Inheriting a home: step-up basis, the 3 paths forward, and the gotchas

Inheriting a home is a high-stakes financial decision wrapped in grief. The single biggest tax benefit (the step-up in basis) makes inherited real estate one of the most tax-efficient assets the IRS gives any heir. But you have decisions to make in a relatively tight timeframe: keep, sell, or rent — and how to handle the mortgage, the appraisal, and the other heirs.

This is a guide, not tax or legal advice. Estates touch tax law, property law, family law, and probate law all at once. For any meaningful inheritance, retain a CPA AND an estate attorney.

The step-up in basis: the biggest gift the IRS gives heirs

Under IRC §1014, when you inherit property, your cost basis “steps up” (or down) to the fair market value on the date of death of the person who left it to you. All the appreciation that built up during their lifetime is wiped out for tax purposes.

This is one of the most powerful provisions in the tax code. Don’t squander it.

Worked example

Your parent bought a home in 1985 for $80,000. They died in 2026 with the home worth $600,000.

Without step-up (e.g., if they had gifted it to you while alive): your basis would be the parent’s original $80k. If you sold for $605,000, your gain would be $525,000 — potentially $130,000+ in federal cap gains and NIIT, plus state.

With step-up (inherited at death): your basis resets to $600,000. If you sold next month for $605,000, your gain is just $5,000. Functionally zero tax.

The $520,000 of built-up gain that accumulated during your parent’s lifetime is forgiven. This is why estate planners generally advise NOT gifting appreciated real estate to heirs while alive — let them inherit it at death and capture the step-up.

Community property states get a “double” step-up

In community property states (AZ, CA, ID, LA, NV, NM, TX, WA, WI), when one spouse dies, the surviving spouse’s entire community interest in jointly-held property gets stepped up — not just the deceased spouse’s half (under IRC §1014(b)(6)).

In equitable-distribution states, only the deceased spouse’s half gets stepped up; the surviving spouse’s half retains original basis.

For long-married couples in coastal CA or TX with massive home appreciation, the double step-up is one of the largest passive tax benefits available. Hold to death; don’t sell while both alive.

Get an appraisal AT date of death

The stepped-up basis is fair market value on the date of death. You need documentation that survives an audit (or an estate tax filing requirement) years later.

What to do:

• Hire a licensed real estate appraiser (NOT just a Zestimate, NOT the assessor’s tax value). $400–$700 typically.
• Order the appraisal as “date-of-death valuation”, not current market value. The appraiser uses comps from around the death date, not today.
• For estates over the federal exemption ($15M per person starting in 2026 under the One Big Beautiful Bill Act, indexed for inflation thereafter; was $13.99M in 2025), a formal appraisal is REQUIRED for the estate tax return (Form 706).
• Save the appraisal in your permanent records. You will need it whenever you eventually sell, even if that’s 30 years from now.

If you’re reading this and a parent died years ago without a date-of-death appraisal, you can sometimes reconstruct one retrospectively from MLS data and assessor records, but it’s much weaker. Get appraisals at the time.

Alternate valuation date

The estate (not the heir individually) can elect to use the value as of 6 months after death instead of the date of death — but only if (a) it lowers both the gross estate and the estate tax, AND (b) the estate is actually subject to estate tax. For most non-taxable estates, date-of-death is the only option.

The three paths forward

Once you own the home, you have three real choices. Each has a distinct tax profile.

Path 1: Sell immediately

Easiest. Step-up basis means little to no taxable gain. Net proceeds in cash.

If the home appraises for $600k at death and you sell six weeks later for $605k, your gain is $5k minus selling costs. Likely zero or near-zero tax.

The post-death holding period for inherited property is automatically long-term regardless of how long you actually held it (IRC §1223(9)). Long-term capital gains rates apply (0%, 15%, 20%) even if you sell next week.

Surviving spouse: the 2-year §121 window

Special rule: a surviving spouse can use the $500,000 MFJ §121 exclusion (instead of the $250k single exclusion) on the sale of a former primary residence for up to 2 years after the spouse’s death, provided the couple would have qualified for the MFJ exclusion immediately before the death (IRC §121(b)(4)). Combined with the (one-half or full) step-up in basis, this is one of the most powerful tax windows in the code — if you’re the surviving spouse and might sell, do it within 24 months of death.

Path 2: Move in (convert to primary residence)

Make it your home. The mortgage interest is deductible (subject to the $750k acquisition indebtedness cap), property taxes get deducted (capped under SALT), and after two years of primary residence use, you can claim the Section 121 exclusion on a future sale — $250k single / $500k MFJ on top of the stepped-up basis.

