Cheldon Financial Services is bound by the original terms and condition of your loan agreement, that is all. From anecdotal evidence to date, third party purchasers of loans usually go along with the any special arrangements in place between the original mortgagee and the mortgagor that were in place at the time they purchased the loan book. However, having said that, if it is not financially beneficial to the new party to the agreement, they are well within their rights to enforce the agreement if the borrower has broken the original terms and conditions of the loan.
In relation to your question, the simple answer is yes they are, again having said that, if you are up to date on one loan and not the other and the loans are cross secured against each other, or there is an all sums clause within the loan contracts, Cheldon Financial Services could seek enforcement of their securities on both loans as one loan is in default.
