Records and valuation questions to resolve before inherited real estate is sold or converted to rental use.
Reviewed by Jeff Huang, CPA, MBA · Last reviewed October 9, 2026 · Sources checked October 10, 2026The tax basis of inherited real estate commonly depends on the property’s fair market value at the relevant date and the estate facts. Before a sale or rental conversion, confirm ownership, valuation support, estate documents, improvements, selling expenses, depreciation, and any state-specific issues.

- Date-of-death and estate documents
- Appraisal or other valuation evidence
- Ownership and beneficiary records

- Rental conversion and depreciation records
- Proposed sale terms and timing

A beneficiary inherits a rental interest and plans to sell it. The old purchase price alone is not enough. The CPA first checks the estate valuation, inherited ownership share, and any applicable elections, then reconciles later improvements and depreciation before modeling the sale.
