This place is old family land that was sold out and I purchased back into the family.

I am developing some land into a retail commercial building of $19,000SF.

Your depreciation guess seems low unless the land was very valuable compared to the building. 

We have acquired properties in 2 counties for the sole purpose of developing un disturbed lands and retrofitting existing farm then leasing to cultivators.

I remember plenty of railroad track embankments that were up for sale (railroads were exempt from abandonment/sales by law, but the slopes of the land on either side weren't and they always popped up - of course completely useless as an example). 

Did Canton GA (or Cherokee county) land a new auto manufacturing deal lately?

If the stone itself is in decent shape I would get one of these really powerful powerwashers they now have and clean it.

I assume the basis for depreciation does not include land. 

The "dealer" provisions have nothing to do with flipping and are specifically intended for use by land developers..... 

Buying before land was listed.
