Losing a parent or loved one is hard enough without a mortgage statement landing on the kitchen table. The good news: federal law usually lets heirs keep paying the existing loan without it being called due. Here is how that works in California, and how Prop 19 can change the property-tax picture.
Garn-St. Germain: why the lender usually can't call the loan due
Most mortgages contain a due-on-sale clause letting the lender demand full payoff if the property transfers. But the federal Garn-St. Germain Depository Institutions Act lists exceptions where a lender cannot enforce that clause. Two key ones: a transfer to a relative on the borrower's death, and a transfer to a relative who will occupy the property.
In plain terms, if you inherit a parent's home and move in (or already qualify under one of the listed exceptions), the lender generally must let you take over the existing loan and keep paying it under its current terms—you do not have to refinance just because the owner died.
"Assuming" the loan as an heir—what to actually do
Practically, you (or the estate) should contact the loan servicer, identify yourself as a successor in interest, and provide the death certificate and proof you inherited (a will, trust, court order, or recorded deed). Federal mortgage-servicing rules require servicers to work with confirmed successors in interest—giving you loan information and letting you assume payment responsibility. Keep the loan current while paperwork is processed.
Note: keeping up the payments is what protects the home. Garn-St. Germain stops the lender from calling the loan due, but it does not forgive the debt.
Due-on-sale exceptions in plain English
The most common Garn-St. Germain exceptions that help families include: transfer to a relative resulting from the borrower's death; transfer to a spouse or children; transfer in a divorce or legal separation where a spouse keeps the home; and transfers into the borrower's own living trust where they remain a beneficiary. If your situation fits one of these, the lender generally cannot use the transfer to accelerate the loan—confirm the specifics with the servicer and an attorney.
Prop 19: the property-tax surprise to plan for
Even when you keep the loan, Proposition 19 may change the property taxes. Before Prop 19, children could inherit a parent's low Prop 13 tax basis fairly broadly. Since February 16, 2021, the parent-child exclusion is much narrower:
- It applies only to the parent's primary residence (or a family farm)—not rentals, vacation homes, or investment property.
- The child must make it their own primary residence, generally moving in within one year and filing for the homeowners' (or disabled veterans') exemption.
- There is a value cap: the protected (taxable) value is the parent's factored base-year value plus an inflation-adjusted exclusion amount ($1,044,586 for transfers 2/16/2025–2/15/2027). Value above that is added to the new assessment.
If you will not live there, expect a reassessment to market value—which can sharply raise the tax bill. Verify the current cap and rules with your County Assessor before deciding to keep or sell.
Keep it, rent it, or sell it—a quick framework
Move in: you may keep both the existing loan (via Garn-St. Germain) and, within the cap, a favorable tax basis (via Prop 19). Rent or hold it: the loan can usually stay, but expect Prop 19 reassessment to market value. Sell: heirs often benefit from a stepped-up basis to the date-of-death value, which can reduce capital-gains tax on a sale—confirm with a CPA. Brian can value the home and model each path with you.

Frequently Asked Questions
Can the bank force me to pay off the mortgage because the owner died?
Generally no, if you are a relative who inherits and the Garn-St. Germain exceptions apply. The lender usually cannot enforce the due-on-sale clause, so you can keep paying the existing loan. You must still keep payments current and notify the servicer.
Do I have to refinance the inherited mortgage into my name?
Not necessarily. Federal servicing rules let a confirmed successor in interest assume responsibility for the existing loan. You may choose to refinance for a better rate, but inheritance alone does not require it.
Will my property taxes go up after I inherit?
Possibly. Under Prop 19, the home is reassessed to market value unless it was your parent's primary residence, you move in as your own primary residence within one year and file the homeowners' exemption, and the value stays within the cap. Confirm the current cap with your County Assessor.
What is the Prop 19 value cap right now?
For transfers between February 16, 2025 and February 15, 2027, the exclusion amount is $1,044,586 on top of the parent's factored base-year value. It is adjusted for inflation every two years, so verify the figure for your transfer date.
What if several siblings inherit the home together?
Only one sibling generally needs to live in it as a primary residence to claim the primary-residence exclusion, and the family must file the proper exemption. The ownership and occupancy rules are detailed, so review them with an attorney or the Assessor.
Is there a tax benefit if we just sell the inherited home?
Often yes. Inherited property typically receives a stepped-up cost basis to the date-of-death value, which can significantly reduce capital-gains tax when you sell. A CPA can confirm the basis and any gain.
