to formally assume the loan, and some servicers offer a release of liability that accomplishes the same thing. Availability depends on your loan and your servicer, so the first call belongs to the servicer named on your statement. Ask whether assumption or a release of liability is available on your specific loan, what the qualification review looks like, and how long the process runs. Get the answer in writing, because decrees often carry deadlines.

What path three solves is the note. What it can't do is write the check. Nothing about an assumption produces the $150,000 your former spouse is owed. So the strongest keep-the-rate combination, when the servicer allows it, is path three plus path one: a release or assumption on the first mortgage, and a home equity loan for the payout, which fills all three columns and leaves the 3.25% rate where you found it. If the servicer says no, you're choosing between path one with your ex still on the note and path two.

The Same $150,000 Buyout, Two Ways

Numbers settle this faster than rules do, so I ran one buyout both ways. Assume the house appraises at $600,000 and the first mortgage has a $300,000 balance at 3.25% with 25 years left, which puts the payment at about $1,462 a month. That leaves $300,000 in equity, and the settlement splits it evenly, so the buyout is $150,000. Every rate here is an illustration chosen for clean math, and none of them is a quote.

Path one keeps the first mortgage and adds a $150,000 home equity loan at 8% fixed over 15 years, about $1,433 a month. Combined, you'd pay about $2,895 a month.

Path two replaces everything with a $450,000 cash-out refinance at 6.5% over 30 years, about $2,844 a month.

Get Started

Look at those two payments first, because payment shock is the outcome I'd want you to minimize, and on that measure the paths are nearly identical. Your monthly obligation rises by about $1,433 on path one and by about $1,382 on path two, roughly $51 apart. If you've been told the refinance is the affordable choice, that's the whole advantage.

Now look at where the money goes over ten years.

Path one costs about $6,100 more out of pocket over the decade and leaves you owing about $102,700 less at the end of it. Interest is where the difference lives: roughly $96,600 less on path one, because $300,000 of the debt kept borrowing money at 3.25% instead of 6.5%. Money borrowed versus money repaid is the frame I'd hold onto here. The two paths borrow the same $450,000. One of them repays far less for it.

The gap keeps widening after year ten. The home equity loan pays off in year 15, and your payment drops back to about $1,462 for the rest of the first mortgage. The cash-out refinance keeps collecting $2,844 a month for the full 30 years, and part of that difference comes from the longer term.

The Blended-Rate Rule That Decides

The screen I'd run first takes a pencil and two minutes. Weight each balance by its rate. In the example, $300,000 at 3.25% is $9,750 a year in interest, $150,000 at 8% is $12,000, and together that's $21,750 on $450,000, a blended rate of about 4.83%. Compare that blend to the cash-out quote. If the blend is lower, keep the first mortgage, fund the payout with the second lien, and solve your ex's liability separately. In this example the refinance would need to come in near 4.8% to break even on interest, and with the Freddie Mac average at 6.76%, that's a long way from where the market sits.

Part of my job at AmeriSave has been helping build the pricing logic that compares first and second mortgage structures against a borrower's full debt picture and surfaces the one that saves the most each month. The blended-rate screen is the pencil-and-paper version of the same idea, and it's honest in both directions. Swap in a 6% first mortgage on the same balances and the blend comes to 6.67%. Now a 6.5% cash-out beats it, and it cleans up the note in the same closing.

A few refinements, because pure rules leave out the cases that decide real files.

The blended rate ignores term. The 15-year home equity loan in my example produces the higher combined payment. If payment shock is your binding constraint, stretching the same $150,000 to 20 years at 8% drops it to about $1,255 a month, for a combined payment near $2,717, below the refinance. Ten-year interest rises to roughly $187,500, still about $85,000 less than the cash-out. You trade some interest for breathing room, and the trade is yours to make.

A $30,000 payout against a $600,000 first is almost always a second lien, because the higher rate applies to a small share of the debt and the blend barely moves. The smaller the buyout is relative to the first mortgage, the more clearly the second lien tends to win. As the buyout grows toward the size of the first, the 8% carries more weight and the blend drifts up.

Liability can override all of it. If a release isn't available and the decree requires your ex off the note by a date, a refinance may be the only path that meets the deadline.

One more item, on the tax side. The IRS, in Publication 936, limits the home mortgage interest deduction to loan proceeds used to buy, build, or substantially improve the home that secures the loan. Whether paying a former spouse for their share of the house meets that test is a question for your tax advisor, and I'd run the comparison above pre-tax rather than assuming a deduction on either path.

What the Processing Desk Will Ask You For

Whichever path you choose, the file looks similar from my side. We'll want the complete decree and settlement agreement, every page, because the underwriter reads the property section for the buyout terms and the support section for anything that changes your income or your obligations. We'll want the deed transferring title, or the decree language ordering it. If you're going the limited cash-out route, we'll document that you both owned the home for the 12 months Fannie Mae requires. And we'll qualify you on your income alone. If you'll receive support payments and want them counted, expect to document that they're being paid and will continue. If you'll pay support, it counts against you as an obligation.

The appraisal is the moment the file can turn. If value comes in under what the settlement assumed, the equity split, the buyout number, and the second-lien limit can all move at once. This is where the relationship with your loan officer earns its keep. When bad news arrives mid-process, you want to have already been working the problem with someone in your corner, so you can hear the options rather than brace against them. On my team at AmeriSave we name the milestones as they land, because a divorce buyout is a hard season and the wins along the way deserve to be noticed.

The Bottom Line

Separate the three problems before you pick a loan. The money for your ex, the title, and the note each have their own solution, and only the refinance forces you to solve all three with one expensive tool. If your first mortgage carries a rate the market no longer offers, run the blended-rate screen. When the blend of your first and a second lien beats the cash-out quote, keep the first, fund the payout with a home equity loan, and take your ex's liability to the servicer as a separate question. When your first is already near market, or the calendar and the servicer leave you no room, the refinance is the right tool, and the limited cash-out treatment is worth asking for by name.

Whatever you choose, the option that checks both boxes, the least money repaid over time and the smallest jump in your monthly obligation, is usually the one that fits.
