What would a gutted rehab cost?

[Herbert MacDonald]

Im trying to figure out the cost of rehabbing a gutted house on a property I found that is being sold as "lot for sale." I called and they are asking market value of a house, $210k. The house on the property is completly gutted since the current owners wanted to demolish it and build new on the property which is 7,200 SF. As it stands, the house is a 1960's 3/2 - 1525 Sq' completely gutted, has no AC, no central heat, not flooring and original windows... just exterior walls, roof, and bare studs. No foundation issues). 

A ball park figure would greatly help in my calculations, and any advise would be greatly appreciated.
