How Prop 19 changed California real estate: moving without the property-tax shock

For a long time, the biggest reason homeowners stayed put — even when they wanted to downsize or move — was the property-tax hit. The moment you sold and moved, your taxes reset to the new home's purchase price. That was the math. Now it isn't. California's Proposition 19 opened up a path to move without that tax shock.

01 The core idea: bring your low tax basis with you

If you're 55 or older, you can sell your current home and move anywhere in California — and bring your existing (low) property-tax basis with you to the new property.

Even if the new home is more expensive than your old one, only the difference gets factored into your new tax basis. The low-tax benefit you've built up stays largely intact.

02 Why this is an opportunity for buyers

Because of this law, senior homeowners who were locked in place by the tax penalty are now starting to list. That's good for them — and great for the young families and first-time buyers who have been priced out of well-loved neighborhoods because nobody was selling.
