Settling an estate is a complex responsibility, especially when residential real estate is involved. One of the most common questions executors ask is: "Why can't I just use the current market value or a Zestimate to settle the estate?"

The answer lies in a specific legal requirement known as a Date of Death Appraisal (or Retrospective Valuation). If you are handling probate or filing an estate tax return, understanding this process is essential to protecting the heirs and staying compliant with the IRS.

"Without a certified appraisal report to prove Fair Market Value on the date of death, you risk a massive tax bill — or an IRS audit."

What is a Retrospective "Date of Death" Appraisal?

Most appraisals look at what a house is worth today. However, for estate purposes, the IRS and probate courts require the Fair Market Value as of the specific date the owner passed away.

Because the appraisal is performed after the fact — sometimes months or even years later — it is called a Retrospective Valuation. The appraiser must "go back in time" to analyze market conditions, comparable sales, and the property's condition as it existed on that exact date.

The Power of the "Step-Up in Basis"

The biggest financial advantage of a Date of Death appraisal is the Step-up in Basis. When a property is inherited, its cost basis for tax purposes is adjusted from the original purchase price to the value on the date of the owner's death.

Real-World Example
Parents' original purchase price (1980) $50,000
Fair Market Value at date of death $500,000
Your new step-up tax basis $500,000
Sale price $510,000
Capital gains tax owed On $10,000 — not $460,000

Without a certified appraisal report to prove that $500,000 value, the IRS may not recognize your step-up in basis — potentially exposing heirs to capital gains tax on the full $460,000 appreciation.

Why a REALTOR'S® CMA is Not Enough

While real estate agents are experts at listing homes, a Comparative Market Analysis (CMA) is not a legal document. Here is why it falls short for estate purposes:
