If you have a current residential mortgage and you are planning on using the equity in this property to repay the bridging loans when the property is sold, then the Bridging lenders will take an additional/second charge behind your current mortgage lender. This is a practice mortgage lenders are familiar with and allow; we have not incurred any issues with it.  The lender will take a first legal charge on the property you are buying and a second charge on the property you are selling, which has the current mortgage secured on the property. When the property is sold, the loan is repaid fully or partially repaid from the proceeds of the sale.
