How to Buy Property at Auction

Share:

Buying at auction can be an excellent way to secure property below market value, but it requires preparation and fast finance. This guide covers everything you need to know about auction purchases and how bridging loans make them possible.

Why Buy at Auction?

Property auctions offer several advantages:

  • Below market value - Properties often sell 10-30% under market price
  • Speed - Exchange happens immediately, completion in 28 days
  • Certainty - Once the hammer falls, the sale is legally binding
  • Variety - Repossessions, probate sales, and unusual properties

However, you need finance arranged before bidding. Traditional mortgages take 6-8 weeks - too slow for the 28-day completion deadline.

The Auction Timeline

Day 0: Hammer falls - you've won!
Immediately: Pay 10% deposit + buyer's premium
Days 1-7: Instruct solicitors, arrange valuation
Days 7-21: Legal work, lender underwriting
Day 28: Completion deadline - funds must be transferred

Miss the deadline and you lose your 10% deposit plus face potential legal action. This is why having finance pre-agreed is essential.

How Bridging Loans Work for Auctions

Bridging loans are designed for speed. Here's the typical process:

  1. Pre-approval - Get a Decision in Principle before the auction
  2. Win the bid - Pay your 10% deposit on the day
  3. Formal application - Submit full details to your chosen lender
  4. Valuation - Lender instructs a surveyor (often within 48 hours)
  5. Legal work - Faster than mortgages as fewer checks required
  6. Completion - Funds released, typically within 2-3 weeks

What You Need Before the Auction

  • Decision in Principle - From a bridging lender, not a mortgage lender
  • Proof of deposit - 10% of maximum bid price in accessible funds
  • Solicitor on standby - Ideally one experienced in auction purchases
  • Exit strategy - How will you repay? Sale or refinance?
  • Legal pack review - Have your solicitor check this before bidding

Typical Auction Bridging Costs

For a £300,000 auction purchase with 75% LTV bridging loan (£225,000):

Monthly interest (0.55%)£1,237/month
Arrangement fee (2%)£4,500
Valuation fee£500
Legal fees (lender)£1,500
Your legal fees£1,500

Total upfront costs: approximately £8,000 plus monthly interest. Compare this to potentially saving £30,000-50,000 on purchase price.

Common Auction Mistakes to Avoid

  1. Not reading the legal pack - Hidden issues can be costly
  2. Relying on a mortgage - They simply won't complete in time
  3. Overbidding in the heat of the moment - Set a maximum and stick to it
  4. Forgetting buyer's premium - Usually 2-3% on top of hammer price
  5. No exit strategy - Know how you'll repay before you bid
