When I was new, my worst tenants came thru realtors or property managers, like the 9-person family who only put two adults and two kids on the application, but the PM only provided me the written application to review because the applicant belonged to a protected class and the PM was afraid of getting sued.For only owning/managing one rental, I wouldn't hire a PM.

About 8 people lived in the house from three generations: the parents who were divorcing, adult children, and the spouse and children of one of the adult children. 

That's weird.Sometimes it's because they are still financially supporting their 35+ year old "adult" children ...

I found out the state of Vermont defines a boarding house as more than five unrelated adults renting rooms in a dwelling unit.

In light of this release, I thought we could share the bit of advice we wish we had as a teen or young adult.

But, in the adult world there are consequences for not following through on your contract obligations.Calling it going gangsta is a way to put humor into an expensive, bad experience, and taking the mindset that I'm not going to be a victim.  

You know, a house is a coutable asset, and Medicaid would require that it be used when a spouse or an adult child is no longer living there.  

That's a higher risk for a parent/adult than pretty much any normal rental.

I'd let them know you'll not be renewing their lease, you are going to a limited pet / animal policy, 1 per unit, adult weight limit of 20 lbs. .. or better yet no pet policy.Until then they must provide proof of insurance that cover them for their dog and I'd check again with your agent and see what their thoughts are,, I bet your agent says, to get a remove this animal as soon as possible and then you'd have to give them a mutual lease termination to show compliance for your insurance company until they are gone. 

I've been in real estate related businesses all of my adult career.
