Many tax laws are open to interpretation and even an incorrect application abuse of the law is probably not getting anyone thrown in jail especially when they will eventually pay their taxes on the money. 

After the eviction, you normally are left with some of their possessions (which is super frustrating). at that point, you would need to store them for a bit (ask your attorney) and then you can toss them if the tenant doesn't pick them up.

How do you store it?

He sent me an address to a vacant lot and to a ups store as his home address.

Is your DSCR ratio greater than 1-meaning are you cash flowing (according to the lender's criteria of mortgage, property taxes and insurance (and HOA) if applicable).

If they provide sketchy information, deny their application and move on.

Better to lose a non-refundable application fee than your shirt.
