Lawyer or RE Agent for turnkey investments?

[Jeremy Schreiber]

Hi BP Gurus,

It appears that when investing with a respected turnkey company, they attempt to sell directly to you.  Their sales people are effectively serving as the real-estate agent, which creates some mis-aligned incentives.    Should I bring my own real-estate agent to help navigate the contracts?  Would the turnkey company pay their 3% commission if I did?   

Should I instead bring a laywer to the table?  

Does anyone have advice on how best to proceed, and what professional advice is necessary before signing?

Thanks
