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: The owner, or anyone with an interest, may pay the tax, interest and costs at any time within 18 months after the lien certificate is filed in the registry of deeds. 30 to 45 days before the foreclosure date the treasurer must notify the owner named on the lien and each record mortgage holder; anyone not given timely notice may redeem until 30 days after the notice is actually given. After foreclosure there is no right to redeem, although the municipality may choose to sell or convey the property back to the former owner, and the former owner is paid any excess when the property is sold.
- 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 statutory deposit. A broker sale follows ordinary purchase-and-sale terms the municipality negotiates; where a municipality sells by its own method after a failed listing, its legislative body's authorization and published terms set any deposit.
- Line up cleared funds for the balance. Not fixed by statute; set by the purchase agreement or the municipality's authorized sale terms.
- 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.
