If you're buying a home, you've probably heard a Realtor or lender say, “Let's ask the seller for a rate buydown.”

But what does a mortgage rate buydown actually mean?

Simply put, a mortgage rate buydown is a way to reduce the interest rate or initial monthly payment on your home loan by paying money upfront. In some real estate transactions, we can negotiate for the seller to provide a credit that can be applied toward eligible closing costs, including the cost of buying down the buyer's mortgage rate when permitted by the loan program.

This can be a powerful negotiating tool because instead of only focusing on getting the seller to lower the purchase price, we can look at whether using some of that negotiating power toward the buyer's interest rate could make a bigger difference in the monthly payment.

How Does a Mortgage Rate Buydown Work?

Let's use a simple example.

Imagine mortgage rates are around 6.5% when you're ready to purchase a home.

Instead of automatically accepting the 6.5% rate, we can sit down with your lender and ask:

“What would it cost to get this buyer's interest rate down to 5.5%?”

Your lender will calculate the cost based on your specific loan, loan amount, credit profile, mortgage program and current rate pricing.

For example, if the lender determines that it would cost $15,000 to obtain the lower rate, we may structure the offer to request a $15,000 seller credit toward the buyer's allowable closing costs, with the lender determining how much can actually be applied toward discount points for the rate buydown.

If negotiated successfully and permitted under the buyer's loan program, that seller credit can help cover the upfront cost associated with obtaining the lower mortgage rate.

The result can be a lower monthly principal-and-interest payment for the buyer.

Important: Going from 6.5% to 5.5% is only an example. There is no set formula saying a certain dollar amount will reduce a mortgage rate by a certain percentage. Mortgage pricing changes constantly, so your lender must calculate the actual cost.

What Are Mortgage Discount Points?

A permanent mortgage rate buydown commonly involves paying discount points.

Discount points are upfront fees paid to the lender in exchange for a lower mortgage interest rate.

One discount point equals 1% of the loan amount.

For example:

On a $700,000 loan, one point equals $7,000.

That does not mean paying $7,000 will automatically lower your interest rate by 1%. The amount that each point reduces the rate depends on the lender, loan program and current mortgage market.

This is why I always recommend having the lender run the actual numbers before deciding how much seller credit we should request.

Why Would We Ask for a Seller Credit Instead of a Lower Price?

This is where rate buydowns can become particularly interesting during negotiations.

Many buyers automatically think:

“I want $20,000 off the price.”

But lowering the purchase price by $20,000 doesn't necessarily lower the monthly mortgage payment as much as buyers expect.

Depending on the loan and current mortgage pricing, using some or all of that negotiating power toward allowable closing costs and a rate buydown could potentially create a larger reduction in the buyer's monthly payment.

For example, instead of simply writing an offer $20,000 below asking price, we might compare:

Option A: Negotiate a lower purchase price.

Option B: Negotiate a seller credit and use eligible funds toward reducing the interest rate.

Then we have the lender calculate the monthly payment and upfront costs under both scenarios.

The numbers tell us which structure makes more sense for that particular buyer.

How Much Can a Rate Buydown Lower Your Monthly Payment?

It depends on the loan amount and the difference between the interest rates.

On larger mortgages, even a relatively small change in the interest rate can make a noticeable difference in the monthly principal-and-interest payment.

This is why buyers shouldn't only ask:

“What's the price of the house?”

They should also ask:

“What will my actual monthly payment be?”

Purchase price, down payment, interest rate, property taxes, HOA dues, Mello-Roos or special assessments, homeowners insurance and mortgage insurance can all affect the total monthly housing expense.

When I'm helping a buyer compare homes, I want them looking at the whole financial picture, not just the list price.

What Is a Permanent Rate Buydown?

A permanent rate buydown lowers the interest rate for the life of that particular mortgage.

For example, if a buyer qualifies for a 30-year fixed mortgage and uses discount points to obtain a lower fixed rate, that lower interest rate applies according to the terms of the loan rather than automatically increasing after one or two years.

This is different from a temporary rate buydown.

What Is a 2-1 Rate Buydown?

A 2-1 buydown is a common type of temporary mortgage buydown.

Instead of permanently changing the note rate, funds are used to subsidize a portion of the buyer's mortgage payments during the first two years.

A simplified example could look like this if the note rate were 6.5%:

Year 1: Payments are calculated as though the rate were 4.5%
Year 2: Payments are calculated as though the rate were 5.5%
Year 3 and beyond: Payments are based on the full 6.5% note rate

This can provide significant payment relief during the first couple of years of homeownership.

However, buyers need to understand that the payment will increase according to the predetermined schedule. Depending on the loan program, borrowers may also have to qualify based on the full note rate rather than the temporarily reduced payment.

Temporary vs. Permanent Rate Buydown

These two strategies solve different problems.

A permanent rate buydown may make sense when a buyer wants to secure a lower interest rate for as long as they keep that mortgage.