In practice, since the step-up usually wipes out most of the latent gain anyway, layering Section 121 on top is rarely the deciding factor. But if you live there 5 years and the area appreciates further, that new gain is shielded by Section 121.

Path 3: Rent it out (convert to investment property)

Now you’re a landlord. Several things happen:

• A new depreciation schedule starts based on the stepped-up basis (the building portion — not land — over 27.5 years residential).
• Rental income reports on Schedule E with all the usual deductions (mortgage interest, taxes, insurance, repairs, depreciation).
• Future losses may be passive (subject to §469 rules) unless you qualify for the Real Estate Professional Status rules or the short-term rental exception.
• You can later 1031-exchange into other investment property. See 1031 Exchange calculator.

The depreciation deduction can be substantial. If you inherited a home worth $600k with $480k allocated to building and $120k to land, your annual depreciation is $480k / 27.5 = $17,455/yr — a paper deduction against rental income.

The mortgage on an inherited home

Most people don’t realize: the existing mortgage doesn’t just disappear when the borrower dies. It needs to be paid off, assumed, or kept current.

Garn-St. Germain protections

The Garn-St. Germain Depository Institutions Act of 1982 (12 USC §1701j-3(d)) bars a lender from triggering the due-on-sale clause for several specific transfers, including:

• A transfer to a relative resulting from the death of a borrower (no occupancy requirement)
• A transfer where the spouse or children of the borrower become an owner
• A transfer to a borrower’s spouse incident to divorce
• A transfer into an inter-vivos (revocable living) trust where the borrower remains a beneficiary

These protections apply to residential property of fewer than 5 dwelling units. This means you can usually continue paying the existing mortgage without refinancing, even if it carries a low locked-in rate from a prior era. The lender must allow you to take over payments.

You may need to formally assume the loan (be added as the borrower of record) for credit-reporting purposes. Process varies by servicer.

VA, FHA, USDA assumptions

Beyond Garn-St. Germain, VA, FHA, and USDA loans are explicitly assumable with lender approval. The heir can be added as the borrower of record.

If a parent had a 2.75% VA loan from 2021 and you inherit the house in 2026, assuming that loan instead of refinancing is potentially worth tens of thousands of dollars per year. See the VA loans complete guide and Assumable Mortgage calculator.

Conventional loans

Garn-St. Germain protects you from automatic acceleration on inheritance, but the lender may still want a formal assumption process, or in some cases require a refinance. Read the loan documents and contact the servicer.

If the heirs intend to sell within a few months, just keep the existing mortgage current with payments from the estate or heirs (will be paid off at sale).

Multiple heirs: the most common stuck point

When two or more heirs inherit jointly:

• All inherit at the same stepped-up basis (proportional to their share).
• All must agree on what to do (sell, hold, rent, partition).
• Any one heir can force a sale via partition lawsuit, where the court orders the property sold and proceeds split. Slow, expensive, family-relationship-destroying.

The two common configurations:

1. All heirs agree to sell: easy. Estate or heirs sell, proceeds split. Each heir reports their pro-rata share of any gain (usually small or zero given step-up).
2. One heir wants to keep, others want to cash out: the keeping heir buys out the others. Often financed by a new mortgage in the keeping heir’s name covering the buyout amount.

Buyout structure

Keeping heir gets a new mortgage at, say, 75% of stepped-up value, pays out the other heirs in cash for their shares. Functionally similar to the divorce buyout in divorce and your mortgage.

The buyout itself is generally NOT a taxable event for the receiving heir — they’re selling their inherited share at FMV, with basis equal to FMV (since step-up), so gain is roughly zero.

Avoiding the disaster scenario

The worst outcome: heirs disagree, nobody pays the mortgage, taxes go unpaid, the house deteriorates, and partition litigation runs for years. Resolve the path forward in the first 60 days when emotions are still raw but possible to channel.

Document everything in writing. Sibling disputes over inherited homes have ended families.

The depreciation recapture trap (if you rent then sell)

If you go Path 3 (rent it out) and then sell years later, the depreciation you took during the rental period gets recaptured at sale at up to 25% federal (IRC §1250 unrecaptured gain), plus 3.8% NIIT and state tax.

The step-up basis does not help with recapture on depreciation you took post-inheritance. It only wiped out the prior owner’s gain.

Worked example: inherited at $600k stepped-up basis. You rent for 10 years, depreciating $17,455/yr = $174,550 total. You sell for $700k.

• Gain: $700k − $600k = $100k base gain
• Plus $174,550 of depreciation that gets “added back” to gain
• Total gain: $274,550
• $174,550 taxed at up to 25% federal = up to $43,638
• $100k taxed at LTCG (15%/20%) = $15k–$20k
• Plus NIIT (3.8%) on most of it
• Plus state tax

The recapture surprise often runs $40k-80k on a property held as a rental for a decade.

