How do you finance a commercial property bought at auction?
Commercial auction purchases are usually funded with a bridging loan, because auctions require completion within a tight window — commonly 28 days — that a standard term mortgage often cannot meet. The bridge gets the deal completed on time, and is then refinanced onto a commercial mortgage or repaid from a sale once the property is mortgageable or improved.
The single most important rule of auction finance is to have it lined up before you bid. When the hammer falls you are legally committed, so there is no room to start arranging funding afterwards.
Why auctions need finance ready in advance
At auction, the fall of the hammer creates a binding contract. You will typically pay a deposit — often 10% — on the day, with the balance due on completion within the auction's stated period. Miss that deadline and you risk losing your deposit and facing further costs. This is why:
- You must know your maximum bid and that your funding covers it.
- You should have terms agreed in principle before the auction.
- The property should be assessed by your lender before you commit where possible.
How long do you have to complete?
The standard auction completion period is 28 days from the fall of the hammer, though it varies:
- 14 days — some lots require faster completion.
- 28 days — the most common window.
- 56 days — occasionally offered, which can allow a term mortgage.
Always check the legal pack and the special conditions for the exact timescale before you bid, because it dictates which type of finance is realistic.
Bridging versus mortgage for auction lots
Bridging is the default because it is fast and flexible, but not always necessary:
- Use bridging when the timescale is tight, or the property is vacant, dilapidated or otherwise not immediately mortgageable.
- A term mortgage may work when the completion window is longer, the property is in good order and let, and a lender can move quickly.
Many auction lots are sold precisely because they are problematic — vacant, in poor repair, or with title issues — which is exactly why bridging suits them. Our guide on commercial mortgage versus bridging explains how to choose.
What do you need to be auction-ready?
Before bidding, have:
- Your deposit funds available for the day.
- Finance agreed in principle covering your maximum bid.
- The legal pack reviewed by a solicitor.
- A clear exit plan for any bridge — refinance or sale.
- An idea of the property's condition and mortgageability.
How do you get auction finance ready fast?
Speed is everything at auction. Assesr builds a lender-ready credit paper from your figures in around 60 seconds and matches it to specialist lenders active in auction and bridging finance, so you can go into the room knowing your funding stacks up. You pay a 0.5% Assesr Fee on drawdown — a quarter of the typical broker fee — with nothing until completion.
Frequently asked questions
How do you finance a commercial property bought at auction?
Usually with a bridging loan, because auctions require completion in a short window that a term mortgage often cannot meet. The bridge is then refinanced onto a commercial mortgage or repaid from a sale once the property is mortgageable or improved.
How long do you have to complete an auction purchase?
Typically 28 days from the fall of the hammer, though some auctions allow 14 or 56 days. You are legally committed once the hammer falls, so funding must be arranged in advance and cover your maximum bid.
Can I use a commercial mortgage for an auction purchase?
Sometimes, if the property is mortgageable and the lender can move fast enough, especially where a longer completion window applies. But many auction lots are unmortgageable or the timescale is too tight, so bridging is the common route.
