How to set the right reserve price for your auction property
Setting the right reserve price for auction property is one of the most important decisions you will make before your sale. Get it right and you protect your bottom line while encouraging competitive bidding. Get it wrong and you risk the property not selling at all, or leaving money on the table.
In this guide, we break down exactly what a reserve price is, how it is set, and how to approach it strategically — whether you are selling through traditional auction or the modern method.
What is a reserve price in property auctions?
The auction reserve price is the minimum amount you, as the seller, are prepared to accept for your property. It is a confidential figure — buyers cannot see it. The auctioneer is not permitted to sell the property for less than the reserve, no matter how high interest is on the day.
If bidding reaches or exceeds the reserve, the sale proceeds. If it does not, the property is not sold during the auction itself. In that case, the auctioneer will typically invite post-auction offers from interested parties at or above the reserve figure.
It is worth noting that the reserve price is different from the guide price. The guide price is a published marketing figure designed to attract attention. The reserve is the real threshold — and it is yours to set.
What is an auction reserve price?
The auction reserve price is the absolute minimum amount the seller has authorised the auctioneer to accept. It is confidential — known only to the seller and the auctioneer — and it is legally binding. The auctioneer cannot sell the property for less than the reserve, regardless of how many bids have been received or how much pressure there is to get the lot away.
The reserve is the seller’s safety net. It ensures they cannot be forced into accepting a price far below their expectations simply because the room was quiet on the day. At the same time, because the reserve must be set within the parameters defined by the guide price, buyers have a meaningful indication of where the reserve is likely to sit even though they cannot know the exact figure.
The reserve price can also be changed before the auction begins — but it must be finalised and agreed before bidding starts. Once bidding is underway, the reserve cannot be altered mid-lot. If the highest bid does not reach the reserve, the property is not sold at auction, though the seller may choose to negotiate with the highest bidder immediately afterwards.
One important nuance: some properties are offered at auction without any reserve price. These “no reserve” lots will sell to the highest bidder regardless of the final figure. Properties sold without a reserve often attract intense early bidding because buyers recognise the opportunity to purchase below any floor. These lots are less common and usually involve unusual circumstances — an estate needing quick disposal, for example, or a clearance of assets at any price.
How the auction reserve price works
The reserve is usually agreed between you and the auctioneer in the days leading up to the auction, once interest has been gauged. In most cases, industry guidelines require the reserve to sit within the guide price range, or no more than 10% above a single guide figure.
In the modern method of auction, the process works slightly differently. Buyers see a guide price and starting bid, but the reserve is still confidential. Once bidding exceeds the reserve, the property is sold. This method typically allows a longer completion window — often 56 days — which suits buyers needing to arrange mortgage finance when selling property at auction through this route.
Factors that affect where to set your reserve
There is no single formula, but several key factors should inform your decision:
- Market value: Your reserve should reflect a realistic view of what the property is worth right now, not what you hope it might achieve. Use recent comparable sales in the area as a benchmark.
- Property condition: A property that needs significant work will attract a different buyer profile — typically investors or developers — who will factor in renovation costs. Your reserve needs to account for this.
- Demand and location: High-demand areas with limited stock can support a stronger reserve price. In quieter markets, a more flexible approach tends to produce better results.
- Timing: The property market moves with the seasons. Spring and autumn typically see stronger buyer activity. If you are selling in a slower period, that should factor into your reserve strategy.
- Your financial position: If you have an outstanding mortgage or need a minimum amount to proceed with your onward plans, this sets a floor below which you cannot realistically go.
If you are approaching auction day and want to make sure your legal pack is in order before a reserve is formally agreed, speaking with a specialist auction solicitor early can help you understand the full picture — including what documentation buyers will scrutinise and how that could influence your achievable price.

Common mistakes sellers make with their reserve price
Setting it too high
This is the most common error. An unrealistic auction reserve price will simply stop the sale from completing. Worse, it can damage the property’s reputation in the market — if it is seen to have failed at auction, buyers may wonder why and offer less in subsequent negotiations.
Setting it too close to the guide price
Conversely, if the reserve is set very close to the guide price, there is little room for competitive bidding to drive the price upward. A well-judged gap between guide and reserve gives buyers a sense of opportunity, which can fuel competition.
Ignoring the legal pack
The condition and completeness of your pre-auction legal pack can directly affect what buyers are willing to pay. A pack with missing documentation or unresolved title issues will put buyers off — or result in lower bids to reflect the perceived risk. Addressing these issues before the auction protects your reserve.
Failing to revisit it before auction day
Market conditions can shift between the time you instruct the auctioneer and the day of the sale. Always review your reserve in the final few days, especially if there has been limited pre-auction interest or significant changes in local market conditions.
Reserve price vs guide price: understanding the difference
Many sellers confuse these two figures, so it is worth being clear:
- Guide price: A marketing tool. It is published publicly to attract interest and give buyers an indication of the expected selling range. It is not a promise of what the property will sell for.
- Reserve price: A contractual protection. It is the minimum the auctioneer can accept on your behalf. It is kept strictly confidential between you and the auction team.
Understanding this distinction matters when planning your strategy. Setting the guide price too high relative to the reserve can deter buyers who feel it is out of their budget. Setting it too low can invite bids you would not accept.
What happens if the reserve is not met?
If bidding does not reach the auction reserve price, the property is not sold during the auction. However, this is not necessarily the end of the road. The auctioneer will typically approach all interested bidders after the sale and invite offers at or above the reserve.
This post-auction period can still result in a successful sale, though it lacks the competitive pressure of the live bidding environment. Some sellers choose to reduce the reserve slightly at this stage to secure a buyer.
How a solicitor can help before you set your reserve
Before you agree a reserve with your auctioneer, it pays to have your auction legal pack reviewed by a solicitor. Issues flagged at this stage — such as title defects, restrictive covenants, or missing planning permissions — give you the opportunity to resolve them before they affect buyer confidence and, in turn, the price achieved.
A solicitor specialising in auction conveyancing can also help you understand the auction conveyancing timeline and deadlines that buyers will face after a successful bid. If those deadlines are tight, buyers may factor in additional risk — and bid accordingly.
For guidance on what a thorough auction legal pack should contain, the National Association of Property Buyers (NAPB) provides useful information for both buyers and sellers on auction standards and best practice.
