What Makes a Date-of-Death Appraisal Hold Up

When an estate needs a property value, the appraisal is rarely the thing anyone wants to think about. It is, however, frequently the thing holding up everything else: the 706 can't be filed, basis can't be established, and beneficiaries can't be paid out until a credible number exists for the real property. And not just any number. A value that gets challenged, by the IRS, by a co-beneficiary, or by opposing counsel, costs far more to defend than it would have cost to get right.

After 24 years of appraising in Arizona, here's what I look for in a date-of-death valuation that holds up.

1. A true retrospective effective date

A date-of-death appraisal is a retrospective appraisal: the opinion of value is as of the date of death, not the date the report was written. That distinction does real work. The appraiser must use sales and market conditions as they existed on the effective date, and must exclude information that did not yet exist. A report that quietly leans on sales from after the date of death, or applies today's market conditions to last year's date, is the first thing a sharp reviewer pulls apart.

The report should state both dates plainly: the effective date of value and the date of the report. If those two dates aren't clearly distinguished, that's a red flag.

2. USPAP compliance, stated and actual

The Uniform Standards of Professional Appraisal Practice is the baseline for credibility in any contested or filed context. For estate work, the practical requirements are a clear scope of work, a defined intended use and intended user, a certification signed by the appraiser, and a workfile behind the report. "USPAP-compliant" on the cover means little if the report doesn't define who it's for and what it may be used for. An appraisal prepared for "estate settlement and tax filing purposes" should say so.

3. An identified, certified, accountable appraiser

A supportable value has a name attached to it. The report should identify the appraiser, the certification number and state, and carry a signature. Automated valuation models and broker price opinions have their uses, but neither carries a certification, and when a value is questioned, "the algorithm said so" is not a position anyone wants to defend. The IRS's own guidance on estate valuations contemplates appraisals performed by qualified appraisers; a certified appraiser is the cleanest way to meet that bar.

4. Comparable sales the reader can check

The heart of the report is the comparable sales grid. Supportable comps share three traits: they sold reasonably close to the effective date (before it, not after), they're genuinely similar in location and physical characteristics, and the adjustments between them and the subject are explained rather than asserted. A reviewer should be able to pull any comp in the grid from public records and see why it was chosen. When comps are thin, as they sometimes are for unusual properties, the report should say so and explain how the appraiser bridged the gap.

5. A reconciliation that shows its reasoning

The final value opinion should not appear out of nowhere. A supportable report walks through how the comparable data was weighed and why the final number sits where it does. One paragraph of genuine reasoning is worth more than ten pages of boilerplate.

6. Independence

This one is structural. The appraiser's fee cannot be contingent on hitting a number, and the value conclusion cannot be negotiated after the fact. An independent opinion is the entire product. If a valuation provider offers to "revisit" the number when a client doesn't like it, the report is compromised for any serious use, and an experienced opposing counsel will find that thread and pull it.

A note on desktop appraisals

A common question from attorneys: does the appraiser need to walk through the property? For most estate purposes, no. A desktop appraisal, performed by a certified appraiser using MLS data, public records, and market analysis, can be fully USPAP-compliant. The standards govern the credibility of the analysis, not the means of inspection, and the report simply discloses the scope. Where a property has unusual physical issues (fire damage, major incomplete construction), a desktop may not be the right tool, and a credible provider will say so before taking the order.

The practical upshot for estate practitioners: the value that holds up is retrospective to the correct date, USPAP-compliant with a stated intended use, signed by a certified appraiser, built on checkable comps, reasoned in its reconciliation, and independent. Reports like that rarely get challenged, and when they do, they survive it.
