Cost to renovate a gutted house?

Slightly less than building a new one.

The cost of a house is in the finish. Not the frame which is basically all you currently have.

Depends on price range of comps.

Do floors need to be removed?

If not and it's around a 200k house, I'd guess budgeting around $6-7 / ft for flooring (Includes porcelain, grout for baths and engineered wood and glue for remaining).

Entire interior paint job will prob run you around 5k depending on trim, cabinets, etc.

Sheetrock depends on how much you need to replace. That's tough to give an estimate on.

Bedroom fans = $100
Living, Kitchen light fixtures = $300/piece.

I'm not sure how much reno you need on the kitchen, but a sink will run you a couple hundred bucks, a faucet will run a couple hundred, stone countertops will prob run around $80-$100 ft2.

You can get a stainless appliance package for a few grand (Not including fridge)
Add $1500-$1800 for fridge.

Bathroom faucets are around $60-$80 a piece.

Unless you're a plumber, I suggest hiring one to install faucets. I find it be a huge pain in the rear.

I'm sure I'm leaving some stuff out.

*this is assuming you have showers, tubs, etc.

I just did something very similar.

My guess would be between 35-40k.

When I renovated my house (similar size) we did all the work and spent about $40k in material. We touched everything (Plb, ele, floors, ceiling, all new bathrooms, floors). Double that for labor if you're not diy. Then add probably $10k-$20k for new drywall.

You're looking at $100k easily. Probably closer to $150k.

I am going to make a few assumptions & just throw out a few figures.

1. This going to be your home for the rest of your life.

2. The house is over 20 years old.

3. The house needs major work.

Total rewire of the house $8-10K, which I would do if this is going to be your home from here on out. Get an electrican to do this. Electricity is something you can't afford to make a mistake on.

Plumbing, do this right with good materials and a good plumber. You will come out miles ahead in the long run. Plumbers are expensive and good bathroom fixtures are expensive. Assuming you will have a full bath and a half bath, $10-15K.

Flooring. Go with tile or a good quality linolum. I made the mistake of going with carpet. I like the way it feels on my toes but man, its a headache to keep clean.
$10K minimum with linolum, probably double that with tile.

Roof. Get a metal roof. You most likely will never have to worry about replacing it in your lifetime. At least $10-12K

Kitchen. Go with good solid oak cabinets. Think @ least $10K. Or you could buy the cheaper stuff and save a few thousand.
You can spend on ton a granite counter tops but I would go with a good formica based counter top(s) $500-700.
Appliances: stove $800-1000, a good vent-a-hood for the kitchen $500, refrigerator $800-1000, dishwasher $500-800.

Sheet rock. Materials about $3-4K for entire house. Its an art to float in the sheet rock and make it look smooth. I just 'textured' our walls with sheetrock mud, a roller, and some cheap paint. Actually looks pretty good.

Paint, around 12-14 gallons should get it done.
Go with the good paint. $500

Then you are going to have to think about furniture...


Goodluck

I would plan on worst case scenario of $140/ft
