Commercial Auction Finance Guide: Funding Property Bought at Auction
Buying commercial property at auction can deliver outstanding value. Auction properties often sell below market value because sellers need a quick, certain sale. But the auction process comes with a critical constraint: once the hammer falls, you typically have 28 days to complete. Standard commercial mortgages take 6-12 weeks. That mismatch means auction buyers need a different financing strategy.
At Commercial Mortgages Broker, we arrange auction finance for commercial property across the UK. Whether you need bridging finance to meet the 28-day deadline or want to plan your exit strategy before you bid, this guide explains exactly how to approach commercial auction finance.
How Commercial Property Auctions Work
Understanding the auction process is essential for planning your finance.
Traditional Auctions
The property is offered at a live auction (in person or online). Once the auctioneer's hammer falls, the successful bidder:
- Pays a 10% deposit immediately (on the day or within 24 hours)
- Signs a binding contract to purchase
- Must complete the purchase within 28 days (the standard completion period)
- Forfeits the deposit and faces potential legal action if they fail to complete
The 28-day completion deadline is the defining challenge. You cannot exchange at auction and then spend 8 weeks arranging a mortgage.
Modern Method of Auction (MMoA)
A newer format where the successful bidder pays a reservation fee (typically 4-6% of the purchase price) and then has 28-56 days to complete. This format provides more time and is less binding than traditional auction, though it still requires rapid finance.
Conditional vs Unconditional Sales
Most traditional auction sales are unconditional: once the hammer falls, you are committed. Some auctions offer conditional sales where the exchange of contracts is deferred, giving more flexibility. Always check the terms of sale for each lot.
Why Auction Finance Is Different
Auction finance is fundamentally about speed and certainty. The standard commercial mortgage process is too slow for auction completion deadlines, which means bridging finance is the primary tool for auction buyers.
The Speed Requirement
| Finance Type | Typical Timeline | Suitable for Auction? |
|---|---|---|
| Commercial mortgage | 6-12 weeks | No (too slow) |
| Bridging finance | 5-21 days | Yes |
| Cash purchase | Immediate | Yes (if available) |
| Development finance | 8-16 weeks | No (too slow) |
Bridging finance can complete within 5-21 days, well within the 28-day auction deadline. This is why the vast majority of auction purchases are funded with bridging loans, even when the buyer intends to refinance to a commercial mortgage shortly afterwards.
Pre-Auction Preparation
The most successful auction buyers arrange their finance before they bid. This means:
- Identifying the property in the auction catalogue (typically published 2-4 weeks before the auction)
- Conducting due diligence on the property (viewing, legal pack review, comparable research)
- Obtaining an Agreement in Principle from a bridging lender before auction day
- Having your solicitor review the legal pack and title before you bid
- Confirming your deposit is available and accessible
Buying at auction without pre-arranged finance is extremely risky. If your finance falls through, you lose your deposit and face potential legal action from the seller.
Bridging Finance for Auction Purchases
Bridging finance is the standard tool for auction property purchases. Here is how it works in the auction context.
How Bridging Works
A bridging loan is a short-term, secured loan designed for speed. The lender takes a first legal charge on the property and provides funds quickly, often within 7-14 days of receiving the legal pack.
Typical Bridging Terms for Auction
| Factor | Typical Range |
|---|---|
| LTV | 65-75% |
| Monthly interest rate | 0.55-1.2% |
| Term | 6-18 months |
| Arrangement fee | 1-2% |
| Exit fee | 0-1% |
| Minimum loan | £50,000-£100,000 |
| Speed | 5-21 days to completion |
Annual Cost Comparison
Bridging finance is more expensive than a long-term commercial mortgage, but it is designed for short-term use. The cost is justified by the access to below-market-value auction purchases.
Example: £300,000 bridging loan at 0.75% monthly rate for 6 months:
- Monthly interest: £2,250
- Total interest (6 months): £13,500
- Arrangement fee (1.5%): £4,500
- Total cost: £18,000
If the property was purchased at a 15-20% discount to market value at auction, the bridging costs are well covered by the acquisition saving.
What Bridging Lenders Assess
- Property value: Independent valuation or desktop assessment
- Exit strategy: How you will repay the bridging loan (refinance to commercial mortgage, or sale)
- Borrower profile: Credit history, experience, assets
- Legal title: Clean title with no blocking issues
- Speed requirement: How quickly the funds need to be released
The Auction Finance Process: Step by Step
Before the Auction
**4-3 weeks before**: Identify lots of interest in the auction catalogue. Request legal packs from the auctioneers.
**3-2 weeks before**: View the property. Instruct your solicitor to review the legal pack. Research comparable values to set your maximum bid.
**2-1 weeks before**: Contact your broker to obtain an Agreement in Principle for bridging finance. Confirm your deposit is available. Complete any lender paperwork that can be done in advance.
**1 week before**: Confirm your finance is in principle agreed. Ensure your solicitor is ready to act immediately after the auction. Review any updates to the lot details.
Auction Day
**Before bidding**: Confirm your maximum bid based on your valuation, finance costs, and planned exit. Do not exceed this limit in the heat of the moment.
