Hi I have a dispute with Capital Home Loans over suitable security and portability of my loan because the 10 year fixed loan I had was in its tenth year and I wanted to sell the house on which the banks charge was registered. The early penalty was 5% - the early repayment penalty mounted to circa 9K. I wrote to CHL and explained that I was selling the house ( a buy to let property) but did not want to repay my mortgage until the 10years was up and requested that they port their charge to a new security. I offered CHL an HSBC bank guarantee for the total sum of the mortgage plus the remaining 9 months interest but they said that although my mortgage was portable a bank guarantee was not acceptable collateral and insisted the early penalty had to be paid. I can find no specific definition of acceptable security in my contract and am insisting that the bank guarantee offered was as good if not better than any other form of security. What do you think my chances of wining a case for the recovery of my 9K are?
