There are a number of ways to find homes: Wholesalers, MLS, driving for dollars, mailing campaigns, Auctions, Bird Dogs,  etc.  

They are on a month to month lease which we have informed them we will not be renewing for a couple reasons, the first being that they are a complete slob and are trashing the place / from the looks of it are the reason the place had bedbugs with the previous owner , the second being that they have dogs that are not covered under my insurance. 

As for the PM issue as long as you screen really well and pay attention to basic maintenance 10-20 will be easier than your current 3x3 buildings provided you do not pick a dog for the 10-20!

Generally, you cannot prohibit service animals, but in this case, it doesn't sound like the dog is actively working.

Personally, I started out looking for deals for other investors by bird-dogging and wholesaling.

Also this would tell if someone or something like a big dog is staying but not on the lease.

Her dogs pissed everywhere, we’re out about $6k.This was an experience with VRBOHomeaway.

I'll be napping in the meamtime.But the last 3 dogs I sold easily by owner for full retail should have given me a clue :)  At least you didn't buy bitcoin at $19k.

Does anyone know if Emotional Support Dogs, with all their paperwork (whatever that means) are a protected class? 

Maybe that is bird-dogging deals once you learn how to evaluate deals, maybe it is cleaning up their flips/rentals, etc.
