For me, I would never put a male roommate with 3 female roommates, where the 3 female roommates did not give their approval and do not know the guy.  

Haha ;) In our larger properties, 2+ bedrooms, the long-term tenant is sometimes comfortable with staying in a shared AirBnB bedroom (shared female or male only rooms).

She will never stay in law school, and so she'll lose her funding.And once the BF/fiance moves in, he's a tenant who also has to be kicked out.I had a female law student whose "fiance" moved in, and he just sat round in the apartment playing videos all day long.  

My tenants are both female, and they are friends.  

The mom's credit score is almost 700, and she talks very sincerely and looks eager to move in.3.A group of 4 college senior female students and a co-signer who is the father of one tenant. 

When I asked about her (we thought she was over 18), because male tenant said "we are thinking of having her stay with us for the summer" (violation of lease which says visitors can stay 7 days), the female tenant replied "he misled you, sister visits for help with homework, she spends the night sometimes".  

We were informed by the male tenant last week that the female had moved out.

I have a tenant (single female) on the 1st floor who has only been there a few weeks and has sex quite loudly around 2am when I am trying to sleep after putting in a 12-16hr workday.

And are you renting to females or males or co-ed?

I'm 23 year old female, I attended University of VermontBurlington, VT and graduated last year.
