Living in Edgewater Isle
Edgewater Isle is something of a San Mateo oddity: a condo and townhome community east of Highway 101 near the Marina Lagoon, closer to Foster City than to downtown. All of its sales are condos and townhomes, with a 2025 median around $925K, and the market is steady, with homes selling at about 100% of asking in both 2025 and 2026.
Parking & walkability: Homes include assigned or garage parking, with guest parking more limited. The lagoon paths and the Bay Trail are close by, Bridgepointe and Hillsdale's shopping are a short drive, and Highway 92 and 101 are just a few minutes away.

Borders are built lot by lot from the county's property lines and where homes have been listed (MLS neighborhood codes), and stay inside official city limits (dashed), so a home or two along an edge may differ from official MLS lines.
