Most people facing this are an adult child, a surviving spouse or a sibling who has just learned that the family home now belongs, in some way, to them, along with a monthly payment they did not sign up for. Often the same person has been named executor or successor trustee, is fielding calls from a loan servicer and from relatives, and is trying to work out whether the house can be kept at all. This page walks through what the mortgage means, who has authority to deal with it, how California property tax and federal income tax treat the house, and the choices a family has.
What Happens to a Mortgage When the Borrower Dies
The debt survives the death, and it stays tied to the house. A mortgage, or in California usually a deed of trust, is a lien: a legal claim on the property that secures the loan. Under Probate Code section 9391, the holder of a mortgage or other lien on estate property may generally enforce the lien against that property without first filing a creditor's claim in probate, if it gives up recourse against the estate's other property; the personal representative may ask the court to stop such an action. In plain terms, if payments stop, the lender can move toward foreclosure on the house.
Two things are separate here. The promissory note is the borrower's personal promise to repay. An heir who never signed it is not made personally liable on it simply by inheriting, unless the heir later assumes the loan. The lien, by contrast, stays with the property.
The Garn-St. Germain Act protects the heir's ability to keep the loan. For a loan on residential property with fewer than five dwelling units, 12 U.S.C. § 1701j-3(d) bars a lender from enforcing a due-on-sale clause (a term letting the lender demand full payment when the property changes hands) on transfers including:
- a transfer on the death of a joint tenant
- a transfer to a relative resulting from the borrower's death
- a transfer where the borrower's spouse or children become an owner
This is the reason an heir generally does not have to refinance to keep the existing loan terms. Federal mortgage-servicing rules also give a person who inherits a mortgaged home a way to be recognized by the servicer as a "successor in interest"; the Consumer Financial Protection Bureau publishes what that recognition includes. Keeping, refinancing, selling or letting the house go are each explained below.
How Title Transfer Works in California — Probate, Trust, and Joint Tenancy
How the deed was held decides who may speak for the house, and when. The California Courts self-help guide on inventory and estimating property value notes that deeds are public records at the County Recorder's Office in the county where the property sits, and lists the ways a deed may read, including joint tenancy, community property, sole and separate property, or title in a trust's name.
Joint tenancy. The guide explains that when one joint tenant dies, the property passes to the other. The surviving joint tenant generally records proof of the death with the County Recorder, and no probate is needed for that house.
A living trust. When the house is titled in a trust, the successor trustee, the person the trust names to take over managing it, holds the authority. Under Probate Code section 16061.7, when a revocable trust becomes irrevocable because of a settlor's death, the trustee must serve a notification on each beneficiary and each heir of the deceased settlor within 60 days of the death, or within 60 days of learning of a person entitled to it; if the trustee's office was vacant, the period starts when the new trustee begins serving.
Probate. If the house was in the decedent's name alone, it usually goes through the Superior Court. An executor is the person a will names to carry out its terms. An administrator is generally the person the court appoints when there is no will or no executor able to serve. Both act as the personal representative. Under Probate Code section 8461, and subject to the other provisions of the same article, the order of priority for appointment as administrator begins with the surviving spouse or domestic partner, then children, then grandchildren, then other issue, and continues through further categories, including parents, brothers and sisters, more distant relatives, the public administrator, creditors, and any other person. The heir generally receives title when the court orders distribution.
Until then, a servicer usually asks for proof of authority: letters from the probate court, a trust certification, or the recorded joint-tenancy paperwork. The steps of a full estate are set out in the California estate settlement guide.
Keeping the House: Continuing Payments and Communicating With the Servicer
Keeping the house begins with one phone call to the right company. The servicer is the company that collects payments, and its name is on the monthly statement; it may not be the lender that made the loan. The personal representative, successor trustee or surviving joint tenant usually makes that contact.
Servicers commonly ask for:
- a certified copy of the death certificate
- proof of the caller's authority or relationship to the borrower
- the loan number from a recent statement
Once the servicer confirms the heir as a successor in interest, the heir can receive account information, keep paying under the existing terms, and ask about options for catching up on missed payments. Any refinance is a separate, later decision rather than a condition of keeping the loan.
If payments fell behind while the estate was being sorted out, the servicer is the place to ask about forbearance or a repayment plan. Where several heirs inherit together, all of them need to agree on the house; a disagreement among them is a contested matter handled by an attorney, discussed in the last section.
Reverse Mortgages: A Different Set of Rules
A reverse mortgage changes the picture. Under this type of loan, often a federally insured Home Equity Conversion Mortgage (HECM), the borrower makes no monthly principal-and-interest payments. The balance grows instead, and the loan generally becomes due when the last borrower dies, sells or permanently leaves the home.
