Date of Death Property Appraisal: Why You Need One and How to Get It Right

If you inherit a house and eventually sell it, the IRS wants to know what it was worth on the day the owner died. That number — the date-of-death fair market value — becomes your stepped-up cost basis under IRC § 1014. Get the appraisal right, and you minimize capital gains tax on the sale. Get it wrong (or skip it), and you may overpay by thousands.

What a Date-of-Death Appraisal Is

A date-of-death appraisal is a formal written valuation of real property as of the exact date the owner died. It's prepared by a licensed residential appraiser using comparable sales, property condition, and market data — the same methodology used for mortgage lending, but backdated to a specific date rather than the current market.

The appraisal establishes two things:

1. Your cost basis for capital gains tax. When you sell the inherited property, your taxable gain is the difference between the sale price and the date-of-death value. A higher date-of-death value means a smaller taxable gain.

2. The executor's fiduciary protection. If you sell the house for a price close to the appraised value, you can demonstrate you obtained fair market value — shielding you from beneficiary claims that you undersold the property.

When to Order It

Order the appraisal as early as practical; the research timeline places it within 3–6 months after the death. The longer you wait, the harder it may be to find comparable sales and property records from that period.

If several months have passed, the appraisal is still worth getting — the appraiser will use historical sales data and make time adjustments. But fresher records may be easier to obtain.

How to Choose an Appraiser

Not every appraiser does retrospective (date-of-death) valuations. When calling appraisers, ask specifically:

• "Do you have experience with date-of-death or retrospective appraisals?"
• "Are you certified (not just licensed) in this state?" — certification is the higher credential and carries more weight if the valuation is challenged
• "Will the report comply with USPAP (Uniform Standards of Professional Appraisal Practice)?"

Get referrals from the estate attorney or CPA. Avoid appraisers recommended by real estate agents who want the listing — their incentive is a lower valuation that makes the house easier to sell.

What It Costs

A standard date-of-death appraisal costs $350–$600 for a single-family home. Complex properties (multi-unit, large acreage, unique construction) may cost $800–$1,200. The fee is an estate expense — paid from the estate account, not the executor's pocket.

The cost is almost always recovered in tax savings. Even a $10,000 difference in the appraised value translates to $1,500–$2,000 in capital gains tax at the 15% rate.

What the Appraiser Needs from You

Provide the appraiser with:

• The exact date of death
• Access to the property for a physical inspection (or photos if the property has already been substantially altered)
• The property's legal description and tax parcel number
• Any known title issues, encumbrances, or structural problems as of the date of death
• The most recent property tax assessment (the appraiser won't rely on it, but it's useful context)

The appraiser will research comparable sales that closed within 3–6 months of the date of death and adjust for differences in size, condition, location, and features. The final report typically runs 20–40 pages with photos, maps, and a detailed explanation of the methodology.

Common Mistakes

Using a Zillow or Redfin estimate instead of a formal appraisal. An automated estimate is not a substitute for a retrospective appraisal with documented methods and historical comparable sales. Use it only as a starting point, not as the sole support for the date-of-death value.

Getting a current-date appraisal instead of a retrospective one. If six months have passed and the market has moved, a current appraisal doesn't establish the date-of-death value. Make sure the appraiser knows you need a retrospective report tied to the specific date.

Cleaning up or renovating before the appraisal. The property should be valued in the condition it was in on the date of death. If you've already replaced the roof or painted the exterior, mention the before-condition to the appraiser and provide dated photos if possible.

Waiting too long and losing comparable data. MLS data and comparable sale records become harder to access after 12–18 months. The sooner you order, the cleaner the comparables.

Alternative Valuation Date

The IRS allows an alternate valuation election under IRC § 2032 on Form 706 only if it reduces both the gross estate's value and the federal estate tax due. The alternate valuation date is generally six months after death, with special rules for property disposed of during that period. For decedents who die in 2026, the basic exclusion amount is $15 million. For most families, the date-of-death value is the one that matters.

Connecting the Appraisal to Your Next Steps

The appraisal feeds directly into three decisions: how much capital gains tax you'll owe when you sell, what a sibling buyout price should be, and whether the house is worth keeping based on its current market value versus carrying costs.

The Selling or Keeping the Family Home guide includes a stepped-up basis worksheet that takes the appraisal figure and calculates your projected tax liability under different sale scenarios, plus a sibling buyout calculator that uses the same number to determine fair buyout shares.
