What is the difference between a reserve auction and an absolute auction?
In a reserve auction, the high bid is subject to the seller’s approval, which means the seller has a floor and can decline a bid that falls short of it. In an absolute auction, the property sells to the highest bidder no matter what the price is. Absolute auctions tend to draw more bidders because everyone in the room knows the house is going to sell that day.
How a reserve auction works
Before the campaign launches, the seller and the auctioneer agree on a confidential minimum. Bidders are told the sale is subject to seller confirmation, but they are not told the number.
Bidding runs the same way as any auction. If the high bid meets the reserve, the property is sold. If it does not, the seller has a choice: accept the bid anyway, decline it, or work out a deal with the high bidder afterward. Plenty of reserve auctions that fall short on sale day close on a negotiated number within a few days.
Often the reserve is met partway through the bidding. When that happens, a good auctioneer will announce that the property is now selling, because that news brings the hesitant bidders off the fence.
How an absolute auction works
There is no floor. The highest bid wins, and the seller has agreed to that in advance. Once bidding opens, the seller cannot pull the property back.
That is a real commitment, and it is also the reason absolute auctions pull a crowd. A buyer who spends time and money inspecting a house wants to know the effort can pay off. When the sale is certain, more serious bidders show up, and more serious bidders is what builds a price.
Which one fits a seller
| Reserve auction | Absolute auction | |
|---|---|---|
| Certainty of sale | Seller decides after the high bid | Sells on sale day |
| Bidder turnout | Good | Usually stronger |
| Seller protection | Confidential floor | None, by design |
| Common fit | A payoff that must be covered, heirs who want a floor | Free-and-clear property, estates that want finality, properties with broad appeal |
A reserve makes sense when there is a number you cannot go below, such as a mortgage payoff. It has a cost, though. A reserve set too high chills bidding, and a property that fails to sell on sale day has spent its best marketing.
Absolute makes sense when the property is free and clear or close to it, when it has broad appeal, or when an estate simply needs the matter settled. It is a decision to make with clear eyes before launch, not on the morning of the sale.
What bidders should know
The terms of sale state which type of auction it is. At a reserve sale, your high bid may be answered on the spot or shortly after. At an absolute sale, your high bid is the contract the moment the hammer falls.
Either way, the purchase contract has no financing contingency and no inspection contingency. You inspect during the preview period, you line up your lender before sale day, and your earnest deposit is typically non-refundable. The type of auction changes the seller’s risk, not yours.
The right format depends on the property, the debt against it, and what the seller needs from the sale. That is a conversation worth having with an auctioneer before anything is signed.

Related questions, answered straight
Do bidders know the reserve amount?
No. The reserve is confidential between the seller and the auctioneer. Bidders are told the sale is subject to seller confirmation, and nothing more. If the reserve is met during bidding, the auctioneer will usually announce that the property is now selling, which tells the room the floor is behind them.
What happens if the reserve is not met?
The seller can accept the high bid anyway, decline it, or negotiate with the high bidder and any other interested parties afterward. Many reserve auctions that fall short on sale day end in a signed contract within days. If nothing comes together, the seller can relist or try a different approach.
Which type brings a higher price?
Neither one is a promise. The market decides what a property is worth, at auction or on a listing. Absolute auctions tend to draw more bidders, and on the right property that competition can find a price a listing might not. A reserve protects the seller but can hold some bidders back.
Can a seller switch from reserve to absolute?
Before the campaign launches, yes. The format is the seller's decision, made with the auctioneer's input. Once the terms of sale are published, bidders rely on them, so changes are not something to plan on. Settle the question before the first sign goes in the yard.
