Your first point I agree with. Obviously Garden Oaks is not going to incorporate and start its own city services. I certainly wasn't going to suggest that. West University will always have that going for it.
I have to take some exception to your other comments though. It's a transitional area, so of course it's going to be surrounded by "iffy" areas. If this weren't the case, the lots would already be going for higher. As property values rise in that area, you will see gentrification take its course.
As far as your comments about Doctors living in the area, there probably won't be as many, but there are plenty of other professions in the city that can support expensive property expansion.
Garden Oaks also has larger lot sizes for the most part than Braes Heights, but if new homes in Garden Oaks eventually start averaging ~900K, that still wont' be a bad thing for residents
