Tenants will play on your emotions to serve themselves.  

Also we are planning on ripping the oil furnace out and putting in a high efficiency gas so I feel as though I should play hard ball and tell him to take his fuel which legally he can do before closing, if that is the case the PVC vents could go away however that's only worth 200.

I am also not sure what laws fall into play here.

If it's a long term play, like it sounds, keep it and keep making money.

Layout the framework of the operating agreement you envision and they should be able to pull it all together for you and help you create the legal entity to make this happen.Having said that - I would be interested to see how this all plays out.  

You can also pay them per sign and then give them like a 10% bonus of what you make from a deal each time a buyer you got from a sign call buys a house.

Double close is perfectly legal, but some banks have convinced the title companies to play by bank rules because the banks have so much influence and leverage.

To me, that is the difference between a "wholesaler" and a scam artist playing games with peoples lives and their home.

Is it strictly a cash flow play?

I worked two days and had two rooms looking,  well, the home sold and I received a bonus...I am working on my own flips to gain capital for rentals.
