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 Pennsylvaniathat 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: Under the Real Estate Tax Sale Law there is no redemption of any property after the actual sale. The owner's last opportunity is to discharge the tax claim before the sale by paying the claim and interest, any other tax claim or judgment and interest, all accrued unpaid taxes, and the record costs, or a smaller amount the political subdivision agrees to accept. Payment before July 1 of the year following the notice of claim removes the property from the sale list entirely. Payment after that date but before the actual sale still stops the sale, though the parcel and the owner's name may already appear in the advertising.
- 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: The Real Estate Tax Sale Law sets no deposit and no buyer premium. What it does require is pre-registration: anyone intending to bid at an upset or judicial sale must appear and register at the bureau no less than 10 days before the sale, once per scheduled sale, and a county may charge a fee for filing the application. The application names the applicant, and every officer, member and manager if the applicant is not an individual, and carries an affidavit that the applicant owes no delinquent real estate taxes anywhere in the Commonwealth, has no municipal utility bill more than one year outstanding, is not acting for a person barred under section 601(d), and has not let an uncorrected housing code violation stand after conviction in the last three years. A false statement is prosecutable as a second degree misdemeanor. The bureau sends the list of registered bidders to every municipality in the county at least five days before the sale.
- Line up cleared funds for the balance. At an upset sale the purchaser pays the entire purchase money to the bureau on the day of the sale, no later than one hour before the close of business or at another time that day the bureau designates. Miss it and the sale is voided and the property is put up again at the same sale or at an adjournment. The act sets no payment window for a judicial sale; the bureau delivers the deed after the purchaser pays the price, and deeds for property exposed at a judicial sale may not be exchanged sooner than 20 days nor later than 45 days after the sale. Counties publish their own judicial-sale payment terms, and many require certified funds at strike-down. The deed is recorded at the purchaser's cost.
- 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.
