A call we get more often than you would think might run like this. A daughter has just buried her mother. The house in Skokie is paid off. Her brother wants to sell, and the listing agent has already named a price. Nobody has ordered an appraisal for inherited property, and nobody thinks they need one. Then the CPA asks a simple question: what was the house worth on the day Mom died? Silence.

Why an Appraisal for Inherited Property Comes First
When you inherit real estate, the tax code does something generous. It resets your cost basis. Under the IRS rules on basis of inherited property, your starting point is the fair market value on the date the owner died. Not what they paid in 1978. Not the assessor’s number. The market value on that one day.
Say the house was worth $650,000 when your mother died. You sell it six months later for $655,000. Your taxable gain is roughly $5,000, less selling costs. Without a defensible date-of-death value, you have no clean way to prove that. And the burden of proof sits with you, not the IRS.
That is why the appraisal comes first. Before the listing agreement. Before a sibling buyout. Before the return gets filed. An appraisal for inherited property is not paperwork for its own sake. It is the document that every later decision leans on. We prepare these as part of our estate planning appraisal work across Cook County every month. The families who order early spend far less time arguing later.
What a Date-of-Death Appraisal Actually Establishes
The appraisal fixes one number: market value as of the date of death. That number does a lot of work at once.
For income tax, it becomes the basis your CPA uses when the property is eventually sold. In a rising market, the reset usually wipes out decades of appreciation. In a falling market, the basis can step down instead of up, which is worth knowing before you plan around a loss.
For estate tax, the same value goes on the return if one is required. Federal estate tax reaches only very large estates, well above what most families own. Illinois is a different story. The Illinois Attorney General’s estate tax fact sheet sets the state exclusion amount at $4,000,000. It works as a threshold rather than a credit. A North Shore home, a retirement account, and a life insurance policy can cross that line faster than people expect. If they do, Form 700 is due nine months after death, and the state wants the appraisals attached.
There is one wrinkle. Under the IRS instructions for Form 706, an executor who files that return can elect alternate valuation. That values estate property as of six months after death instead. The election has to lower both the gross estate and the tax. It also applies to everything in the estate, not just the house. If your CPA is weighing that election, the appraiser needs to know, because it changes the effective date of the whole assignment.
How a Retrospective Appraisal Works When Months Have Passed
Most families call us after the fact. The death was in March, the probate case opened in June, and the CPA asked for a value in September. That is normal, and it is exactly what a retrospective appraisal is for.
A retrospective appraisal has an effective date in the past. The appraiser inspects the property today, then values it as it stood on the date of death. Only the market evidence a buyer could have seen at that time comes into play. Sales that closed after the effective date do not drive the value opinion. Under the standards published by The Appraisal Foundation, the appraiser has to state that effective date clearly and hold the analysis to it. That discipline matters, because the appraiser already knows what the market did afterward.
Condition matters too. If the kitchen was gutted after the funeral, the appraisal has to describe the kitchen that existed on the date of death. Old photos, the listing from a prior sale, permits, and family accounts all help. The more a property has changed since the death, the more this documentation earns its keep.
In practice, a retrospective assignment costs about the same as a current one. The difference is the research. A year-old effective date in a fast-moving Chicago submarket takes real care, so ask any appraiser you interview how they handle the data cutoff.
Where the Date-of-Death Number Gets Tested
The value gets tested in three places, and each one has a different audience.
The first is the sale. When you list, the appraisal tells you whether the agent’s price is realistic and what the gain will look like at closing. A pre-listing opinion of value also gives you cover if a buyer’s lender appraises low and you need to hold your ground.
The second is the split. When one sibling keeps the house and buys out the others, the buyout price should start from an independent number. Not the assessor’s figure, and not a Zestimate. We have watched families lose a year and a relationship over a $40,000 gap that a single report would have settled. Our residential appraisal team handles these buyout assignments with both sides named as intended users.
The third is the courthouse. If the estate goes through the Probate Division of the Circuit Court of Cook County at the Daley Center, the inventory will show a value for the real estate. A USPAP-compliant report backs that figure in a way an online estimate cannot. Whether a particular estate needs probate at all is a question for the family’s attorney, not the appraiser.
For the CPA: What to Ask For Before the Return Is Filed
Accountants call us about inherited property more than any other professional group. The same problems come up every time. So here is what to specify when you or your client orders the report.
First, put the effective date in the engagement. State the date of death, or the alternate valuation date if the executor is electing it on Form 706. An appraisal dated to the inspection is the wrong answer.
Second, name the intended use. Ask for a report prepared for tax basis and estate reporting purposes. That scope tells the appraiser to document market conditions as of the effective date, describe the property’s condition at that time, and explain the data cutoff. A lending form will not do that.
Third, check consistency. If the estate files Form 706, the value reported there controls the heir’s basis. The executor may also have to issue Schedule A of Form 8971 to the beneficiaries. The IRS FAQ linked above notes that a penalty can apply when a beneficiary claims a basis above the estate tax value. One appraisal, used on both the estate return and the heir’s eventual Schedule D, avoids that mismatch.
Finally, keep the report in the permanent file. The property may not sell for a decade. When it does, the basis question comes right back, and the report is the answer. Our earlier piece on qualified appraisals for donated real estate covers the related IRS rules if the heir plans to donate the property instead.
Order the Appraisal Before the Listing Agreement or the Return
Sequence is everything here. Get the date-of-death value first. Then price the listing, negotiate the buyout, or file the return with a number behind it. Families who reverse that order end up backing into a value after the sale. That is harder to defend and more expensive to fix.
Our lane is the value and the report. How the basis is claimed, whether alternate valuation makes sense, and what the return should say are properly the CPA’s work. When both sides do their part early, the number that reaches the IRS is one that holds.

Frequently Asked Questions
Do you need an appraisal for an inherited house?
In most cases, yes. Your tax basis in inherited real estate is its fair market value on the date of death. An independent appraisal is the standard way to document that value. It also settles the number for sibling buyouts, probate inventories, and any state estate tax return.
What is a date-of-death appraisal?
It is an appraisal with an effective date equal to the day the owner died. The appraiser values the property as it stood on that date using market evidence available at the time. The inspection and report can happen months later.
How do you determine the value of an inherited property?
A licensed appraiser inspects the property and reconstructs its condition as of the date of death. Then the appraiser analyzes comparable sales that closed around that date. The report explains the data cutoff and states a market value opinion tied to that effective date.
What is a stepped-up basis?
It is the reset of an inherited asset’s cost basis to its fair market value at the date of death. If the property has appreciated, the heir’s basis steps up, which reduces the taxable gain on a later sale. If the value fell, the basis can step down instead.
Can I get an appraisal months after the death?
Yes. This is called a retrospective appraisal. The appraiser sets the effective date to the date of death. The analysis then uses only information a buyer could have known at that time. It is routine work for appraisers who handle estate assignments.
