Market Analysis: 94403 San Mateo

ZIP 94403 in San Mateo, CA carries a healthy set of headwinds. Home values near $1.8M and rents of $3,746/mo sit inside a market where underwriting has to be tight.

The 94403 ZIP can work — but only with a tight operating hand. Remote landlords and passive investors tend to struggle here more than the underwriting suggests.

Nearby ZIPs in San Mateo have seen price recovery that 94403 has not matched. San Mateo County data supports the view that the spread is structural rather than temporary.

The 94403 ZIP's population of 43,459 has faced economic pressure over the last decade. That pressure shows up in rent delinquency patterns that reflects the need for careful underwriting.

Experienced landlords with local relationships tend to find 94403 workable. Turnkey investors from out of state usually find the numbers do not hold up in practice.

Negative Leverage — IRR / Tax Play Cap Rate: 1.6%  |  30yr Rate: 6.8%
Leverage reduces cash returns at current rates.

The current 30-yr mortgage rate (6.8%) exceeds the estimated cap rate (1.6%). 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.
