Absolute auction
An absolute auction has no reserve price and no minimum bid. The property sells to the highest bidder, whatever that bid turns out to be.
The seller cannot withdraw#
Once bidding opens, the seller is committed.
That is the whole distinction from a reserve auction, where the seller sets a threshold and may decline anything below it.
Why a seller would agree to it#
Because it brings bidders.
Attending an auction costs money — inspection, travel, time, and often a lawyer or a title search beforehand. Bidders spend that against a chance of winning.
At a reserve auction, the chance is smaller: the seller may decline the winning bid and the bidder's costs are sunk. Experienced bidders know that and discount accordingly, or do not attend.
An absolute auction removes the risk. The property is definitely selling, so the question is only at what price — and the resulting turnout frequently produces a better outcome than a reserve auction would have.
The risk the seller accepts#
A thin day.
Weather, competing sales, a poorly marketed lot, or simply nobody turning up. The seller who committed to absolute sells at whatever the room produces.
That is why absolute auctions are usually used where the seller genuinely needs certainty of sale — estates winding up, institutions disposing of assets, liquidations — rather than where they are testing the market.
Minnesota sheriff's sales are not this#
Worth distinguishing, because the mechanics look similar.
A sheriff's sale is a statutory proceeding under Minn. Stat. ch. 580. The foreclosing lender bids its own debt, and in most sales it is the only bidder.
What is sold is a sheriff's certificate, not the property — a waiting position carrying a six-month redemption period in most cases.
So neither the "absolute" framing nor the "reserve" framing applies. The lender's credit bid functions as an effective floor without being a reserve, and the thing conveyed is not the house.
For a bidder#
Absolute auctions are where genuine bargains occur, and where genuine mistakes occur.
The property is selling. Nobody is protecting the price. And nobody is protecting the buyer either — terms are as-is, deposits are usually non-refundable, and the buyer's premium is on top of the bid.
Read the terms of sale before the day, inspect what can be inspected, and set a walk-away number before the bidding starts. Auction rooms are designed to make that number move.
