Market Analysis: 94404 Foster City

ZIP 94404 in Foster City, CA carries a robust set of headwinds. Home values near $1.7M and rents of $4,302/mo sit inside a market where underwriting has to be tight.

Distressed markets are won on execution, not on spreadsheets. ZIP 94404 registers the profile where tenant screening, deferred maintenance, and local relationships determine the outcome.

Nearby ZIPs in Foster City have seen price recovery that 94404 has not matched. San Mateo County data supports the view that the spread is structural rather than temporary.

The demographic picture in 94404 includes headwinds that any investor should price in. Income distribution skews lower than Foster City averages, and tenant stability requires active management.

Negative Leverage — IRR / Tax Play Cap Rate: 2.0%  |  30yr Rate: 6.8%
Leverage reduces cash returns at current rates.

The current 30-yr mortgage rate (6.8%) exceeds the estimated cap rate (2.0%). Financing reduces your cash-on-cash return below the cap rate. Markets like this may still make sense as IRR plays — factoring in appreciation, depreciation, and a future refinance when rates drop.

About Repit School Scores

Traditional school ratings rely heavily on standardized test scores, which often reflect family income more than school quality. Repit takes a different approach.

We evaluate schools based on factors that research shows actually impact educational outcomes:

  • Class Size — Smaller classes mean more individual attention
  • School Funding — Resources available for programs, staff, and facilities
  • Community Factors — Neighborhood characteristics that influence student success
  • School Environment — Size, type, and structure

Scores are updated annually using federal education data.
