Investor structure/repayment

[Brian Palmer]

I am a looking for  advice/ books to help guide me the process of setting the proper entity when working with investors. How are they paid back, based on how much they invest. How much should I invest since I am doing all the work, they will just be passive.

 I currently have two duplex properties and one town home. I manage and do all repairs/remodeling. The potential investors are friends, I have saved for another duplex on my own but am looking at possibly using investor money for larger down payment for maybe a more profitable four or six unit property. One reason I would like to do this with investors is show I have a track record to possibly attract larger investors down the road as I try to build my business. Any input would be appreciated.
