and plug in the mission park address...
3401 Cherry Ridge
You'll see the appraised square footage for the building.
Although, Julies brother isn't your average MDS user, so keep in mind that he's not retarded and when he says the place isn't that big....you can assume that that's a pretty accurate statement.
Given the number of floors and actual usable foot space, I really don't think the place is that big at all.....not to mention that it took them seconds to come out of the building to thwart me when I started nosing around.
