re: Cost to renovate a gutted house?

If it's down to the studs, what the difference?

I think it can be done much cheaper with decent finishes personally.

You could do an engineered wood floor throughout for less than $7/SF installed

Painting should be less, way less than $10k

HVAC should be less than 7k

Electrical and pluming together should be less than 15k

Everything else seems to be a good rough estimate minus cabinets and countertops, I'd put that closer to 20k.
