How much will it costs to fix a house? (average)? if we are talking roughly speaking a house with 4 bed....

if we are talking roughly speaking a house with 4 bed. more than 2000 sqft, need a new kitchen, laundry room , possibly a clean roof.
how much will it costs to fix all this things??
Ey! if you can endow with me a link where on earth i can read about fixing up a house and how much would it cost, would be nice.
Thanks!
Answers:    It depends on what the local labor souk is charging in your nouns. To get a guess on the cost, break the errand down into sections, labor for the roof, materials, labor for the kitchen and materials, same for the laundry. Ask several contractors for bids and start from within. I would suspect that it will run twice what you hoped, maybe $60K.
Prob count on $40-55 a SF. Building tentative is rated at $75 to $100 per SF.
