Charles Morley, director of mortgage distribution at Metro Bank, said: “We’re pleased to reintroduce these higher LTV rates on our five-year fixed rate mortgages.
“As physical valuations have returned – and our market gradually begins to reopen – we wanted to give greater choice to customers who can afford to borrow more, as well as those that are keen to step onto the housing ladder for the first time.”
