You inherited the house. Everyone is asking about taxes. That's the wrong question.

The group text starts before the will is read. A sibling asks what the tax hit is going to be. Someone forwards an article about capital gains. Someone else knows a guy who says you have to sell within a year or you get killed on it. An uncle mentions the step-up in basis with the confidence of a man who has never once looked it up. By the end of the week there are three tabs open on estate tax thresholds and a shared spreadsheet with a column labeled “IRS??”

Nobody has been in the crawlspace.

This is the most common way an inherited house goes badly, and it does not look like a mistake while it is happening. It looks like diligence. The family is asking a real question, in good faith, with real money attached. The problem is that for almost everyone reading this, the tax question has a boring answer that takes ten minutes to confirm — and the question that will actually decide tens of thousands of dollars is one no one in the thread has asked yet.

The tax question, answered, so you can stop having it

Two facts cover the overwhelming majority of inherited homes in the United States.

The federal estate tax almost certainly does not apply to you. The One Big Beautiful Bill Act set the federal estate, gift, and generation-skipping exemption at $15 million per person — $30 million for a married couple. The IRS publishes the filing threshold by year of death, and for 2026 it lists $15,000,000. Unlike the 2017 law it replaced, the new exemption carries no sunset provision and continues to be indexed annually for inflation. The cliff that estate planners spent years warning about did not arrive. If your parent’s total estate was under $15 million, there is almost certainly no federal estate tax on it. One wrinkle to name, because it is the case where “under the threshold” is not the end of it: the IRS measures the threshold on the estate plus any large lifetime gifts your parent already reported, so an estate under $15 million can still owe, and still has to file, if there were substantial reported gifts along the way. Some states levy their own estate or inheritance tax at far lower thresholds, and that is worth one phone call to a local CPA — but it is a phone call, not a research project.

The step-up in basis is intact. This is the provision the uncle was gesturing at, and it is genuinely the most valuable thing in the tax code for an inheritor. Per IRS Publication 551, the basis of property acquired from a decedent is generally “the FMV of the property at the date of the individual’s death” — or the alternate valuation date, if the estate’s personal representative elects it. Thirty years of appreciation that a parent would have owed tax on simply does not transfer to you. Your basis resets to what the house is worth the day they died.

Put those together and the practical consequence is this: if you sell an inherited house reasonably close to the date of death, your taxable gain is usually small or zero, because the sale price and the stepped-up basis are nearly the same number. That is the whole answer. It is not a strategy, it is not something you can optimize, and it does not reward six weeks of family debate.

What it does reward is getting a defensible date-of-death valuation on paper — a real appraisal, not a Zestimate — because that number is your basis, and you will want it documented if you sell later. That is a $500 line item and a two-week lead time. Order it in week one and close the tax conversation.

Then go find out what you actually own.

The question nobody asks

Here is what the family thread never gets to: inherited houses are, as a class, older and harder-used than the houses they get compared to.

This is not a hunch, and it is not anecdote. It falls out of who owns them.

Inheritance is now a structural share of the housing market. In the twelve months ending August 2025, a record 340,000 U.S. homes transferred through inheritance — about 7% of all property transfers, the highest share ever recorded. In California, nearly 60,000 properties were inherited in 2025 — 18% of all property transfers. For the first time ever, that is more than twice the number of new homes sold in the state. You may feel like you are in an unusual situation. Statistically you are in a line.

And the people you are inheriting from stayed put longer than the generation before them. The same analysis found that of homeowners born in 1938, more than 22% had left their homes between the ages of 65 and 75 — but among those born in 1946, only 17% had. Aging in place went up. That is a good outcome for the person living there, and it is the single most important fact about the building you just received.

Because a house occupied for a long time by an owner on a fixed income accumulates a very particular kind of backlog. Not neglect — deferral. Every one of those decisions was rational at the time. The roof “has a few years.” The furnace “gets us through.” Replacing a working-but-ancient panel buys nothing you can see. When you are 79 and not selling, deferring a $14,000 roof for three more winters is arguably the correct financial call. It is simply a call whose bill comes due on a specific Tuesday, to a specific person, and that person is now you.

The national numbers describe the building you are standing in. The Harvard Joint Center for Housing Studies reports that the median age of owner-occupied homes reached 42 years in 2023, up from 37 in 2013 and 31 in 2003 — the oldest housing stock on record. Owners living in homes built before 1940 spent an average of $6,700 a year on improvements and repairs, about 50% more than owners of homes built since 2010.

And this is the figure that should reorganize your thinking:

On homes built before 1940, replacements accounted for half of all remodeling expenditures — against just 9% on homes built in 2020 or later.

Old houses do not consume money through kitchens. They consume it through roofs, panels, systems, and pipes — the things that have no showroom, generate no compliments, and cannot be postponed twice. Across all homeowners, need-to-do replacement projects like roofing, windows, and HVAC made up 49% of aggregate spending in 2023, while discretionary work like kitchen and bath remodels made up 30%.

The tax code will not move your outcome by $20,000. The roof will.

