Which relationship(s) are most important to REI success?

[Rich S.]

Good day all BP'ers.  In having a discussion with a seasoned RE Investor this past week and picking his brain on the structure of his business I really deduced his success down to three main relationships:

#1- He has a realtor/partner(he has skin in the game) who handles buying and selling, along with finding deals.

#2- He has a "money guy" who provides him a line of credit.  Interesting structure to this one, with a pretty low interest rate, but "money guy" also gets a small % of each profit of every deal, but only if there is profit, so if a deal goes south, only interest.

#3- Has an attorney/inside man(my words, not his) that is ultra connected to distressed deals and seems to get them to the table on these deals before most others even know about them.

My question to the seasoned real estate investors out there, which relationship do YOU HAVE in your business that is most important?
