We had an older lady tenant complain that the NEW girl who moved in was 'entertaining' & taking up visitor parking.

I am a real estate agent + I'm in the middle of a gut rehab and it's hard to balance all of this with family ( kids + partner) my wife was a single mom with 3 girls and her sole income was selling real estate prior to us meeting. 

I'm a married, mom of 3 girls 9 and under. 

Last night, one tenant complained that two tenants were running around the house being loud and wrestling (a girl and a guy who barely know each other) and that caused the dogs in a bedroom from another tenant to bark non stop.

I don’t have any experience doing this personally, but I’m on Long Island and this is exactly what the couple who owns the property that my girl lives in does.They bought a home, lived in the home while they renovated it, added a basement unit and rented it out.

Do a Google search for "Boommates" and you'll find references to the Golden Girls TV show and discussions about two significant issues older people face: the high cost of housing and loneliness.For younger people, we call this "house hacking," where someone buys a house and takes in roommates to help cover the costs.

48 hours after this boyfriend and girlfriend move in I get a message from the guy that the girl punched him in his eye and he is scared to live there and wants off the lease.   

There were a lot of young hustlers.  2 local girls worked supporting the summit to go.  

Father of 2 girls.

Answer: that's up to you.BTW, like others have said, you girl should not have any say in the investment, unless she will be putting in capital.
