General cost for this renovation

[Dominick Marschall]

Hi everyone, I'm about to buy a 2 bed 1 bath house. Its in good condition, but older and i'm looking to do a top to bottom remodel on the inside. Bathroom remodel, kitchen remodel, new flooring, windows, furnace, a/c, lighting, doors, paint, etc, basically to studs. What do you think a general price range would be? I'm going to get multiple bids, but i'm just curious. Do you typically do it per sq ft? Any advice would be great! Thanks!
