Options for Partnership structure?

[Phil Morgan]

I have a few duplexes and am looking to go bigger.  I also have an investor who is more than willing to be the private money behind growing my portfolio.  My question is about how to structure our partnership.  If he wants to be a 100% passive investor vs if he wants to be involved in the day to day processes.  He has the funds to buy virtually anything I am looking at and has already told me that he is willing to front 100% of the funds upfront to get a deal done (with the plans to refi down the road after value has been added).  I have never worked with a partner and own all my duplexes myself so this is a whole new ballgame for me.  Any advice you can give or directions you can point me in would be much appreciated.

Thanks
