Every July I get the same question on the Peninsula, just worded a dozen different ways: “Mark, is this summer the top, or is there still room to run?” After 24 years here, I’ve learned not to answer from a headline. I pull the San Mateo County numbers and check them against how my own escrows are actually closing. So here’s my honest mid-year read on the San Mateo County real estate market in 2026: single-family prices are still up year-over-year, well-prepared homes are still selling in about two weeks, and inventory is still tight. This isn’t a market that’s breaking. It’s a market that rewards preparation and quietly punishes guesswork — and that should shape every decision you make between now and fall.
Where Peninsula Prices and Pace Actually Sit Right Now
Countywide, the single-family median is running near $2.2 million, up roughly 6% from a year ago, with homes selling in about 14 days on average. We closed 2025 at the highest median in county history, and 2026 hasn’t given that back. Supply is still thin — months of inventory remain well below what a balanced market would carry — so the fundamental shortage that has defined SF Peninsula home prices for a decade is still very much in place.
But that countywide figure hides how differently each town behaves. Burlingame sits near the top, with a median close to $2.85 million and a real share of homes selling over ask. San Carlos runs around $2 million and rewards buyers who move on the right house. And Redwood City still offers the lower entry point where I send value-minded buyers. One county, five different markets.
Here’s how I help: Before I price or write an offer anywhere, I split a town into its real submarkets — renovated, fixer, and the awkward middle — and pull comps against each one separately, never against a townwide average that describes no actual house.
If You’re Selling This Summer: Timing Is a Lever, Not a Gamble
With supply this tight, sellers have genuine strength — but only if they launch ready. The homes pulling multiple offers in Hillsborough and Burlingame this year aren’t the ones that rushed on; they’re the ones that came out staged, pre-inspected, and photographed for a phone screen, priced to the strict comp set rather than to a hopeful number.
I had a Burlingame seller this spring who wanted to list immediately at an aspirational figure. We held two extra weeks, did targeted prep, priced to the comps — and pulled multiple offers inside ten days, well over the number we’d have gotten by going first and unprepared. On a Peninsula home, the gap between “ready” and “rushed” is routinely six figures. The instinct to be first almost always loses to the discipline of being ready.
Here’s how I help: I build a roughly 21-day pre-listing runway — stage by day 7, photos by day 14, launch by day 21 — and time the go-live to the week with the least competing inventory on your block.
If You’re Buying: Move on the Right House, Not Every House
For buyers, a tight-but-saner market is a gift. The panic-bidding of a couple of years ago has eased, and I’m again negotiating real terms — inspection contingencies, credits, closing flexibility — on homes that lingered or were priced too high. The well-priced, move-in-ready listings still go fast, so the leverage lives in the over-priced and over-sat inventory, not in waiting for a countywide discount the data simply doesn’t support.
The mistake I watch buyers make at mid-year is holding out for a “crash.” With the county still up year-over-year and homes selling in about two weeks, this isn’t a falling market — it’s a more reasonable one.

Frequently Asked Questions
Q: What is the median home price in San Mateo County right now?
The single-family median is running near $2.2 million, up about 6% year-over-year. But towns vary enormously — Redwood City lower on entry, Burlingame near $2.85 million, the top of Hillsborough far higher.
Q: Are SF Peninsula home prices going up or down in 2026?
Up, overall — the county is positive year-over-year and closed 2025 at a record median. A few submarkets and the condo segment have flattened, so this is a selective market, not a declining one.
Q: Is it a buyer’s or seller’s market on the Peninsula this summer?
Both, depending on the house. Sellers hold the edge on prepared, well-priced listings because inventory is tight; buyers have regained leverage on overpriced and lingering homes.
Q: Should I sell my Peninsula home now or wait until fall?
If your home will be genuinely ready, summer’s tight inventory is an advantage. The bigger variable isn’t the calendar — it’s whether you launch staged, pre-inspected, and priced to the comps.
