To acquire a property at auction, you will need to make a deposit of at least 10% to the auction house. You will then need to introduce a further 10% to 15% deposit to secure bridging finance. The further deposit is normally from business funds or individual personal savings. Some lenders are prepared to place a charge against other property owned if there is enough equity and the property is a suitable asset. This means that business funds or personal savings remain available to support cash-flow or any refurbishments of the property.
