Let you guys kick these cams down the road!

You would need to look very heavily at that business.You need to check the leases as they generally CAP the CAM expenses a tenant will pay by a certain percent.Is Subway and Metro PCS corp or franchisee??

Another tenant did this and the couple were "sex workers" where she was the main one working and he was her security. 

My roommate agreement specified things like: furnished or unfurnished, maximum occupancy- limiting number of overnight guests as it's bills paid roommate living, if it's co-ed or single sex, no smoking vaping e-cigs or substances on the property, cleaning chores/expectations, no underage drinking, pet rules, what utilities are included up to what limits and what utilities aren't included, etc.Require a security deposit from each roommate, even if small.Get a locking thermostat cover; set utility allowances so people won't take advantage of "all bills paid" rooms and have the daughter/master tenant or whoever is paying the utility bills be the person who sets the utilities.

Treat disabilities like you treat race, sexual orientation, sex, age, nationality, religion etc.

Why make your tenants have background checks if you're going to let them move in their boyfriends/girlfriends/friends who are violent offenders or sex offenders?

Her son who is the sex offender has a job for 1 year.

I think a cam would be obnoxious, but an interesting idea has occured to me.

In my state, that would include things like court records, criminal convictions, sex offender registration, etc.
