What should be included in quote from contractors

[Jake Engle]

When I am compiling quotes from contractors for fix and flips, should I be including material (Kitchen cabinets, flooring, etc.)? I know from reading other topics on here, a lot of investors purchase the materials themselves with credit cards to get rewards and airline miles. Is the best way to go to just have contractors provide quote for install on them items? Thanks for any input you can provide.
