How much are the mortgage repayments on a 600,000 pounds house?

As the Madeleine fund is paying the McCanns mortgage and living expenses I am interested in finding out how much of the money that was donated by good people to HUNT for Madeleine and leave no stone unturned is being diverted from this to pay the mortgage on the McCanns 600,000 pounds house and I wonder how long this situation will remain.
