Shadow - This is what I do for a living. First of all let me tell you that all of these numbers are estimates and based on the type of finish you are looking for these numbers can vary substantially.
Flooring throughout (cheaper wood laminate or carpet is ok)
- Painting throughout (interior for sure and possibly exterior)
- Kitchen complete remodel (new appliances, new cabinets, and tear down a wall with old cabinets)
- renovations on 2 bathrooms....(maybe not complete but for the sake of caution, lets say complete)
- No structural changes.....but possibly adding a few walls to enlcose open rooms.
- change out some windows and doors.
Flooring - 2,100 Sq foot - you can buy a decent laminate for $1 sq foot but let's figure about $1.50. Better safe then sorry. Figure about $3,500, then add in underlayment, labor, transition strips, pad if you do carpet(would be fairly cheap long term, but look good short term)
$4,000
Painting - Figure paint, brushes, tape, rollers, etc
$500
Kitchen Remodel - This is the toughest estimate. Assume you use in stock cabinets from Home Depot(Really nice cabinets for the price, put them in one of my houses- Dark Cherry Wood, with Crown) You are looking at about $6,000. Now I had ALOT of cabinet space. If you go with a formica laminate which looks real nice you are looking at maybe $250 or so. I did that with a crown molding to make it look nicer. Sink $200, faucet $100, garbage $150, New Dishwasher - $350, New Microwave $125. Now you can get a decent used fridge for $500, Used Stove $250.
Knock out walls, new drywall, framing, finishing, $150
So kitchen looking pretty nice $8,500
Bathroom Remodel X 2 - Assuming tubs are in good shape - if not add $1000 for two new tubs. Ok so new vanity -$150, Faucet $100, Tiling - $150 (I like to tile the showers, cheap but looks REALLY NICE) Tile Floor $125, Trim out -(Towel hangers, robe hooks, ETC) - $125. I am assuming a small bath. Now a new top and cabinets can add some money here.
So making a bathroom look pretty nice I would figure $750 X 2
$1500 -(Excluding new tubs)
Adding/taking some new walls figure $250
Adding new windows(Some) and some new doors figure $1000. Add $250-$500 for new trim throughout.
Light fixtures, new trim out of old outlets(If they look bad), Ceiling fans, faceplates, $750
Again this is a real standard estimate not including labor charges because I do everything myself so you would have to factor that in. I would guess since you are asking you probably aren't doing these things by yourself. . . So in MATERIALS alone your looking at $15,500.
I have no clue on your exterior, siding, landscaping, concrete work, do you want to add a deck, roofing, painting?
Furnace good, water heater, air conditioner, insulation, drainage - How is all of that?
This is vague, but I always add $5000 or so to have a decent estimate. . however again if you aren't doing all of this work yourself I would guess $30,000.
I hope this helps. Feel free to PM me if you need anything answered.
