Reading it right
- Under a budget usually means smaller, and sometimes in need of work. Check the size, condition and lot along with the price.
- A list price under your budget isn’t a sale price under it: 65% of these sold over asking. Our Offer Lab shows how much over, by price.
- Prices move. These are two years of sales; ask us what the same streets are selling for this month.
How we counted
Closed sales of houses (MLS property type “single family home”) with a Foster City address between October 28, 2024 and October 27, 2026, reported to the MLS and read through the IDX feeds that power our home search, with repeat records from different feeds removed (same normalized address or same MLS number, plus the same sale date). Sales under $400,000 are left out: most are mobile homes in parks or partial-interest sales. Neighborhoods are our guides’ outlines, placed by each sale’s map position. Features are counted when the listing description mentions them. Past sales aren’t a forecast or the value of any one home.
