I am getting a mortgage and have been provisionally approved I have to pay 20000 of a deposit but dont have it all but will by the time the house is completed by december (i know that it will probably be after december) is it possible to get a loan now to pay the deposit now without it affecting my ability to get a mortgage. I have a lump sum due later in the year which I could pay off the loan with. or would the timing affect my ability to get a mortgage?
