The listing says:

**“Seller will buy your rate down!”**

Sounds great.

But here's the question I want you asking:

**What will my payment be when the buydown ends?**

With a common **2-1 temporary buydown**, the payment is calculated as though the interest rate were 2 percentage points lower during year one and 1 percentage point lower during year two.

Then year three arrives.

**The temporary discount is gone.**

Your mortgage doesn't suddenly become more expensive than originally agreed. You're simply moving to the payment based on the actual note rate you had from the beginning.

### A 2-1 Buydown Does Not Permanently Change Your Note Rate

This is the part buyers can misunderstand.

Suppose your mortgage has a **6.5% note rate**.

With a 2-1 temporary buydown, the payment could be calculated approximately like this:

**Year 1: 4.5% payment**

**Year 2: 5.5% payment**

**Year 3 and beyond: 6.5% payment**

The loan itself didn't start at 4.5%.

**6.5% was the note rate all along.**

Funds placed into a buydown account are used to subsidize the difference between the reduced payment you make during the temporary period and the payment required by the note.

### So Who Pays for the Buydown?

A temporary buydown isn't free money.

Someone funds it.

Depending on the loan and transaction, that may be the seller, builder or another permitted party.

When a seller is funding it, the cost generally comes from the [concessions negotiated as part of the transaction](https://voce.com/@jenniferchicano/denver-seller-concessions-help-pay-closing-costs-7xeog4) and must comply with the applicable mortgage-program requirements.

That's why **“seller-paid rate buydown”** isn't enough information for me.

I want to know:

**How much is the seller contributing, and what are we doing with those dollars?**

### Could the Seller's Money Be Used Differently?

Potentially.

Seller concessions may be able to help with eligible closing costs or other permitted expenses, subject to the loan program and transaction.

So if a seller is offering you thousands of dollars, there may be more than one way to structure those funds.

A temporary buydown could be useful if lowering the payment during the first year or two solves a specific problem for you.

But maybe reducing cash needed at closing matters more.

Or perhaps [another permitted financing structure deserves to be compared](https://voce.com/@jenniferchicano/denver-mortgage-rate-buydown-break-even-meu7ai).

**Don't choose the words “rate buydown.” Choose the numbers.**

### What If Rates Fall and I Refinance?

Maybe you will.

Maybe you won't.

[Future mortgage rates aren't guaranteed](https://voce.com/@jenniferchicano/denver-buying-home-2026-waiting-rates-mze7jk), and neither is your ability to refinance.

That's why I don't want a temporary buydown justified with:

**“Don't worry. You'll refinance before the payment goes up.”**

That makes the strategy depend on something we don't control.

A better question is:

**“Am I comfortable with the full payment if I never refinance?”**

If the answer is yes, then the temporary savings can be evaluated for what they actually are: **temporary savings.**

### Before You Say Yes to a 2-1 Buydown

Know these numbers:

**Your actual note rate**

**Your year-one payment**

**Your year-two payment**

**Your full payment beginning in year three**

**The total cost of the temporary buydown**

**Who is funding it**

**What other permitted uses of those dollars may be available**

Now you're comparing an actual financing strategy instead of reacting to a lower advertised payment.

### The Better Question

Don't ask only:

**“How low can the seller get my rate?”**

Ask:

**“What's the best use of the seller's dollars for my specific transaction?”**

Sometimes a temporary buydown may fit.

Sometimes another use of the concession may fit better.

**The important part is knowing what happens when the temporary discount ends before you agree to the structure.**

If a seller is offering concessions on a home you're considering, I can help you compare how different permitted structures affect your payment and cash needed at closing.
