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.
- Price in the redemption timeline: Anyone with an interest in the land may redeem at any time before a foreclosure petition is filed, and a holder generally cannot petition until 12 months after the sale or taking, so the owner usually has at least a year and there is no fixed outer deadline. After a petition is filed, a party may still redeem through the Land Court by filing an answer and paying on the terms the court fixes, until a judgment forever bars redemption. The treasurer may extend the no-foreclosure period by up to 2 years when accepting a partial payment, and a town may by bylaw or ordinance offer payment agreements of up to 10 years during which it may not foreclose. Shorter routes apply where buildings on town-held land are found abandoned or the redemption amount exceeds the assessed value.
- 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: At a collector's sale, the purchaser must make an immediate deposit of whatever sum the collector considers necessary to show good faith, or the sale is void (s. 43). No statute sets a deposit for a treasurer's tax title auction or a custodian's auction; each municipality sets it in its terms of sale.
- Line up cleared funds for the balance. Not fixed by statute for a tax title auction; set by each municipality's terms. At a s. 79 sale, a buyer who does not pay the bid within ten days loses the sale and the town is deemed the purchaser (s. 80). A collector's deed must be recorded within 60 days after a collector's sale (s. 45), and an instrument of assignment within 60 days of its date (s. 52).
- 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.