Buy the information before you take the offer

Within about two weeks of the house becoming yours, someone will make you an offer on it. It will be below market and it will be framed as a kindness — no repairs, no showings, no dealing with your siblings, cash in three weeks. In a house full of grief and logistics, that offer is extraordinarily attractive, and the reason it works is that you have no independent basis on which to evaluate it. You don’t know what the house is. The buyer, who has walked four hundred of them, does.

The entire asymmetry is informational, and it is cheap to close. Before you answer anyone — buyer, sibling, or agent — buy these four things:

A date-of-death appraisal (~$500). Sets your tax basis and gives you a defensible market number. Do this one first; it has the longest lead time.

A full inspection (~$400–700). Not the drive-by an investor offers to arrange. Your inspector, hired by you, working for you.

Age and condition on the four replacement-grade systems (~$300–1,000). Roof, HVAC, electrical panel, sewer lateral. A general inspection will flag them; for anything over fifteen years old, get the specialist number. On a house of this vintage, a sewer scope is the single highest-value $200 you will spend — root intrusion is invisible, common in pre-1970 laterals, and a five-figure surprise at closing.

Two listing opinions from agents who sell this specific neighborhood (free). Ask each for both numbers: as-is, and after the specific replacement items your inspection found. The spread between those two numbers is the actual decision.

Call it $1,200 to $2,200 and three weeks. Against a six-figure asset, that is not a cost. It is the only thing standing between you and negotiating blind.

And one thing to do before any of it, on day one. Put working carbon monoxide alarms in the house. CPSC’s placement rule is one on every level of the home and one outside each sleeping area — attics and basements excepted, unless someone sleeps there. It does not depend on what you inherited. A furnace, a water heater, or a range is the obvious source, but so is a car idling in an attached garage or a generator run in the first outage, so an all-electric house is not exempt either. If there are alarms already, press the test button and read the replace-by date printed on the unit: replace it if that date has passed, if there is no date to read, or if the alarm is more than five years old, which is CPSC’s replacement interval for CO alarms — half the ten years people remember for smoke alarms. CPSC’s fact sheet puts it this way: “Alarms have a recommended replacement age, which can be obtained from the product literature or from the manufacturer. Newer alarms have an end-of-life signal that will indicate when the alarm needs to be replaced.” On an older alarm with no end-of-life signal, an expired sensor fails silently. A chirping alarm is a different message and it has more than one cause — a low battery is the common one, end of life is another, and the interval between chirps is what tells them apart, so check the unit’s manual before you conclude it is finished. Do the two maintenance steps CPSC asks for while you are there: it “recommends consumers replace the batteries in their smoke and CO alarms annually” and “test the alarms monthly”. Batteries are a few dollars; a replacement alarm is about $25. This is not a line item on the decision above; it is the condition that makes the decision safe to take slowly. Everything on this page assumes you have months to assess an old house’s systems on paper instead of meeting them in an emergency, and the equipment most likely to be sitting at the end of its deferred life here is the equipment that burns fuel.

What this looks like with real numbers

A 1958 ranch, inherited by two siblings. Date-of-death appraisal comes in at $340,000 — that is the stepped-up basis.

The day-twenty path. An investor offers $285,000, as-is, close in three weeks. There is no agent on this path, so the deductions are title, escrow, and transfer costs — call it 2%, about $5,700 — plus three weeks of carrying costs at roughly $900. Net, about $278,400. The siblings are relieved. It is over.

The report-first path. About $2,150 buys the appraisal, a full inspection, a roof assessment, and a sewer scope. The report comes back with four things: the roof is 24 years old and done ($14,000), the panel is a 100-amp fuse box that will fail any buyer’s financing ($3,200), the sewer lateral has root intrusion ($5,500), and the kitchen is dated but entirely functional.

They do the first three — $22,700 — and deliberately do not touch the kitchen. Four months of carrying costs (insurance, taxes, utilities) run about $4,800. The house lists and sells at $352,000.

About $21,000 better than the as-is offer, on roughly four months and $2,150 of upfront information.

And the tax outcome, the thing the group text spent three weeks on? The stepped-up basis of $340,000 plus $22,700 in capitalizable improvements is $362,700 — above the $352,000 sale price. There is no taxable gain in either scenario.

What there is, on both paths, is a loss against basis — and the two losses are not the same size. Neither sibling moved in, which is the fact that decides it. IRS Topic 409 is blunt: “Losses from the sale of personal-use property, such as your home or car, aren’t tax deductible.” A house you inherited and never lived in is not personal-use property. IRS Publication 559 gives the test, under Sale of decedent’s residence: if “as the personal representative, you intend to realize the value of the house through sale, the residence is a capital asset held for investment and gain or loss is capital gain or loss (which may be deductible)” — and that holds “even though it was the decedent’s personal residence and even if you didn’t rent it out.” That passage is about the estate selling during administration, but the same held-for-investment question is what decides it once the house is in the siblings’ names, and the IRS gives the losing side of it too: a house kept so a beneficiary can “live in the residence rent free” is not held for investment, and if it is then sold “without first converting it to business or investment use,” then “a loss isn’t deductible.” Which side of that line your facts fall on is a question for a CPA. Same page on the holding period: gain or loss on inherited capital assets is long term “regardless of how long you held the property.” The as-is path produces about $27,000 more loss. That is worth roughly $4,000 if it offsets long-term gains at 15%, and more — $6,000 to $6,500 — if it lands against ordinary income at 22% or 24%. Absent capital gains to offset it, the write-off against ordinary income is capped at $3,000 a year per sibling, or $1,500 for a sibling married filing separately, and carries forward, so it arrives over years rather than at closing. (A sibling who moves in converts the house to personal use, and the deduction goes with it.)

