The House Is the Hard Part
I’m not an attorney or a CPA, and this isn’t legal or tax advice. Property law and probate rules are largely state law, and they vary a great deal. Every figure here is sourced and current as of publication. Use this to arrive at an estate attorney’s office with better questions — not to skip the visit.
The house is almost always the largest thing a family passes down, and it’s the piece people handle with the least information.
Wills get written. Beneficiary forms get filled out. Somebody names an executor. And then, separately, a well-meaning decision gets made about the house — usually around a kitchen table, usually framed as simplifying things for the kids — and it is frequently the single most expensive decision in the entire estate.
Here’s the piece of the tax code that explains why.
The rule almost nobody knows they’re relying on
When you inherit property, your cost basis for tax purposes generally resets to the property’s fair market value on the date of death. That’s the step-up in basis.
Work an example, because the abstraction hides the size of it.
You and your spouse bought the house in 1984 for $70,000. Today it’s worth $520,000.
Scenario A — your daughter inherits it when you die. Her basis steps up to $520,000. She sells it a few months later for $525,000. Her taxable gain is $5,000. The forty years of appreciation are simply never taxed.
Scenario B — you add her to the deed while you’re alive, or you deed it to her outright. Now she takes your basis. She sells for $525,000. The gain is $455,000, and she owes capital gains tax on it.
Same house. Same daughter. Same sale price. A difference that can run well into six figures, driven entirely by when the transfer happened.
Same house. Same daughter. Same sale price. A six-figure difference — driven entirely by when the transfer happened.
And here’s what makes this the cruelest version of a mistake: the parent who deeded the house early was trying to be generous. They’d heard probate was expensive. They wanted to keep things simple. Nobody at that kitchen table knew about basis, and the bill doesn’t arrive until long after the person who could explain it is gone.
This is the reason to talk to an attorney before you put a child’s name on a deed. Not after.
“But won’t there be estate tax?”
Almost certainly not, and this fear drives more bad decisions than any other.
As of 2026 the federal estate tax exemption is $15 million per person, made permanent by the 2025 tax law — $30 million for a married couple with proper planning. The overwhelming majority of American families are nowhere near that, which means the federal estate tax is not the thing to organize your house around.
Two caveats worth knowing. Some states have their own estate or inheritance taxes with far lower thresholds, so your state matters. And avoiding probate — which is a process question about time, cost, and privacy — is a separate issue from avoiding tax. People routinely conflate them and then optimize for the wrong one.
If you’re the one selling, not leaving
The other half of this: many people sell the house themselves, and there’s a large exclusion built for exactly that.
If you’ve owned the home for at least two of the last five years and lived in it as your residence for at least two of the last five years, you can exclude up to $250,000 of gain if you’re single, $500,000 if you’re married filing jointly.
Two things to flag. The ownership and use windows don’t have to be the same two years, but both must fall inside the five years before the sale. And for joint filers, either spouse can satisfy the ownership test, but both must satisfy the use test.
That exclusion is enough to cover most families entirely. It’s not enough for everyone — a couple who bought in a hot market in the 1970s can blow through $500,000 of gain without much trouble — which is where a widow or widower should be especially careful about timing, because the basis treatment on a jointly held home changes at the first death, and in community property states it changes more. This is genuinely a “get it looked at” situation rather than a rule of thumb.
The four conversations that actually prevent the mess
1. Decide whether anyone actually wants it.
Start here, because everything downstream depends on it. Families assume the house is a gift, and sometimes it’s a burden with a roof — three siblings in three states, one of whom wants to keep it, one who needs the cash, and one who won’t say. The time to find that out is while you’re alive and can hear the answer, and can change the plan in response.
If nobody wants it, saying so out loud is a kindness, not a betrayal.
2. Choose a transfer method deliberately.
The main options — a will, a revocable living trust, a transfer-on-death or beneficiary deed where the state allows it, or joint ownership — differ in cost, privacy, how long the process takes, and crucially in their tax consequences. They are not interchangeable, and the cheapest one at signing is not always the cheapest one overall. This is the hour of professional time that saves the most money of any hour you will spend.
3. Deal with what’s attached to it.
A house doesn’t pass alone. A mortgage, a home equity line, a reverse mortgage, unpaid property taxes, deferred maintenance, and the insurance policy all come along with it. A reverse mortgage in particular comes due when the last borrower dies or permanently leaves the home, and heirs typically face a tight window to repay, refinance, or sell. Families who don’t know this in advance get a hard surprise during a hard month.
4. Write down where everything is.
The deed. The title insurance policy. The mortgage information. The survey. The tax bills. The insurance. Records of major improvements — those add to basis and quietly reduce a future tax bill, and nobody can produce them after the fact from an unlabeled box in a basement.
One folder. Tell one person where it is.
The part that isn’t about money
I’d be leaving out the truth if I made this only a tax article.
The house is where the birthdays happened. There’s a doorframe with pencil marks on it. Somebody’s handwriting is on the inside of a cabinet door. That is real, it’s worth something no spreadsheet can hold, and it is exactly why these conversations get postponed for a decade.
But notice what the postponement actually does. It doesn’t protect the memories. It hands your children a legal and financial problem to solve in the worst month of their lives, while they’re also grieving you — and it hands it to them with no instructions and no chance to ask you anything.
Having the conversation now is the inheritance. The house is just the asset.
Go be bold!
This week, ask your kids one question: would any of you actually want the house? Then reply and tell me whether the answer surprised you. It surprises most people.
