First partner question.

[Andrew Briones]

 A younger fellow employee at work has come up to me and ask about how I could help him get started into real estate investing since i bought my first investment property.  I thought we could purchase a duplex or 4 plex together and he live in it and rent out the other doors but im not sure how to make this offer to him and be fair for both of us. He has good credit but no money as I have both the credit and finances needed to put down and repairs if needed.  With him living there, it would be owner occupied. Im not sure what happens when it come down to the tittle and mortgage. We did mention a 7 year cap on the property. Could somebody send me some good options or point me in the  right direction?
