One of the biggest questions people ask is: Can you buy an auction property with a mortgage? The short answer is yes—but the process is slightly different from buying through an estate agent.

At Smart Auction UK, we help buyers navigate auction purchases every day, including those using mortgages. In this guide, we’ll explain how buying with a mortgage works, what to expect, and how to make the process as smooth as possible.

Yes, You Can Use a Mortgage – But Timing is Key

Most people assume that auction purchases require cash because of the tight completion deadlines—usually 28 days. However, it is possible to buy with a mortgage, provided you’re prepared and move quickly.

The key to securing an auction property with a mortgage is ensuring that:

• The property is mortgageable (some aren’t—more on this later).
• You have a mortgage in principle before bidding.
• You can meet the tight auction completion deadline (usually 28 days).

Let’s break it down step by step.

Step 1: Get a Mortgage in Principle

Before even considering bidding at auction, you should speak to a mortgage lender or broker and get an Agreement in Principle (AIP). This document confirms how much a lender is likely to loan you, based on your income, credit score, and financial situation.

Having an AIP does not guarantee your mortgage will be approved, but it gives you a clear idea of your budget and reassures sellers that you’re a serious buyer.

Top Tip: Choose a lender that is experienced with auction purchases, as some banks won’t be able to process a mortgage in time.

Step 2: Check the Property’s Mortgageability

Not all auction properties are mortgageable. Some common red flags that might make a property difficult to mortgage include:

• Structural issues (cracks, subsidence, damp).
• Short lease (less than 70 years remaining).
• Non-standard construction (e.g., timber or concrete houses).
• Missing kitchen or bathroom (lenders require a property to be habitable).

Before bidding, it’s crucial to check the legal pack provided by the auction house and, ideally, have a survey done.

Smart Auction UK Tip: If you’re unsure whether a property is mortgageable, speak to a broker or lender before bidding.

Step 3: Bid with Your Deposit Ready

If you win the auction, you’ll need to pay a deposit immediately—typically 10% of the purchase price—on the same day. This is non-refundable, so you must be confident you can secure the mortgage.

Step 4: Move Fast with Your Mortgage Application

Once you’ve won the auction, you usually have 28 days to complete the purchase. This is much shorter than the traditional property-buying timeline, so you need to act fast.

Here’s what happens next:

1. Submit your full mortgage application immediately.
2. The lender will arrange a survey and valuation of the property.
3. Once approved, you’ll receive a formal mortgage offer.
4. Your solicitor will complete legal checks and handle the exchange of contracts.
5. The mortgage lender releases funds, and the sale completes.

If your mortgage isn’t approved in time, you risk losing your deposit—so speed is essential.

What If Your Mortgage Won’t Be Ready in Time?

If you’re struggling to meet the 28-day completion deadline, there’s an alternative: bridging finance.

A bridging loan is a short-term loan that allows you to complete the purchase while waiting for your mortgage. Once your mortgage is approved, you repay the bridging loan.

Bridging finance can be more expensive than a standard mortgage, but it ensures you don’t lose your deposit due to delays.
