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.
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.
- Know when the owner’s redemption right ended: Redemption is open until the collector's deed is given, which cannot happen before two years from the lien's execution and requires 30 days' prior notice to the owner and mortgagees. Partial payments are accepted and are refunded if the deed issues before full redemption. If the town refuses the tax deed, the right to redeem continues indefinitely with interest still running. Once the deed issues, redemption ends; the former owner keeps only the repurchase right of 80:89, which is not redemption and costs more.
- 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 ahead of the deadline, online or in person as the county requires.
- Check the deposit rule: No statewide deposit rule; the governing body sets deposit, registration and payment terms under 80:80 II. Read the town's terms of sale.
- Line up cleared funds for the balance. Not fixed by statute; set in each town's terms of sale.
- 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.
