Auction Bridging Loan: Fast Finance for Property Auctions

Buying property at auction is one of the best ways to secure a below-market value property as well as access a wider range of available properties. In recent years, property auctions have moved away from the specialist market of unmortgageable properties and repossessed homes, and now cover a wide range of opportunities.

Auction finance is a fast, flexible short-term bridging loan designed to meet the 28-day completion deadline for auction purchases when a traditional mortgage cannot. For property buyers including homeowners, landlords, developers, and investors, it can make the difference between securing an auction property and losing it because the funding cannot be arranged in time.

This guide explains when auction finance is suitable, how auction bridging loans work, what they cost, which exit strategies lenders expect, and how Clifton Private Finance helps clients secure and manage funding for auction purchases, including properties that need refurbishment before they become mortgageable.

What Is Auction Bridging Finance?

Auction bridging finance is a type of short-term loan that is used to secure a property at auction, where traditional mortgage finance may be too slow to arrange in time. This is because property auctions typically have 28-day completion deadlines on sales once the hammer has fallen.

An auction bridging loan has two main considerations at its core:

• Speed
• Flexibility

The first need is clear: the requirement to make the final payment for auction purchases within 28 days means auction finance must be put in place quickly. But flexibility is also essential.

Many auction properties are considered unsuitable for traditional mortgages, often because they are in a state of distress that means they are classed as uninhabitable, but also if there are legal or other complications that put them outside many mortgage lenders’ tight criteria.

An auction bridging loan uses different methods of assessment for loan approval. It is a short-term loan that allows you to make the initial purchase at auction and is paid off by longer term finance or through a later property sale - a process known as the exit strategy.

Some common uses for auction finance include:

• Seizing a below-market value opportunity: Property auctions often present opportunities to buy a house at a discount where the current owners are looking for a quick sale and value expediency over maximising the purchase price. The ability to move quickly, knowing you have full financial backing, is essential to get in your successful bid.
• Buying a distressed property to live in: Many auction properties are in need of repair and renovation. These distressed properties are considered unmortgageable, and generally cannot be used to secure a traditional residential mortgage. Auction finance can provide the funding for both the property purchase and essential renovations, creating a bargain home that’s modernised to your exact tastes.
• House flipping: For investors, auctions provide a potential opportunity to make a considerable and quick return on investment. House flipping involves buying a property at a discount, often because it is unmortgageable, renovating and redeveloping it to a high modern standard, and then selling it on. Using auction finance, you can fund the full renovation project, using the proceeds from the final sale as an exit to repay the finance.
• Buy, Refurb, Rent, Refinance, Repeat (BRRRR): Landlords and property investors may use auction finance as part of the BRRRR process. This involves buying a property at auction, refurbishing it with an eye to current rental market needs, renting it out, and using a buy-to-let mortgage to refinance the project, which can then be repeated to build a larger portfolio of rental properties.

With auction finance, the challenges of buying a property at auction are easily overcome, allowing you to bid with confidence.

How Quickly Can You Get Auction Finance?

At Clifton Private Finance, our auction finance specialists work to secure bridging loans for clients as quickly as possible. A typical timeframe is 1-2 weeks, however in particular circumstances it is possible to secure approval on an auction bridging loan within 48-72 hours.

Obtaining a Decision in Principle

Auction finance is a staged process. The initial stage requires obtaining a Decision in Principle (DIP), which is the lender’s basic agreement that they will provide the auction loan assuming all the supplied details are correct. A DIP happens before the more detailed underwriting of the loan, allowing it to be offered quickly, and is well-suited to a buying property at auction.

Once you have the DIP in hand, you can move forward to the auction, placing your bid with the confidence that you have a lender’s backing.

Full Auction Bridging Loan for Property Purchase

The sum of your auction finance becomes available once the full asset-valuation and underwriting is complete. The auction deadline for completion is typically 28 days, and auction finance is structured to meet this deadline smoothly, ensuring you do not risk your auction deposit.

In traditional auctions, a standard residential mortgage often takes 4 to 6 weeks to process, so if you do not already have a mortgage offer in place, faster funding is usually the safer route.

