California homeowners sit on massive equity thanks to decades of appreciation and Prop 13's low tax base. The average CA homeowner has over $400,000 in home equity. But accessing that equity — or transferring it — comes with unique CA rules. Proposition 19 (2021) changed parent-to-child property transfers: inherited homes used as rentals now get reassessed to market value, while primary residence transfers get a $1 million cap on the base-year value exclusion. This calculator shows your equity position and Prop 19 transfer implications.

Frequently Asked Questions
How does Proposition 19 affect inherited property in California?
Since Feb 2021, inherited property used as a rental or second home gets fully reassessed to market value. Only inherited primary residences qualify for the parent-child exclusion, and it's limited to a $1M cap above the transferred base value.
How much equity does the average California homeowner have?
The average CA homeowner has over $400,000 in home equity, with Bay Area homeowners averaging $700,000+. This is largely due to strong appreciation combined with Prop 13's low assessed values.
Can I get a HELOC in California?
Yes. Most CA lenders offer HELOCs up to 80-85% combined loan-to-value. On an $800K home with a $400K mortgage, you could access up to $240K-$280K via HELOC. Rates are typically Prime + 0-2%.
What happens to Prop 13 base when I sell?
When you sell, the new buyer's Prop 13 base resets to the purchase price. Your accumulated low-tax benefit doesn't transfer (except under Prop 19 for qualifying transfers). This creates 'lock-in' — an incentive to never sell.
Should I do a cash-out refinance or HELOC in California?
HELOCs offer flexibility (draw as needed, interest-only payments) while cash-out refis give a fixed rate on a lump sum. In CA's high-equity market, HELOCs are popular for renovations while cash-out refis work better for debt consolidation.
