The California Property Tax Problem
Prop 13 protects you.
But assessors still get it wrong.
Your county assessor uses mass appraisal formulas to value your home. They don't visit your property. They don't see the deferred maintenance, the outdated systems, or the market shifts in your neighborhood.
They rely on data and algorithms. And when values are rising, they often overvalue.
That's why up to 60% of California properties may be over-assessed. But fewer than 5% of homeowners ever file an appeal.
