2-1 Buydown on Your Loan Estimate: What Austin Buyers See
Freddie Mac put the average 30-year fixed rate at 6.95 percent for the week ending September 17, 2026, and Austin is sitting in a buyer’s market: the Unlock MLS and Austin Board of Realtors August 2026 report showed a regional median sales price of $412,000, down 6.4 percent from a year earlier. In that combination, sellers and builders around Austin are handing out temporary buydowns to move houses. Then the buyer opens the Loan Estimate, looks for the lower payment they were promised, and finds the full rate staring back at them. Nothing went wrong. The paperwork is built that way on purpose, and knowing which document carries the buydown saves a lot of closing-week panic.
Key points:
- A temporary buydown almost never changes your mortgage note. Fannie Mae requires that the loan documents “reflect the permanent payment terms rather than the terms of the buydown plan.”
- Because of that, your Loan Estimate shows the note rate and the full payment, and the buydown is missing from the Projected Payments table.
- The buydown lives in a separate written agreement between whoever funds it and you, plus an escrow or custodial account that releases money each month.
- Underwriting uses the note rate, so a buydown does not raise your approval amount on conventional or FHA financing.
- On a $412,000 Austin purchase with 5 percent down, a 2-1 buydown deposit runs roughly $9,100 in this example, funded by the seller, builder, or lender.
- FHA rules on leftover buydown money differ from conventional rules, and the difference matters if you sell or refinance early.
Why does your Loan Estimate still show the full interest rate?
Because the buydown is usually not part of the loan contract. Under the official commentary to Regulation Z, when a third-party buydown “is not reflected in the credit contract between the consumer and the bank and the consumer is legally bound to the [note] rate from the outset,” the disclosures “must not reflect the seller buydown in any way.” The annual percentage rate and the projected payments are calculated on the rate written in your note, not the discounted rate you will actually pay in year one.
Fannie Mae’s Selling Guide reaches the same result from the other direction. Its temporary buydown rules (B2-1.4-04, updated August 7, 2024) require that “the mortgage instruments must reflect the permanent payment terms rather than the terms of the buydown plan,” and add that “in no event may the buydown plan change the terms of the mortgage note.”
There is an exception worth knowing. If a buydown is written into the credit contract itself, or if you pay for it yourself, Regulation Z requires a composite annual percentage rate and disclosures that show both payment levels. That structure is rarer in Austin purchase deals than the standard seller-funded agreement, so ask your loan officer which version you have rather than assuming.
| Document | What it says about your buydown |
|---|---|
| Loan Estimate, Loan Terms box | The note rate only. On the example below, 6.95 percent, never 4.95 percent. |
| Loan Estimate, Projected Payments | The full principal and interest payment for all 30 years, with no step-up schedule. |
| Closing Disclosure, Summaries of Transactions | The money itself, shown as a credit from the seller. |
| Buydown agreement | The actual year-by-year rates, the deposit amount, and who funded it. |
| Promissory note | The permanent terms. This is the obligation you sign. |
The buydown agreement is a separate contract
Fannie Mae requires that “the buydown plan must be a written agreement between the party providing the buydown funds and the borrower,” and that all of its terms be disclosed to Fannie Mae, the mortgage insurer, and the appraiser. FHA treats it the same way: the buydown agreement is one of the documents in the insured case binder, listed separately from the note and the Loan Estimate.
The money does not sit with your lender’s operating cash either. Fannie Mae requires buydown accounts to be “established and fully funded” before the loan is delivered and deposited “into custodial bank accounts,” specifically noting that buydown funds “cannot be included in accounts with the lender’s other corporate funds.” FHA’s version, in Handbook 4000.1, says flatly that “the Mortgagee must establish an escrow for temporary interest rate buydowns.”
Each month the escrow releases the difference between what you pay and what the note requires. Here is what that looks like on a $412,000 Austin purchase with 5 percent down, a $391,400 loan, and a 6.95 percent note rate, principal and interest only.
- Note rate payment: $2,590.86 a month.
- Year one at 4.95 percent: $2,089.18, about $502 a month lower.
- Year two at 5.95 percent: $2,334.07, about $257 a month lower.
- Total deposited into the buydown account: roughly $9,102, about 2.2 percent of the price.
That $9,102 is the number to look for in the seller credit on your Closing Disclosure. It is illustrative, not a quote, and it moves with the loan amount and the rate. When the seller funds it, the deposit counts against the interested-party contribution limits for your loan type, so it competes with any other closing costs you asked the seller to cover. Our comparison of 2-1 buydowns and discount points walks through how to split a fixed concession between the two.
Does the buydown change what you can qualify for?
