Why Do Houses Go To Auction? 10 Reasons Sellers Choose Property Auctions

why do houses go to auction

Property auctions have been around in the UK for a long time, but many people still find them confusing.

Most homes are sold by estate agents, but auctions are often used when sellers need a quick sale, or the property’s condition is more important than getting the highest price.

So, why do houses go to auction?

A public auction works differently from a traditional sale.

Each property is offered to everyone simultaneously, and once the bidding ends, the sale is legally binding.

This setup attracts sellers who want committed buyers and buyers who are ready to move fast.

This guide explains the most common reasons sellers choose auctions, the types of properties typically listed, and what both buyers and sellers should understand before entering a property auction.

From probate sales to repossessions and investment opportunities, auctions serve a clear purpose for those looking for a defined timeline and more predictable results.

Why do properties go to a property auction in the first place?

A property auction usually happens when a traditional sale is impractical, uncertain, or has fallen through.

Auctions have set timelines and follow a legally binding process, which can be appealing to auction sellers who want less risk.

At a public auction, all interested buyers can bid at the same time, so the market decides the final price. Once bidding ends and contracts are exchanged, the sale is legally binding.

This is especially appealing to sellers who have had sales fall through before.

Property auctions also attract a specific group of buyers. Instead of casual viewers, auctions bring in people who are actively looking for auction properties.

This is helpful when selling unusual or non-standard homes that may not sell easily in the regular market.

Properties typically go to auction when:

  • The house is difficult to mortgage
  • The property requires major renovation
  • There are legal or financial complications
  • The property has failed to sell previously, or is now being sold under time pressure

Since auction buyers expect these challenges, sellers are often more open about the property’s condition and legal details.

This honesty helps avoid renegotiation and leads to better results for everyone.

In the UK, property auctions are also commonly used for repossessions, investment stock, and probate sales.

Deciding if an auction is right for you depends on your goals, how quickly you need to sell or buy, and how much risk you’re comfortable with.

Auctions focus on speed and certainty, which can be helpful if a traditional sale seems too slow or unpredictable.

For sellers, auctions offer a clear timeline and a binding sale once bidding ends.

For buyers, auctions can give access to properties that are hard to find elsewhere, but there are usually tighter deadlines and less chance to negotiate.

Is it worth buying a house at auction?

Buying a house at auction can be an effective way to find investment or renovation projects.

However, buying at auction often means:

  • Limited time for due diligence.
  • Cash purchases or fast finance.
  • Accepting that properties are sold “as seen.”

While auctions can work well, they are not ideal for buyers who need flexibility or more time to complete the purchase.

Why sellers choose auctions instead of traditional selling

Selling a property through an estate agent can take months and still fall through at the last minute. Problems like surveys, mortgage issues, and buyers changing their minds are common.

Auctions lower this risk because buyers are committed as soon as bidding ends.

Many sellers choose this route when:

  • They need to sell quickly.
  • The property is non-standard or un-mortgageable.
  • The sale involves inheritance or legal deadlines.
  • They want to avoid prolonged negotiations.

For sellers, auctions offer more certainty, but you might not get the highest price. It’s an important trade-off to think about.

Top reasons why houses and properties go to auction

Here are the most common reasons why properties are sent to auction:

1. The property needs major renovation

Homes that need a lot of renovation often don’t attract buyers who need a mortgage.

Problems like structural issues, old layouts, or unfinished work can make traditional selling more difficult.

However, auctions attract buyers who expect these problems and include them in their offers.

2. The seller needs a fast sale

Speed is a big reason houses go to auction. Sellers who need money quickly, are moving, or have legal deadlines often can’t wait months for a private sale.

For context, the average time for a private treaty sale to close is around 14 to 23 weeks, versus auctions, which close within 20 days.

3. Repossessed homes

Lenders often use auctions to sell repossessed homes and recover money owed to them. Auctions help them sell quickly and cut down on costs and uncertainty.

Repossessed properties are typically marketed to buyers who are comfortable acting fast.

4. Probate and inherited properties

Many probate sales use auctions, especially when executors need to settle an estate quickly.

Inherited homes might be empty, need repairs, or have several owners, making a normal sale harder. Auctions offer a clear process and a faster sale.

5. Failed estate agent listings

If a property hasn’t sold with an estate agent, buyers may lose confidence.

Auctions have an 80% success rate, which give the property a new chance and creates urgency.

6. Unusual or non-standard properties

Properties with short leases, unusual building types, or legal issues can be hard to sell.

Auctions are often better for these homes because buyers know what they’re getting into.

7. Investment portfolio sales

Landlords and investors often sell several properties at once through auctions, which is easier than selling them one by one.

Auctions also attract buyers who are looking for investment deals.

8. Transparent pricing

At public auctions, prices are set openly as people bid against each other. This means the market decides the final price.

Sellers avoid long negotiations, and buyers can see how much interest there is.

9. Commercial or mixed-use stock

Commercial and mixed-use auction properties usually attract specialist buyers, not the general public. Auctions help sellers find these investors quickly.

10. Reduced negotiation

Traditional sales often mean long negotiations and buyers pulling out late.

At auction houses, contracts are exchanged right after bidding ends, which makes auctions less stressful for sellers who want to close quickly.

How to get involved in a property auction

If you’re considering either buying or selling your property at an auction, here’s what the process looks like.

For sellers:

  • Choose a reputable auction house.
  • Set a realistic guide price.
  • Prepare all legal documents upfront.

For buyers:

  • Review the legal pack carefully.
  • Arrange finance in advance.
  • Factor in additional costs such as fees and refurbishment.

Knowing how auctions work helps both buyers and sellers get better outcomes.

What happens if a property does not sell at auction?

Not all auction properties sell on the day. When this happens, sellers can try again at a future auction, negotiate with interested bidders afterward, or go back to selling privately.

It’s common for some properties not to sell at auction, and this doesn’t always mean there’s no demand. Often, changing the price or timing can help attract buyers next time.

Frequently Asked Questions

🏦 Do repossessed houses always go to auction?
Not always, but many repossessed houses are sold via property auctions because lenders want fast sales.
📦 If your house is sold at an auction, how long do you have to move out?
In most cases, once a house is sold at auction, contracts are exchanged immediately, and completion typically takes place within 28 days. This means sellers are usually expected to vacate the property by the agreed completion date. Timelines can vary depending on auction terms, so sellers should confirm this in advance.
⏱️ How long does an auction sale take to complete?
Most auction sales are completed within 28 days, although timelines can vary depending on the auction terms.
🏠 How to buy a house at auction with a mortgage?
Most lenders require a mortgage offer in principle before the auction, as completion deadlines are much shorter than traditional sales. Buyers should also ensure the property is mortgageable and review the legal pack carefully before bidding.
💳 How to buy a house at auction without cash?
Buyers can purchase a property at auction without cash by using alternative finance options such as bridging loans or specialist auction finance. These options often come with higher interest rates and fees and are better suited to experienced buyers who understand the risks.
🔄 What happens to properties not sold at auction?
If properties are not sold on the auction day, sellers may re-enter them into a future auction, negotiate with interested buyers afterwards, or switch back to private treaty selling. Unsold auction properties are common and do not necessarily reflect a lack of demand.

Final thoughts: Understanding property auctions

Property auctions serve a specific purpose in the UK housing market. Properties go to auction when conditions make traditional selling less suitable.

Understanding how a property auction works helps both buyers and sellers decide whether this route aligns with their priorities.

While auctions are not right for every house, they remain a practical option when you know what to expect.
