Keep the house or sell it: under Prop 19, the honest answer comes down to one question. Are you actually going to live there? If you move in and make it your principal residence within a year and file the homeowners’ exemption, you may hold onto your parent’s low property-tax base, but only up to a cap. If you won’t live there, the county fully reassesses the home to market value, and selling soon after the death often erases most or all of the capital gains tax because of the step-up in basis. The cap for transfers on or after 2/16/2025 is the factored base-year value plus $1,044,586 (current as of 2026). This is a math problem before it’s a feelings problem.
Before anything else, clear up the biggest confusion I hear: Prop 19 is a property-tax reassessment rule. It is not an inheritance tax. California has no estate tax and no inheritance tax (Rev. & Tax. Code §13301). Nobody is taxing you for inheriting the house. What’s at stake is how much property tax you’ll pay going forward, and that’s it.
What Prop 19 actually does to an inherited house
Prop 19 changed the rules for keeping a parent’s low property-tax assessment when their house passes to a child, effective for transfers on or after February 16, 2021 (Cal. Const. art. XIII A §2.1; Rev. & Tax. Code §63.2). To keep that low base-year value, the child has to make the home their principal residence within one year of the transfer and file for the homeowners’ (or disabled-veterans’) exemption. Miss either step and the house is reassessed to current market value. On a home your parent bought decades ago, that can multiply the property-tax bill several times over.
Even if you do move in, the break isn’t unlimited. The exclusion is capped at the home’s factored base-year value plus $1,044,586 for transfers occurring February 16, 2025 through February 15, 2027 (BOE News Release NR 25-02; the prior figure was $1,022,600). If the home’s current market value exceeds the sum of the factored base-year value and that $1,044,586 add-on, the excess is added to the taxable value. So a very valuable house gets only a partial benefit even when you live in it. The cap is indexed every two years, so confirm the then-current figure for your transfer date.
One correction worth flagging, because AI answers get it wrong constantly: the old Proposition 58 blanket parent-child exclusion (former Rev. & Tax. Code §63.1) is repealed for transfers after February 15, 2021. Anyone quoting Prop 58 as current law, or telling you any parent-child transfer keeps the low value with no move-in requirement, is working from dead law.
Does a living trust protect me from Prop 19 reassessment?
No. A revocable living trust does not protect an inherited house from Prop 19 reassessment. This is the myth I most want to kill on this page. Reassessment turns on the parent-child exclusion rules and how the child uses the home, not on whether a trust holds the title. A trust is a probate-avoidance and incapacity tool. It is not a Prop 19 shield.
If someone tells you “put the house in a trust and Prop 19 won’t touch it,” they are either confused or selling something. A trust controls how the house passes: privately, without probate, to the people you named. It does not control whether the county reassesses it. The reassessment question is decided by the same rules whether the house comes through a trust, a will, or a beneficiary deed: did a child move in within a year and claim the homeowners’ exemption, and is the value under the cap? Don’t let anyone sell you a trust as a tax dodge it isn’t.
Do I owe capital gains tax when I sell the inherited house?
Usually little or none if you sell soon after the death. This is the part most people get backwards. When you inherit a house, its tax basis generally resets to the fair market value on the date of death (IRC §1014(a)). That’s the step-up in basis. Capital gains is then measured only against that stepped-up value, not what your parent originally paid.
Here’s why that matters. Say your mother bought her Ventura County home in 1985 for $120,000, and it’s worth $850,000 when she dies. Had she sold during her life, she’d have faced capital gains on roughly $730,000 of appreciation. Because you inherited it, your basis steps up to $850,000. Sell a few months later for $860,000 and your taxable gain is about $10,000, not $740,000. Sell right at $850,000 and there’s essentially no gain at all.
People confuse this with an “inheritance tax.” There isn’t one in California. The step-up in basis is an income-tax rule about capital gains (IRC §1014(a)), and it generally works in your favor when you sell shortly after a death. For a married couple, California’s community-property rules give an even bigger break: both spouses’ halves step up to full fair market value when the first spouse dies (IRC §1014(b)(6)). The longer you hold the house after inheriting, the more new appreciation builds up above the stepped-up basis, and that future gain is taxable when you eventually sell.
So: keep it or sell it?
Frame it as a real trade-off, because that’s what it is. Neither choice is “smart” or “dumb” in the abstract. They fit different lives.
| Keep the house | Sell soon after death | |
|---|---|---|
| Property tax | Possible low Prop 19 base, but only if you move in within a year, claim the homeowners’ exemption, and stay under the cap (factored base value + $1,044,586) | Not your concern; the buyer gets reassessed at market |
| Capital gains | Deferred, but future appreciation above the stepped-up basis will be taxable later | Step-up in basis often erases most or all gain when you sell near date-of-death value (IRC §1014) |
| Best fit | You’ll genuinely live in the family home | You won’t live there, or heirs want cash, or no one wants the upkeep |
| Watch out for | The cap on high-value homes; losing the low base if you later move out (the exclusion requires ongoing principal-residence use) | Timing: gain grows the longer you wait to sell |
I’ll explain the tax and title mechanics so you can decide with clear eyes. What I won’t do is tell you what to do with the proceeds, or steer you toward selling or keeping based on anything but your own goals. That’s your call.
