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.
- Read what New Hampshire says the deed conveys: No action may contest the lien's execution or the collector's deed after 10 years from the deed's recording (80:78), so a title examiner will look closely at the notice steps within that period: without the mortgagee notices of 80:65 and 80:66, no collector's deed based on the lien is valid against the mortgagee. After the tax deed the town may treat the land as its own (80:91). The statute does not prescribe what warranties, if any, the town's deed carries; read each town's terms, and order a title search and budget for a possible quiet-title action. Budget for a quiet title action if a title insurer will not accept that title.
The parcel on the ground
Value the dirt before the auction, especially on cheap rural lots.
- Find the parcel on the local 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 adrenaline of the sale.
- Know that redemption ended before this sale: 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 city or town 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 by each city or town 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.
