Seller tips

Rates are up. What is this rate buydown everyone keeps mentioning?

Lately, all we've been hearing about is rising mortgage rates. And yes, rates have gone up. But what does that actually mean if you're buying or selling a home?

For buyers, it means taking a closer look at your monthly payment and the options available to you. For sellers, it means paying attention to how buyers are responding to your listing and considering incentives that could help move the sale forward.

One option worth understanding is a seller paid mortgage rate buydown. Here's how it works, what it could cost, and what it could mean for your monthly payment.

The latest national average for a 30 year fixed mortgage is 7.40%, according to Freddie Mac's October 8, 2026 report; individual lender quotes vary.

What does that mean for the market?

We've seen this before: buyers and sellers both need time to adjust when rates rise. Buyers reassess what monthly payment works for them, while sellers need to respond to the activity and feedback their listings are getting.

What is a seller paid rate buydown?

A seller paid buydown uses a negotiated seller contribution at closing to help reduce the buyer's mortgage payment. It is part of the purchase agreement, and the lender must approve the structure and the amount.

There are two main approaches: a temporary buydown and a permanent buydown. They work differently, so it matters which one you are discussing.

What Would a Rate Buydown Look Like on a $2 Million Bay Area Home?

Let's say you're buying a $2 million home in the Bay Area. For each comparison, we'll use 20% down ($400,000), and a $1.6 million mortgage over 30 years at a hypothetical 7.5% fixed rate. The full principal and interest payment is approximately $11,187 per month. This rate is illustrative, not a lender quote.

Payments below exclude taxes, homeowners insurance, HOA dues and any mortgage insurance. Figures are rounded; subsidy totals use unrounded payments.

First: how a 3-2-1 buydown works

A 3-2-1 buydown reduces the buyer's payments for three years. Payments are calculated at three percentage points below the mortgage rate in year one, two points below in year two, and one point below in year three. The full payment starts in year four.

The actual fixed mortgage rate stays at 7.5%. A seller funded account covers the difference between the buyer's reduced payments and the full payments due.

What would the seller pay?

The estimated subsidy is $75,091, approximately 3.75% of the purchase price. That covers about $36,966 in year one, $25,234 in year two and $12,892 in year three. The total is calculated before rounding each year's amount.

The seller funds the agreed contribution through closing rather than making monthly payments afterward. Separate lender or program fees, if any, would be additional. The lender must approve the program and seller credit.

Next: how a 2-1 buydown works

A 2-1 buydown follows the same approach for two years. Payments are calculated at two percentage points below the mortgage rate in year one and one point below in year two. The full payment begins in year three.

What would the seller pay?

The estimated subsidy is $38,126, approximately 1.91% of the purchase price, excluding separate program fees. It covers about $25,234 in year one relief and $12,892 in year two relief.

That is approximately $36,966 less than the 3-2-1, but the full payment starts a year sooner.

For either temporary option, the buyer must qualify at the full mortgage rate and be comfortable with the full payment. Here, that means about $11,187 in monthly principal and interest plus the other ownership costs. The subsidy creates breathing room; it should not be the only reason the home fits your budget.

Finally: how a permanent rate buydown works

A permanent buydown uses discount points paid at closing to lower the actual mortgage rate for as long as you keep the loan. You can negotiate a seller credit to pay those points, subject to lender approval. The rate does not step back up after two or three years.

What would it cost?

One point costs 1% of the loan amount. On our $1.6 million mortgage:

These are points costs, not total closing costs. There is no fixed rate reduction per point. The reduction depends on the lender, loan program and market that day. A permanent buydown needs an actual quote for the rate and points.

For illustration only, suppose a lender offered a reduction from 7.5% to 7.0% for two points. This is assumed pricing, not a lender quote or a claim that two points will buy that reduction.

The points would cost $32,000. Monthly principal and interest would fall from approximately $11,187 to $10,645, saving about $543 per month for as long as the buyer keeps that mortgage.

Dividing the points cost by the monthly payment savings gives a simple payback comparison of about 59 months, or just under five years. This cash flow comparison does not account for remaining principal, the time value of money or other fees. Selling or refinancing sooner changes the long term benefit.

Comparing the upfront costs

Temporary costs are calculated subsidies for our hypothetical 7.5% mortgage. The permanent figure is an assumed two point cost, not verified pricing for a particular rate. All exclude other closing costs and separate program fees.

Ask your lender to compare these options using the same underlying loan, including any differences in the base rate or fees. A 3-2-1 provides more early relief, a 2-1 requires a smaller contribution, and a permanent buydown can provide ongoing savings.

Why ask for a buydown instead of a price reduction?

A lower purchase price has lasting value. It reduces what you pay for the home and, depending on your financing, how much you borrow. But a temporary buydown may create a much larger payment reduction during the first two years.

For example, reducing the price above by $40,000, while keeping a 20% down payment, would reduce the loan by $32,000. At the same hypothetical 7.5% rate, that lowers monthly principal and interest by about $224 for the life of the loan. It also reduces the down payment by $8,000.

Compare that with approximately $2,103 per month in first year relief from the 2-1 buydown. The seller's cost is similar in these examples, but the buyer receives the benefit differently.

Neither option is automatically better. Compare the total cost and long term payment, not just the first year savings.

Sellers: let your listing's activity guide the strategy

When rates rise, buyers are looking closely at monthly payments. If your home is getting showings but no offers, or very little activity at all, review the price, presentation, competing listings and buyer feedback with your agent.

A seller paid buydown may help address a payment concern. A price adjustment may be more useful if your asking price is keeping buyers from considering the property in the first place. Sometimes both deserve discussion.

The goal is to respond to the market your home is in today. An incentive still costs money, so compare your expected net proceeds under each option.

How do you ask for one?

Start with your lender before writing the offer. Confirm that your loan permits the buydown, get its actual cost and check the seller contribution limits. Those limits depend on the loan program, occupancy and down payment, and other seller credits can count toward them too.

Then your agent can negotiate a specific seller credit in the purchase agreement, subject to lender approval. The credit is not unrestricted cash handed to you; it must be used for approved costs.

And please do not build your budget around a guaranteed refinance. If rates fall and you qualify, refinancing may become an option. But that timing is uncertain, and refinancing has costs of its own.

If you are buying or selling in Fremont, Newark or elsewhere in the Bay Area, let's look at the numbers together. A price adjustment, seller credit or rate buydown can each serve a different purpose. The right strategy starts with understanding what actually helps you move forward.

How much does a 2-1 buydown cost on a $2 million home?

With 20% down, a $1.6 million loan and a hypothetical 7.5% rate, the 2-1 buydown subsidy is about $38,126, roughly 1.91% of the purchase price. It lowers the first year payment by about $2,103 a month.

How much does a 3-2-1 buydown cost on a $2 million home?

Using the same example, the 3-2-1 buydown subsidy is about $75,091, roughly 3.75% of the purchase price, covering three years of reduced payments.

Is a buydown better than a price reduction?

Neither is automatically better. In this example a $40,000 price cut lowers the payment about $224 a month for the life of the loan, while a 2-1 buydown at a similar cost lowers it about $2,103 a month in year one. Compare the total cost and long term payment.