Development and Renovation Funds

In some circumstances, auction finance can be structure with a staged drawdown, providing additional funds for renovation work as-and-when needed. By drawing on these funds only when needed, interest is reduced and the auction finance is more cost-effective.

Staged drawdowns occur at pre-defined milestones, as arranged with the lender.

How Does Auction Finance Work?

Auction finance is a short-term loan that is secured through property assets. Unlike a traditional mortgage that is limited by affordability checks and loan-to-value against the primary property alone, auction finance focuses on one-or-more property assets for security.

Auction finance typically has no monthly repayments, but is repaid as a single sum through an exit strategy. This exit is usually either:

• Refinancing with a traditional mortgage: Once the auction property is purchased with a bridging loan, a mortgage is taken out to repay the bridging loan and you move onto a traditional monthly repayment model
• Proceeds from the sale of a property: This can be the auction purchase itself, as part of a house flipping project, or a pre-existing property as is typically the case in downsizing or relocation scenarios

Borrowing Limits and Loan-to-Value

The maximum amount of finance you will be able to secure is based on a loan-to-value (LTV) calculation. For many specialist auction finance lenders, this is typically 65%-75%.

At Clifton Private Finance we have established relationships with many auction finance specialists, and can explore larger LTV options, including those as high as 85% LTV in some circumstances.

As an illustrative example, Ted is looking to buy a distressed house at auction with a reserve price of £240,000. He is a homeowner with a property valued at £400,000 that still has an existing mortgage balance of £120,000 attached to it.

The full property value that Ted is offering as security is:

• £240,000 from the auction property
• £280,000 equity from his home
• Total of £520,000 total security value

With this £520,000 security, Ted obtains auction bridging finance at 75% LTV. The total bridging loan sum equals £390,000.

This provides Ted with enough funds to comfortably:

• Bid on the property and pay for it outright (£240,000)
• Budget for renovations of £90,000
• Cover stamp duty and legal fees
• Factor in interest, arrangement fees, and broker fees

After renovating the house, Ted sells it on, executing his planned exit strategy. He obtains £445,000 for the modernised house, repaying his bridging in full and providing him with a reasonable return on investment.

Lender Underwriting

When evaluating the auction finance application, lenders will typically consider, with underwriting assessed individually depending on the property, borrower, and exit plan:

• The property itself: While auction finance is good for unmortgageable properties, lenders will still consider condition, construction type, location, and marketability in valuations
• LTV ratio: This can be calculated against the auction property alone, or against a wider spread of property assets and equity to increase the final loan maximum
• Security valuation: An independent valuation may be required on all assets used as security
• Borrower experience: This is especially important for renovation projects, where prior experience in construction and refurbishments improves the chance of approval. For larger refurbishments or ground-up schemes, lenders may also review project viability, including costs and timelines
• Credit history: While auction finance is less focused on credit score than a mortgage, it is still considered. At Clifton Private Finance, we work with many lenders who understand if you have a poor credit history, ensuring ‘bad credit’ is not a roadblock to your property ambitions
• Source of funds: Lenders must perform due diligence when evaluating your deposit, with checks for fraud and money laundering
• Legal due diligence: All auction finance loans require legal work to check for title issues, restrictions, lease length where applicable, occupancy status where there are tenants in situ, and more
• Exit strategy: Of all the lender checks, evaluating your exit strategy is often the most important

Exit Strategies: How to Repay an Auction Bridging Loan

The exit strategy is a core component to auction finance. Unlike long-term property finance, such as a residential mortgage, auction finance is a ‘bridge’ between the need for money today, and the understanding that it can be repaid in a single lump sum after a planned event.

1. Refinancing with a Mortgage

Refinancing with a mortgage may be used when the property is for:

• Residential use, where you or a close family member intends to live in the property
• Commercial use, where you intend to use the property for business purposes, with a commercial mortgage
• Rental as a buy-to-let (known as a bridge-to-let strategy), with a buy-to-let mortgage
• Conversion and investment, such as converting a large family home into a HMO, with an HMO mortgage

In some circumstances a specialist mortgage may need to be arranged in advance to provide the required confidence for the auction finance lender.

