What Is an Assumable Mortgage and How Does It Work?

By Jerry L Kindig III, NMLS #2397823

Buyers ask me this all the time: "The seller has a low rate from a few years ago. Can I just take over their loan?" Sometimes, yes. That's called an assumable mortgage, and with rates higher than they were a few years back, more buyers are asking about it.

It can be a great deal in the right situation. It also comes with a catch that surprises a lot of people. Here's how it works in plain English.

What is an assumable mortgage?

An assumable mortgage is a home loan that a buyer can take over from the seller. Instead of getting a brand new loan, you step into the seller's existing one: the same interest rate, the same remaining balance, and the same time left on the loan.

So if the seller locked in a lower rate years ago, that rate can come with the house. You're not getting a new rate at today's pricing. You're picking up where the seller left off, and you agree to make all the future payments as if the loan had been yours from the start.

Which loans are assumable?

Not every mortgage can be assumed. Here's the general rule of thumb:

• FHA loans. HUD's guidelines say FHA-insured mortgages are assumable. For loans made after the late 1980s, the buyer has to be reviewed for credit and generally has to plan to live in the home.
• VA loans. VA loans are assumable, and per the VA Buyer's Guide, the buyer doesn't have to be a veteran. The loan has to be current and the buyer has to meet VA's credit and income standards.
• USDA loans. These can be assumed with USDA's approval, but the buyer has to meet program rules, and many USDA assumptions come with new rates and terms rather than the seller's original ones.
• Conventional loans. Most have a "due-on-sale" clause, which means the loan has to be paid off when the home sells. So in most cases a buyer can't assume a conventional loan. There are limited exceptions, like certain family transfers, so it's worth asking the servicer.

The easiest way to know for sure: ask the seller what type of loan they have, then have their servicer confirm whether it's assumable.

The catch: you have to cover the seller's equity

This is the part that trips people up. When you assume a loan, you only take over what the seller still owes. The difference between the price and that balance is the seller's equity, and you have to cover it.

Say a home is priced well above what's left on the seller's loan. That gap is cash you'd bring to closing, or money you'd need to borrow some other way. For homes bought or refinanced recently, the gap may be small. For a seller who's owned for years and built up a lot of equity, it can be a big number.

Some buyers cover the gap with savings. Some use a second loan, where the program and the lender allow it. Either way, the low rate only applies to the part of the price you assume, not the whole thing.

How the assumption process works

An assumption goes through the seller's servicer, not a lender you pick. Here's the general flow:

1. Confirm the loan is assumable. The seller's servicer can tell you, and the listing agent can help track this down.
2. Write the offer with the assumption in mind. Your contract should say you plan to assume the loan and how you'll cover the equity gap.
3. Apply with the servicer. You'll send pay stubs, tax returns, bank statements, and the usual paperwork. Here's a list of documents lenders typically ask for.
4. Get approved and close. The servicer reviews your credit and income. If you're approved, you close and the loan moves into your name.

Timing matters. VA's own rules give servicers with automatic authority 45 days to decide on a complete assumption package, and HUD's FHA guidance also uses a 45-day window once the servicer has all the documents. Build extra time into your contract either way.

What it costs to assume a mortgage

Assumption fees can be lower than the costs of a new loan, but they aren't free. A few things to know:

• FHA lets servicers charge an assumption processing fee of up to $1,800, per a 2024 HUD update.
• VA charges a funding fee of 0.5% on assumptions, unless the buyer is exempt.
• You'll still have normal closing costs like title and recording fees.

What sellers with VA loans should know

If you're a veteran selling your home, this matters to you. When a non-veteran assumes your VA loan, your VA entitlement stays tied to that loan until it's paid off. That can limit your ability to use your VA benefit on your next home.

There's a way around it. If the buyer is an eligible veteran with enough entitlement, they can substitute theirs for yours, and your entitlement can be restored. If you're comparing VA with other options, our FHA vs. VA comparison lays out the differences.

Is assuming a mortgage worth it?

It can be, if three things line up:

• The seller's rate is meaningfully better than what you'd get on a new loan today.
• The equity gap is something you can realistically cover.
• You qualify with the servicer and can live with a slower, less flexible process.

If the gap is huge or you'd need expensive financing to cover it, a regular new loan might work out better. That's why I like to run both side by side. And if you're weighing whether to buy at all right now, here's my take on whether to wait for rates to drop.

FAQ

Can anyone assume an FHA or VA loan?
Not just anyone. The buyer has to be approved by the servicer, which looks at credit and income. For VA loans, the buyer doesn't have to be a veteran, but they still have to qualify.

Do I need a down payment to assume a mortgage?
You won't make a typical down payment, but you do need to cover the difference between the price and the loan balance. That's often a bigger number than a normal down payment.

Can I assume a conventional loan?
Usually not. Most conventional loans have a due-on-sale clause. There are a few exceptions, so it's worth asking the servicer.

Is the seller still responsible after an assumption?
That depends on whether the servicer formally releases the seller from liability. Sellers should ask for a release in writing as part of the deal.
