Interviewing,screening, and managing GCs

[Ki Lee]

Hello BP, 

New flip investor here.  I've heard from a lot of other investors that some of the hardest parts of flipping is finding and working with good GCs.  I've heard that they are few and far in between and that they can influence the outcome of a deal in a big way.  Can some of you more seasoned flipper impart some wisdom on screening and researching GC's?  How do I get them to take me seriously when I'm just starting out and don't have a property under contract yet?  What are some good questions to ask on the initial chat?  Should I wait until I have a property under contract to reach out to GC's?  Some of the biggest mistakes to watch out for when screening/dealing with GC's?
