Date of Death Appraisals in Oregon: What Executors and Families Need to Know

When a loved one passes away, the last thing most families want to think about is property valuation. But if real estate is part of the estate, federal and state tax obligations require a precise determination of the property's fair market value as of the exact date of death.

This is called a date-of-death appraisal, and it is one of the most specialized assignments in residential real estate valuation.

Why the Date of Death Matters

The IRS uses the fair market value of assets at the date of death to establish the estate's taxable value. This figure determines whether federal estate taxes apply and, critically, sets the cost basis for the property going forward.

If the property is later sold, the difference between the sale price and the date-of-death value determines capital gains tax liability for the heirs. An inaccurate or poorly documented valuation at this stage can cost families thousands of dollars in unnecessary taxes, or trigger an audit that creates months of additional stress.

Oregon has its own estate tax with a threshold significantly lower than the federal exemption. Consult with a CPA or estate attorney for the current threshold that applies to your situation, but be aware that many Portland-area properties, even modest single-family homes, can push an estate past the taxable threshold on real estate value alone.

What Makes This Appraisal Different

A date-of-death appraisal is a retrospective valuation. The appraiser must determine what the property was worth on a specific past date, not today. This introduces additional complexity:

  • Historical comparable sales: The appraiser can only use sales data from around the date of death. If the person passed six months ago, current sales are irrelevant.
  • Property condition as of the date: The appraiser must value the property in the condition it was in when the owner passed, not its current condition.
  • Market context reconstruction: Portland's market can shift meaningfully in just a few months. The appraiser must accurately reflect conditions as they existed on the valuation date.

The Executor's Responsibility

If you are serving as executor or personal representative of an estate in Oregon, ordering a date-of-death appraisal is one of your fiduciary obligations. You are legally required to report the fair market value of estate assets to the IRS (Form 706) and to the Oregon Department of Revenue.

Using a Zillow estimate, a real estate agent's opinion, or a casual assessment is not acceptable. These are not defensible documents. If the IRS or Oregon DOR challenges the reported value, you need a certified appraisal prepared under USPAP standards.

Timing Considerations

Federal estate tax returns are due nine months after the date of death (with a possible six-month extension). Oregon follows a similar timeline. Ordering the appraisal early gives the appraiser adequate time to research historical data and prepare a thorough report.

The Alternate Valuation Date

In some cases, the executor may elect to use an alternate valuation date, exactly six months after the date of death. This option is available when the estate's total value has declined during that period. Consult with an estate attorney or CPA before making this election.

What We Need From You

To produce the most accurate date-of-death appraisal, we ask executors and families to provide the exact date of death, any photographs of the property taken around that time, documentation of the property's condition, and access to the property for a current inspection.

At Bernhardt Appraisal, we have spent over 30 years helping Portland families navigate estate transitions with professionalism and genuine care. Our reports are specifically prepared to meet IRS and Oregon DOR standards, giving executors and families the defensible documentation they need during an already challenging time.
