The goal would be to gain a method to deposit MOs in a way that wouldn’t attract too much attention. It seems paying off debt (mortgage, car loan, etc) gets less critical attention. For example, I’ve paid close to $50k of mortgage payments with MO, and never had a question. I’ve also paid property taxes to the county for $18k over the last year, and they’ve never hassled me as long the payment is in full. In contrast, for some checking accounts I’ve gotten questions about as little as $2k in MO at a time.
A secondary goal would be to lower my bust out score, which is currently thought to be a risk for shutdown by a bank I’m currently enjoying. More than 1 real estate line open apparently lowers a person’s bust out risk score according to reddit.