Do all the heirs have to agree to sell the inherited property?
It depends on how the house is held. If the house is in a trust, the trustee (the person your parent named to wind up the estate) usually has the authority to sell it, and the beneficiaries don’t all have to sign the deed. The trust document controls, and most trusts give the trustee broad power to sell real property to carry out the distribution. The trustee still owes every beneficiary a duty of fairness and has to account for the proceeds, but selling doesn’t require a unanimous vote.
If the house passed to several people as co-owners outright (say, three siblings each taking a one-third interest by deed), then the picture changes. Now everyone on title generally has to agree to sell, and a single holdout can stall the whole thing. When agreement breaks down, the legal tool is a partition action, where a court can force a sale and divide the money. It’s slow, costly, and hard on a family. (For more on the trustee’s role here, see successor trustee duties in California.)
The classic fight: one sibling wants to keep the family home, the others want their inheritance in cash. The keeper has to buy the others out at fair value. If they can’t fund the buyout, the house usually has to be sold so everyone gets their share. None of this is about Prop 19. It’s about co-ownership, and it lands on the same kitchen table at the same time.
What about the mortgage or reverse mortgage?
The debt doesn’t die with the owner. It stays attached to the house. A regular mortgage generally continues after death, and federal law usually lets a family member who inherits the home take over the payments or assume the loan without the lender calling it due (the federal Garn-St Germain Act, 12 U.S.C. §1701j-3, protects certain transfers on death of a borrower). You keep paying; the house stays yours to keep or sell.
A reverse mortgage is different and catches families off guard. It typically becomes due when the borrower dies. The heirs usually get a limited window to repay it, refinance into a regular loan, or sell the house to pay it off, often by paying the lesser of the loan balance or 95% of the home’s appraised value (the rule for the federally insured HECM reverse mortgage). If the loan balance is close to the home’s value, “keeping it” may not pencil out. This is worth pinning down early, because the clock starts at death and the lender’s deadlines are real.
The honest caveat
The step-up in basis and the Prop 19 break can pull you in opposite directions, and no trust or deed trick makes both problems disappear at once. Moving in to capture the low property-tax base means giving up the clean capital-gains exit you’d get from selling soon after the death. Selling to lock in the step-up means walking away from the low tax base. That tension is real, it’s not a loophole anyone can engineer around, and the right answer is whichever one fits the life you’re actually going to live, not the one a salesperson profits from.

Frequently asked questions
Should I keep my mom’s house or sell it under Prop 19?
It depends on whether you’ll actually live there. To keep your mom’s low Prop 19 property-tax base, you must make the house your principal residence within one year and file for the homeowners’ exemption, and even then the exclusion is capped at the factored base-year value plus $1,044,586 for transfers 2/16/2025-2/15/2027 (Rev. & Tax. Code §63.2; BOE NR 25-02). If you won’t live there, the house is fully reassessed, and selling soon after death often wipes out most capital gains thanks to the step-up in basis (IRC §1014). Run both numbers first.
Do all the heirs have to agree to sell the inherited property?
If the house is in a trust, the trustee usually has authority to sell it and the beneficiaries don’t all have to sign: the trust document controls. If the house passed to several people as co-owners outright, then generally everyone on title must agree, and one holdout can stall the sale. The common flashpoint is one sibling wanting to keep the house while the others want cash.
Does a living trust protect me from Prop 19 reassessment?
No. A revocable living trust does not shield an inherited house from Prop 19 reassessment (Cal. Const. art. XIII A §2.1). Reassessment turns on the parent-child exclusion rules, namely whether the child makes the home their principal residence within a year and files for the homeowners’ exemption, not on whether a trust holds title. A trust helps you avoid probate; it is not a Prop 19 workaround.
Is Proposition 58 still the law for parent-child transfers?
No. The old Prop 58 blanket exclusion (former Rev. & Tax. Code §63.1) is repealed for transfers after February 15, 2021. Prop 19 replaced it (Cal. Const. art. XIII A §2.1; Rev. & Tax. Code §63.2): the child now must occupy the home as a principal residence within a year and file the homeowners’ exemption, and the shielded value is capped. Any answer citing Prop 58 as current is out of date.
Do I owe capital gains tax when I sell an inherited house in California?
Usually little or none if you sell soon after the death, because of the step-up in basis (IRC §1014(a)). An inherited home’s tax basis generally resets to its fair market value on the date of death, so capital gains is measured only on appreciation after that date. A married couple gets a full double step-up on community property (IRC §1014(b)(6)). California has neither an inheritance tax nor an estate tax (Rev. & Tax. Code §13301).
