The call from the hospital comes on a Tuesday. By Thursday, someone in the family is standing in the kitchen of a house that no longer has an owner, wondering who pays the mortgage this month. The deed will transfer through probate eventually, but three federal systems covering taxes, insurance and mortgage servicing keep running on their own clocks, indifferent to the family’s timeline. Miss a deadline in any one of them and the home’s value can erode before an heir even has the keys.
For most American families, a primary residence is the single largest asset they will ever own. Federal Reserve Survey of Consumer Finances data consistently shows that a home accounts for the biggest share of household wealth for all but the highest-income groups. Yet most heirs have never dealt with a mortgage servicer’s loss-mitigation department or calculated a stepped-up tax basis. What follows is what federal rules actually require, where the gaps are, and what to do first.
The stepped-up basis: the biggest tax break most heirs don’t fully understand
Under 26 U.S. Code Section 1014, an heir’s cost basis in inherited property resets to fair market value on the date of death. If a parent bought a house in 1985 for $90,000 and it was worth $425,000 when they died, the heir’s basis becomes $425,000. Sell soon after at that price and the taxable capital gain is essentially zero.
That benefit fades with time. Every dollar of appreciation after the date of death is taxable when the heir eventually sells. And if the heir moves in and later converts the home to a primary residence, the capital-gains exclusion under IRS Publication 523 can shelter up to $250,000 in gains ($500,000 for married couples filing jointly), but only after the heir has owned and lived in the home for at least two of the five years before the sale.
For larger estates, there is an extra compliance layer. Executors who file a federal estate tax return must submit Form 8971 and Schedule A, reporting the property’s value to both the IRS and each beneficiary. A consistency rule under 26 CFR Section 1.1014-10 then locks the heir’s income-tax basis to whatever the executor reported. The IRS instructions for Form 8971 detail the filing mechanics and exceptions.
The estate tax threshold deserves close attention right now. For deaths in 2025, the federal exemption stood at $13.99 million per individual, reflecting the elevated level set by the 2017 Tax Cuts and Jobs Act. Key provisions of that law were scheduled to sunset after December 31, 2025, which would cut the exemption roughly in half, to approximately $7 million per person adjusted for inflation. As of spring 2026, the status of that sunset directly determines whether estates that previously owed nothing now face a filing requirement and a potential tax bill. Heirs and executors dealing with a recent or pending death should confirm the current exemption with a tax professional or check the IRS estate tax page for the latest figures.
Most estates still fall below even a reduced threshold, which means most heirs establish their basis informally, often through a date-of-death appraisal or comparable-sales analysis. That works fine until the IRS questions the number years later. Getting a professional appraisal early, even when no estate tax return is required, creates a paper trail that can prevent a costly dispute down the road.
Mortgage servicing: the protections heirs have and the friction they still face
One of the most common fears among heirs is that the lender will call the entire loan due the moment the borrower dies. Federal law largely prevents that. The Garn-St. Germain Act (12 U.S. Code Section 1701j-3) prohibits lenders from enforcing a due-on-sale clause when property transfers upon a borrower’s death to certain relatives, including a spouse or child.
The Consumer Financial Protection Bureau’s servicing-rule amendments, finalized in 2016 and effective in 2018, added another layer of protection. Under 12 CFR Section 1024.30, once a servicer confirms an heir’s status as a “successor in interest,” that heir is entitled to account statements, error-resolution procedures and access to loss-mitigation options, even without formally assuming the loan. The CFPB created these rules because heirs were routinely shut out of basic account information after a family member’s death.
Servicers are also required, under 12 CFR Section 1024.38, to maintain written policies for identifying and communicating with potential successors once they learn a borrower has died. In practice, the speed and clarity of that process varies widely. Some servicers respond within weeks; others take months, during which the heir may not know the loan balance, the escrow status or whether payments are being applied correctly.
Here is a wrinkle that trips up many heirs: being recognized as a successor in interest is not the same as assuming the loan. The heir gains access to information and loss-mitigation options, but the loan remains in the deceased borrower’s name. If the heir wants to refinance, whether to lock in a lower rate or simply to afford the payments, they will need to qualify on their own credit and income. For heirs who cannot qualify, the options narrow to selling the property, negotiating a loan modification with the servicer, or risking default.
Reverse mortgages are a particularly sharp trap. If the deceased had a Home Equity Conversion Mortgage (HECM), the loan balance typically becomes due when the last surviving borrower dies. Under HUD guidelines, heirs generally have 30 days after receiving a due-and-payable notice to state their intentions, and up to six months (with possible extensions) to pay off or sell the property. Because reverse mortgage balances grow over time, the amount owed can approach or exceed the home’s value, leaving heirs with a narrow window and limited equity to work with.
For any inherited mortgage, the practical first step is the same: contact the servicer as soon as possible with a certified copy of the death certificate and letters testamentary (or letters of administration). Ask specifically to be recognized as a successor in interest and request written confirmation. If the servicer stalls or refuses to engage, file a complaint with the CFPB. That complaint alone often accelerates the process.
Insurance: the risk that moves fastest
Of the three fronts, insurance is the one most likely to cause immediate financial damage. Homeowner’s insurance policies are written in the deceased owner’s name. After death, the insurer may cancel or decline to renew the policy, especially if the home sits vacant during probate. A coverage lapse, even a brief one, sets off a chain reaction.
