The City of Waco, Texas v. Harry V. Littlefield
Yes. Research the property, title, liens, and any occupants before you bid. Auction purchases are usually final and as-is, so there is no inspection contingency.
Frequently. Sales are often postponed or canceled with little notice. Always verify the date, time, and location with the official source on the day of the sale.
Most sales require a deposit at the time of sale, often by cashier's or certified check, with the balance due shortly after. Confirm the exact terms with the party conducting the sale.
In some states the previous owner can reclaim the property, or a higher bid can be entered, for a set period after the sale. Check whether a redemption or upset period applies before you commit funds.
