Mortgage Recast vs. Refinance: How to Lower Your Payment and Keep Your Rate

Picture this. You found the right house in St. Johns County. Maybe it's a new build. You couldn't wait for your current home to sell, so you bought first and put down what you could.

Three months later your old house closes. Now you're holding a big check from the sale. And you're looking at a bigger mortgage payment than you want.

You have three choices. Keep the cash. Refinance. Or recast.

I'm Jason Kindler. I've been originating mortgages since 2001, and I'm the President of First Coast Mortgage Funding in Jacksonville. I get this question a lot from move-up buyers. Here's how a recast works, when it beats a refinance, and the Florida detail most articles skip.

What is a mortgage recast?

A recast, sometimes called re-amortization, has two steps.

1. You send your servicer a large extra payment that goes straight to principal.
2. You ask the servicer to recalculate your monthly principal and interest on the lower balance.

That's it. You keep the same loan. You keep the same interest rate. You keep the same maturity date. Fannie Mae's servicing rules describe it this way: the new payment is based on the current unpaid balance, the current interest rate and the remaining term, and only principal and interest change. Fannie Mae also says a re-amortization is not treated as a loan modification.

Here's the simple math. Your principal and interest payment moves in step with your balance. If a lump sum cuts your balance by 20%, your principal and interest payment drops by about 20%. Same rate. Same end date. Smaller payment.

Mortgage recast vs. refinance: what's the difference?

The big idea: a recast changes your balance. A refinance changes your loan.

If you like your rate, a refinance trades it away. A recast lets you keep it and still lower your payment. If you'd get a better rate today than the one you have, a refinance may make more sense. A recast can't touch your rate. You can read more about how a rate and term refinance works on my site.

The Florida detail most recast articles miss

Most Florida homeowners have an escrow account. That means your monthly payment covers four things: principal, interest, property taxes and homeowners insurance. Some homes add flood insurance too.

A recast only lowers the principal and interest part.

Your property tax bill doesn't care about your loan balance. Neither does your insurance company. So if taxes and insurance are a big share of your payment, the drop from a recast will feel smaller than you expect. Your escrow can also still go up or down at your yearly escrow review.

Before you send a big check, pull up your last mortgage statement. Look at how much of your payment is principal and interest and how much is escrow. That tells you what a recast can actually move.

Can you recast an FHA, VA or USDA loan?

Usually not. Here's why.

Most FHA, VA and USDA loans are packaged into Ginnie Mae securities. Ginnie Mae's guide says each loan must be repaid in equal monthly installments over its fixed term, and "no loan may be re-amortized while it is in a pool." Several large servicers say plainly on their websites that FHA, VA and USDA loans aren't eligible for their recast programs.

VA's own rules do allow re-amortization after a partial prepayment if the loan holder agrees in writing. But if your VA loan sits in a Ginnie Mae pool, the pool rule wins. So the answer for most VA borrowers is no.

What you can still do with a government loan:

• Pay extra principal anyway. You'll save interest and pay off sooner. Your monthly payment just won't drop.
• Refinance into a conventional loan once you have enough equity, if the numbers work. Some FHA borrowers do this partly to drop mortgage insurance.
• Look at a VA streamline refinance if you're a VA borrower and rates have moved in your favor. See my VA loan page for the basics.

Conventional loans are the main recast candidates. Both Fannie Mae and Freddie Mac allow servicers to re-amortize after a large principal payment. Freddie Mac's guide says the payment must be current, the maturity date can't be extended and the note rate stays the same. Even then, a recast is done at your servicer's discretion. Not every servicer offers it.

The move-up buyer play: buy first, sell, then recast

This is where a recast really earns its keep.

A lot of my clients in Jacksonville, St. Johns and Clay County are second or third-time buyers. They want the new house before they sell the old one. Nobody wants to move twice. And builders don't always wait for your sale to close.

Here's the sequence I walk people through:

1. Buy the new home first with a conventional loan. You may use savings, a bridge loan or a home equity line on your current house to cover the down payment.
2. Sell your current home. Pay off any bridge loan or equity line.
3. Send the leftover sale proceeds to your new loan as a principal payment.
4. Ask your servicer to recast. Your monthly payment comes down to match the smaller balance.

You keep the rate you locked when you bought. You don't pay for a second closing. And you didn't have to wait to sell before you could buy.

One planning tip. If you think you'll want to recast later, tell your loan officer up front. It's one reason to choose a conventional loan over a government loan when you qualify for both. Your loan will likely be serviced by someone else after closing, so recast rules can vary. But starting with a loan type that can be recast keeps the door open.

Recast vs. extra payments vs. keeping your cash

A recast isn't the only thing you can do with a lump sum. Here's how the options compare.

Recast. Lower monthly payment. Same rate and payoff date. Your total interest goes down because your balance is smaller. Good if monthly cash flow matters most.

Extra principal, no recast. Your payment stays the same. But you pay the loan off sooner and save interest. Good if you're happy with your payment and want to be debt-free faster.

Keep the cash. Your money stays liquid for emergencies, a new roof or hurricane prep. In Florida, that cushion matters. Once money goes into your house, you'd need to sell, refinance or borrow against it to get it back.

There's no single right answer. It depends on your rate, your savings, your plans for the house and how long you'll stay. I'd rather you make this call with your full picture in front of you.

Can a lump sum help you drop PMI?

It can, but the recast itself isn't what does it.

Under federal law, you can ask your servicer in writing to cancel private mortgage insurance once your balance reaches 80% of your home's original value. The CFPB says you can ask early if extra payments got you there. You need a good payment history, no second liens and proof your home's value hasn't dropped. PMI also ends automatically when your balance is scheduled to hit 78%.

So if a lump sum gets you to that 80% mark, ask about PMI removal at the same time you ask about the recast. That's two savings from one check. FHA and VA loans follow different rules, so check with your servicer.

How to request a recast: questions to ask your servicer

Call the number on your mortgage statement. Then ask:

1. Do you offer recasts on my loan?
2. Is there a minimum lump sum?
3. Is there a processing fee?
4. Does my payment need to be current? Is there a waiting period after closing?
5. Do I send the lump sum first, or apply for the recast first?
6. How long until my new payment starts?
7. Will you send me the new payment in writing?

Get the answers in writing before you send any money. Recast rules are set by your servicer, and they vary.
