Rehab 6000 square feet house

[Kishore K.]

Hi,

What would it cost to rehab a 6000 sq feet house with Viking sub zero appliances, hard wood floor in all areas , finished basement, tray ceilings, iPad controlled audio, tv, electrical system, new roof , ultra luxury bathroom (s)with Carrera marble, extremely energy efficient windows and walls, cat 6 cable wiring everywhere.

House is 6 BED6 BR with all brick and stone on outside with everything else gutted inside .Lot size is more than half acre.

Please ask any questions if I have left any details.

PS Similar houses in that subdivision which are > 25 years old sell for 1.7-2 million.

PPS I was planning to build new house on a vacant smaller lot, but since new property came up have decided to explore it.

Thanks.
