I am second viewing a 2 year old timer framed eco house with Knauf aquapanels. The EA has suggested that Nationwide may not lend on such a property and I was hoping to port my current mortgage over. There is 8 years left on the building certificate. Does anyone have any experience of mortgage providers who would lend on such a property? I intend to call the Nationwide when I back from holiday but thought I would ask on here too. Thank you.
