HOME TOOLS · SEPTEMBER 2026

Updated September 2026 · Rudy Flores

California reassesses a home at its purchase price. Enter a price and any special taxes to see an estimated bill, and how it could change as the assessed value grows.

In San Diego County, a purchase near $902K would carry roughly $10,372 a year in property tax at about 1.15%, or $864 a month, before any special taxes.

Set by Proposition 13 at 1% of assessed value.
Varies by address. The county tax bill lists the exact charges.
Common in newer communities. Ask for the exact amount.
California’s exemption reduces the assessed value of a home you live in by $7,000. Use 0 for a second home or rental.
To see how much the reassessment could change it.
