Who actually makes the monthly payment on a subject to deal
The operations side of a subject to deal deserves scrutiny before a team touches one. A common description is getting the seller's online login and making the payment from the buyer's account each month. That arrangement carries real risk. If the seller changes the password, or the lender flags an unfamiliar login, the buyer can be locked out of a loan they're responsible for and not find out until the payment is already late. Third party sub2 servicing companies exist specifically to solve this. They typically handle the payment processing directly with the lender, maintain a paper trail separate from a shared login, and monitor the loan for payment changes, insurance lapses, or notices from the lender, for a monthly fee that is usually modest relative to the risk of losing access to a password dependent process. Paying that fee is generally worth it compared to building an operation around a shared password.
