I think Santa Luz will continue to tighten up due to many reasons. One of them will be tightening lending standards and a reduction in the jumbo limit. Additionally higher rates really put pressure on homes like those priced in Santa Luz. You have a nice area with high fees, also you have alot of speculators including realtors that bought there several years ago. They are all feeling pinched and I believe will continue to feel pain as we move forward in the next few years. If rates for really high you may see some very nice deals there. I still view it as high risk compared to other neighborhoods.
It is a very nice place though.
Earlyretirement I would advise you to drive out there and check it out. Alot of times even when you can see the power lines from google earth, you cannot get the perspective and the feel for them.
