If a lower mortgage payment in year one or two would help you buy in Redwood City, a seller-paid rate buydown might be the tool you need. In a high-cost market like San Mateo County, every dollar of monthly cash flow matters. You want a clear way to compare a buydown against a price cut and to understand how lenders will treat it. This guide breaks down how 2-1 and 3-2-1 buydowns work, what they cost, program limits, and how to use them in local negotiations. Let’s dive in.
Understand seller rate buydowns
A rate buydown happens when a third party, often the seller, pays money at closing to reduce your mortgage interest rate. You still sign a note at the full rate for the life of the loan, but your early payments can be lower if the buydown is temporary. The funds cover the difference between the full payment and the reduced payment during the buydown period.
There are two broad categories you should know:
- Temporary buydown lowers your principal and interest for a set period, usually 1 to 3 years. After that, your payment returns to the note rate.
- Permanent buydown (discount points) lowers the note rate for the full term. Pricing depends on live lender rate sheets.
Common temporary buydown structures
- 2-1 buydown: Year 1 is note minus 2 percentage points, Year 2 is note minus 1 point, then the note rate thereafter.
- 3-2-1 buydown: Year 1 is note minus 3 points, Year 2 minus 2, Year 3 minus 1, then the note rate.
- 1-0 buydown: One year at 1 point below the note rate. Always confirm the exact schedule in your contract.
How the math works
Lenders usually require the seller to deposit the full dollar amount needed to cover the payment shortfall during the buydown period. The lender compares the monthly principal and interest at the note rate with the reduced payment, then escrows that difference to fund your lower payments.
Here is a simple illustration of size and tradeoffs. Assumptions: 30-year fixed, $1,000,000 loan, 7.00% note rate. Rounded monthly principal and interest examples:
- At 7.00%: about $6,653
- At 6.00%: about $5,996
- At 5.00%: about $5,368
- At 4.00%: about $4,774
For a 2-1 buydown, year 1 would be based on 5.00% (about $5,368) and year 2 on 6.00% (about $5,996), then it reverts to the full note payment. The approximate seller subsidy totals about $23,308 for two years. For a 3-2-1 buydown, the three-year subsidy totals about $45,854. These figures are examples to show scale. Your lender will calculate the exact amount.
Remember, a buydown only changes principal and interest. Taxes, homeowner’s insurance, HOA dues, and any special assessments such as Mello-Roos do not change.
Program rules and seller-concession limits
A buydown is usually funded through seller concessions. Each loan program has limits you must follow:
- Conventional conforming loans typically cap seller concessions based on your down payment and occupancy. A common structure is 3% if you put less than 10% down, up to 6% for 10% to 25% down, and up to 9% if you put more than 25% down. Always confirm with your lender.
- FHA loans have historically allowed seller contributions up to 6% for certain closing costs and prepaid items. Verify how a buydown is treated with your FHA lender.
- VA loans permit seller concessions for certain items, with program-specific rules your lender will explain.
- Jumbo loans and portfolio products, which are common in Redwood City, vary by lender and are often more conservative. Get written guidance from your specific lender.
How buydowns affect qualifying
There is a key difference between your actual payment and the payment the lender uses to qualify you.
- Many lenders qualify you at the full note rate, not the reduced buydown payment. In that case, a temporary buydown improves cash flow but not your qualifying ratios.
- Some lenders may allow qualifying at the reduced payment if the buydown funds are escrowed, documentation is in place, and investor guidelines permit it. Practices vary, so get written confirmation from your lender before you write an offer.
Lenders typically require a signed buydown agreement and proof that funds will be available to make the reduced payments. Some lenders may charge administrative fees for setup. A temporary buydown does not change appraised value, since appraisers focus on comparable sales and property features, not financing concessions.
Redwood City negotiation tips
Redwood City and San Mateo County are high-cost, high-demand markets. In strong seller markets, sellers often prefer a higher price and fewer concessions. In slower periods, you may see more seller-paid buydowns.
When a seller-paid buydown can make sense here:
- You want to maintain the full contract price, yet broaden the buyer pool by easing near-term payments.
- Buyer affordability is the immediate obstacle, and a payment reduction for one to three years can bridge the gap.
- You prefer to avoid a price cut that could influence future comparable sales or negotiating leverage.
When to be cautious as a buyer:
- If your lender will underwrite at the note rate, a temporary buydown may not help you qualify.
- If your long-term budget cannot support the note-rate payment after the buydown ends, the step-up could be uncomfortable.
- Taxes, insurance, HOA dues, and special assessments in San Mateo County can be sizable. Model your full payment, not just principal and interest.
How it interacts with other incentives:
- A seller credit to fund a buydown can be more attractive than a price cut if appraisal support is tight.
- Paying permanent discount points affects the note rate for the full term, while a temporary buydown front-loads payment relief. Each option changes cash at close, monthly payments, and seller net proceeds differently.
Quick buyer checklist
- Ask your lender early:
- Will you qualify me at the note rate or the reduced buydown payment?
- What exact dollar amount must be deposited to fund the buydown? Get it in writing.
- Are there lender fees or overlays for temporary buydowns, especially for jumbo loans?
- How will the funds be documented and disbursed during the term?
- Model payment shock. Calculate your total monthly cost in each year, including taxes, insurance, and HOA.
- Verify closing costs and credits. Make sure the contract and escrow instructions clearly state the buydown terms.
- Talk with a tax advisor if you have questions about how seller-paid costs affect you.
Quick seller checklist
- Get lender validation of the buydown cost and process before you commit in the offer.
- Compare a buydown to a price reduction in terms of net proceeds, timing, and your goals.
- Specify in the contract and escrow instructions:
- The dollar amount of the seller credit
- Purpose and schedule, for example, 2-1 or 3-2-1
- Confirmation that the buyer’s lender has approved the structure
- Who pays any lender or escrow admin fees
- Coordinate with escrow and title so funds are credited and disbursed correctly.
Practical local checks in San Mateo County
- Confirm any Mello-Roos or special assessments for the property. These can meaningfully change your monthly cost.
- Verify HOA dues and services. A buydown does not reduce HOA dues.
- Work with a lender who regularly closes jumbo and portfolio loans in San Mateo County. Concession rules can differ.
Example: using a buydown to keep price intact
Say a Redwood City home shows well but buyers are focused on monthly payments. Instead of reducing price, a seller could offer a temporary buydown to improve first-year and second-year cash flow. For multi-year buydowns, the subsidy is often a few percent of the loan amount. If the property is expected to appraise at full price, a buydown can help bridge affordability without changing comparables.
How to talk to your lender and agent
- Share your target monthly budget and time horizon in the home. If you expect income changes or plan to refinance, a temporary buydown may be useful.
- Request two to three written scenarios: no buydown, 2-1, and 3-2-1. Compare total cash to close, monthly payments by year, and your qualifying status.
- Make the contract language precise. Identify who pays, the exact dollar amount, the buydown schedule, and any fees.
