Temporary vs. Permanent Mortgage Rate Buydowns: Which One Actually Saves You More Money?

When mortgage rates are higher than buyers would like, one phrase starts showing up everywhere: “We’ll buy down your rate.”

But there’s an important question buyers—and sellers—should ask next:

Are we talking about a temporary buydown or a permanent rate buydown?

They are not the same thing, and depending on how long a buyer expects to keep the mortgage, one strategy may provide significantly more value than the other.

As a mortgage professional, I often tell clients that the goal shouldn’t simply be to get the lowest advertised interest rate. The goal is to determine where the available money creates the greatest financial benefit.

What Is a Temporary Rate Buydown?

A temporary buydown reduces the effective payment the borrower makes during the first one, two, or sometimes three years of the mortgage. The actual note rate does not change.

One of the most common versions is a 2-1 buydown.

For example, if the note rate is 6.50%:

The difference between the borrower's reduced payment and the payment required by the note is funded upfront through the buydown account.

Depending on the loan program and transaction, those funds may be contributed by an eligible party such as the seller, builder or lender, subject to applicable program guidelines and contribution limits.

One important detail that sometimes surprises buyers: on many conventional loans, the borrower still qualifies using the full note rate—not the temporary reduced payment.

So a temporary buydown generally isn't a way to qualify for a larger mortgage. It's a way to make the first years of homeownership more affordable from a cash-flow standpoint.

What Is a Permanent Rate Buydown?

A permanent buydown works differently.

Instead of subsidizing the payment temporarily, discount points or other eligible funds are used to obtain a lower note interest rate for the life of the loan.

For example, a borrower might have the choice between a 6.50% rate with no discount points and a lower rate after paying points.

The exact cost and rate reduction cannot be assumed because mortgage pricing changes with the market and depends on the loan scenario.

The advantage is simple: the lower rate doesn't disappear after one or two years.

As long as the borrower keeps that mortgage, the borrower continues receiving the benefit.

Let's Look at an Example

Assume a buyer is obtaining a $400,000, 30-year fixed-rate mortgage at a 6.50% note rate.

The approximate principal-and-interest payment would be $2,528 per month.

With a 2-1 temporary buydown:

In this simplified example, approximately $9,104 would be used to subsidize the borrower's principal-and-interest payments during the first two years.

Now compare that with using funds toward a permanent rate buydown.

If, purely for illustration, the borrower were able to obtain a permanent 6.00% rate, the principal-and-interest payment would be approximately $2,398 per month.

That's about $130 per month less than the payment at 6.50%, and that savings could continue for as long as the borrower keeps the mortgage.

This example is for educational purposes only. It does not represent a current rate quote or guarantee that a specific amount of discount points will produce a particular interest rate.

So Which Buydown Is Better?

Here's where it gets interesting.

A temporary buydown may make more sense when:

The buyer wants maximum payment relief during the first year or two of homeownership.

This can be particularly helpful when a buyer expects income to increase, wants additional breathing room after paying moving expenses, or simply prefers to keep more monthly cash available after purchasing the home.

It may also be attractive when the seller is paying for the buydown.

There's another consideration: What if rates fall significantly in the next couple of years and refinancing eventually makes financial sense?

If a buyer spent substantial money personally to permanently buy down a mortgage rate and then refinanced shortly afterward, the buyer may not have held the original loan long enough to recover that upfront expense.

That's why I always want to calculate the break-even period before recommending that a borrower spend significant money on discount points.

A permanent buydown may make more sense when:

The buyer expects to keep the home and mortgage for a long time.

If the upfront cost can be recovered through the monthly savings within a reasonable period, everything after the break-even point can represent additional savings.

A permanent buydown can also provide something many homeowners value: certainty.

The borrower doesn't need rates to fall later for the strategy to work. The lower rate is already built into the mortgage.

What About the Seller? Which Is Better?

This is where rate buydowns can become a powerful real estate negotiation tool.

Suppose a seller is considering a $10,000 price reduction.

Depending on the buyer's financing, that $10,000 reduction in purchase price may result in a surprisingly small change in the buyer's monthly mortgage payment.

But if some or all of those funds can instead be structured as an eligible seller concession and used strategically toward financing costs or a rate buydown, the buyer may experience a much larger reduction in the monthly payment—particularly during the first years with a temporary buydown.

That can create a potential win-win:

The buyer: receives meaningful payment relief.

The seller: may be able to preserve more of the home's contract price rather than making a larger price reduction.

Of course, seller contributions are subject to loan-program guidelines and limits, so the financing strategy needs to be reviewed before the purchase agreement is finalized.

Temporary vs. Permanent Buydown at a Glance

Don't Automatically Choose the Lowest Rate

This is probably the most important takeaway.

The lowest mortgage rate isn't automatically the best financial decision.

If obtaining that rate costs thousands of dollars, we need to know how long it will take to recover that money.

Likewise, a temporary buydown isn't automatically better simply because the first-year payment looks fantastic.

The right questions are:

How much does each option cost? How much does each option save? Who is paying for it? How long do you realistically expect to keep this mortgage? And what is the break-even point?

Those answers can completely change the recommendation.

My Approach With Buyers

At ALCOVA Mortgage, I believe borrowers should be able to see the numbers before making the decision.

When I'm comparing a temporary buydown with a permanent rate buydown, I want my client to understand not just the rate, but the actual dollars involved—the upfront cost, monthly savings, cumulative savings and break-even period.

Sometimes the permanent buydown wins.

Sometimes the temporary buydown wins.

And sometimes the smartest decision is not buying down the rate at all and using those funds somewhere else in the transaction.

Mortgages aren't one-size-fits-all, and the best financing strategy should be built around the buyer's individual circumstances and plans.
