In July 2026, 59 single-family homes closed in San Mateo at a median of $2,070,000, or $1,344 per square foot. Sellers collected 108% of their list price, and the average sale took 16 days.

That is a seller's market by any measure. Buyers in San Mateo are competing, and homes that are prepared, priced, and marketed well are clearing above asking. The spread between a well-run sale and a passive one is widest in exactly these conditions.

Supply stays tight: San Mateo carried 0.4 months of inventory in July 2026. Serious buyers have little to choose from, which is precisely the environment where a well-presented home commands its price.

What do homes sell for in San Mateo?
The median single-family sale in San Mateo was $2,070,000 in July 2026, at $1,344 per square foot. Across all of 2025, the median was $2,087,500. Individual homes range widely around the median depending on size, condition, and street.
How long does it take to sell a house in San Mateo?
The average San Mateo single-family sale took 16 days in July 2026. Well-prepared, correctly priced homes typically clear faster than the average; overpriced homes sit past it and often sell for less after a reduction.
Do homes in San Mateo sell over asking?
Yes, on average. San Mateo sellers collected 108% of list price in July 2026, which means the typical home sold at or above asking. Pricing to invite competition, rather than pricing at the ceiling, is what produces those results.
What does it cost to sell a home in San Mateo?
The main costs are agent commissions (negotiable, and set in your listing agreement), county transfer tax, title and escrow fees, and any repairs or preparation you choose to invest in. The seller net sheet calculator on this site turns those into a single walk-away number for your price point.
When is the best time to list a home in San Mateo?
Spring and early fall bring the most buyer activity on the Peninsula, but the best month depends on inventory: listing when few comparable homes are active often beats listing in the busiest season. The listing timing calculator on this site shows the historical pattern, and Lisa reads current inventory before recommending a date.
How do I find out what my home is actually worth?
Automated estimates miss condition, upgrades, lot, and street. Lisa prepares a free, confidential valuation for your specific property, drawing on closed sales, active competition, and off-market activity, within 24 hours. Request it at lisamlum.com/selling/home-valuation.
