Who can I talk to to figure out why my status was reduced from Pro?

Figure out who your "customer" would be and set everything up to target them.

She is willing to sign on as the main tenant which means she is responsible for the apartment. my thoughts thinking out loud:the other prospective tenants have income issues so at least in this case I know the rent will be paid. the mother has pretty significant assets (low 6 figures + another 6 figures from sale of the house) if he destroys the property I could go after her for it right?

A lot of good opinions on here already but I figured I would share mine.I don't personally have any short term rentals in NH or Florida but do have one just over the border in Southern Maine.
