Down Valuation After an Auction: Funding the Shortfall Before Completion

The hammer fell. You paid the 10% deposit. Then, around day 10, the surveyor marked the lot below the price you bid.

Your original lender will now advance only against that lower figure. The shortfall is yours to find. The contract is already exchanged, the deposit is non-refundable, and you still have to complete inside 28 days.

We issue a term sheet within 24 hours in most cases, and drawdown typically runs about two weeks. What decides it is whether the asset and the exit still stand up.

What a down valuation does inside a 28-day auction completion

In England and Wales, the fall of the hammer is exchange of contracts. You then usually have 28 days to complete. Many buyers only instruct the lender's valuer after the auction, not before.

Auction contracts are almost always unconditional. There is no mortgage-out clause. That is why a down valuation is a funding problem, not a renegotiation.

When the report comes in light, a high-street lender cuts the advance to its LTV on the new figure. The gap is the difference between the balance you must pay and the money they will now send. A Decision in Principle issued before the auction is not a commitment once the valuer is below hammer.

Stamp Duty Land Tax is still charged on the price you actually pay, not on the valuer's number. Legal costs and any notice-to-complete risk sit on the same clock. For the pack solicitors should assemble from day one, see what lenders need to complete an auction purchase in 28 days.

How we size the loan after a down valuation

We lend against the asset and a credible exit, not against the bid you made in the room. That means the lower of cost and current market value, then an LTV cap of up to 75%. Terms are indicative and subject to valuation and due diligence.

Take a worked example. Hammer at £4 million, valuer at £3.4 million: we work from £3.4 million. At 75% that is £2.55 million, not £3 million, and the rest is equity you must show.

We are a direct private lender, not a bank. We do not apply income multiples. We do require KYC, source of funds, a Report on Title, and a first charge we can enforce. Auction bridging loans are built for this window; lots a high-street lender will not consider are assessed case by case, subject to terms.

If the buyer is a foreign national or an SPV, the original lender often steps away once the valuation slips. Foreign buyers seeking UK bridging still need the same asset quality and a clean exit. The passport does not change the LTV maths.

Closing the equity gap before notice to complete

The gap does not have to sit as cash in one account. Common routes:

• Cash or immediately available securities
• A smaller facility, with more equity on completion
• A staged drawdown, where the facility releases in tranches against an agreed schedule

We lend on a first charge over the auction asset only. HM Land Registry records that charge, and we will not lend against an asset we cannot register. Related: bridging finance for a London investment property shows how we sized a facility against a real London asset when the timetable was tight.

The lending process is short by design: term sheet in around 24 hours, then solicitors, valuation and drawdown. Typical drawdown is about two weeks, and urgent files can sometimes complete inside seven days.

A 28-day clock that is already on day 10 leaves little slack. If the file cannot be closed before a notice to complete expires, do not pretend otherwise.

When a bridging loan is the wrong tool

A bridge is the right tool when the valuation is defensible, the exit is real (refinance or sale inside 3–24 months), and you can fund the equity gap. It is the wrong tool when the valuer has marked the lot so far below hammer that even 75% of the lower figure, plus your cash, still cannot complete.

It is also the wrong tool if there is no exit. Rolled-up interest on a short tenor costs more than a term mortgage. You are buying time, not a cheap long-term loan.

The main risk is contractual. Miss completion and the seller can serve notice, keep the 10%, and claim losses if they resell lower. Do not use a bridge to bet that the market will catch the hammer price. Use it when the asset still clears at the valuer's number and you can evidence the balance.

The bottom line

The 28-day window does not pause for a light valuation. Size the loan off the figure in the report, fund the gap from equity, and treat the notice-to-complete date as the real deadline.