**Winning bid**: Pay the 10% deposit (by bank transfer or banker's draft, as specified in the auction terms). Sign the contract. Notify your broker immediately.
After the Auction (Days 1-28)
**Day 1-2**: Broker formally submits the bridging application with full documentation. Solicitor begins legal work.
**Day 3-7**: Lender instructs valuation (if not already done). Many auction bridging lenders use desktop or drive-by valuations for speed.
**Day 7-14**: Valuation received. Lender issues formal offer. Solicitors exchange any remaining information.
**Day 14-21**: Legal work completed. Lender releases funds to solicitor.
**Day 21-28**: Completion. Funds transferred, property ownership changes. You now own the property.
This timeline is achievable with a well-prepared application. Without preparation, squeezing everything into 28 days becomes extremely stressful and risky.
Exit Strategy: Refinancing After Auction
Bridging finance is a temporary solution. Your exit strategy, how you repay the bridging loan, is critical.
Refinance to a Commercial Mortgage
The most common exit strategy. Once you own the property and any necessary works are completed:
- Instruct your broker to arrange a long-term commercial mortgage
- The commercial mortgage lender values the property (at current market value, which should be above the auction purchase price)
- The commercial mortgage pays off the bridging loan
- You have a long-term facility at much lower rates
Timeline: Start the commercial mortgage process within the first month of the bridging loan to avoid unnecessary interest costs.
Refinance After Adding Value
If the auction property needs refurbishment or repositioning:
- Complete works during the bridging term (6-12 months)
- Apply for a commercial mortgage based on the improved property value
- The higher post-works value may allow you to recover some or all of your initial investment through the refinance
This is the classic value-add auction strategy and can generate excellent returns.
Sale
Some auction buyers plan to sell the property rather than hold it:
- Sell the property at market value (above the discounted auction price)
- Repay the bridging loan from the sale proceeds
- Retain the profit
Sale as an exit strategy is acceptable to bridging lenders, though most prefer refinance as it is within the borrower's control (sale depends on finding a buyer).
Types of Commercial Property at Auction
Auction catalogues feature a wide range of commercial property:
Most Common Auction Lots
- Retail units with tenants: Often sold at auction when landlords want a quick sale
- Mixed-use buildings: Shops with flats above, particularly popular at auction
- Vacant commercial property: Requiring refurbishment or change of use
- Industrial and warehouse units: Both tenanted and vacant
- Land with planning permission: Development opportunities
- Repossessions: Properties sold by lenders or receivers
Auction Opportunities
Auction properties are sold at a discount because the seller prioritises certainty and speed. Common reasons properties end up at auction:
- Repossession by lenders
- Estate sales and probate
- Portfolio rationalisation by institutional sellers
- Properties that are difficult to sell on the open market (unusual types, condition issues, complicated legal titles)
- Sellers who need funds quickly
The discount typically ranges from 10-25% below open market value, though it varies enormously by lot and market conditions.
Costs of Auction Finance
Budget for the full cost of the auction purchase, not just the property price:
| Cost | Amount |
|---|---|
| Property price | Your successful bid |
| Auction deposit (10%) | Payable on the day |
| Buyer's premium (if applicable) | 0-2% (some auctioneers charge) |
| SDLT | Standard rates |
| Bridging arrangement fee | 1-2% of loan |
| Bridging interest (6 months) | 3.3-7.2% of loan |
| Bridging valuation | £500-£2,000 |
| Legal fees (bridging) | £2,000-£5,000 |
| Legal fees (purchase) | £2,000-£5,000 |
| Refinance costs (later) | Arrangement fee + valuation + legal |
Example Total Cost
For a £250,000 auction purchase at 70% LTV bridging:
- Deposit (30%): £75,000
- Auction deposit (10% of £250,000): £25,000 (part of the 30%)
- SDLT: approximately £7,500
- Bridging arrangement fee (1.5% of £175,000): £2,625
- Bridging interest (6 months at 0.75%): £7,875
- Legal and valuation: approximately £6,000
- Total upfront costs: approximately £99,000
Plus refinance costs of approximately £10,000-£15,000 when moving to a commercial mortgage.
Risks and How to Manage Them
Bidding Risk
**Risk**: Overpaying in the heat of the auction. **Mitigation**: Set your maximum bid before the auction based on objective valuation and do not exceed it. Factor in all finance and refurbishment costs.
Finance Risk
**Risk**: Bridging finance not completing within 28 days. **Mitigation**: Arrange finance in principle before bidding. Use a specialist auction finance broker and an experienced solicitor. Do not bid unless you have high confidence that finance will complete.
Hidden Defects
**Risk**: Discovering problems with the property after purchase. **Mitigation**: Review the legal pack thoroughly before bidding. View the property in person. Commission a building survey if the lot is high value.
Exit Strategy Risk
**Risk**: Unable to refinance to a commercial mortgage within the bridging term. **Mitigation**: Ensure the property is financeable with a long-term lender before buying. Get indicative terms for the refinance at the same time as arranging the bridge.
