12000 sq ft building with fire damage- rehab estimate?

[Josh Caldwell]

Ok gang, I need some general numbers.  I am looking at a building that I can't get access to until after I buy it at the tax sale.  I know the building is a brick structure and it is listed as fire damaged.  The price to purchase is super cheap. So I am looking for worst case scenario estimates on damage to a 12,000 2 story building sq ft building.  Any numbers will be appreciated.  

Thank you 

Josh

What's the land worth and the highest and best use? The answer might be too tear down the existing structure and the cost to do so versus existing use and structure with a restoration.
