This may sound like a stupid question for all you experts out there but for me, I have to ask. :b I am just about on the drywall stage and need to know whether I need to install my prehung doors (those kits sold at home depot with door and frame) before the drywall goes up. Can they be installed after the drywall is finished? I ask because, well my cash flow really isn't flowing that much any more and I'd have to wait to purchase drywall if I purchase the doors. If I get drywall first, then the room can be at least operational. And i'll have much more to do (mudding,sanding,etc.) with drywall and give me time to save more money. The places where doors will need to be installed will have unfinished space on the other side i.e. I will be able to see the framing/insullation.