Heirs of a reverse-mortgage borrower usually choose among paying off the balance and keeping the home, selling and using the proceeds to repay the loan, or giving the home to the lender. Whether the heirs can be asked to cover a shortfall depends on the loan's terms, and many federally insured loans limit repayment to the home's value. The time allowed to act is set by the loan documents and federal program rules, which the servicer can explain.
A spouse who lived in the home but was not a borrower may have different rights. The reverse-mortgage servicer and a HUD-approved housing counselor are the people who explain those rules and the heirs' options for a particular loan.
Property Taxes After Inheritance — California's Reassessment Rules
California generally reassesses property to current market value when ownership changes, and the State Board of Equalization's Change in Ownership FAQ confirms that an inheritance can be a change in ownership unless an exclusion applies. For a family keeping a mortgaged house, a higher tax bill can matter as much as the loan payment.
For transfers on or after February 16, 2021, Rev. & Tax. Code section 63.2 excludes a parent-to-child transfer, or a grandparent-to-grandchild transfer where the grandchild's parents who are the grandparents' children have died, of the transferor's principal residence, if a claim is filed. The home must become the heir's principal residence within one year of the transfer, and the heir must file for the homeowners' or disabled veterans' exemption within a year. If the home's market value exceeds the parent's taxable value plus a set amount, the difference is added to the taxable value; the county assessor's office publishes the current figure and the claim form. A home that no heir moves into is generally reassessed.
The claim is due within three years of the transfer, or before the property is transferred to a third party, or before the heir stops living there, whichever comes first; a claim is also timely if filed within six months after the mailing of a supplemental or escape assessment notice. A later claim may still be considered going forward if the property has not gone to a third party.
The BOE page also says a change in ownership statement is due within 150 days of the death if there is no probate, or with the inventory and appraisal if the estate is probated. It lists transfers between spouses as automatically excluded. Earlier transfers fell under older rules. The county assessor's office reviews a reassessment or exclusion claim.
Income Tax and the Stepped-Up Basis
A different tax question arises if the house is ever sold. "Basis" is the starting figure used to measure taxable gain. Under 26 U.S.C. § 1014(a), the basis of property acquired from a decedent is generally its fair market value on the date of death, which people call a stepped-up basis.
In plain terms, if a parent bought the house decades ago and it was worth far more at death, the heir's gain on a later sale is generally measured from the date-of-death value rather than the old purchase price. A sale soon after the death may therefore show little gain. The statute has exceptions, and 26 U.S.C. § 1014(b) also treats a surviving spouse's half of community property as acquired from the decedent in certain cases. Where an heir already owned part of the house, as a joint tenant for example, how much receives a new basis depends on how title was held.
A date-of-death value is often documented during administration. The California Courts guide notes that an early estimate is enough at first, and a formal appraisal may be needed if the estate goes to court. A CPA, an enrolled agent or a tax attorney reviews the basis and income tax question for a particular estate and sale.
What Heirs Can Do With the House — Four Paths
Each path carries real tradeoffs, and none fits every family. The keep, rent or sell comparison goes further into how they compare.
Keep and pay. The heir takes over payments as successor in interest and may refinance later. Property tax depends on whether the exclusion above is claimed and the heir moves in.
Sell. The sale pays off the mortgage, and any remaining equity goes to the estate or heirs under the will, the trust or intestate succession (the rules for an estate without a will). Selling through an agent, at auction or for cash are all possible; a cash sale can reduce repairs, showings, financing uncertainty and time, though how it compares with other routes varies from family to family. Who may sign depends on whether a personal representative, a trustee or the heirs hold authority.
Rent. The heir keeps the house, collects rent and keeps paying the loan. A child who rents the home out instead of living in it generally does not meet the principal-residence condition of Rev. & Tax. Code section 63.2, so reassessment is likely.
Let it go. When the balance exceeds the value and no one wants the house, the family may stop paying, offer a deed in lieu of foreclosure, or allow foreclosure. An heir who did not sign or assume the note is generally not personally liable, but the house is lost. A real estate attorney or a HUD-approved housing counselor can explain the process.
When Multiple Heirs Inherit the Same House
Siblings who inherit together usually become co-owners, often as tenants in common unless the will, trust or deed says otherwise. Co-owners generally all need to agree before selling, refinancing or making other major decisions.
Before distribution, individual heirs do not hold that authority. In probate, the personal representative manages the house and deals with the servicer for the estate; in trust administration, the successor trustee does. The servicer will typically ask for documents showing who holds authority before discussing the account with any single heir. The estate settlement checklist lays out these steps in order.
Disagreement does not pause the loan. A missed payment puts the whole house at risk, not just one sibling's share. If co-owners cannot agree after the house has been distributed to them, a partition action in Superior Court is the legal route for ending co-ownership; that is a contested matter handled by an attorney who litigates real property or probate cases.
