What is a Reserve Price in Property Auctions? Everything You Need To Know
A property auction does not always end with a sale.
Sometimes when bidding stops, the auctioneer does not confirm that the property is sold. When that happens, it means that the final bid has not reached the seller’s minimum acceptable amount.
This minimum amount is known as the reserve price.
You’ll learn what a reserve price in property auctions is, how it works during an auction sale, how it differs from a guide price, and what happens when bidding does not reach it.
What is a reserve price?
A reserve price is the minimum amount a seller will accept for their property at auction, which the auctioneer and seller usually agree on before auction day.
The reserve price is often confidential: buyers may see the guide price, or the advertised price used to market the property, but they do not always see the reserve price. The guide price helps attract interest and encourage bidding, while the reserve price is the minimum price needed for the sale to proceed.
If bidding reaches or exceeds the reserve price, the auction property can be sold. If not, the property may not be sold in the room.
Ultimately, the reserve price determines whether the sale can go ahead. That’s why buyers shouldn't confuse the guide price with the seller’s true minimum.
What is the point of a reserve price?
The main point of a reserve price is to protect the seller.
Without one, a property could sell for less than what the seller is willing to accept. This matters especially when bidding is slow or buyer interest is weaker than expected.
A reserve price gives the seller a level of control. It serves as a price floor, ensuring the property isn't sold for less than its worth.
How to find out the reserve price at a property auction?
Buyers will usually not know the exact reserve price before the auction starts, but there are a few ways to make an informed guess. For instance, buyers can look at:
- The guide price
- Recent local sales
- The property’s condition
- How the auctioneer describes the lot
The guide price can give a rough indication, but it is not the same as the reserve price.
If you want to bid on a property, it helps to do your homework before auction day. Research the local market, compare similar properties, and set your limit early.
What is an auction guide price?
An auction guide price is the advertised figure used to market a property before the auction.
Its job is to attract attention and encourage interest from buyers. It gives bidders a starting point, but it does not guarantee the property will sell at that level.
Now this is where beginners often get confused.
They may assume that the guide price is the amount needed to buy the property, but in reality, the property may only sell if bidding reaches the reserve price.
In a nutshell:
- The guide price gives buyers a starting point.
- The reserve price decides whether the sale can happen.
Reserve Price vs Auction Guide Price: What is the Actual Difference?

The difference between the guide price and the reserve price is simple: the guide price is public, while the reserve price is private.
The guide price appears in marketing materials and auction listings. It’s there to draw attention and encourage bidders to take part.
On the other hand, the reserve price is the seller’s minimum acceptable amount. It is usually agreed with the auctioneer in advance, and is not always shared with buyers. This means a property can attract plenty of interest at the guide price and still not sell if bidding does not reach the reserve price.
If you're a buyer, this distinction matters because it shapes your expectations. If you treat the guide price as the final target, you may underestimate what the seller is prepared to accept.
What is a reservation fee?
The reservation fee different from a reserve price.
It is a fee usually applied in online conditional auctions, and is paid by a buyer immediately after winning a conditional auction to move the transaction forward.
The reservation fee is not part of the seller’s minimum acceptable price. Instead, it is a separate payment set out in the auction terms. So while the reserve price affects whether the property sells, the reservation fee only comes into play after the winning bid.
How do reserve prices work during a property auction?
Before the auction begins, the seller and auctioneer agree on the reserve price. Once the bidding starts, the auctioneer takes bids as usual.
If the bidding reaches or exceeds the reserve price, the auctioneer can confirm the sale. However, if the bidding stops below that figure, the property may remain unsold. Even if someone made the highest offer in the room, that does not mean the sale will go ahead.
In some cases, the auctioneer may stop to speak to the seller or invite the highest bidder to negotiate after the auction ends. This is why the reserve price matters so much; it can decide the outcome of the entire bidding process.
How does a reserve price protect the seller?
A reserve price protects the seller by setting a price floor. This can be useful when:
- There are fewer bidders than expected
- Buyer demand is weaker on the day
- The property is unusual or harder to value
- The seller wants to avoid accepting too low a figure
It also gives the seller more confidence going into the auction because there’s a guarantee that the property will not be sold unless the bidding reaches an acceptable level.
Advantages and Disadvantages of Reserve Prices
| Advantages | Disadvantages |
|---|---|
| Protects the seller from accepting too low a price | Can prevent a sale if the reserve price is set too high |
| Helps set a clear minimum amount | May frustrate buyers who expect the guide price to be enough |
| Gives the seller more control over the outcome | Can reduce transparency for bidders |
| Works well when market conditions are uncertain | May lead to post-auction negotiation instead of a clean sale |
| Helps avoid underselling the property | A poorly-judged reserve price can reduce bidding momentum |
Typical Misconceptions about Reserve Prices
New property auction buyers misunderstand how reserve prices work. Some of the common misconceptions include:
The guide price and reserve price are the same. They are not; one is public and used for marketing. The other is the seller’s minimum.
The highest bid always wins. Not necessarily. If the bid stays below the reserve price, the property may not sell.
Buyers can always find out the reserve price before the auction. In most cases, they cannot.
A low guide price means a cheap property. Not necessarily. The guide price may simply be there to attract more interest.
The seller loses control of the auction when it starts. The reserve price is one of the ways the seller keeps control.
What happens after a property auction involving a reserve price?
If bidding reaches the reserve price, the auctioneer can confirm the sale. In an unconditional auction, that usually means the contract becomes binding after the hammer falls.
If bidding does not reach the reserve price, the property may remain unsold. But that does not always mean the deal is over.
In some cases, the highest bidder may be invited to negotiate after the auction. The seller may accept a lower offer, reject it, or choose to relist the property later. Buyers should stay engaged even if the property does not sell in the room because a deal may still happen once the auction ends.

A reserve price is the seller’s minimum acceptable amount, and decides whether the sale proceeds. For buyers, it explains why the highest bid does not always secure the property. For sellers, it offers protection against selling for less than they are prepared to accept.