Under 12 CFR Section 1024.37, a mortgage servicer can force-place hazard insurance whenever it has reason to believe coverage has lapsed. Force-placed policies protect the lender’s collateral, not the heir’s equity, and they cost dramatically more than standard coverage. CFPB enforcement actions and research have documented premiums running several multiples higher than comparable voluntary policies, with costs that can quickly add thousands of dollars to the loan balance. Those charges are tacked onto the mortgage, and the heir may not realize they are accumulating until they receive a payoff statement months later.
In flood zones, the exposure is even greater. Interagency guidance from the Federal Reserve, OCC, FDIC and NCUA requires lenders to force-place flood coverage whenever it falls below the required amount, regardless of the reason. Probate is not an exception.
The fix is straightforward but time-sensitive. Within the first week or two after a death, the executor or heir should call the existing insurer to ask whether the policy can be endorsed to the estate or retitled to the heir directly. If the insurer will not do that, or if the home will be vacant for an extended period, a vacant-property or estate-property policy from a specialty carrier can fill the gap. Waiting even 30 days can be enough for a servicer to initiate force-placement.
Where the rules go quiet
Federal rules on taxes, servicing and insurance are reasonably clear on paper. What is far less clear is how often they fail heirs in practice. No federal agency publishes data on force-placed insurance incidents tied specifically to inherited properties. The CFPB does not break out successor-in-interest complaints as a separate category in its public database. And the IRS does not track how frequently heirs face basis disputes when no estate tax return was filed. The protections exist, but no one is measuring whether they actually reach the people who need them.
State-level variation compounds the problem. Probate timelines range from a few months in states with streamlined procedures to well over a year in states with formal court supervision. During that window, servicers differ in how long they wait before initiating foreclosure when payments stop, and insurers differ in how they handle policies on properties with unsettled ownership.
Then there is the human side. When multiple heirs inherit a single property, disagreements about whether to sell, rent or keep the home can stall every decision. If one heir wants to sell and another refuses, the result can be a partition action: a court-ordered sale that often yields below-market prices and generates legal fees that eat into whatever equity remains. Co-heir disputes are one of the most common reasons inherited homes end up lost, yet they fall outside the scope of any federal protection.
Another risk that catches heirs off guard: Medicaid estate recovery. Under the Omnibus Budget Reconciliation Act of 1993, states are required to seek repayment of certain Medicaid long-term care costs from a deceased recipient’s estate. Some states have expanded their recovery programs to pursue reimbursement for a broader range of Medicaid-paid services, not just nursing-home care. In many states, the family home is the primary asset targeted. An heir who assumes the house is free and clear may discover a state lien or recovery claim that significantly reduces the home’s net value. Rules vary by state, and some states exempt the home while a surviving spouse or dependent child lives there, but the obligation does not simply disappear.
Five states (Kentucky, Maryland, Nebraska, New Jersey and Pennsylvania) also impose their own inheritance taxes, separate from the federal estate tax. Rates and exemptions vary by the heir’s relationship to the deceased. An heir focused entirely on federal rules may not realize a state tax bill is coming until it is overdue.
A 90-day framework for protecting an inherited home
Because the tax, insurance and mortgage systems do not coordinate with each other or with probate courts, heirs need to act on all three fronts early. As of May 2026, here is a reasonable sequence based on current federal rules:
Week 1 to 2: Secure the property physically. Contact the homeowner’s insurance carrier to transfer or endorse the policy to the estate or heir. If the insurer requires a retitled deed before making changes, ask about interim coverage options or seek a specialty estate-property policy. If the home is in a flood zone, verify that flood coverage is current. Notify the mortgage servicer of the death and request successor-in-interest documentation requirements. If the deceased had a reverse mortgage, contact the servicer immediately to understand the repayment timeline.
Week 3 to 4: Order a date-of-death appraisal to establish the stepped-up basis, even if the estate appears to be well below the federal estate tax threshold. Gather the loan account number, most recent mortgage statement and escrow details. Check whether the estate owes state inheritance or estate taxes, and whether any Medicaid estate recovery claims may apply. If you plan to keep the home, start exploring whether you can qualify to refinance the existing mortgage in your own name.
Month 2 to 3: Submit successor-in-interest documentation to the servicer and follow up in writing. Confirm that mortgage payments are being applied correctly and that no force-placed insurance charges have appeared on the account. If the estate will take longer to settle, discuss forbearance or loss-mitigation options with the servicer before payments fall behind.
Ongoing: Keep copies of every communication with the servicer, insurer and IRS. If co-heirs are involved, establish a written agreement on who is responsible for carrying costs during probate and how decisions about the property will be made. Consult a probate attorney or tax professional for state-specific obligations, particularly given the shifting federal estate tax exemption landscape.
Why the first 90 days set the price of keeping or losing the house
An inherited home can still be the financial cushion families hope for. But the window between a loved one’s death and the point where costs start compounding is shorter than most people expect. Insurance lapses can trigger force-placed premiums within weeks. Mortgage servicers may take months to recognize an heir’s rights. A missing appraisal can cost thousands in avoidable taxes years later. A Medicaid lien or state inheritance tax bill can surface when an heir least expects it.
None of these systems wait for grief to subside, and none of them talk to each other. The heirs who protect the value of what they have been left are almost always the ones who treated those first 90 days not as a grace period but as the deadline it actually is. The house may be a gift. Keeping it that way takes early, deliberate action on every front at once.
