How do I buy a House at Auction With a Mortgage?

The process of buying a house at auction tends to be quite different from purchasing a home through traditional methods, primarily because the time frame you have to order your affairs is far shorter. When buying a house at auction, it is imperative that you have everything in place to close the sale quickly and move into your new property.

In this article, we will answer the question; can you buy a house at auction with a mortgage? Discuss the benefits of using an independent mortgage advisor, and cover the process of buying a house at auction with a mortgage.

Can you buy a house at auction with a mortgage?

Yes. You must first meet a particular criteria in order to qualify for a mortgage on a house you don’t own, but it is completely possible. There are several aspects of your new property that must be considered when applying for a mortgage before buying, including whether the heating and water is running and functioning properly, else you may not be able to obtain a mortgage in principle.

A mortgage in principle is the term for a mortgage on a house you don’t yet own that will provide a comprehensive overview of your current household funds to determine how much you could realistically afford to pay for a property, and the amount your lender would give you. It is vital to have a mortgage in principle in place when buying a house at auction so you can set restrictions on your bid on the day of auction.

Additionally, a mortgage in principle will act as evidence of your feasible affordability. 

  • How do I apply for a mortgage in principle?

When applying for a mortgage in principle, you could choose to work with a mortgage broker (otherwise known as a mortgage advisor) or consult the lender directly. We recommend you consult an independent mortgage advisor to receive the fastest service and the best prices possible, as oftentimes, going direct can take longer. 

To create an accurate and comprehensive mortgage in principle, you will need to provide personal information, your previous addresses from the last three years, the details of your income and any contractually binding, or otherwise, monthly outgoings. Your independent mortgage advisor will also evaluate your credit history to determine whether you’re a suitable applicant using hard or soft checks. 

  • What are hard and soft checks?

Hard and soft checks are two methods of evaluating your creditworthiness. A soft check is a simple identification check which ensures that you are who you say you are and a basic check of credit history that includes credit cards, loans (excluding student loans), mortgages, phone contracts, previously rented properties and car finance. However a hard check is a more in-depth analysis of your credit history and too many can impact on the way a lender looks at you as a risk.

Should you apply to several mortgage brokers (or lenders), who each conduct hard checks, regardless of their outcome, your repeat hard checks will remain on your report for up to two years and could result in a lessened credit score. It will be more difficult to obtain a mortgage in principle if you have a low credit score. So it is important to ensure your application is as perfect as possible before applying. We would always recommend finding a good independent mortgage broker who can look at all lenders for you and minimise the chance of rejection, also minimising the number of credit checks undertaken.

Why choose an independent mortgage advisor?

Independent mortgage advisors search the mortgage market on your behalf to help you achieve the best rate possible. Additionally, they will help you formulate the perfect application for a mortgage in principal so the wait for approval is far shorter and has more chance of being accepted.

The process of buying a house at auction with a mortgage

Before buying a house at auction, be aware of the expiration date of your mortgage in principle. This document is only valid for between 30 and 90 days after the initial issue, and will need to be reapplied for if you exceed that date. Furthermore, be aware that even if you have a mortgage in principle for a property, you may find it difficult to obtain a mortgage if you intend to buy a house with a non-standard structure, a presence of Japanese Knotweed, or serious defects. 

Buying a house at auction requires you to pay the full 10% deposit very soon after the auction ends (unless agreed otherwise), if you have attended an unconditional auction. Failure to comply could result in losing your deposit and the expectation to pay the costs for the resale of the property at a future auction. Additionally you will be expected to complete the purchase very quickly, not doing so will incur costs and/or loss of the deposit too.

It is imperative that you start the process to convert your mortgage in principle to a full mortgage, have it finalised and offered, conduct a property survey, engage with solicitors, acquire insurance, and complete any further paperwork. The most important thing to assess before buying at auction is whether a mortgage can be obtained on the property given its condition and mortgage-ability, even having an agreement in principle wont guarantee this.
