Hire a GC vs. Acting as own GC

[Ryan Reddy]

Hey Y'all, 

I'm looking to buy my first house flip in Denver, CO and I was wondering everyone's experience if it is better to hire a GC or act as my own when first starting out? 

The types of renovations I am looking at are primarily cosmetic an advanced cosmetic, the goal is to avoid any flips that require major mechanical / structural work.  

I see the pros and cons of both sides, while hiring a GC will help ease the entire process as well as have the construction expertise but I also see the GC fees eating in my profits as an investor.
I have read articles and books that say it can cost more by acting as own GC by making mistakes but also talked to RE investors in my market saying that acting as my own GC is the only way to make money. 

I have no construction experience and my current RE team has built their personal homes which could help provide some guidance but no one is a contractor.

I would love to hear about your experiences as well as if you have any nightmare stories from working with a GC / acting as your own and what you would recommend if you were starting out in my shoes with the knowledge you know today?
