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 Oregonthat 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: Redemption in Oregon runs before the public ever buys. After judgment the parcels are held by the county for two years from the date of the judgment of foreclosure, unless redeemed sooner, and the former owner keeps possession during that period unless waste is committed. At least one year before the period ends the tax collector mails a notice of expiration of redemption, and 10 to 30 days before it ends the tax collector publishes a general notice. Unredeemed parcels are then deeded to the county, and all rights of redemption terminate when the deed to the county is executed. A buyer at the county's later sale therefore takes property that is no longer subject to any redemption right. ORS 275.180 separately lets the county governing body sell a parcel back to the record owner or contract purchaser of record at any time, without notice, for the taxes and interest charged when the county acquired it plus six percent a year; that is a discretionary repurchase, not a redemption right.
- 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: No statewide deposit amount. ORS 275.110 leaves the conditions and terms of sale to the county governing body's order, and the notice of sale states them. Deposits, bidder registration, and accepted forms of payment therefore vary by county; read the county's notice of sale before the auction.
- Line up cleared funds for the balance. Under ORS 275.190 the sale is to the highest and best bidder either for cash, or for at least 10 percent of the price in cash with the rest paid under a purchase agreement in equal installments over no more than 20 years at an interest rate the county sets, and the county must say in its advertisement which terms apply. A sale for cash may be structured as an earnest money deposit followed by one payment of the balance. The payment deadline is set by the county's 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.
