How This Calculator Works

This tool uses California's standard 1.1% effective property tax rate (varies by county between approximately 1.0% and 1.25%). It applies Proposition 19 rules: if you make the property your primary residence, the parent's assessed value is preserved up to a $1 million value cap on appreciation. If you don't make it your primary residence, the property is reassessed to current market value.

The Big Picture

For most heirs who don't intend to live in the inherited property, Prop 19 makes selling significantly more attractive than keeping. The combination of avoiding reassessed property taxes and capturing the stepped-up basis tax benefit usually produces tens of thousands of dollars in better outcomes — particularly over 5+ years of holding.
