How to vet turnkey companies other than reviews

[Tanner Shore]

Hey BP fam, 

I am a brand new investor and have decided OOS turnkeys is the route I am going to take. It might be because I am new and don't want to get burned, but I have heard stories of some turnkey companies being shady and having only their best interest in mind. 

My question is, what negative experiences or mistakes have you ever had/heard of from turnkey companies? I plan to go the turnkey route for my first 3-5 properties and maybe even all, so I want to make sure I choose a company that I can "partner" with for years and deals to come. 

Question #2, other than good reviews and referrals, are there are other good ways to vet these companies? Any and all input is appreciated! Thank you.
