Often the ex comes around and there are screaming fights, and they almost always move out within months to move back in with the ex. 

We know this works because everyone on the left screamed welfare reform in the 90's was going to create more homeless people but it actually resulted in more people getting jobs and becoming self-sufficient.The only thing I would offer poor people is opportunity.

And you scream at the top of your lungs that you will accept the S8 voucher!

If it was a screaming deal, I would find a carrier that would cover me in the short term, take possession, then immediately terminate the tenant's lease. 

That being said, two people per room (parent/child) is very reasonable.As far as the girlfriend, you should have rules in the lease about visitors to limit how many nights she is spending there.

If they sounded drunk, were screaming at their kids, had someone in the background telling them what to say - I'd make a notation and whether or not I called them back.You only have to worry about protected classes.  

I also have a clause (lifted right out of Bigger Pocket's The Book on Managing Rental Properties thank-you-very-much) about anyone staying longer than 14 days is someone who needs to apply and be added to the lease if they meet the requirements etc…My worry is that the company will pay the rent, have this one person on the lease and then will cycle 'visitors' through the property essentially as a short term hotel.  

Oh man, I had 2 acres about 1 1/2 hours outside of Portland, OR and I'd catch the city folk letting their pests loose on the far driveway to my property and I'd run screaming at them like a crazy banshee.If you're going to trap your problems, to move somewhere for someone else to deal with - at least take them all the way into the middle of a national forest.  

People who intend on living in your unit will want to know about laundry), or because they scream at their kids or bicker with each other, or waste your time by showing up late or not giving you requested documents when they said they would.....just on and on. 

That can be tedious but the only way.Also ensure that your doctor or heath facilities you visit or plan to visit takes that health particular plan, before you sign up.Unfortunately, no one in either parties elected or running for office been able to fix health care in the US.
