Stay or Move? Forever Home FAQ for San Diego Owners

Updated October 2026 · Rudy Flores

After years in one house, the next step could be a remodel, a smaller place, a rental or a plan to hand the home on. These answers lay out the rules and numbers behind each path, so your talks with an attorney, CPA or tax adviser start on solid ground.

Staying Put or Moving On

How do I decide whether to stay or move?

Put both paths in numbers side by side. The site’s long-term cost of owning calculator adds up property tax, insurance and upkeep year by year if you stay. The downsizing calculator shows the cash a move could free up and how your monthly costs would change. You can send either estimate to Rudy for a personal version, with no pressure.

What changes help a home work for the long run?

Start with the features that make everyday routines easier. A no-step entry, a bedroom and full bath on the main floor, wide doorways and lever handles all help. In the bath, a low-threshold shower with a seat and wall blocking for future grab bars make later changes easy. Many occupational therapists and contractors with the Certified Aging-in-Place Specialist (CAPS) credential can assess a home and suggest changes.

Will a remodel or an ADU raise my property tax?

It may. California may reassess new construction, so an addition or an accessory dwelling unit (ADU) could add to your assessed value. Ask the county assessor how a specific project would be treated before you build. The site’s ADU return estimator weighs a unit’s cost against the rent it could bring in.

What big costs come with staying in an older home?

The big replacements. Based on InterNACHI’s chart, the site’s maintenance planner puts tank water heaters at about 6 to 12 years, asphalt shingles at about 20 to 30 and exterior paint at about 7 to 10. Turning each item’s age into a monthly set-aside spreads the cost over time. On the tax side, the county assessor’s site points owners 62 and over who meet other requirements to the State Controller’s Property Tax Postponement Program.

Is there a better month to sell a home I’ve owned for years?

Your own plans often matter more than the month. Averaged over past years, San Diego sale prices have run about 3.5% above their yearly trend in June and about 3.2% below it in January. That is history, not a forecast. The disclosure forms ask what you know about the home, including work done without permits, so gather permits and warranties early.

Prop 19 and Your Property Tax Base

Who can move a property tax base to a new home under Prop 19?

Three groups qualify: homeowners who are 55 or older, those who are severely and permanently disabled, and victims of a wildfire or a natural disaster declared by the Governor. You must meet one of these on the date the original home sells, and both homes must be your principal residence. The replacement can be anywhere in California. Owners who qualify by age or disability can use the transfer up to three times.

How long do I have to buy the replacement home?

The replacement has to be bought or newly built within two years of the sale, either before or after it. If you buy first, you pay tax on the new home’s full market value until the old one sells, and that period is not refunded. The claim goes to the assessor in the county where the new home sits, after the sale and the purchase both close and you live in the new home. The deadline is three years from buying the new home or finishing its construction.

What if the new home costs more than the one I sell?

Any value above the state’s limit is added to the base you carry over. The limit is 100% of the old home’s market value if you buy or build before you sell, 105% in the first year after the sale and 110% in the second year. In a state example, selling a $400,000 home and buying a $600,000 one in the first year adds $180,000 to a $100,000 base, for $280,000. Your tax bill can still differ, because tax rates vary from area to area.

Can my children keep my property tax base if they inherit the home?

Sometimes, under narrower rules for transfers on or after February 16, 2021. The base can carry over only for the parent’s principal residence or a qualifying farm, and the child must make the home their own principal residence. The child files for the homeowners’ exemption within one year, and the BOE-19-P claim within three years of the transfer or before any transfer to a third party, whichever is first. A grandchild can qualify only if their parents are deceased on the date of transfer.

Is there a value limit on a parent-child transfer?

Yes. If the home’s market value on the transfer date is more than the parent’s factored base year value plus an adjusted $1 million, the excess is added to that base. The adjusted amount is $1,044,586 for transfers from February 16, 2025 through February 15, 2027, and the state updates it every two years. Apart from a qualifying farm, rentals and other property that is not the parent’s principal residence no longer qualify.

Trusts, Heirs and Renting It Out

Does putting my home in a living trust trigger a reassessment?

Generally, no. The San Diego County Assessor says putting a home in a revocable trust, or one where the benefit stays with you, is generally not a change in ownership. A revocable trust, often called a living trust, can be changed or canceled during its term. A reassessment can come up later, when the home passes to the next owner, unless an exclusion applies.

How does a trust help pass on a home?

A living trust names a successor trustee to manage your assets for the beneficiaries you choose. If you have put the home into the trust, the California courts’ self-help site says it should go to those beneficiaries without probate court. A home in a parent’s trust may still qualify for the parent-child exclusion, and the county asks for the trust documents with the claim. The courts’ site adds that living trusts are complicated, so an estate-planning attorney usually helps set one up.

Is there another way to pass on a home without probate?

The courts’ self-help site describes a transfer on death (TOD) deed, which names who receives the property when you die, without probate court. You fill out the form, have it notarized and record it with the County Recorder. You can revoke it if you change your mind. An estate-planning attorney can say whether a TOD deed, a trust or a will fits your plans.

Should I rent out my home instead of selling it?

Run the numbers both ways first. A home held for years may carry a Proposition 13 tax bill well below what a new buyer would pay, and that changes the rental math. The site’s keep-or-sell calculator compares the first-year return of renting it out with selling and investing the cash. It leaves out income tax on rent and the work of being a landlord, such as repairs, vacancies and local rent and notice rules.

Does renting the home first change the tax on a later sale?

It can, since the federal exclusion of up to $250,000 of gain on a single return, or $500,000 on a joint return, has a use test. You generally must have owned the home and used it as your main home for at least 2 of the 5 years before the sale. Years of renting can shrink the exclusion, and depreciation claimed on a rental changes the result. California taxes the gain as ordinary income, so ask a CPA to work through your own dates.
