How to Keep Your Low Property Taxes When You Sell: A Woodland Hills Guide to Prop 19

By Jason Franklin | July 10, 2026

If you've owned your Woodland Hills home since the '80s or '90s, your property tax bill probably looks almost embarrassingly small compared to what a neighbor who bought last year is paying.

That's Prop 13 at work — and it's one of the most powerful financial benefits a California homeowner can hold. Your assessed value is locked to your original purchase price, with a maximum 2% annual increase, no matter how much the market has run up since then.

But there's a catch. If you sell and buy something new, you lose your Prop 13 base. Your new home gets reassessed at the current purchase price. On a $1.2 million replacement home in today's market, that can triple your annual property tax bill overnight.

The result is what most longtime West San Fernando Valley homeowners know as the golden handcuff. People who'd love to downsize, move closer to grandkids, or trade into a single-story that's easier to manage are staying put — not because they want to, but because selling feels financially punishing.

Prop 19 was built to change that. And for most homeowners who qualify, it changes the math significantly. Here's how it works.

What Prop 19 Changed — and What It Replaced

Before Prop 19 took effect on February 16, 2021, California homeowners had two limited options under Props 60 and 90. You could transfer your tax base once, but only to a home of equal or lesser value, and only if you stayed in the same county or moved to one of the handful of counties that had voluntarily opted in.

Prop 19 expanded this considerably. Under the new rules:

• You can transfer your tax base to any county in California
• To a home of any value — with an adjustment if you buy up
• Up to three times in your lifetime
• Starting at age 55 — you don't have to wait until full retirement

For a Woodland Hills homeowner sitting on a home they've held for 25 to 35 years, this is a meaningful unlock. Moves that didn't pencil out before often do now.

How the Transfer Actually Works

The formula depends on one key question: does your replacement home cost more or less than the home you're selling?

If you downsize or move to a home of equal or lesser value

Your full Prop 13 assessed value transfers. No adjustment. Your tax base carries over exactly as it was.

If you buy a more expensive replacement home

Prop 19 still helps — you just pay the difference. Your new assessed value equals your old Prop 13 base plus the gap between the two sale prices.

The protection Prop 19 provides scales with how long you've held your home and how much the market has appreciated. The longer you've been in place, the more valuable the transfer.

Who Qualifies

Prop 19's base-year transfer benefit is available to three groups:

• Homeowners age 55 or older — only one spouse or co-owner on title needs to meet the age requirement
• Severely disabled individuals — regardless of age
• Wildfire or declared disaster victims — if your original home was substantially damaged or destroyed

The home you're selling must be your primary residence at the time of sale. Investment properties, vacation homes, and rentals don't qualify for this benefit. And as noted, you can use the transfer up to three times in your lifetime.

If you transferred your tax base once under the old Props 60 or 90 rules, that does not count against your three-transfer limit under Prop 19. The counter resets.

The Two-Year Window — and How Timing Works

The most common practical question I hear from clients thinking through this: Do I have to sell first, or can I buy the replacement home first?

Prop 19 gives you flexibility in both directions. The two-year window runs from whichever event happens first:

• Sell first, buy later — you have up to two years from your sale to purchase the replacement
• Buy first, sell later — you have up to two years from your purchase to sell the original

Either way, you must file your claim with the LA County Assessor within three years of purchasing the replacement home. The form is BOE-19-P (for age 55+ transfers). You can download it directly from the LA County Assessor at assessor.lacounty.gov.

If you buy before you sell, your new home will be assessed at current market value initially. Once you sell the original and file the BOE-19-P claim, the Assessor retroactively adjusts your assessed value and refunds any overpaid taxes. Most claims in LA County are processed within four to eight weeks.

A Few Things People Get Wrong

Prop 19 is not the parent-to-child exclusion. The old parent-to-child property tax exclusion — where parents could pass a home to their kids at the original assessed value — was dramatically restricted by Prop 19. Many families who thought they could inherit a rental property at grandma's tax base were surprised to find out the rules changed. If you're planning an estate strategy involving a California property, get a tax attorney involved. Don't assume the old rules still apply.

Prop 19 doesn't affect capital gains. These are two completely separate tax systems. If your Woodland Hills home has appreciated significantly since you bought it, you may have a capital gains event when you sell — and California taxes capital gains as ordinary income, with no preferential rate. The federal primary residence exclusion ($250,000 per person, $500,000 married) applies, but many longtime SFV homeowners have gains well above those thresholds. Talk with a CPA before you list.

You have to actually move in. Your replacement home must become your primary residence — you can't use Prop 19 to transfer your tax base to an investment property or a vacation home.
