Some parts black near the toilet.

More toilet flushes, more feet on the flooring, more opening/closing cabinets, more turns of the faucet. 

(Also, technically need a plumber to pull a permit to replace a toilet, swap a faucet... and other silly things)If you did a new roof, they know you exceeded the cost.

Do you have to buy fixtures like light switches , faucets , toilets ..ect unless yu get a written bid there is no way to get exact figures only a best guess.

Please let us know how this pan out. 

I just closed on it and now I've painted, installed my first light fixture (way easier than I ever imagined), tiled the bathroom and put in a toilet!

If you are going to spend the money, you probably don't want to keep dealing with them.Let us all know how it pans out.

The whole house was repainted, laminate hardwood floors laid in the living areas, new baseboard trim, new carpet in the bedrooms, new tile flooring in the bathrooms and outside patio, granite countertops in kitchen and all bathrooms, stainless steel appliances, paint the cabinets, new toilets and plumbing fixtures, new lighting, and all tubs and surrounds were refinished.

Both times it was the toilet supply line that failed.

You could plug it into the BP calculator to start to see where numbers pan out.
