Buying Property at Auction: What You Need to Know
So, you’re thinking of taking the leap and buying a property at auction — congratulations!
But before you start picturing yourself as the proud owner of a charming fixer-upper, there’s one thing you need to sort out first: getting a mortgage.
Now, while it is possible to get a mortgage on an auction property, it’s often more challenging than getting a mortgage for a traditional residential property purchase. Many auction properties need significant work before they’re fit to live in — which can make them 'unmortgageable' – i.e., doesn’t have a functioning bathroom or kitchen.
Why Auction Properties Are Different
Getting a mortgage on an auction property can feel a bit like a game of Jenga — one wrong move and the whole thing could come tumbling down. But fear not, Propp’s here to guide you through the process!
The biggest challenge? Time.
Auction purchases typically come with a 28-day completion deadline, so you’ll need to move quickly.
First Things First: The Need for Speed
This is where bridging finance comes into play.
Because of the tight timelines, many investors rely on bridging loans to complete auction purchases quickly and avoid losing their deposit.
Bridging finance has become a go-to tool for two key reasons:
Speed:
Bridging lenders are built for speed. Terms can be issued quickly, and in some cases, funds can be released in a matter of days.
We got funds into a client’s account in just two days recently which saved him from losing a £100k deposit!
Flexibility:
Most auction properties need some love — and this is where bridging really stands out.
Unlike traditional lenders, bridging providers are often comfortable funding properties in poor condition and can include refurbishment costs within the loan.
This makes bridging finance ideal for investors planning to renovate and either sell or refinance.
Understanding the Costs
Before jumping in, it’s important to understand the cost of bridging finance.
It’s not just about the bridging loan interest rate — the total cost can include:
Arrangement fees
Valuation fees
Legal costs
Different interest structures (serviced, retained, or rolled-up)
That’s why it’s important to compare bridging finance options properly, rather than focusing on the headline rate alone.
Next Up: The Deposit
When you win a property at auction, you’ll need to pay a non-refundable deposit immediately.
So make sure you’ve got that cash ready — the auctioneer won’t accept an IOU.
Speaking of money, it’s also a good idea to understand your borrowing position before the auction.
That way, you can bid confidently to secure your dream property, knowing you can pay for it if you win.
Know Your Numbers Before You Bid
Before raising your paddle, you should have a clear idea of:
Your maximum budget
The likely bridging loan rates and fees
Refurbishment costs
Expected end value
This is where Propp.io becomes your best friend. Even while you’re sat in the auction room, you can plug your numbers in and quickly compare bridging loan deals, rates and fees for your chosen property in a couple of seconds, helping you make faster, more informed decisions.
Not All Lenders Are the Same
Some lenders require full valuations or are cautious about properties needing significant work.
Bridging lenders, however, often take a more pragmatic approach — sometimes using desktop valuations to speed things up.
This flexibility is a big part of why bridging finance is so widely used for auction purchases.
Be Realistic About the Property
It’s easy to get carried away with the vision.
But lenders will want to know:
What the property is worth now
What it will be worth after works
Whether the numbers support the loan
Make sure you factor in all refurbishment costs and get a clear understanding of the property’s condition before committing.
You can see how important this is in projects like this bridging refurbishment case study, where the success of the deal depended on accurate planning and execution.
Don’t Skip the Advice
One of the most important steps is speaking to someone who understands how bridging loans actually work.
A good broker can help you:
Navigate lender criteria
Structure the deal properly
Find the most suitable option
Getting this right upfront can save you time, money, and stress later on.
Don’t worry though, Propp have you covered on this bit.
Final Thoughts
Buying at auction can be a fantastic opportunity — but it’s not without risk.
With the right planning, a clear understanding of the costs and structure of bridging finance, and a solid exit strategy, you can turn an auction purchase into a highly profitable investment.
Without that? It can quickly become an expensive mistake.
