The half of the red that is empty and not sold to builders is just more of the same models that are in the bottom portion. So Standard Pacific, Shae, and Lang, and Donaldson. When that land was developed Black Mountain Ranch thought by now all the lots would have been sold. lol. The good news it looks as if BMR reduced the lot prices to builders. But, yeah it will still be another 4-5 years before even the existing land is filled. Then another 10 on top of that to fill the rest.
