Mortgage Rate Buydowns in NJ: 2-1 and 3-2-1 Guide
See the payment schedule, understand where the subsidy comes from, and compare a temporary buydown with points, closing-cost credits, or a price reduction before you use valuable transaction dollars.
The note rate stays whole
A temporary buydown does not rewrite the full note rate. Scheduled funds make up the difference during the buydown period.
Qualification uses the full payment
Fannie Mae and VA guidance require qualifying without relying on the temporary payment reduction.
The agreement controls
Funding, payment steps, custodial handling, and unused funds belong in the written buydown agreement.

This calculator is for education and planning, not a Loan Estimate, commitment, approval, interest-rate offer, or disclosure. The actual buydown structure, funding amount, eligibility, payment, APR, fees, and treatment of unused funds are controlled by the lender, investor, loan program, written buydown agreement, and final transaction documents.
A transparent $500,000 example
This hypothetical uses a $500,000, 30-year fixed loan with a 7% full note rate. It shows principal and interest only. At the full note rate, estimated P&I is $3,326.51 per month.
| Period | 2-1 rate | 2-1 P&I | 3-2-1 rate | 3-2-1 P&I |
|---|---|---|---|---|
| Year 1 | 5% | $2,684 | 4% | $2,387 |
| Year 2 | 6% | $2,998 | 5% | $2,684 |
| Year 3 | 7% | $3,327 | 6% | $2,998 |
| After buydown | 7% | $3,327 | 7% | $3,327 |
In this example, the estimated two-year subsidy is about $11,654. The estimated three-year subsidy is about $22,927. These are arithmetic examples, not advertised terms; an actual lender calculates and documents the required amount.
Official rules that change the decision
Fannie Mae temporary buydowns
- Available for eligible fixed-rate mortgages and certain adjustable-rate plans on principal residences and second homes.
- The initial reduction may not exceed three percentage points, and the payment rate may not increase by more than one percentage point per year.
- The borrower qualifies at the full note rate, without using the reduced payment.
- A written agreement and fully funded custodial account are required.
- If the loan is paid off early, the agreement governs whether unused funds are applied to payoff or returned to the borrower or lender.
VA temporary buydowns
- VA guidance covers eligible purchases, cash-out refinances, and Interest Rate Reduction Refinance Loans.
- The buydown may run one to three years with no more than a one-percentage-point annual payment-rate step.
- Qualification uses the full payment due after the temporary period.
- The agreement must identify the property, term, amount, payment rates, original rate, and party holding the funds.
- A seller- or builder-funded buydown counts toward VA's four-percent seller-concession cap.
FHA, USDA, conventional, VA, jumbo, and lender-specific products do not share one universal rule sheet. Confirm the exact loan program, investor guidance, contribution limits, and written agreement before putting a buydown in an offer.
Compare the same dollars four ways
A buydown is not automatically the best use of a seller credit or buyer cash. Ask for side-by-side written scenarios with the same price, loan amount, lock period, and credit profile.
Temporary buydown
What changes: The required payment during the scheduled subsidy period; the full note rate remains in the loan documents.
What to evaluate: Funding source, written agreement, qualification at the full payment, total subsidy, and what the agreement says about unused funds.
Permanent discount points
What changes: The note rate for the loan term, subject to the selected pricing and closing.
What to evaluate: Upfront points, APR, monthly difference, break-even month, and how long you expect to keep this loan.
Closing-cost credit
What changes: Cash needed at closing, within the loan program and transaction limits.
What to evaluate: Which costs the credit may cover and whether accepting it changes the rate or other terms.
Price reduction
What changes: Purchase price and usually the amount financed, subject to appraisal and final loan structure.
What to evaluate: Down-payment difference, monthly payment, taxes where relevant, and whether the same dollars create more near-term value elsewhere.
Why buyers are asking about buydowns now
Freddie Mac reported a 6.58% national average for a 30-year fixed mortgage on July 23, 2026, up from 6.55% the prior week. That benchmark is not a personalized New Jersey quote, but it explains the attention on first-years payment relief. A buydown should still be compared against the actual rate, APR, points, credits, closing costs, and payment offered for the specific file.
Questions to answer before accepting a buydown
- 1What is the full note rate, APR, points, and monthly principal-and-interest payment?
- 2Who is funding the buydown, and what other concession or price term changes because of it?
- 3What is the exact subsidy amount and where will the funds be held?
- 4Which rate and payment will the lender use to qualify the borrower?
- 5What does the written agreement say happens after a sale, refinance, payoff, transfer, or missed subsidy?
- 6How does the same transaction look with a closing-cost credit, permanent points, or a lower purchase price?
- 7Can the household afford the full payment without assuming future income growth or a future refinance?

Frequently asked questions
What is a 2-1 mortgage buydown?
A 2-1 temporary buydown uses a funded subsidy account to support payments calculated at two percentage points below the full note rate during year one and one percentage point below it during year two. The payment then returns to the full note-rate amount. The note rate itself is not changing during those two years.
What is a 3-2-1 mortgage buydown?
A 3-2-1 temporary buydown generally steps from three percentage points below the note rate in year one, to two points below in year two, to one point below in year three, and then to the full note-rate payment. Fannie Mae limits an eligible temporary reduction to three percentage points with no more than a one-point annual increase; exact availability depends on the loan and lender.
Do I qualify using the lower buydown payment?
Do not assume that. Fannie Mae states that qualification is based on the note rate without considering the bought-down payment. VA likewise requires qualification using the full monthly payment due after the buydown period. The lender must apply the rules for the exact loan program and file.
Can a seller or builder fund a temporary buydown?
A seller, builder, lender, borrower, or another permitted party may be able to fund a buydown depending on the loan program and transaction. The source, amount, interested-party contribution limits, and written agreement must all be documented. VA treats a seller- or builder-funded temporary buydown as a seller concession within its four-percent cap.
What happens to unused buydown funds if I sell or refinance?
The written agreement controls the disposition; unused funds should not be described as automatically forfeited. Fannie Mae permits the agreement to provide for unused funds to be applied in connection with payoff or returned to the borrower or lender. Read the actual agreement before deciding.
Is a temporary buydown the same as paying discount points?
No. A temporary buydown supports a scheduled lower payment for a limited period while the note rate stays unchanged. Discount points are an upfront charge associated with a permanently lower note rate for that loan. Compare written pricing, APR, payment, total loan costs, and your planning horizon.
Is a buydown guaranteed to save me money?
No. The result depends on who funds it, the price or credits given up to obtain it, the loan terms, how long you keep the loan, and what the written agreement does with unused funds. Compare the same transaction with and without the buydown before choosing.
