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 South Dakotathat 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: There is no fixed redemption deadline that starts at the sale. SDCL 10-24-1 lets any person redeem at any time before a tax deed is issued. What sets the outer limit is the deed process: SDCL 10-25-1 bars the certificate holder from starting that process until three years after the certificate sale, and SDCL 10-25-8 keeps the right to redeem alive until sixty days after the affidavit of completed service of the notice of intention is filed with the treasurer. Missing that sixty-day window passes the owner's, mortgagee's and lienholder's interests to the certificate holder. After the deed is recorded, the former owner has one hundred eighty days to bring an action to recover possession or to avoid the deed, which is a limitation period rather than a further right to redeem.
- If you are buying a certificate, model the return at the rate you would actually win, not the 10 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.
- Have the deposit ready: Chapter 6-13 sets no deposit for a cash sale. A buyer taking an installment contract must deposit the cash portion with the fiscal officer as soon as the bid is accepted, and the board can still decline to approve the sale, in which case the deposit is returned. A separate rule bars a bidder from the sale entirely: under SDCL 10-25-45 a county may refuse a bid from any person who is not current on all property taxes due within that county. Payment methods and any county-set deposit are county practice rather than statute, so confirm them with the county before bidding.
- Line up cleared funds for the balance. If the full purchase price is paid in cash and the board approves the sale, the board directs delivery of a deed executed by the chair of the governing board and attested by the fiscal officer. If less than the full price is paid in cash, the buyer receives a contract for deed instead, and real property sold on an installment contract may not go for less than ninety percent of the appraised value. The board fixes the number of installments, the payment dates and the interest rate, and the buyer may prepay the balance on any interest paying date. Default on an installment, on interest or on the property taxes lets the board end the contract and keep every payment already made as liquidated damages.
- 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.
