Here's this week's San Mateo County housing market read across the ten Mid-Peninsula cities I track: Belmont, Burlingame, Foster City, Hillsborough, Menlo Park, Palo Alto, Redwood City, Redwood Shores, San Carlos, and San Mateo.

Local Market Activity (August 18 – September 17)

The Mid-Peninsula closed 142 homes in the last 30 days — 54 just this week. The typical home sold for $2.38M and went for 104.7% of asking, so sellers are still getting a premium over list. San Mateo and Redwood City led on volume, while Hillsborough (median $8.25M) and Menlo Park ($3.82M) sat at the top of the price charts.

Single-Family by Price Point

Single-family sales split cleanly across four price tiers, and buyers are paying over asking in every one. Under $2M: 28 sold at 105% of list in about 24 days. The $2–3M band moved fastest — 29 sold at 106% of list in just 13 days. The $3–4.5M tier ran hottest and busiest — 37 sold at 107% of list in about 20 days. Even $4.5M+ held up, with 13 sold at 105% of list in 15 days. Over-asking isn't just an entry-level story here — it runs all the way up the price ladder.

This Week vs. the 30-Day Pace

This week's closings held right in line with the trailing 30-day trend. Single-family homes are moving in about 19 days at 106% of list; condos and townhomes take longer, with a 30-day average near 33 days and about 100% of list. That condo average is skewed by one unit that sat 146 days — the typical condo actually closed in about 14 days, so nothing sudden is happening in that segment. One note on the single-family homes that closed this week: they skewed higher-priced ($3.01M median vs. $2.88M over the full 30 days), which nudges the weekly median a touch above the running pace.

The Move Math

Here's what today's numbers mean for a move, using current medians and this week's 6.95% 30-year rate. (Payments are principal + interest, 20% down; taxes and insurance are on top.)

Trading up — condo to single-family:

Median condo $1.25M: 20% down, finance 80%, P&I ≈ $6,619/month plus HOA. Many condo buyers here are investors and pay all cash.
Median single-family $2.88M: P&I ≈ $15,225/month. Buyers at this level today often put 40–50% down or pay all cash given rates and opportunity cost.

That's a monthly jump of about $8,606 in principal and interest alone — before taxes, insurance, and upkeep.

Downsizing at 55+ — don't forget Prop 19.

If you're 55 or older, Prop 19 lets you carry your existing low property-tax base to your next California home — you can do it up to three times, anywhere in the state. On a home you've owned for decades, that can mean keeping a tax bill tied to a $500–700K assessed value instead of today's sale price, often $20,000+ a year in savings. It's the single biggest reason a lot of longtime owners can finally afford to right-size.

The Macro Corner

Mortgage rates: the 30-year fixed averaged 6.95% this week (Freddie Mac), up from 6.76% a week ago and 6.26% a year ago; the 15-year sits at 6.26%.
The Fed: raised its target range 25 bps to 3.75–4% on Sept 16 — its first hike since 2023 — and signaled it could move again this year. Next meeting: Oct 27–28.
Inflation: core CPI cooled to 2.4% year over year in August, though headline CPI is 3.4% on higher gas prices; core PCE, the Fed's preferred gauge, sits at 3.3%.
Wall Street: stocks sank on the rate hike — the Dow shed about 600 points Wednesday — then clawed back Thursday (S&P +1.1%, Nasdaq +1.6%) as oil and bond yields eased.
Bottom line: financing costs ticked up, but Peninsula inventory stays tight — and locally, scarce supply drives prices far more than the rate headlines.
