Why Foster City for investors
Planned 1960s waterfront community. Lagoons throughout. Dense townhome stock, some SFR. San Mateo Foster City School District has strong schools. Diverse, family-anchored.
Roger\'s read: Mariner's Island offers the most lagoon-front homes. The east end (closer to Beach Park) is the value play. School-district consistency across the city is unusually strong.
