Prop 19: How Homeowners 55+ Can Move Anywhere in California and Keep Their Low Property Taxes
Quick answer
Under Proposition 19, California homeowners who are 55 or older (or severely disabled, or displaced by wildfire or disaster) can sell their primary residence, buy a replacement primary residence anywhere in the state, and transfer their old home's low taxable value to the new home — up to three times. If the new home costs more than the old one sold for, the difference is added on top of the transferred value. The claim is filed with the county assessor, and the purchase generally must happen within two years of the sale.
One of the biggest reasons longtime California homeowners stay put — even in a house that no longer fits — is the property-tax bill. After twenty or thirty years under Prop 13, many pay taxes on an assessed value far below what the home is worth today, and buying elsewhere used to mean a painful reassessment at full price. Proposition 19 changed that. If you're 55 or older, you can sell your home, buy a replacement anywhere in California, and bring your old taxable value with you. Here's how it works, in plain terms, with a quick estimator to see what it could mean for your tax bill.
Why Your Taxable Value Is Probably Far Below Market Value
Since 1978, Prop 13 has limited how fast a home's assessed value can grow — no more than 2% per year, no matter what the market does. So a home bought in Downey or Whittier in the 1990s for $180,000 might carry a taxable value around $300,000 today, even if it would sell for $850,000. Property tax runs roughly 1% of assessed value plus local add-ons (about 1.1% is a common average), so that gap is worth thousands of dollars every year. Losing it used to be the price of moving. Prop 19 lets homeowners 55 and older keep it.
Exact tax rates vary by county and by the local bonds and assessments on your bill.
What Prop 19 Lets You Do
Proposition 19, in effect since April 1, 2021, lets you transfer your home's taxable value when you sell your primary residence and buy another primary residence in California. The basics:
- You qualify if you're 55 or older when you sell (also available if you're severely disabled, or lost your home in a wildfire or governor-declared disaster)
- The new home can be anywhere in California — any county, no reciprocity lists like the old rules
- The new home can cost more than the old one; you no longer have to buy 'equal or lesser value' to qualify
- Homeowners 55+ can use the transfer up to three times in a lifetime
- You generally must buy (or finish building) the replacement home within two years of selling
Both homes must be your primary residence — the transfer doesn't apply to rentals or vacation homes.
The Math: What Your New Taxable Value Would Be
The rule is simpler than it sounds. If the new home costs the same or less than what your old home sold for, your old taxable value simply moves with you. If the new home costs more, the extra amount gets added on top. Say your taxable value is $300,000, you sell for $850,000, and you buy for $700,000 — your new taxable value stays $300,000. Buy for $950,000 instead, and the $100,000 premium is added: your new taxable value is $400,000 — still far below the $950,000 a new buyer would be assessed at. Try your own numbers below.
How to Claim It
The transfer is not automatic — you file a claim with the assessor in the county where the new home is. The usual steps:
- Close on the sale of your current home and the purchase of the replacement (in either order, within the two-year window)
- Get the claim form — most counties use form BOE-19-B, available from the county assessor's office or website
- File the claim with the assessor in the county of your NEW home
- The assessor verifies eligibility and recalculates the new home's taxable value; any refund or corrected bill follows
File promptly — claiming within three years of the purchase generally preserves full retroactive benefit. Your county assessor's office can confirm deadlines for your situation.
What Prop 19 Changed for Inherited Homes
The same measure also narrowed the old parent-child exclusion, which matters for estate planning. Since February 2021, a child who inherits a home generally keeps the parent's low taxable value only if the home was the parent's primary residence and the child moves in and makes it their own primary residence — and even then, only up to a value limit (the exclusion covers the old taxable value plus a cap adjusted over time; the excess is reassessed). Inherited rentals and second homes are now reassessed at market value. Families counting on passing a low tax base to their children should talk this through with an estate-planning professional.
This is general education, not legal or tax advice — the inherited-property rules have important details that depend on your family's facts.
Staying vs. Moving: Where a Reverse Mortgage Fits
Prop 19 takes one big obstacle off the table, but the stay-or-move decision is still personal. In our conversations with homeowners 62 and older, it usually comes down to two workable paths:
- Stay and adapt: a reverse mortgage (HECM) can pay off an existing mortgage, fund in-home care or safety updates, and let you age in place in the neighborhood you know — with no required monthly mortgage payment while you keep up taxes, insurance, and upkeep
- Move with both tools: sell, transfer your tax base under Prop 19, and use a HECM for Purchase to buy the replacement home — often putting roughly half down and financing the rest with no required monthly mortgage payment, keeping more cash from the sale in reserve
Neither path is right for everyone, and a reverse mortgage is a significant decision. A free, no-pressure conversation with real numbers — in English or Spanish — is the best way to compare them.
Talk It Through Before You Decide
If the property-tax question has been keeping you in a home that no longer fits — too many stairs, too far from family, too much yard — it's worth seeing the actual numbers. Miguel A. Vazquez (NMLS #401212) can walk you through what a move under Prop 19 could look like next to staying put with a reverse mortgage, and your county assessor or tax professional can confirm the tax side. No pressure, no obligation — just a clear picture.
Key takeaways
- Homeowners 55+ can sell, buy anywhere in California, and transfer their low taxable value — up to three times.
- If the new home costs more, only the difference above your old sale price is added to the transferred value.
- The purchase generally must happen within two years of the sale, and you must file a claim with the county assessor.
- Prop 19 also narrowed the parent-child exclusion for inherited homes — worth a conversation with an estate planner.
- This is education, not tax advice — confirm your numbers with your county assessor or a tax professional.
Frequently asked questions
Who qualifies for a Prop 19 base transfer?
Homeowners who are 55 or older when their primary residence sells, homeowners who are severely disabled, and homeowners displaced by wildfire or a governor-declared disaster. Both the home you sell and the home you buy must be your primary residence, and the purchase generally must happen within two years of the sale.
Can I move to any county in California?
Yes. Prop 19 removed the old county-by-county restrictions — the replacement home can be anywhere in the state. Before Prop 19, transfers only worked within your county or into a short list of counties that accepted them.
What if my new home costs more than my old one sold for?
You can still transfer your base. The amount the new home costs above your old home's sale price is added to your transferred taxable value. Example: taxable value $300,000, sale at $850,000, purchase at $950,000 — new taxable value is $400,000, not $950,000.
How many times can I use the Prop 19 transfer?
Homeowners 55 and older (and severely disabled homeowners) can use it up to three times. Transfers for wildfire or disaster victims are not limited to three.
Does Prop 19 work together with a reverse mortgage?
They can complement each other. Prop 19 handles the property-tax side of a move; a HECM for Purchase can handle the financing side — buying the replacement home with roughly half down and no required monthly mortgage payment, as long as you live in the home and keep up property taxes, insurance, and maintenance. Whether that combination fits depends on your situation.
Is the tax-base transfer automatic when I buy the new home?
No. You must file a claim (typically form BOE-19-B) with the assessor in the county where your new home is. Until the claim is processed, the new home is billed at its purchase-price assessment, with a corrected bill or refund after approval.
