An heir who inherits a parent's or relative's home starts in a better tax position than most people assume. The property's basis is not what the decedent originally paid; it steps up to fair market value as of the date of death, which means decades of appreciation the decedent experienced are simply gone for income tax purposes.
What the heir does next determines what happens from there. Selling soon after inheriting, at close to the appraised value, typically produces little or no taxable gain. Moving in and living there resets the Section 121 clock as a new personal residence. Renting it out starts a new basis for depreciation and, after enough time, can open the door to a 1031 exchange on that property as investment real estate.
Each path has its own recordkeeping and timing requirements, and an heir who is undecided has more flexibility than they might expect, provided the initial appraisal is done properly and decisions are not rushed before the tax consequences of each option are understood.
The heir's basis is generally the property's fair market value on the date of death, supported by a qualified appraisal or, in some cases, comparable sales data compiled around that date. If the decedent bought the home decades ago for a fraction of its current value, that original cost is irrelevant to the heir's tax position going forward.
Getting a formal appraisal close to the date of death, even if the estate does not otherwise require one, gives the heir documentation that holds up if a later sale is examined. Waiting years and reconstructing value after the fact is a weaker position and can understate the stepped-up basis if the market has since moved.
If the heir sells within a relatively short period after inheriting, the sale price is often close to the appraised date-of-death value, which means the taxable gain is small or nonexistent. This is the simplest path for an heir who has no interest in owning real estate and wants to convert an inherited house into cash without managing it first.
Selling costs still reduce the amount realized the same way they would for any seller, and any gain that does exist beyond the stepped-up basis is taxed at capital gains rates. There is no requirement to hold an inherited property for any minimum period before selling; the stepped-up basis applies immediately upon inheritance.
An heir who moves into the inherited home starts a new clock for the Section 121 exclusion, which requires two years of ownership and use as a primary residence before that exclusion becomes available on a future sale. Because the basis is already stepped up, any gain the heir would need to shelter is only the appreciation that occurs after inheriting, not the decades of appreciation the property built up under the prior owner.
This path works best for an heir who genuinely intends to live in the property, not as a formality before a quick resale, since occupying briefly and selling before meeting the two-year use test provides no exclusion benefit beyond what the stepped-up basis already delivers.
An heir who is not ready to sell and does not want to live in the property can convert it to a rental, establishing a lease, collecting market rent, and depreciating the stepped-up basis over 27.5 years going forward. This creates a fresh depreciation schedule based on the higher inherited value rather than whatever the decedent's remaining depreciable basis was.
Once the property has been held as a genuine rental for long enough to establish investment intent, generally interpreted as at least a year or more of documented rental activity, it becomes eligible for 1031 exchange treatment like any other investment property, allowing the heir to trade into a different property without recognizing gain on the appreciation that has occurred since inheriting.
Siblings who inherit a home together each hold an undivided interest with their own share of the stepped-up basis, and disagreements about whether to sell, rent, or keep the property are common. Each heir's share can generally be treated separately for tax purposes if the ownership is properly structured, meaning one sibling could rent their share while another sells, though the mechanics of splitting a single property this way require legal structuring before any transaction, not after.
A tenancy-in-common arrangement, properly documented before any exchange or sale, is the usual vehicle for letting co-heirs pursue different tax paths with the same inherited property rather than being forced into a single joint decision.
