Partnering up / Due Diligence

[Simcha Davidman]

I recently spoke with someone with whom I am considering partnering up, because I am looking to invest out of state, and this person lives in that area.  I met him here on BP about a week ago, we had a nice 45 minute conversation, and I am going to travel to his location within the next couple of weeks to meet him in person.  I also see this as an opportunity to build a long term relationship, in which I can raise capital and he can find/manage the properties.

However, how do I come to trust this person?  What should I look for, either good signs or red flags?  What does my due diligence look like before we formally join together?

(If you're reading this, potential partner, no hard feelings :) )

Thank you in advance!
