Wrap Mortgage Seller does not pay

[Account Closed]

I worry and no idea what to do when said, in the near future the seller decided to use the payment i give to him from my buyer in a wrap mortgage translation for his personal gain instead of paying the bank. I know if my buyer default the property will be foreclosure and return back to me, and the same if i myself default and the property return back to the seller. But what if the seller decided he will no longer pay to the bank for his mortgage, what do i do?

@Account Closed's answer still applies.  Use a servicer who accepts the payment from the end buyers, pays the underlying mortgage and distributes the remaining funds as you specify.