The escape valve: 1031 exchange into another investment property defers all of this (see 1031 Exchange and the 1031 exchange step-by-step guide). Or hold to YOUR death and your heirs get another step-up (the basis “step-up at death” is one of the few ways to escape recapture permanently).

Estate tax (rarely an issue)

Federal estate tax exemption for 2026 is $15M per person (raised permanently by the One Big Beautiful Bill Act in July 2025, indexed for inflation thereafter; the prior TCJA sunset was averted). MFJ couples can effectively shield $30M with portability via Form 706.

For most heirs, the federal estate tax is irrelevant — the home is part of an estate well below the exemption.

State estate tax has lower thresholds in some states:

• Massachusetts and Oregon: $1M
• Washington, Vermont: $2M–$5M
• New York: ~$6.94M with a “cliff” (cross it and the entire estate gets taxed)
• Maine, Minnesota, Connecticut, DC, Hawaii, Illinois, Maryland, Rhode Island: lower thresholds, vary

Maryland and several others ALSO have inheritance tax (paid by heir, not estate — different mechanism). Check your state.

For estates that DO trigger estate tax, the home valuation drives the tax. Get the appraisal right (fight a high IRS valuation if challenged).

Probate timeline

Most homes pass through probate — the court-supervised process of validating the will and transferring assets. Typical timeline:

• Simple probate: 4–9 months
• Contested probate: 12–24 months or longer
• Independent / informal probate (allowed in many states for uncontested estates): 3–6 months

During probate:

• The estate (not heirs personally) is responsible for mortgage, taxes, insurance, utilities, basic maintenance.
• If the estate has no liquid assets, heirs may need to advance funds (reimbursable from estate proceeds).
• The home cannot be sold until the executor/personal representative has authority (granted by the probate court).
• Insurance: the deceased’s homeowner’s policy may technically lapse on death; some policies allow a 30-60 day grace period. Verify with the insurer immediately and arrange continuing coverage (often a vacant-home policy if nobody’s living there).

Avoiding probate (for next time)

Estate planning tools that avoid probate for a home:

• Revocable living trust holding title to the home (most common approach for moderate estates)
• Transfer-on-death (TOD) deed / beneficiary deed — allowed in ~30 states, lets you name a beneficiary directly on the deed
• Joint tenancy with right of survivorship (JTWROS) — passes automatically to surviving owner, but doesn’t handle the second death
• Tenancy by the entirety (married couples in some states) — similar to JTWROS

Encourage parents to set this up while alive. The cost is a few thousand dollars; the time saved at death is enormous.

Common mistakes

• Not getting a date-of-death appraisal. Reconstructing FMV years later is much weaker. Spend $500 in the first 90 days.
• Selling immediately without thinking through the alternatives. Sometimes inherited property is a wealth-building opportunity (rent it, hold, eventually 1031-exchange). The path is reversible if you hold for now.
• Forgetting that step-up applies to RENTAL properties too. A parent’s rental portfolio inherited gets stepped up — often the largest “gift” in the entire estate.
• Sibling stalemates that drag on for years while taxes, insurance, and maintenance pile up.
• Not assuming a low-rate inherited mortgage when possible. A 2.75% loan from 2021 is enormously valuable; don’t refinance it just because the lender suggests it.
• Not respecting the rental conversion tradeoff: going from a step-up’d, free-of-cap-gains primary residence to a depreciation- recapture-prone rental moves you out of one tax regime and into another. Sometimes worth it; sometimes not.
• Letting the deceased’s homeowner’s insurance lapse. An uninsured fire during probate is a catastrophe.
• Failing to record the title transfer after probate. If the home shows the dead person on the deed years later, you have a problem to solve before you can sell.
• Treating the home as separate from the rest of the estate. Tax planning should consider the whole estate, not just the house.

When to consult a professional

For any meaningful estate, you need both:

• CPA to handle the income tax filing for the year of death (Form 1040 final return), the estate’s income tax (Form 1041), and the estate tax return (Form 706) if applicable. Helps with step-up documentation and any rental conversion election.
• Estate attorney in the deceased’s state of residence to navigate probate, title transfer, multi-heir issues, and any will contests.

The few thousand in fees prevents six-figure mistakes.

Tools you’ll use

• Capital Gains — model gain/tax if you sell (usually small post-step-up)
• Assumable Mortgage — if the inherited loan is VA/FHA/USDA at a low locked-in rate
• Sell vs Rent — financial comparison if considering Path 3
• Rental Tax Shelter — depreciation math on the stepped-up basis
• 1031 Exchange — defer recapture if you eventually sell a rented inheritance
• Cost Basis Tracker — start the new basis log with the stepped-up value
