Can you buy a house at auction with a mortgage?

Written by: Kerry Santucci CeMAP MLIBF

The UK property auction market has transformed significantly over the past few years.

Whether you’re eyeing a Victorian terrace ripe for renovation or a commercial unit with potential, understanding your financing options makes all the difference between winning a bid and walking away empty-handed.

As a mortgage broker who’s helped countless buyers through auction purchases, I can tell you that preparation and timing matter more than anything else. The standard 28-day completion requirement means you’ll need different strategies than a typical property purchase.

Modern UK Property Auctions

Property auctions in Britain now fall into two main categories: traditional in-person events and modern online platforms.

Companies like SDL Auctions and Allsop run regular online events, while traditional auction houses still hold in-person sales.

Each has its advantages, but both share the same strict completion requirements.

When you win a bid at auction, you’ll need to pay a 10% deposit immediately.

The remaining 90% must be paid within 28 days – and yes, that deadline is absolutely firm. Missing it means losing your deposit and potentially facing legal action.

Understanding Your Finance Options

Traditional mortgages can work for auction properties, but they need careful planning.

Most high street lenders take 6-8 weeks to set up a mortgage – well beyond that 28-day deadline.

Some specialist lenders work more quickly, but they’ll want extensive information about both you and the property before making any commitments.

Getting a mortgage agreement in principle before the auction helps, but remember – it’s not a guarantee.

The property still needs to meet the lender’s criteria, which can be challenging with auction properties that often need work.

Bridging finance often proves more practical.

These short-term loans can be arranged within 7-14 days and work well for auction purchases. While the interest rates are higher than standard mortgages, they provide the speed and certainty auction buyers need.

A typical bridging loan might last 6-12 months, giving you time to either sell the property or refinance onto a standard mortgage.

Fastest Options

Bridging loans offer quick completion (7-14 days) with loans up to 75% of property value. Cash purchases provide the most straightforward approach but tie up significant capital.

Traditional Routes

Standard mortgages can work with proper planning but need careful preparation before the auction. Buy-to-let mortgages suit investment properties but also need advance arrangement.

Alternative Solutions

Mixed funding combines different sources like savings and loans. Commercial finance suits business properties, while development finance works for major renovation projects.

Family and partnerships can provide additional options through loans, guarantees, or joint ventures.

Getting Your Finances Ready

The most successful auction purchases I’ve seen involve thorough preparation.

You’ll need proof of funds for your deposit ready before bidding. This means having cleared funds in your account – auction houses won’t accept pending transfers or credit card payments.

For a property with a guide price of £200,000, you’d need at least £20,000 available immediately for the deposit. You’ll also need to cover auction fees, which typically range from 2-3% of the purchase price.

Don’t forget to budget for legal fees, surveys, and any immediate work the property needs.

Legal Preparation Matters

Every auction property comes with a legal pack.

This contains essential documents like title deeds, local authority searches, and property information forms. Having your solicitor review this pack before bidding is essential – I’ve seen buyers face serious issues because they skipped this step.

Modern online auctions usually make these packs available digitally, while traditional auctions might require you to request them specifically. Either way, factor in the cost of a legal review – typically £300-500 well spent.

What Happens After Winning

The moment the auctioneer’s hammer falls, you’re legally committed to the purchase.

You’ll need to sign the contract and pay your deposit immediately. Your solicitor should already be familiar with the legal pack and ready to proceed with the purchase.

At this point you will have exchanged contracts, and then have 28 days to complete.

This is when having an experienced broker really proves valuable. We know exactly what lenders need and can keep everything moving within those tight deadlines. We’ll also coordinate with your solicitor to ensure all parties work towards the same completion date.

Working with the Right Team

The fast-paced nature of auction purchases makes professional support essential.

Your mortgage broker can access specialist lenders who understand auction purchases and work to tight deadlines. They’ll also help coordinate the various parties involved in your purchase.

Let me give you a recent example: We helped a client purchase a £300,000 commercial property at auction using a combination of personal funds and a commercial bridging loan. The entire process from winning the bid to completing the purchase took just 20 days – plenty of time within the deadline.

Avoiding Common Problems

Most auction purchase problems stem from inadequate preparation. The total cost always exceeds the purchase price – you’ll need to budget for auction fees (typically 2-3%), legal fees (£1,000-2,000), and any immediate repairs.

Also, be realistic about the property’s condition.

Auction properties often need work – sometimes substantial renovation. Make sure your finance allows for this, whether through additional borrowing or separate funds.

Planning Your Purchase

If you’re considering an auction purchase, start by speaking with a broker who understands this market. They can help assess your options and connect you with suitable lenders. The key is starting this conversation early – ideally at least two months before any auction you’re interested in.
