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 25 – September 24)

The Mid-Peninsula closed 155 homes in the last 30 days — 51 just this week. The typical home sold for $2.50M and went for 104.6% of asking, so sellers are still getting a premium over list. San Mateo led volume in both segments (25 single-family, 14 condos/townhomes), with Redwood City and Palo Alto close behind on single-family; Hillsborough ($6.00M median) and Palo Alto ($4.14M) set the pace on price.

Single-Family by Price Point

Here's how the 114 single-family sales from the last 30 days broke out by price.

Under $2M: 28 sold at 106% of list in about 16 days.
$2–3M: 27 sold at 105% of list in about 16 days.
$3–4.5M: busiest tier and ran the hottest — 43 sold at 108% of list in about 20 days.
$4.5M+ held up: 16 sold at 107% of list in about 11 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

Single-family is holding its pace: over 30 days, 114 sold in about 17 days at 106.7% of list, and this week's 34 closings came in at 107.4% of list in about 20 days. This week's single-family closings skewed slightly higher-priced ($3.20M median vs. $3.15M for the month). Condos and townhomes are the softer side: 41 sold at 98.8% of list over 30 days. Their 49-day average is inflated by a few long-sitting units (the longest took 195 days); the 30-day median is 23 days. This week's condo closings did run slower, with a median of 47 days, so condo buyers have real room to negotiate.

The Move Math

Here's what today's numbers mean for a move, using current medians and this week's 7.03% 30-year rate. (Payments are principal + interest, 20% down; taxes and insurance are on top.)

Trading up — condo to single-family:

Median condo $1.14M → 20% down, finance 80%, P&I ≈ $6,075/month + HOA (many buyers are investors and all cash).
Median single-family $3.15M → P&I ≈ $16,816/month (buyers today often put 40–50% down or pay all cash due to rates and opportunity cost).

That's a gap of about $10,741/month in principal and interest alone.

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 — up to three times, anywhere in the state. On a long-held home, that can mean keeping a tax bill tied to a $500–700K assessed value instead of today's price — often $20,000+ a year saved.

The Macro Corner.

Mortgage rates: The 30-year fixed averaged 7.03% this week (Freddie Mac, Sept 24), up from 6.95% last week and 6.30% a year ago. The 15-year is 6.42%.
The Fed: Raised rates a quarter point on Sept 16 to 3.75%–4.00%, its first hike since 2023. Next meeting is Oct 28.
Inflation: August CPI ran 3.4% year over year, pushed by gas prices; core CPI eased to 2.4%. Core PCE, the Fed's preferred gauge, was 3.3% in July.
Wall Street: Through Wednesday, the S&P 500 was up 0.7%, the Dow down 0.3% and the Nasdaq up 1.6% for the week, as the 10-year Treasury yield hit 5.11%, its highest since 2007.
Bottom line: Rates just crossed 7% and the Fed is tightening, yet single-family homes here are still selling at 107% of list in about 17 days. Tight supply is setting local prices more than rates are.
