What is inherited property? Property received because somebody died, by will, by intestacy, by trust, by a recorded beneficiary deed or by survivorship. What resets at the death is the tax basis, not the mortgage.
Inherited property is real estate that changed hands because an owner died. There are five ordinary routes and they differ in how much court is involved. A will directs it and probate carries it out. Intestacy does the same job by statute when there is no will. A living trust hands it over under the trust's own terms with no court at all. A recorded transfer on death deed passes it to the named beneficiary. Survivorship, in a joint tenancy or in community property with right of survivorship, passes it to the co-owner on a death certificate. The route decides the paperwork and the timeline; it does not change what the heir owns at the end.
The tax fact that matters is the stepped-up basis. Under IRC 1014 the basis of property acquired from a decedent is its fair market value at the date of death, not what the deceased paid for it, with an alternate valuation date available in some estates. Decades of appreciation that would have been taxable gain in the owner's hands are simply not there in the heir's. Which makes a dated appraisal, prepared as of the day of death, the single most useful document in the file: it is the number every later sale is measured against. That is mechanics rather than tax advice, and the return itself is a job for a CPA.
The mortgage does not step up, or reset, or go away. The deed of trust stays recorded against the house and somebody has to keep paying it or the servicer will eventually foreclose. Federal law is on the heir's side about the due-on-sale clause: 12 U.S.C. 1701j-3(d) bars a lender enforcing one on a transfer by devise, descent or operation of law on the death of a joint tenant, on a transfer to a relative resulting from the borrower's death, or where a spouse or child becomes an owner. Separately, the consumer bureau's successor-in-interest rules require a servicer to confirm a successor and then deal with them: statements, payoff figures, and an application for loss mitigation, without their having to assume the loan first.
Two or more heirs normally take as tenants in common: undivided fractional shares in the whole property, each share sellable and mortgageable on its own, and no co-owner with a right to exclude another from any part of it. That is why a sibling living in the house without paying rent is a live dispute rather than a rule, and why a partition action, asking a court to force a sale and split the proceeds, is the exit when co-owners cannot agree on one.
A worked example
A daughter inherits her mother's house. Her mother bought it in 1994 and it is worth several times that today. Under IRC 1014 the daughter's basis is the fair market value on the date of death, so an appraisal dated to that day is the most valuable piece of paper in the file. She sells 14 months later at about 3 percent above that appraisal, and the taxable gain is measured against the appraisal rather than against 1994. The mortgage did not vanish at the death: roughly a quarter of the value was still owed, the servicer expected a payment in each of those 14 months, and the balance came off the top at closing. Had she and her brother inherited it together, each would have held an undivided half and neither could have sold the house alone.

Questions people ask
Do you have to pay off the mortgage on an inherited house?
Not immediately, but the loan stays on the house and somebody has to keep paying it. Federal law bars the lender from calling the balance due just because the property passed to a relative on the borrower's death, so the realistic choices are to keep paying, refinance into your own name, or sell and clear it at closing.
What happens if siblings inherit a house together?
They normally hold it as tenants in common, in undivided fractional shares. Each can sell or mortgage their own share and none can shut another out of the property, which is why occupancy and expenses have to be agreed rather than assumed. When they cannot agree, a partition action asks a court to order a sale and divide the proceeds.
