As Ethel has said, maybe only specialist lenders will deal with you at the moment ~ so yes, you can get a mortgage however you may need a larger deposit and have to borrow at a higher interest rate.
We went for one of those deals after Mr Pippa was discharged ~ mainly because we wanted to buy a house there and then as we feared we may miss the boat...as house prces were rising dramatically. We are glad we did, and could just about afford the deal we were offered.
Four years later we were in a better position to switch to a High St lender.