At Clifton Private Finance, our auction bridging loan team work closely with our mortgage specialists to ensure a smooth handover, building a suitable refinance exit strategy for your auction purchase.

2. Sale

Investors looking to use auction finance to buy bargain properties with a view to renovation, conversion, or other development, will have an exit strategy centred on selling the property on for a profit.

This is commonly known as ‘house flipping’, though it is equally viable with commercial property, where it is known as a ‘bridge to develop’ strategy.

House flipping may involve more complex auction finance, that combines the cost of buying the property at auction with the refurbishment costs. A detailed proposal will be needed for the lender, that includes the renovation budget and research regarding the expected final sale value of the property.

Auction finance that includes renovation typically has a longer term to consider the time required, with loan terms up to 18 months.

3. Alternative Funding

Other forms of exit are also possible. These may include:

• The sale of another property: This could be your current home, which is sold to pay the auction finance once the new property is renovated and brought to your desired standard
• Money coming from inheritance: In circumstances where funds are currently in probate or an inheritance is clear, this can be used as an exit
• Capital from sale of shares or other assets: When money is coming from another source, such as shares that are due to be sold when their market value peaks, or other high-value assets that are in their respective markets, lenders may accept this as an appropriate exit plan

Your Clifton Private Finance auction finance adviser will work with you to explore your exit strategy options and ensure the right plan for your lender.

Auction Finance Rates and Fees: How Much Does It Cost?

Auction bridging finance costs include:

• Broker fee: Clifton Private Finance’s award-winning, independent service is covered with a fixed £995 fee
• Lender’s arrangement fee: typically 2% of the net loan amount
• Valuation fee: Using online valuation tools, we aim to keep this fee as low as possible while ensuring an accurate assessment of the property’s value. In many cases, this is the main upfront cost at the start of the loan process. In some cases, the valuation fee may be reduced to zero. Some circumstances, such as multi-property security, may require third-party valuations with additional costs
• Legal fees: In most cases, solicitor’s fees range from £800 to £1,000
• Interest: We work with a range of lenders to find you the most competitive interest rates

At Clifton Private Finance we offer competitive auction finance interest rates.

Auction finance interest rates are calculated monthly and depend on circumstances, with rates starting from 0.51% per month, subject to status and security, and higher rates for higher LTV loans. Rates are typically higher than standard mortgages because auction finance is short term and fast-moving.

Interest Structures for an Auction Bridging Loan

Interest on your auction finance can be structured in different ways to suit your circumstances, allowing you to plan your exit strategy accordingly.

• Rolled-up interest: Interest accrues during the length of the loan and is added to the balance to be repaid at exit.
• Retained interest: Interest is calculated upfront and deducted from the gross loan prior to capital release. This can lead to easier end-of-term loan calculations for refinancing with a mortgage.
• Serviced interest: Interest is calculated and paid through regular monthly interest payments. Like retained interest, servicing the interest during the term results in a clearer auction loan total at the end of the term.

Discuss your interest payments with the auction finance team at Clifton Private Finance to ensure the loan fits your circumstances, prior to finalising your auction finance agreement.

6 Scenarios Where an Auction Property Loan Is Suitable

1. Residential Auction Purchase

When you are looking for a new property to live in, auction finance opens the door to a wide range of possibilities. As auctions become more popular, more and more estate agents are using them to sell properties faster, and some stock is sold this way because it would be harder to place on the open market in its current condition, leading to a larger market of suitable homes, including many with a discounted price that just need a little refurbishment.

With a traditional residential mortgage application and underwriting process typically too slow to meet the tight 28-day deadline of traditional auction houses, auction finance offers a powerful solution:

• Find a new home in the wider auction market
• Secure auction finance decision in principle in under 72 hours with Clifton Private Finance, based on the reserve price of the property
• Bid in the auction
• Enjoy a win with a confident successful bid
• Finalise your auction finance
• Purchase the property in plenty of time for the traditional 28-day auction deadline
• Complete and get the keys to your new home
• Renovate if required
• Secure a mortgage with Clifton Private Finance to pay off your auction finance and switch to regular monthly repayments

We’re here at Clifton Private Finance to help you through every stage of your home buying experience, from traditional auction bridging loans to fast-application mortgages for MMoA (Modern Method of Auction), and full mortgage-based refinancing for the auction finance exit.

