Well, in the old days this would have been easy enough since mixed use was all about one structure. You say they aren't connected as far as buildings....but are the structures considered to be on the same tract or no? Based on the information provided, it sounds reportable as a purchase......but if on the same tract, you'd need to employ the mixed use test to determine the "property's" primary use. Out of curiosity, are all of the buildings currently owned by the same person/entity?
I'm fixin' to fix that.
