Prop 19 base-value transfer (California)

Owners 55+ (or disabled, or wildfire victims) can carry their property tax base to a replacement home anywhere in California, up to three times.

New taxable value
Without Prop 19
Approx. yearly tax saving at 1.1%

If the new home costs more than the sale price, the difference is added to your base. Timing rules apply (buy within two years) and the replacement price limit rises slightly if you buy after you sell. Confirm with your county assessor.