2. Buy-to-Let Auction Purchase

Landlords exploring auction houses for rental property investments may find properties at below market value.

As with residential properties, potential landlords often find themselves stifled with traditional buy-to-let mortgage application lengths and traditional lenders’ more restrictive criteria.

Auction finance offers a way to move quickly, ensuring opportunities are not missed, and provides the essential extra time needed to secure a long-term buy-to-let mortgage at a lower interest rate.

This process of using bridging finance to provide capital while smoothing buy-to-let mortgage complications is often known as bridge-to-let, and represents a well-established strategy for professional landlords. It may also provide the basis for a wider BRRRR strategy, where properties are repeatedly bought and renovated to add to a portfolio.

Alternatively, landlords may consider Modern Method of Auction (MMoA) auctions which offer a longer 56-day completion window. In some cases, this provides a timeline where bridging is not needed and a buy-to-let mortgage can be arranged quickly enough, though landlords should take care to understand the nuances of MMoA before proceeding.

3. Renovation and Refurbishment Loan for an Auction Property

A specific renovation project can often have the refurbishment finance incorporated into the auction finance, providing a larger loan that covers both the property purchase and the renovation budget. These can be used:

• To purchase and renovate residential property to live in
• To purchase and renovate residential property to let
• To purchase and renovate residential property to sell

Clifton Private Finance is here to help you at every stage of a renovation project, from the initial auction finance through to your exit strategy and final settlement.

4. HMO Conversion of an Auction Property

Investors can use HMO bridging finance, secured with additional property assets, to provide the greater level of funding needed for an HMO conversion. This can maximise the rental potential for a property, increasing its viability as an investment.

Our expertise at Clifton Private Finance can support you through the process:

• Securing fast auction finance for the property purchase and conversion budget
• Developing specialist HMO mortgage-based exit strategy
• Providing staged drawdowns if required to reduce interest
• Supporting the conversion project with cash flow facilities if required
• Ensuring a smooth handover to our HMO mortgage specialists for exit

5. Development Finance for an Auction Property

Auction finance can also be used as an early purchase bridging loan for larger property development projects. This includes:

• Buying derelict properties that require substantial structural work
• Buying land purchases at auction for ground-up construction
• Development finance-based exit strategies

Once the required land or property is bought, Clifton Private Finance help you refinance the auction finance through a smooth exit to development finance which:

• Provides the capital required for the development work
• Sets staged milestones for drawdown to reduce accrued interest

Lenders will also review build costs and timelines before agreeing the development-finance exit.

When using development finance, additional considerations include:

• Ensuring planning permission is in place
• Mandatory quantity surveyor (QS) work, including site inspections, cost analysis, and drawdown scheduling
• Asset manager reviews

In these larger projects, the auction finance provides an essential early step, allowing you to secure the land or property before the opportunity is lost, and before essential QS reports and project details are approved.

With our teams working closely together, Clifton Private Finance can help you at every stage of your development, including:

• The initial auction finance as a property or land loan
• Development finance to provide essential working capital for construction
• Additional mezzanine finance support if required
• Full exit into mortgage-based refinance (residential, or buy-to-let) or property sale

6. Commercial Property Auction Purchase

Auction finance is suitable for business use to purchase or refinance commercial assets bought at auction, providing the initial purchase funds and additional capital to cover refurbishment costs, similar to residential auction purchases. With bridging loans for commercial property, additional considerations include:

• A potentially longer due diligence process
• Fewer automated valuations
• Use class regulations and planning permission
• Potential for mixed-use and semi-commercial complex properties

These extra complications can make bridging loans more suitable as securing an appropriate mortgage may be more difficult than expected.

Your dedicated broker will discuss the specifics of your commercial property purchase, helping you develop an appropriate funding plan and exit strategy.