All of that assumes you sell to a stranger. One buyer makes the deduction disappear: a sibling. IRS Publication 544 is flat about it — “A loss on the sale or exchange of property between related persons is not deductible” — and the IRS’s list of related persons opens with “members of a family, including siblings, half siblings, spouse, ancestors … and lineal descendants.” So in the very common ending where one of you buys the others out, the selling siblings cannot deduct the loss, and a defensible arm’s-length appraisal does not change that. The estate-level version of the same trap is in Pub 559, which cautions that “an estate and a beneficiary of that estate are generally treated as related persons for purposes of the disallowance of a loss on the sale of an asset between related persons” — so a personal representative selling the house to one of the estate’s own beneficiaries is in the same position, with one exception the same Caution names: “The disallowance doesn’t apply to a sale or exchange made to satisfy a pecuniary bequest” — a bequest for a sum of money. A buyout can still be the right answer for a family. Price it knowing the selling siblings lose the deduction. The buying sibling can only use the loss against a later gain on the house — federal tax law lets them count it against that gain when they sell — and in three common endings the suspended loss is never used: a sibling who holds the house until death resets the basis for the heirs under §1014, one who sells for no more than they paid has no gain to offset, and one who moves in can shelter up to $250,000 of eventual gain ($500,000 for a married couple filing jointly) under §121. The sellers get nothing in any case. Put this one in front of a CPA before anybody signs.

So on a sale to an outside buyer, the tax code does lean toward the fast sale — by roughly 19% to 31% of the spread, collected over years. Net of it, the report-first path is still roughly $14,500 to $17,000 ahead. If the buyer is a sibling, neither path’s loss is deductible, and the tax code does not lean either way. And the larger deduction is only worth having if you were taking the lower price anyway: you give up $21,000 of proceeds to recover $4,000 to $6,500 of tax, slowly. Taxes were not the variable here. Not because the two paths came out the same, but because the difference they make is a fraction of the difference the roof makes.

Note also what is not in that list. No kitchen. No bathroom. No paint-everything-gray refresh. Every dollar went to a replacement item a buyer’s inspector would otherwise have found and repriced. That is the discipline that makes the spread real, and it is exactly the discipline that collapses when a family decides to “just fix it up before we list.”

When the house is not the one you sell

Everything above assumes selling, because most inherited houses are sold. If you are keeping it, or renting it, the sequence does not change — only what you do with the answer.

Keeping it. The replacement-grade backlog is still there; you have simply chosen to absorb it on your own schedule instead of pricing it into a sale. Get the same report, then sequence it over three to five years with the safety and water-intrusion items first — and a combustion-safety check on the furnace and water heater belongs in year one, not year four, because a deferral schedule is only sane on equipment somebody has actually looked at. The mistake here is the opposite of the sale mistake: people who keep an inherited house tend to start with the kitchen, because that is the part that feels like theirs, and then meet the roof involuntarily two winters later.

Renting it. The four systems become a habitability and liability question rather than a resale question, which raises the urgency on the panel and the sewer specifically. A house that was fine for one careful elderly owner is not automatically fine for a tenant and a landlord’s duty of care.

In all three cases, the order is the same: find out what it is, then decide what to do with it. The July piece on the ninety days after the call walks the protect-the-asset steps — vacancy coverage, utilities, keys — that run in parallel with this.

Why this fits the framework

Almwell exists on a single premise: what to do about your house is a decision-support problem, not a maintenance problem. Nobody actually lacks a to-do list. What people lack is a defensible way to choose what goes on it, and in what order, with real numbers attached.

Inheritance is that problem at maximum difficulty. You are asked to make the largest property decision of your life, about a building you have not lived in for decades, on a compressed timeline, while grieving, with siblings who each have a different read and none of whom have the report. Into that vacuum rushes the one question with a clean, Google-able shape — what about the taxes? — and it absorbs all the available attention precisely because it feels answerable.

So answer it in week one, in ten minutes, and be done: the exemption is $15 million, the step-up is intact, your basis is the date-of-death value, and a below-basis sale to an outside buyer, on a house nobody moved into, is usually a deductible loss. Sell to a sibling instead and that deduction is not available — that is the one piece of this worth a CPA’s hour. Then spend your actual effort on the thing with a five-figure spread attached.

The house has already made most of its decisions. Thirty years of small, rational deferrals are sitting in it right now, and they do not care which sibling is most persuasive on the group text. Your job is not to out-argue them. It is to go find out what they were, on paper, before you sign anything.

The house will pick a project for you. Planning is how you get to choose the month.
