The choice, in one paragraph
The three most common residential auction formats are reserve, absolute, and minimum-bid. A reserve auction protects the seller from selling below a set number. An absolute auction sells to the highest bidder no matter what and typically attracts the largest buyer pool. A minimum-bid auction sits between the two, publishing a public floor. Your choice depends on urgency, marketability, and how much certainty you want on the sale.
What is a reserve?
A reserve is a confidential minimum sale price agreed between the seller and the auctioneer. If bidding meets or exceeds the reserve, the property sells. If bidding stops below the reserve, the seller is not obligated to sell (the property is often "sold subject to seller confirmation" and can be re-negotiated).
The reserve is set before marketing begins and is not disclosed to buyers. Public terms simply state the auction is "subject to a reserve."
Reserve auction format
The most common residential format. It gives the seller a downside floor while still capturing competitive upside.
- Pros: seller controls the minimum acceptable price; suitable for properties with uncertain valuation; low downside risk.
- Cons: can suppress bidding if buyers believe the reserve is unrealistic; slightly smaller buyer pool than absolute.
- Best for: unique properties, higher price points, estates with fiduciary considerations, sellers who want an insurance policy on price.
Absolute auction format
The property sells to the highest bidder, no reserve, no matter the final number. It is the strongest guarantee an auction firm can make to the buyer market.
- Pros: attracts significantly more registered bidders; produces faster, more competitive bidding; buyer confidence in a real sale drives serious pre-auction preparation.
- Cons: the seller accepts the market's number. Requires a marketing plan that reaches every plausible buyer.
- Best for: highly marketable properties, motivated sellers, court-ordered or estate liquidations, sellers who value certainty and speed over a price floor.
Minimum-bid format
A hybrid. The seller publishes a floor price. Bidding opens at or above that number and the property sells to the highest bidder above the floor.
- Pros: transparent floor gives buyers confidence they will not waste diligence money; still guarantees the seller a minimum result.
- Cons: a floor that is set too high scares buyers off; a floor that is set too low leaves upside on the table.
- Best for: properties with a clearly defensible floor price (e.g., recent appraisals, comparable sales), and sellers who want the buyer pool to know their number is real.
Earnest money and buyer's premium
Two auction-specific terms every seller should understand because they directly affect participation and net proceeds.
Earnest money deposit
Typically $5,000 to $10,000 for residential properties, due from the winning bidder within 24 to 48 hours. A higher deposit filters casual bidders and improves close-through rates. A deposit set too high suppresses registration.
Buyer's premium
A percentage (commonly 5 to 10 percent) added to the winning bid and paid by the buyer. The premium funds marketing, staffing, and transaction management. Because buyers factor it into their maximum number, the premium effectively becomes part of the price discovery. For a full walkthrough see what is a buyer's premium.
Closing timeline
Auction contracts commonly close in 30 to 45 days for cash and 40 to 60 days for financed buyers. Shorter windows favor cash bidders and can slightly narrow the buyer pool. Longer windows welcome financed buyers but delay the seller's cash proceeds. Pick the window that matches your urgency, then let the marketing plan target the right buyer segments.
Reserve vs. traditional listing
A traditional listing prices a property, waits for offers, and negotiates. An auction sets terms, times the market, and lets buyers compete on a specific day. Auction advantages typically include:
- Compressed marketing window creates urgency.
- All buyers see all bids, which drives competitive pricing.
- Non-contingent contracts eliminate re-trades after inspection.
- Known close date lets sellers plan proceeds and next steps.
- Reserve or floor protects downside; upside is uncapped.
Choosing your format
Use this simple decision framework as a starting point:
- Certainty first? Absolute auction. The property will sell on auction day.
- Downside protection first? Reserve auction. The seller can walk if the number falls short.
- Transparent floor for buyer confidence? Minimum-bid format.
- Unusual property or uncertain valuation? Reserve, with an aggressive marketing plan.
- Fiduciary or court-ordered sale? Usually absolute, to demonstrate fair market value.

Frequently asked questions
What is a reserve in a real estate auction?
A reserve is the minimum price the seller will accept. If bidding does not meet or exceed the reserve, the seller is not obligated to sell.
Is an absolute auction risky for the seller?
Only if the property has been under-marketed. Absolute auctions typically attract more bidders because the sale is guaranteed, which often produces stronger final results.
Who pays the buyer's premium?
The buyer. The buyer's premium is added to the winning bid and paid by the buyer at closing. It does not come out of the seller's net proceeds.
