Proposition 19 Series – Part 3: Yes, You Can Buy a More Expensive Home and Still Transfer Your Tax Base

Proposition 19 Series – Part 3: Yes, You Can Buy a More Expensive Home and Still Transfer Your Tax Base

If you've been following our Proposition 19 series, you've learned that homeowners over age 55 can transfer their property tax base to a replacement home anywhere in California. But one of the biggest misconceptions I hear is:

"Nancy, that's great if I'm downsizing. But what if I want to buy a more expensive home?"

Good news—you can still benefit from Proposition 19. In fact, many homeowners are surprised to learn that they can purchase a home that costs more than the one they're selling and still receive substantial property tax savings. Let's walk through an example.

The Scenario

Let’s say:

  • You are over 55 years old.

  • You sell your current home for $1,600,000.

  • Your current assessed value is $750,000.

  • You purchase a replacement home for $2,500,000.

How the Calculation Works

When the replacement property costs more than the home you sold, California allows you to transfer your existing tax base and then add the difference between the two sales prices.

Here’s the math:

Replacement Home Purchase Price: $2,500,000

Original Home Sale Price: $1,600,000

Difference: $900,000

Now add that difference to your current assessed value:

Current Assessed Value: $750,000

Plus Difference: $900,000

New Transferred Assessed Value: $1,650,000

Instead of being assessed at the full purchase price of $2,500,000, your new home’s assessed value would be approximately $1,650,000.

What Does That Mean in Real Dollars?

Using a rough California property tax rate of about 1.25%:

  • Taxable value at $2,500,000 = approximately $31,250 annually

  • Taxable value at $1,650,000 = approximately $20,625 annually

That’s a savings of roughly $10,625 per year.

And those savings continue year after year.

Not bad for filling out a little paperwork.

Why This Matters

Many homeowners stay in homes that no longer fit their lifestyle because they're afraid of the property tax consequences. Maybe the grandchildren have arrived and you need more space. Maybe you're moving closer to family. Maybe you've finally decided that a home with a view is worth the splurge.

Whatever the reason, Proposition 19 gives qualifying homeowners flexibility that simply didn't exist before. You don't have to limit yourself to buying a less expensive property in order to receive tax benefits.

A Few Important Rules

To qualify:

  • You must be at least 55 years old (or otherwise meet Proposition 19 eligibility requirements).

  • The replacement property must become your principal residence.

  • The purchase or construction of the replacement property must occur within two years of the sale of the original home.

  • You must file the required claim with the county assessor.

As always, individual situations can vary, so it's wise to consult with your tax professional or estate planning advisor.

Final Thoughts

One of the most rewarding conversations I have with clients is when they realize they have more options than they thought. Many homeowners have spent decades building equity in their homes while keeping a wonderfully low property tax basis. Proposition 19 allows many of them to move without completely losing that advantage.

So if you've been eyeing that dream home and telling yourself, "I can't afford the property taxes," it may be time to run the numbers. You might discover that California has actually given you a pretty valuable moving coupon. And unlike the coupons I find in my kitchen drawer six months after they expire, this one could save you thousands of dollars every year.
