is this relating to a loan that you have had or does it predate you? I certainly wouldn't be offering to pay them anything unless you know you owe them money. As I suggested earlier, go back to the and ask for PROOF that they are entitled to have a charge on your property and if they can't supply proof, then require them to remove it. You might also ask whether they have records of any charges on houses with a similar address as its not unheard of for mistakes to happen and the charge to be put against the wrong house.
