Due Diligence Checklist

The research every investor should do before bidding on a tax sale.

Last updated June 2026

Title & liens

Run a title search to identify ownership, mortgages, and liens. Understand which encumbrances survive the sale in that jurisdiction.

Property & zoning

Verify zoning, land use, access, and physical condition. Review parcel maps and visit the site where possible.

Value & comparables

Estimate fair value using assessed values and recent comparable sales. Set a maximum bid and stick to it.

Environmental

For commercial or industrial parcels, consider an environmental assessment to avoid inheriting cleanup liability.
