If I see a lot of pictures of wild, drunken-looking behavior in groups, they lose points.After having so many 20-somethings, I do find myself craving some 50-somethings.

In America, small business is being increasingly looked upon as a criminal behavior by both the public and governments and our society is extremely litigious. 

This is not a situation for aggressive behavior -- setting foot into this apartment while this particular tenant is still living there would be considered an "aggressive" move, given the info you have given us and it does not matter what the the law says at this point.

I train students all over the country and its just helpful for you to be licensed.Ohio, Florida, and California, it’s really important to hold a Real Estate Sales license doing seller financing.The Department of real estate estate is aggressive there in those states.Finding a real estate broker that you can work with isn’t easy, because they like to be able to control your work behavior, but there’s many places that will allow you to hold your shingle, meaning your license, and you have the regulations covered.2.

Based on the behavior you've described I don't think I'd want her in my rental anyway and would offer her a deal to return the keys and leave, but I wouldn't do this without there being a consequence to her (deposit forfeited, rent paid for the time she's had possession and possibly lease break fee).  

Newbies have no clue as to what is ethical, they don't understand the industry and therefore have no clue as to what acceptable behavior might be.
