Rate Buydown Explained: What Paying Points Can Actually Save

With higher mortgage rates, more buyers are asking whether paying points to buy down a rate is worth it. The honest answer is: sometimes—but only after comparing the upfront cost, the monthly savings, and how long you expect to keep the loan.

A discount point is an upfront charge equal to 1% of the loan amount. It does not guarantee a fixed rate reduction. The rate change a point buys depends on the lender, loan program, credit profile, lock period, and market pricing on the day you apply.

A simple $400,000-loan illustration

The Ready Front graphic uses a 30-year fixed loan with a $400,000 loan amount. For context, that could be a $500,000 home with 20% down. Freddie Mac's 30-year benchmark was 7.28% on October 1, 2026. The figures below are principal and interest only—property taxes, homeowners insurance, HOA dues, mortgage insurance, and closing costs are not included.

Illustrative rate	Upfront cost	Estimated P&I	Monthly savings
7.28%	$0	$2,737	—
7.03%	$4,000	$2,670	$67/mo
6.78%	$8,000	$2,602	$135/mo
6.53%	$12,000	$2,536	$201/mo
6.28%	$16,000	$2,472	$265/mo

That table is an illustration, not a quote or a promise of lender pricing. The point of the example is to show the tradeoff: a lower payment comes with more cash due at closing.

The break-even question

In this illustration, each $4,000 step breaks even at roughly five years. The first step saves about $67 a month; $4,000 divided by $67 is close to 60 months. The same math is similar at the larger steps because the cost and savings increase together.

If you sell, refinance, or pay off the loan before that break-even point, you may not recover the upfront cost through lower payments. If you expect to keep the loan longer, the lower payment may be more valuable. Neither answer is automatic.

Credits can change the decision

In the Austin-area market, a seller or builder credit can sometimes be used toward eligible closing costs or lender-paid points. That does not turn a buydown into free money, but it can change whose cash is being used and whether the comparison makes sense. Eligibility and limits come from the loan program and lender—not a social post.

What to ask before paying points

• What is the exact lender quote at the same lock period with and without points?
• How many dollars are due for each option, and what does that buy down in rate?
• What is the payment difference after taxes, insurance, HOA, and mortgage insurance?
• What is the break-even timeline?
• Could a seller or builder credit be applied, and are you likely to refinance or move first?
