Foreclosed multi story shell building is worth ...?

[Alfred Harding]

What would be a good price for 5 story building at the shell level? The building has exterior walls and windows, fire suppression, HVAC, elevator, roof, plumbing and electrical connections on each floor. If the building was 50,000 sq. ft. and I was to purchase say one floor of 10,000 sq. ft. What would be a realistic price in a small market like Santa Fe with 65,000 residents. Commercial vs. Residential? No parking available for residential, walking distance for commercial.
