Not every appraisal serves a probate filing. And not every appraiser understands the difference between a transaction appraisal and an estate appraisal. The gap between what a probate attorney needs in a date-of-death appraisal and what most residential appraisers produce is where estate matters get complicated, slow down, or face IRS scrutiny.
This article is written for estate attorneys who need to know exactly what to ask for and why it matters which appraiser they call.
The Core Requirement: Retrospective Methodology
A date-of-death appraisal is a retrospective appraisal. It values the property as of a specific date in the past, the date the decedent died, not as of today. This means the appraiser must research the market as it existed on that specific date: comparable sales that closed near or before the date of death, active listings that were on the market at that time, and market conditions that reflect economic conditions at that moment.
This is technically demanding work. An appraiser who simply runs a current CMA and backdates it has not produced a defensible retrospective appraisal. The IRS and the courts understand the difference. A qualified appraiser producing a date-of-death appraisal should be able to articulate their retrospective methodology clearly.
USPAP Compliance and the Qualified Appraiser Standard
For any estate tax filing where an appraisal is required, the IRS requires the appraisal to be produced by a Qualified Appraiser and to meet the Qualified Appraisal standard under Treasury Regulations. This means the appraiser must hold a current state certification or license, must not have been prohibited from practicing by any professional or regulatory body, must be competent in the type of property being appraised, and must complete the appraisal within a specific time frame relative to the filing.
Probate attorneys who are unfamiliar with these requirements sometimes accept appraisals that fail to meet the Qualified Appraisal standard, creating problems that surface months later when the IRS reviews the return.
What the Report Must Contain
A date-of-death appraisal that withstands IRS review must contain: the specific date of death as the effective date of the appraisal; a description of the property as it existed on that date; an analysis of comparable sales research conducted using data available as of the effective date; a clear statement of market value supported by that research; and the appraiser's certification, license information, and signature.
The appraisal should also document any property conditions that existed as of the date of death, deferred maintenance, damage, or issues that affect value because these affect not just the estate tax but the stepped-up basis calculation and any future capital gains analysis.
Why the Stepped-Up Basis Depends on Report Quality
The stepped-up basis for inherited property is established as of the date of death. Heirs who inherit real property get a new tax basis equal to the fair market value on that date which can dramatically reduce the capital gains tax they pay when they eventually sell.
If the date-of-death appraisal understates the value, heirs get a lower stepped-up basis and pay more in capital gains tax when the property eventually sells. If it overstates the value, the estate may overpay estate taxes. A precisely documented, professionally produced appraisal protects both interests simultaneously.
The Attorney's Role in Selecting the Right Appraiser
Probate attorneys who refer estate appraisal work to general residential appraisers without verifying their retrospective methodology experience and USPAP competency are taking a documentation risk. The appraiser may be perfectly capable of valuing a home for a purchase transaction and completely unprepared to defend a retrospective appraisal before the IRS.
The right question to ask any appraiser before engaging them for estate work: "Have you produced USPAP-compliant retrospective appraisals for IRS estate tax filings, and have any of those been reviewed or challenged?" The answer and the specificity of it, tells you what you need to know.
