Inherited real property research often mixes three different questions: who owns the parcel, what it was worth at a relevant date, and which tax rule applies. A defensible file keeps those questions separate.
Source hierarchy
Start with the recorded deed and probate order for ownership context. Then collect an appraisal or other valuation evidence tied to a stated date. Finally, use IRS Publication 551 for the federal basis framework. A county assessment can be a useful lead, but it is not automatically an appraisal or a determination of basis.
What to capture
Record the parcel number, legal description, recording reference, decedent, transfer date, valuation date, and source access date. If two documents identify the property differently, preserve both identifiers and flag the reconciliation instead of silently selecting one.
Method and limitation
This workflow relies on IRS Publication 551 and recorded-property research conventions reviewed August 11, 2026. State law, estate documents, and tax advice may change the result. The article does not determine basis or ownership.

Which IRS publication helps?
Publication 551 explains basis concepts and should be read with current professional advice.
What belongs in the log?
