Quick Answer: A retrospective appraisal addresses a property's value as of a specified past date. The report may be prepared now, while the effective date of value falls earlier. For an estate assignment, the requested date may be the date of death, but the executor’s tax or legal adviser should confirm the applicable date and purpose.

Three dates to keep separate
The effective date identifies the point in time addressed by the valuation. An inspection date identifies when the property was observed. The report date identifies when the report was completed.
Those dates need not be identical. A present inspection does not, by itself, establish what the property looked like at the earlier date. Explain later renovations, repairs, damage or changes in occupancy rather than leaving the appraiser to infer the timeline.
What helps explain past condition?
Gather dated photographs, prior listings, permits, plans and improvement records that are relevant to the requested date. Identify where each document came from and what it actually shows.
Missing records should be disclosed. Do not recreate a historical condition as fact because it seems likely. The appraiser can explain what information is needed and how limitations affect the assignment.
Does this establish a tax basis?
An appraisal provides a valuation conclusion for its defined assignment. Your tax adviser determines how tax rules apply to the ownership history and transaction.
The IRS distinguishes property acquired by purchase from property acquired through gift or inheritance. Do not assume that a lifetime gift and an inheritance produce the same basis treatment, or that every estate needs the same tax filing. A property's value and its tax basis are related questions, not interchangeable labels.
Order around the intended use
Before requesting a quote, identify the address, property interest, required valuation date, intended users and purpose. Tell the appraiser whether the report concerns estate administration, a contemplated sale or another matter.
If an estate also needs a current value, ask whether a separate valuation date is appropriate. A historical conclusion should not be presented as a current listing recommendation.
Frequently Asked Questions
Can an appraisal be prepared after the date of death?
A retrospective assignment can address a past date. Ask what evidence is available and whether the appraiser can accept the specific assignment.
Is today’s condition enough?
Not necessarily. Explain changes between the effective date and inspection.
Does the appraiser decide which tax date to use?
Have the estate’s adviser identify the required date and reporting purpose before work begins.
