With the plan allowing this terminated person to make loan payments with personal checks for 4 years, I wouldn't want to be the one to over-rule that decision. Changes to the loan program would apply to later loans, but they don't change the terms of an existing loan. How long until the loan is scheduled to be paid off?
Now, if this person sent a check that bounced, I think the plan would have an obligation to insist on a form of payment that won't bounce.
It is a 30 year home loan and all payments have been made timely. I really don't want to override what has happened nor do I really want to default the loan. I would just like to find some documentation so that if i have to prove why this was allowed, I can do it. At the same time I don't want to perpetuate an error, if it was an error.
