This is a static reference you can work down parcel by parcel. It pairs with the full due diligence guide and the max-bid calculator.
Title and liens
Confirm what you would actually be buying, and what would come with it.
- Pull the chain of title and run a lien search on the parcel. A tax deed clears most private liens, but government liens, municipal assessments, and IRS liens can survive.
- Budget for a quiet title action. A tax deed is not marketable title on its own, and clearing it takes months and money.
- Note whether the parcel is homestead. In Arizonathat changes the deed-sale opening bid, not just the owner's rights.
The parcel on the ground
Value the dirt before the auction, especially on cheap rural lots.
- Find the parcel on the county GIS and map its boundaries, size, and zoning against the listing.
- Confirm legal access. A landlocked parcel with no recorded easement is hard to use and harder to resell.
- Check flood zones and wetlands and whether the lot is buildable (perc test, utilities, setbacks).
- Look up who holds the mineral rights if that matters to your plan for the land.
The numbers
Make the math decide your bid, not the auction adrenaline.
- Price in the redemption timeline: The owner or any interested party can redeem the lien at any time until the right to redeem is foreclosed by the court. A certificate of purchase holder cannot begin a foreclosure action until three years after the sale, and the lien becomes void if no foreclosure is commenced within ten years after the month the certificate was acquired.
- If you are buying a certificate, model the return at the rate you would actually win, not the 16 percent ceiling, with the yield calculator.
- Set a defensible ceiling with the max-bid calculator, subtracting title-clearing and repair costs from resale value.
- Decide your walk-away number before the sale opens, and hold to it.
Sale-day logistics
Handle the paperwork and the money so a win does not slip away.
- Register on the county's auction platform ahead of the deadline and confirm which sale (certificate or deed) you are entering.
- Verify the exact date, time, and format on your county page. These are set county by county and can change.
If a parcel fails any item you cannot price or fix, that is your answer. See the common mistakes this checklist is built to catch.
