Can You Get a Mortgage on an Auction Property?

24th Jun 26 · Last updated 3rd Nov 26 · 7 MIN READ

Yes, you can use a mortgage to buy at auction, if it can complete in time. Here is when a mortgage works, how the 28 and 56-day deadlines differ and when bridging finance is the better route.

Your home or property may be repossessed if you do not keep up repayments on a loan secured on it.

Mortgage on Auction Property

Yes, you can get a mortgage on an auction property, but only if the lender can value the property, approve it and release the money before your completion deadline. At a traditional auction that deadline is usually 28 days after the hammer falls, which is tight for a mortgage. At a modern method auction you usually have 56 days, which is often enough. If the timing or the property does not suit a mortgage lender, buyers use cash or a short-term auction bridging loan and then remortgage once they own the property.

Which type of auction is it?

The first thing to check is the auction type in the listing, because it decides how long you have to raise the money. Every auction sets its own terms, so read the special conditions in the legal pack too: some traditional auctions allow more than 28 days and some modern method auctions allow less than 56.

Traditional auction vs modern method of auction
Traditional (unconditional) auctionModern method of auction (conditional)
When contracts are exchangedWhen the hammer fallsUsually within 28 days of the auction
Payable on the dayUsually a 10% deposit, plus any buyer's feesA non-refundable reservation fee, plus the deposit when you exchange
Time to completeUsually 28 days, sometimes 20 working daysUsually a further 28 days after exchange, about 56 in total
Is a mortgage realistic?Possible if the mortgage is fully prepared in advance and the property is straightforwardOften, for standard homes and buy-to-lets
If you cannot completeYou can lose the deposit and be pursued for the seller's lossesYou can lose the reservation fee, and the deposit too once you have exchanged

Will a mortgage work for your auction purchase?

A mortgage is usually workable when most of the following are true:

  • It is a modern method auction, or a traditional auction with at least 28 days to complete.
  • The property is habitable, with a working kitchen and bathroom, and of standard construction.
  • You have a mortgage in principle from a lender that will value the property quickly.
  • Your deposit covers at least the 10% due on the day plus any gap if the valuation comes in low.
  • Your solicitor has checked the legal pack and found nothing that would worry a lender.

You will probably need cash or bridging finance if any of these apply:

  • The property is uninhabitable, for example with no kitchen, structural problems or damp severe enough that a lender would retain money or decline.
  • It is of non-standard construction, has a short lease, sits above commercial premises or has title problems.
  • You plan to refurbish, convert or split it before letting or selling.
  • Completion is due in 28 days or less and you have not already started the mortgage application.

Lenders are wary of auction properties because many are sold at auction for a reason, such as condition, a short lease or a probate or repossession sale. See our guide to mortgages for unusual properties for the property types that need a specialist lender.

How to buy a house at auction with a mortgage

The work happens before the auction. Once you have won, there is too little time to start.

Timeline for a traditional auction with a 28-day completion
WhenWhat to do
2 to 4 weeks beforeGet a mortgage in principle, check how much you can borrow and ask the lender or broker whether they can meet a 28-day completion on an auction purchase.
1 to 2 weeks beforeView the property, get a survey if possible and have a solicitor review the legal pack and special conditions.
Auction dayBid within your limit. If you win, you exchange and pay the 10% deposit and any fees there and then.
Days 1 to 3Submit the full mortgage application and book the lender's valuation straight away.
Weeks 1 to 3Valuation, underwriting and the mortgage offer. Two to four weeks is typical once everything is in.
By day 28The lender releases the funds to your solicitor and you complete. If the offer is not ready, a bridging loan is the usual fallback.

With a modern method auction the steps are the same, but the 28 days to exchange give you time for the valuation before you are committed to the full deposit.

What if the valuation comes in below your bid?

The lender lends against its valuation, not the price you paid. If you bid £250,000 and the lender values the property at £230,000, a 75% mortgage is £172,500 rather than £187,500. You have to find the £15,000 difference in cash, on top of your deposit, before the completion date. Set your maximum bid with that risk in mind, especially for properties in poor condition or with few comparable sales.

What does buying at auction cost on top of the price?

Typical costs of an auction purchase
CostWhat to expect
DepositUsually 10% of the hammer price on the day at a traditional auction, often with a minimum amount
Buyer's premium or administration feeSet by the auction house and shown in the listing. Usually payable on the day
Reservation fee (modern method)Non-refundable and on top of the price. Check the amount in the listing
Seller's costs passed to the buyerSome legal packs ask the buyer to repay the seller's searches or legal fees
Stamp Duty Land TaxNormal rates apply, including the surcharge on additional properties (see gov.uk)
Legal, survey and lender feesYour solicitor, a survey, and the mortgage or bridging arrangement and valuation fees

Using a bridging loan to buy at auction

Most auction buyers who do not pay cash use a bridging loan. A bridging lender can often complete within days, will lend on properties a mortgage lender would decline and looks mainly at the property and the exit, which is how you will repay. The usual exit is a remortgage or a buy-to-let mortgage once the purchase has completed and any works are done, or the sale of the property.

