What is a date of death appraisal?
When someone dies owning real estate, the estate needs to know what that property was worth on one very specific day: the day they died. Not what it’s worth now, not what it sold for years ago — its fair market value as of the date of death. A date of death appraisal is exactly that: a retrospective valuation by a licensed appraiser, with the effective date set to the day the owner passed.
That one number ends up doing a surprising amount of work. It anchors the estate’s tax filings, the probate inventory, and — through the step-up in basis — the capital gains bill every heir will eventually face when they sell. A defensible number protects everyone downstream; a guess creates problems that surface years later, usually at the worst possible time.
A retrospective valuation, not a current one
A standard appraisal answers the question "what is this home worth today?" A date of death appraisal answers a different one: "what was this home worth on the day the owner died?" The report is written now, but its effective date — the date the opinion of value applies to — is set in the past. Appraisers call this a retrospective appraisal, and it’s a routine, USPAP-recognized assignment, not an exotic workaround.
The distinction matters because markets move. If the owner died eighteen months ago and prices have climbed since, today’s value overstates what the estate actually received. If the market has cooled, today’s value understates it. The IRS and the courts care about value at the moment ownership legally transferred — the date of death — and only a valuation pinned to that date answers the question they’re asking.
Why the IRS and probate courts want this number
If the estate is large enough to file a federal estate tax return (Form 706), the return must report the fair market value of every asset as of the date of death — and for real estate, the IRS expects that value to be supported by a qualified appraisal, not a website estimate. Some states impose their own estate or inheritance taxes with lower thresholds, so estates that owe nothing federally can still need documented values. Whether your estate crosses any of those lines is a question for the estate’s attorney or CPA.
Probate has its own demands. Executors typically file an inventory of estate assets with the court, and the house is usually the biggest line on it. That inventory drives how the estate is divided among heirs, whether debts can be covered, and whether a sale is necessary — and if any beneficiary later questions the numbers, a signed appraisal from a licensed professional is what holds the inventory together.
Step-up in basis: why heirs should care about this number
Here’s the part that affects heirs directly. When property passes at death, the heirs’ cost basis generally "steps up" to its fair market value on the date of death. If a parent bought a house for $80,000 decades ago and it was worth $450,000 when they died, the heirs’ basis is $450,000 — the decades of appreciation before death simply fall out of the capital gains calculation.
That stepped-up basis is only as good as the documentation behind it. When heirs sell the property — next year or in twenty — their taxable gain is measured from that date-of-death value. A defensible appraisal, done close to the date and kept in the file, is what lets them claim the full step-up without a fight. Without one, they’re left reconstructing a years-old value under audit pressure, which is a far worse position to argue from.
One wrinkle worth knowing exists: the estate can sometimes elect an alternate valuation date six months after death, valuing everything as of that later date instead. It’s an election made for the estate as a whole, it only makes sense in specific circumstances, and it’s squarely a decision for the estate’s CPA or attorney — but if the market moved sharply after the death, ask them about it.
How an appraiser values a home as of a past date
The mechanics are the same as any credible appraisal — comparable sales, adjustments, documented reasoning — with the data window shifted to surround the effective date. The appraiser researches sales that closed around the date of death, reads the market conditions of that period rather than today’s, and builds the opinion from what the market was actually doing then. Sales that happened well after the date can’t be used to reverse-engineer a convenient answer; hindsight is exactly what a retrospective appraisal is built to exclude.
Property condition is handled the same way: the question is what condition the home was in on the date of death. Photos, inspection reports, family knowledge, and the current state of the home all feed into that picture, and any assumptions the appraiser makes are disclosed in the report. None of this requires the appraiser to have seen the home while the owner was alive — retrospective assignments are done every day without that.
Who orders it, and when
The executor or trustee typically orders the appraisal, very often at the direction of the estate’s attorney — it’s one of the standard early tasks of settling an estate, alongside gathering accounts and notifying institutions. If you’re the executor and no one has raised it yet, raise it yourself; the attorney will almost certainly want it.
Sooner is genuinely better. The comparable sales that make the valuation easy are freshest in the months around the death, records are easier to pull, and the home’s condition hasn’t changed. A retrospective appraisal can absolutely be done years later — estates that were settled informally often discover they need one when an heir goes to sell — but the research gets heavier and the assumptions get thicker the longer you wait.
- Order early: comps around the date of death are easiest to work with now
- Keep the report with the estate records — heirs will need it at sale
- Ask the attorney or CPA about the alternate valuation date if the market moved
- One appraisal serves the 706, the probate inventory, and the basis file
Questions people ask
Not if the number needs to hold up. Assessments are mass-appraisal tax figures, often lagging and ratio-adjusted, and online estimates are algorithms with no signature behind them. The IRS and probate courts expect fair market value supported by a licensed appraiser’s opinion — that’s the standard a date of death appraisal exists to meet.
Years, if necessary — the effective date is set to the date of death regardless of when the report is written, and appraisers routinely handle look-backs. That said, the work is easier and the result cleaner when the comparable sales are recent, so order it as early in the estate process as you can.
Usually yes, for two reasons: the probate inventory still needs a credible value, and the heirs’ stepped-up basis still needs documentation for the day they sell. Whether your specific estate can skip it is a call for the estate’s attorney or CPA, but skipping it to save a few hundred dollars often costs heirs far more later.
