Same Budget, Two Paths: Buy Down the Rate or Buy Down the House?

Asking the seller to cut the price feels like the obvious win. Most buyers stop there. But the same $12,000 in leverage can work very differently depending on where it goes. Here is the comparison most people never run.

Why a Lower Purchase Price Is Not Always the Biggest Win

When you negotiate a price reduction, that savings does not flow one-for-one into your loan. If you are putting 20% down, only 80% of the price cut reduces your loan balance. The other 20% becomes extra down payment.

On a $400,000 home with 20% down, a $12,000 price cut brings your loan from $320,000 to $310,400, a reduction of $9,600. Your interest rate, applied to that entire remaining balance, stays exactly where it was.

That is the part most people miss. The rate is not touched. Only a fraction of the principal is.

What Discount Points Actually Buy

One discount point equals 1% of your loan amount, paid upfront at closing. In exchange, the lender reduces your interest rate for the life of the loan.

The exact reduction per point varies by lender and changes with market conditions. Confirm the trade-off on your lender’s current rate sheet before running any math. A commonly referenced rule of thumb is roughly 0.25% per point, but your actual pricing may be higher or lower.

The Consumer Financial Protection Bureau provides a useful reference: on a $180,000 loan, paying 0.375 points ($675 upfront) reduced the rate enough to save approximately $14 per month. The monthly savings may look small at that scale, but the impact grows on a larger loan.

Note that the note rate and APR are not the same thing. APR includes certain fees and costs associated with the loan and will be disclosed in your Loan Estimate.

The One Calculation Most Buyers Skip

Before comparing a price reduction with a rate buydown, calculate the breakeven point: the month when cumulative monthly savings fully recover the upfront cost.

Breakeven formula: Breakeven (months) = Upfront cost / Monthly savings

Assumptions for this example:

  • Loan amount: $320,000
  • Term: 30-year fixed
  • Starting note rate: 6.48% (Freddie Mac PMMS, week ending June 4, 2026)
  • Seller concession applied to points: $12,000, equal to 3.75 points
  • Assumed rate reduction: 0.25% per point (illustrative; your lender’s actual pricing will differ)
  • Reference hold period: 7 years

At 0.25% reduction per point, 3.75 points brings the rate from 6.48% down to approximately 5.54%.

Scenario Note Rate Monthly P+I
No points 6.48% $2,018
3.75 points 5.54% $1,825

Monthly savings: $2,018 minus $1,825 = $193

Breakeven: $12,000 / $193 = 62 months, or about 5.2 years

Hold the loan past that point and every month after returns $193. Over a 7-year hold, savings beyond breakeven total roughly $4,000.

(All figures are principal and interest only. Your APR will differ from the note rate and will be disclosed in your Loan Estimate.)

The Same $12,000, Side by Side

Price Reduction Rate Buydown
Seller contribution $12,000 $12,000
Monthly savings About $60 About $193
Loan balance reduced Yes No
Interest rate reduced No Yes
Breakeven required No Yes, about 5.2 years

Two strategies, same budget, very different monthly results. Here is why.

A price reduction shaves $12,000 off the purchase price. With 20% down, only 80% of that flows into your loan balance. Your rate stays at 6.48% (Freddie Mac PMMS, week ending June 4, 2026), applied to a slightly smaller number.

A rate buydown applies that same $12,000 directly against the percentage the lender charges on your entire balance. Every dollar of the $320,000 loan gets cheaper, for every month you hold it.

That is the gap between $60 and $193 a month. Not the size of the investment. The target it hits.

One practical note: seller concession caps vary by loan type and are set by lender guidelines for the current cycle. Confirm the applicable cap for your loan type with your loan officer before structuring an offer.

Where Lender Credits Fit Into the Picture

Lender credits work in the opposite direction. Instead of paying more upfront to lower the rate, you accept a higher rate and receive assistance with closing costs.

This can reduce the cash required at closing, but it typically increases the monthly payment. That is why “no closing costs” does not mean no cost. The expense is shifted from closing day to future interest payments over the life of the loan.

Whether that trade-off makes sense depends on your expected time in the home, available cash reserves, and future refinance plans.

Three Questions Worth Asking Your Loan Officer

The numbers above are illustrations. Your actual breakeven depends on your loan amount, your lender’s pricing per point today, and your realistic hold period.

Before comparing options, ask your loan officer:

  1. What is the current cost and rate reduction available per discount point on today’s rate sheet?
  2. What is the breakeven period for my specific loan scenario and hold timeline?
  3. What seller concession limits apply to my loan program under current guidelines?

Your loan officer can model all three scenarios against your real numbers. That comparison is what an informed decision looks like.

A lower purchase price and a lower interest rate are not the same thing, even when they use the same dollar amount. The rate buydown reaches every dollar of the loan balance. The price cut reaches only a fraction of it. Start by asking your loan officer to run the breakeven on your actual numbers. The most common mistake is choosing based on the headline dollar figure rather than the monthly impact over your real hold period.