Bridging costs more than a mortgage. Interest is quoted monthly, there is usually an arrangement fee of 1% to 2% and there may be exit and valuation fees, so it suits a short period with a clear exit. Read how auction finance works, how quickly a bridging loan can be arranged, or see our Auction finance page for rates and loan-to-value limits.

Enness case study: a £300,000 auction purchase

Short-term finance for a property auction purchase
The dealDetail
Purchase price£300,000
Client's cash£140,000
Bridging loan£160,000, about 53% loan to value
Rate and term0.58% a month over 12 months
ExitRefinancing agreed as part of the arrangement

The client had already committed to the purchase when their surveyor ran into problems. Enness helped resolve the survey and arranged the finance in parallel through private banking contacts, so the purchase completed within the deadline. Read the case study.

At 0.58% a month, interest on £160,000 is about £928 a month, or about £5,570 if the loan is repaid after six months. This is illustrative and excludes fees. On a larger scale, Enness has arranged a £1.9 million refurbishment bridged and then refinanced onto an investment mortgage.

Can first-time buyers get a mortgage on an auction property?

Yes, but it is harder. First-time buyers usually need a high loan to value, which leaves little room if the valuation is low, and they cannot normally use bridging finance on a home they will live in without a clear plan to repay it. A modern method auction on a property in good condition is the most realistic route. Have your mortgage in principle, deposit and solicitor in place before you bid.

Buy-to-let and refurbishment purchases

Landlords can use a buy-to-let mortgage for an auction property that is ready to let, as long as the rent covers the lender's stress test. Where the property needs work first, the common route is to buy with bridging finance, refurbish and then refinance onto a buy-to-let mortgage, often at a higher valuation. For owner-occupiers planning works, a renovation mortgage may be an option after completion. Unique property finance covers listed, non-standard and other properties mainstream lenders turn down.

Frequently asked questions

Can you get a mortgage on an auction property?

Yes, if the lender can value and approve the property before your completion deadline, which is usually 28 days at a traditional auction and about 56 days at a modern method auction. Properties in poor condition often need cash or a bridging loan instead.

How long do you have to pay for an auction property?

At a traditional auction you pay a deposit, usually 10%, on the day and the balance within the completion period, usually 28 days. At a modern method auction you usually have 28 days to exchange and a further 28 days to complete. The legal pack sets the exact deadline.

What is the modern method of auction?

The modern method of auction is a conditional auction. The winning bidder pays a non-refundable reservation fee, then usually has 28 days to exchange contracts and a further 28 days to complete. The extra time makes a mortgage more realistic than at a traditional auction.

Can I get a mortgage in 28 days?

Sometimes. A mortgage offer typically takes two to four weeks once the application and valuation are in, so it can work if you have a mortgage in principle, the property is straightforward and you apply the day after the auction. Many buyers arrange a bridging loan as a backup.

What happens if my mortgage is not ready by the completion date?

If you cannot complete on time, you can lose your deposit and the seller can pursue you for their losses, such as interest and the cost of reselling. Arranging a bridging loan to complete, then remortgaging, avoids this.

What deposit do I need to buy at auction?

Usually 10% of the hammer price on the day, plus any buyer's fees. Your mortgage deposit may need to be larger, typically 25% for a buy-to-let, and you need extra cash if the lender's valuation is below your bid.

Why won't lenders mortgage some auction properties?

Lenders decline properties that are uninhabitable, of non-standard construction, have short leases, structural problems or title issues, or are above commercial premises. Many auction properties fall into one of these groups, which is why they are sold at auction.

Can you buy a house at auction with a mortgage as a first-time buyer?

Yes, if the property is in good condition and there is enough time to complete. A modern method auction is usually more realistic for first-time buyers than a traditional 28-day auction.

Can I remortgage straight after buying at auction?

Yes. Many buyers complete with a bridging loan and then remortgage. Some lenders want you to have owned the property for six months before lending on a higher value, so check this before you rely on refinancing at a higher valuation.

Is a bridging loan more expensive than a mortgage?

Yes. Bridging interest is charged monthly and there are arrangement, valuation and sometimes exit fees, so it is used for months rather than years. It is designed to be repaid by a sale or a mortgage.
