Details from General Contractor

[Justin Craver]

Hi All,

I am working through the process to close and begin work on my first investment property (flip) and have what I know are some basic questions.  

Background:  The house needs a good deal of work (roof, gutters, paint, floors, kitchen and bathroom updates, etc).  I have met with several GCs, and individual repairmen (painters, roofers,etc.) as I am trying to determine best route (piece it all together or have GC handle it all).  They have been to the house and seen the scope of work and have a good idea of expected repairs, in general terms.  I have gotten a few quotes back but none that I have back have a great amount of detail in terms of specific materials used (what rating floors, cabinets, vanities, etc.)  

I am obviously going to want to determine the look/quality of the purchases, so what is the best way to handle this?  Should I get the quotes to include allowable price range to stay within the quote on each of the items that will require my choice?  Should I request that the quote be essentially for the labor only and me purchase materials, etc. myself or directly through them as needed?

Thank you for your feedback as your input is greatly appreciated.
