Tell tenants to call police anytime there is domestic disturbances or she is damaging property.

You'll cry yourself to sleep at night if you try it with 50.

Now, in less than a year, there are 5 kids (the 5th baby arrived just few weeks ago) and 3 dogs, doing "dodos" everywhere, attacking us on our own property, tenants don't seem to work and it's hard to imagine how they make living (neither one of them seem to work), causing noise disturbance by loud inappropriate music every time we are in our back yard, etc... 

I imagine the worst: a neighbor who is trashy and keeps empty soda cans or water bottles on the lawn, toys strewn about, doesn't cut the grass, smokes, has excessive traffic, vicious dogs, unclean or untidy enough to attract and feed roaches, loud music that disturbs my tenant, or even maintenance like the roof or windows.

If you do not stay on top of it, even with a PM, you risk losing a lot of money and sleep.    

She added a page called house rules where I could be evicted if my bf's dog sleeps over.

The only thing guaranteed is the big sleep at the end of the road.

If it's not intended as sleeping quarters, I'd want to ask the question.Another question is about the plumbing: From a basement perspective, are the drains "overhead"?

Please just so i can sleep tonight Lin promise me you'll sell that terrible investment and put the funds into Vanguard total market index fund. 4X return 0 work. 

This has allowed us to sleep way more ppl and has gotten us some awesome reviews and increased our bookings.