No, and both rulebooks are explicit. Fannie Mae instructs that “the lender must qualify the borrower based on the note rate without consideration of the bought-down rate.” HUD Handbook 4000.1 says “the Mortgagee must use the Note rate when calculating principal and interest” on FHA loans with a temporary buydown.
So the debt-to-income ratio behind your approval is built on $2,590.86 in the example above, not $2,089.18. A buydown buys breathing room in the early years. It does not stretch your purchase price, which is one reason the underwriter never looks at the buydown agreement when sizing your loan.
What happens if the buydown money runs out or servicing transfers?
You still owe the full payment. Fannie Mae requires the agreement to state “that the borrower is not relieved of the obligation to make the mortgage payments required by the terms of the mortgage note if, for any reason, the buydown funds are not available.” FHA puts the same duty on the borrower: “if escrow payments are not received for any reason, the Borrower is responsible for making the total payment as described in the mortgage Note.”
Loan servicing changes hands often, and a buydown does not evaporate when it does. Where the lender funded the buydown, Fannie Mae requires the agreement to force the account balance to move with the file, so “the funds in the buydown account be transferred to the new servicer if the mortgage is included as part of a subsequent transfer of servicing.” Keep your copy of the buydown agreement and the first statement from any new servicer, then confirm the billed amount matches the year you are in. At Mortgage Austin we tell buyers to check that first post-transfer statement line by line, since a mismatch is easier to fix in month two than in month ten.
Which Austin transactions can even use one?
Temporary buydowns are narrower than most buyers expect. On the conventional side, Fannie Mae allows them on principal residences and second homes, and treats investment properties and cash-out refinances as ineligible, with restrictions on adjustable-rate plans. The rate reduction may not exceed 3 percent, the buydown period may not run longer than three years, and the borrower’s rate may not rise by more than 1 percent in any one-year interval.
FHA is tighter still. Handbook 4000.1 states that “temporary interest rate buydowns are not permitted with refinance transactions” and “are not permitted with ARM transactions.” That rules out the common idea of buying down the first year of an FHA refinance. If you are weighing a refinance instead, current pricing sits on our Austin mortgage rates page, and the loan options overview lays out which programs allow what.
Who keeps the leftover money if you sell or refinance early?
This is where conventional and FHA split, and it is worth a question before you sign. Fannie Mae’s disposition rules say that when the mortgage is paid in full, the remaining funds “should be credited to the total amount required to pay off the mortgage, or they may be returned to either the borrower or the lender as specified in the buydown agreement.” Your agreement decides, so read that clause.
FHA writes the answer into the escrow agreement itself. It must not “permit reversion of undistributed escrow funds to the provider if the Property is sold or the Mortgage is prepaid in full,” and it must not “allow unexpended escrow funds to be provided to the Borrower in cash, unless the borrower funds were used to establish the escrow account.” A seller who funds an FHA buydown cannot claw the balance back if you refinance in month 14.
Frequently Asked Questions
Why doesn’t my buydown show up on my Loan Estimate?
Because a standard seller-funded buydown sits outside the loan contract. Regulation Z commentary says that when a third-party buydown is not reflected in the credit contract, the disclosures must not reflect it in any way. Your Loan Estimate shows the note rate, the full payment, and an APR calculated on the permanent terms.
Is the buydown written into my mortgage note?
Almost never. Fannie Mae requires the mortgage instruments to reflect the permanent payment terms rather than the buydown plan, and states that the plan may not change the terms of the note. The buydown lives in its own written agreement between you and whoever funded it.
Who holds the buydown money after closing?
An escrow or custodial account, not your lender’s general funds. Fannie Mae requires buydown accounts to be fully funded before delivery and held in custodial bank accounts. FHA requires the mortgagee to establish an escrow. The account releases the monthly difference to the servicer on your behalf.
What happens to my buydown if my loan is sold to a new servicer?
The account travels with the loan. For lender-funded buydowns, Fannie Mae requires the agreement to provide that the funds transfer to the new servicer on a servicing transfer. Compare your first statement from the new servicer against your buydown agreement to confirm the billed payment matches the correct year.
Can I get a temporary buydown on an FHA refinance?
No. HUD Handbook 4000.1 states that temporary interest rate buydowns are not permitted with FHA refinance transactions, and they are also not permitted with FHA adjustable-rate mortgages. Conventional rules likewise treat cash-out refinances and investment properties as ineligible for temporary buydowns.
What if the escrow payment does not reach my servicer one month?
You owe the full note payment. Fannie Mae requires the buydown agreement to say the borrower is not relieved of the obligation if buydown funds are unavailable, and FHA says the borrower is responsible for the total payment described in the note. Call the servicer immediately and keep your buydown agreement handy.
If a seller or builder in the Austin area has offered to buy down your rate and the paperwork does not look like what you were told, that is a normal question to ask before you sign.
