Bridging loans can be from £50,000 to £5 million. A 25% deposit is typically required but normally this would come from the equity in the property being sold, so no cash deposit is necessary. Example: Bridging Loan House being purchased: £450,000 House being sold: £750,000 with a £150,000 mortgage outstanding The bank will take a charge over both properties as security for a £450,000 Bridging loan to purchase the property. When the house is sold, it repays the existing mortgage and also the bridging loan; the surplus funds are sent to the owner.
