Why Are Mortgage Rates Rising Again — And What Should Bay Area Buyers Do Right Now?

If you've been watching mortgage rates lately, you've probably noticed them creeping upward. As of June 3, 2026, the national average for a 30-year fixed purchase loan is hovering around 6.37% to 6.59%, depending on the lender and borrower profile — and it's been nudging higher each week.

For buyers in San Jose, Campbell, and across Santa Clara County, this can feel discouraging. So what's actually going on, and what should you do about it?

Short Answer

Mortgage rates are rising primarily because of inflation concerns tied to geopolitical conflict, which is pushing oil prices — and the cost of everything else — higher. The bond market reacts to inflation by demanding higher yields, and mortgage rates follow. There's no imminent reversal on the horizon, but this environment is still workable for well-prepared buyers.

How This Plays Out in Santa Clara County

Inventory is still tight. Santa Clara County's unsold inventory index sits at just over 2 months — well below the 3-4 months that defines a balanced market. Competition among buyers hasn't gone away, even as rates rise.

Prices remain elevated. The statewide median has crossed $900,000, and the South Bay sits well above that. Even a modest uptick in inventory hasn't translated into meaningful price relief for most buyers.

Jumbo loans are especially relevant here. Because Bay Area purchase prices routinely exceed conforming loan limits, many buyers finance with jumbo products. Jumbo rates don't always move in lockstep with conventional averages — meaning there can be real opportunity to shop lenders and find competitive pricing even when headline rates look rough.

Common Misunderstandings

"I should just wait for rates to come down." Waiting for rates in the Bay Area has historically cost buyers more in appreciation than they saved in interest. If rates do drop meaningfully, expect competition to increase and prices to firm up further. You can always refinance; you can't go back in time to buy a house at last year's price.

"A higher rate means I can't afford to buy." Not necessarily. Seller concessions, buydowns, adjustable-rate products, and choosing the right loan structure can all affect your real-world payment.

"All lenders have the same rates." They don't. Rates vary meaningfully from lender to lender. Shopping two or three lenders on the same day can surface real differences — sometimes thousands of dollars over the life of a loan.

What to Think About Before Deciding

• How long do you plan to stay in the home? The longer your horizon, the less short-term rate fluctuations matter.
• Is your financial picture solid? Credit score, down payment reserves, and debt-to-income ratio are your negotiating power.
• Do you understand your loan options? Conventional, jumbo, FHA, VA, ARM vs. fixed — each has a different profile.
• Have you been pre-approved recently? Pre-approvals from even three months ago may not reflect current rate environments.

Frequently Asked Questions

Why are mortgage rates going up in 2026?

The primary driver is inflation tied to rising oil prices from geopolitical conflict. Higher inflation puts upward pressure on Treasury yields, which mortgage rates closely follow.

Will mortgage rates come back down in 2026?

Forecasts suggest rates will remain in the mid-to-low 6% range through 2026, with modest dips possible. A dramatic drop to the 5% range is not broadly expected in the near term.

Is it still a good time to buy a home in San Jose or Santa Clara County?

That depends on your personal financial situation and timeline. Inventory remains tight and prices are elevated, but a well-prepared buyer with solid credit can absolutely find opportunity.

What is a mortgage rate buydown and should I consider one?

A buydown temporarily or permanently reduces your interest rate by paying points upfront, sometimes funded by seller concessions. Whether it's right for you depends on your situation.

What's the difference between a jumbo loan and a conventional loan in the Bay Area?

Conforming (conventional) loans are capped at a loan limit set annually by the FHFA — for 2026, that's $832,750 nationally, with Santa Clara County's high-cost conforming limit reaching $1,249,125. Anything above that is a jumbo loan. Given Bay Area home prices, many buyers here end up in jumbo territory without realizing it until they start the loan process.