A temporary rate buydown may make sense when a buyer wants a lower payment during the first few years of homeownership.

The better structure depends on the buyer's finances, available seller credit, loan program, current mortgage pricing and how long the buyer expects to keep the mortgage.

Your lender should show you both options when available so you can compare them side by side.

What Happens If Mortgage Rates Drop Later?

This is an important question.

Buying down your interest rate today doesn't prevent you from potentially refinancing later if mortgage rates decrease and you qualify for a refinance.

However, refinancing is not free and future mortgage rates are never guaranteed.

That's also why buyers should consider how much they are spending upfront for a permanent rate buydown. If you pay a significant amount for discount points and refinance shortly afterward, you may not have held the original mortgage long enough for the monthly savings to outweigh the upfront cost.

Your lender can help calculate the break-even point.

What Is the Break-Even Point on a Rate Buydown?

The break-even point tells you approximately how long it takes for the monthly savings from a permanent rate buydown to recover the upfront cost.

Here's a simplified example:

If buying down your rate costs $10,000 and saves you $250 per month in principal and interest:

$10,000 ÷ $250 = 40 months

Your approximate break-even point would be 40 months, or about 3 years and 4 months.

If you're likely to sell or refinance before reaching that point, paying for the permanent buydown yourself may be less attractive.

However, the analysis can look different when the buydown is being funded through a negotiated seller credit that you otherwise would not receive.

Can Every Buyer Ask for a Seller Rate Buydown?

You can negotiate for seller concessions, but whether the seller agrees is another question.

The amount of seller contribution that can actually be used also depends on the loan program, down payment, occupancy, property type and applicable lending guidelines.

That's why the Realtor and lender should work together before the offer is written.

I want to know:

  • How much seller credit can this buyer receive?
  • How much of the credit can be used toward discount points?
  • What would different interest-rate options cost?
  • How would each option change the monthly payment?
  • Are there other closing costs that should be covered first?
  • Would a temporary or permanent buydown make more sense?

Then we can structure the offer around actual numbers instead of guessing.

Frequently Asked Questions About Mortgage Rate Buydowns

What does buying down an interest rate mean?

Buying down a mortgage interest rate generally means paying an upfront cost to obtain a lower interest rate or using funds to temporarily subsidize the mortgage payment. A permanent buydown typically involves discount points, while a temporary buydown reduces the effective payment for a specified initial period.

Can a seller pay for a mortgage rate buydown?

Yes, seller contributions can potentially be used toward eligible mortgage costs, including discount points or certain temporary buydown structures, subject to the specific loan program and contribution limits. Your lender should confirm how much seller credit is allowed before you write the offer.

Is a seller credit free money?

No. A seller credit is part of the overall real estate negotiation.

A seller may agree to contribute toward a buyer's eligible closing costs rather than accepting a lower purchase price, making repairs or agreeing to another concession. The amount and structure are negotiated as part of the transaction.

Does one discount point lower my rate by 1%?

No.

One discount point costs 1% of the loan amount, but it does not automatically reduce the interest rate by one percentage point.

How much your rate decreases depends on current mortgage pricing, your lender, loan type and other factors.

Is a rate buydown the same as getting a lower purchase price?

No. A purchase-price reduction lowers the amount you're paying for the property. A rate buydown addresses the financing cost or initial payment.

Depending on the numbers, one strategy may have a greater impact on your monthly payment than the other. This should be calculated for the specific transaction.

Is a 2-1 buydown permanent?

No. A 2-1 buydown is temporary.

The payment subsidy applies during the first two years. After that, the borrower makes payments based on the full note rate for the remaining loan term, assuming the loan hasn't been refinanced or paid off.

Can I refinance after using a rate buydown?

Potentially, yes. A rate buydown does not by itself prevent a future refinance. Refinancing depends on future interest rates, property value, credit, income, equity and lending requirements, and it generally comes with costs.

Is buying down a mortgage rate worth it?

It depends.

For a permanent buydown, consider the upfront cost, monthly savings, break-even point and how long you expect to keep the mortgage.

If you're negotiating with a seller who is willing to provide a credit, it can also be worth comparing a rate buydown with a price reduction or other concessions.

The best way to make that decision is to have your lender calculate multiple scenarios using the same purchase price and loan amount.

Buying a Home in Santa Clarita? Ask About a Rate Buydown

When I'm negotiating for a buyer, I'm not only looking at how much we can get off the purchase price. I'm looking at how we can structure the entire deal to benefit that buyer.

Sometimes that means negotiating the price.

Sometimes it means asking for closing costs.

Sometimes it means negotiating a seller credit toward a mortgage rate buydown.

And sometimes it means a combination of all three.

If you're considering buying a home in Santa Clarita, Valencia, Saugus, Canyon Country, Newhall, Stevenson Ranch or the surrounding Los Angeles area, we can sit down with your lender and compare the numbers before writing an offer.

Understanding your options can help you make an informed decision based not only on the price of the home, but also on what that home may actually cost you each month.
