I am just getting started with my first rehab project and I had been dealing with the same exact question you are dealing with. I bought a property at a great price and decided it was worth the extra cost to use a GC, mainly so that I can hopefully shadow him and learn from him, similar to what J has said.
I called and got three GC's to give me bids.
The first one said he was going to email me last Thursday with a bid - haven't heard from him yet, so he is out of the question.
The second one I met at the job site and he essentially said he wasn't interested in the job. He was however helpful and walked around with me giving me pointers and gave me some rec's for subs to use.
The third GC was interested in the job and gave me a reasonable estimate which I was ready to take, however I later learned that he let his insurance lapse so he was essentially an uninsured licensed GC - NOT what I am looking for.
In between these bids I was also getting bids from subs to do the specific work so that I had something to compare the GC's against. I ended up deciding that it will be best if I handle the hiring of the subs since there is no structural work being done.
I am getting electrical, plumbing, HVAC, Pool, and general work done on my property. The best way to tackle this I believe is starting with the systems first and then working your way down to the cosmetic issues. If you think about it, it's common sense. You need to fix the stuff behind the walls first before you start painting and paint before you install the light fixtures and.. etc..
If you are looking for something that needs cosmetic work, I think you should be OK. Between BP, my REIA group and my father I have been able to confidently start scheduling and planning out how I will get this house rehabbed.
I am embarrassingly very NOT handy, my father who is in NJ (I'm in FL now) and is handy has told me to not even think about doing any work myself.. :lol:
ONE of the keys is to network with the investors around you and get recommendations for subs. I have also reached out to J Scott more than a couple times, maybe borderline annoying, but his blog is a great resource and he is also very helpful himself if you reach out to him. I'd read his posts about hiring, finding and dealing with contractors along with what contracts he uses.
Take him up on his offer for lunch! Maybe he'll even share some of his subs with you.. :lol:
