Finally, if the actual numbers are very different that what was represented in the listing, like others have said, this is a very powerful tool for renegotiating once the property is off the market (under contract).Good luck!

As Brian said, your CPA should be able to point you in the right direction.Keep in mind you want to be sure there is enough liquid cash in the account to cover property taxes, insurance payments, unexpected or needed repairs or improvements to the properties, utility bills and so forth.    

He should be hitting economy of scale by now, so his buying power is about to explode if he is doing things right.A handful of years ago, a guy in my area pulled some investor capital and bought a bunch of houses while paying them 8-10% interest only, BRRR till he paid them off and upgraded bank financing.

This same house has a 150 foot run of 10 gage wire to power the stove top.

I have the house, driveway, walkways, fences, decks and roof power washed to bring the materials to a common color - while my competition has gray fences - I bring mine back to a beautiful wood finish, my drives are one consistent color, etc.  

It would be pretty interesting if power play comes in and you still have the tenant legal system on your side.

Unless your lease gives you the power to ban guests based on behavior, I would say that you are more or less out of luck unless you can get a restraining order against him based on his behavior towards you.

@Michael Julian,I hate and expect a day or two vacancy but not having the ability of lining up the next tenant is unexpected and kind of infuriating considering all the things I've done to help her.
