Rate Buydown vs. Price Reduction in San Diego: Which Saves More?

If a San Diego seller hands you $20,000, taking it as a rate buydown instead of a price reduction can cut your monthly payment by roughly three times as much. On an $800,000 loan, a $20,000 price cut saves about $103 a month. That same $20,000 applied to buying the rate down saves about $339 a month. Same seller, same money, completely different outcome.

This is the single most common question on my buyer calls right now, so let’s do the math in public.

San Diego buyers finally have something to ask for

If you’re shopping anywhere from Clairemont to Carmel Valley right now, you’ve probably noticed listings sitting longer than they did a year ago. San Diego days on market have stretched out of the 19–24 day range and into the high 20s and 30s, and inventory has been climbing all summer. When a house sits, the seller starts listening.

At the same time, financing costs have been drifting down. Freddie Mac’s Primary Mortgage Market Survey put the 30-year fixed national average at 6.65% on August 20, 2026 — down from 6.67% the week before, and the third consecutive weekly decline. A year ago it averaged 6.58%.

So you have leverage. The problem is that almost everybody spends it on the wrong thing.

Why the price reduction feels better (and usually isn’t)

A price cut feels like winning. It’s a number you can say out loud at dinner. “We got them down twenty grand.”

A rate buydown feels like a lender trick. It’s abstract, it involves the word “points,” and nobody brags about it at dinner.

But you don’t make payments on the sales price. You make payments on the loan, at the rate. A dollar aimed at the rate moves the payment far harder than a dollar aimed at the price.

The math: one $20,000 credit, two different lives

Assume a $1,000,000 San Diego purchase, 20% down, 30-year fixed, starting at that 6.65% national average. Your actual rate will differ.

What you ask for	Loan amount	Rate	Monthly P&I	Monthly savings
Nothing	$800,000	6.65%	$5,135.72	—
$20,000 price reduction	$784,000	6.65%	$5,033.00	$102.72
$20,000 permanent rate buydown	$800,000	~6.00%	$4,796.40	$339.32

Over ten years in the home, the buydown puts roughly $28,400 more in your pocket than the price cut does. Ride it the full thirty years and the interest difference between 6.65% and 6.00% on that loan is about $122,000. That’s not a rounding error. That’s a kid’s tuition.

The price reduction only shaves 2% off your loan. The buydown works on 100% of it. That’s the whole reason the gap is so wide.

What a permanent rate buydown actually is

You’re pre-paying interest. Discount points are a fee paid at closing in exchange for a permanently lower note rate for the life of the loan.

The industry rule of thumb is that roughly one point (1% of the loan amount) buys somewhere in the neighborhood of a quarter percent. That rule of thumb is exactly that. Actual point pricing moves daily with the bond market and varies by loan type, credit profile, and property. The 6.00% above illustrates what $20,000 might do on an $800,000 loan — it is not a quote, an offer, or a commitment. The CFPB’s explainer on discount points is worth ten minutes of your evening.

The critical piece: the seller can pay for it. When a credit goes toward your closing costs and points instead of the price, you keep the lower payment for as long as you keep the loan.

The 2-1 buydown: big relief now, nothing later

There’s a second flavor. A temporary 2-1 buydown drops your rate 2% in year one and 1% in year two, then returns to the note rate in year three. The seller funds an escrow account that covers the difference. On that same $800,000 loan at a 6.65% note rate:

Year	Effective rate	Monthly P&I	Monthly savings
Year 1	4.65%	$4,125.09	$1,010.63
Year 2	5.65%	$4,617.89	$517.83
Year 3 and after	6.65%	$5,135.72	$0

Total subsidy: roughly $18,300, right in the same range as our $20,000 credit.

Look at year one. A thousand dollars a month is enormous relief in the exact window when you’re buying blinds, fixing the sprinkler system nobody disclosed, and discovering what San Diego irrigation costs.

Now look at year three. You’re back to $5,135.72 — and you have to qualify at the full note rate anyway, because a temporary buydown doesn’t help you get approved. If that payment scares you in year three, it should scare you in year one.

When the price reduction is genuinely the better move

I’d rather talk you out of a buydown than sell you one you don’t need. Take the price cut when:

• You’re paying cash or putting a lot down. No loan, no rate to buy down.
• You don’t expect to keep the loan long. Sell or refinance inside roughly three years and you may never recover the cost. Run the break-even math first.
• You need cash, not payment relief. A credit that lowers your cash to close can matter more than $300 a month if closing day is tight.
• The price cut drops you under a loan-limit threshold. Getting under the San Diego County conforming ceiling can change your pricing structurally — sometimes worth more than points.
• The appraisal came in low. Then the reduction isn’t a negotiation, it’s a correction. Take it.

That last one matters. A buydown can’t fix an overpriced house. It just makes an overpriced house feel affordable, which is a different and more expensive problem.

How to actually ask for it

Don’t open with “will you buy down my rate?” Ask for a number instead: “We’ll come up to your price if the seller contributes $20,000 toward our closing costs and rate.”

Sellers care about the headline sale price — it’s what shows in the comps and what they tell the neighbors. You care about the payment. That trade is available far more often than buyers realize, and on a house that’s been sitting 30 days it’s a conversation, not an insult.

One caution: loan programs cap how much a seller may contribute, and the cap changes with your loan type and down payment. Have your lender tell you the ceiling before you write the offer. Asking for more than the program allows just burns a negotiation round.

Frequently asked questions

Can I get a rate buydown and a price reduction?

Sometimes. It depends on what the seller will fund and what your loan program’s contribution limits allow. Usually it’s a question of dividing one pot, not creating two.

Is a buydown still worth it if rates keep falling?

That’s the honest risk. If you refinance in two years, a permanent buydown may not pay for itself, which is why the break-even calculation matters more than the monthly savings figure. Nobody — including me — knows where rates go next.

Does a buydown help me qualify for the loan?

A permanent buydown lowers your note rate, so it affects qualifying. A temporary 2-1 buydown does not — you qualify at the full note rate.

What happens to the money if I sell during a 2-1 buydown?

Unused subsidy sitting in the escrow account is typically applied to your loan balance. Ask your lender to confirm how your specific program handles it.
