Gilbert,
I have been thinking about you and wondering how you are doing with your home search. Your Doctor may be advising you to be at even a lower elevation [My understanding is that Mile-High elevations like Prescott are considered just at the margin for altitude related health issues]. I know that when my Mom moved to Prescott from Flagstaff at 7,000 +/- in elevation, there was a vast improvement to her health.
The Verde Valley may be a good option for you. I can help you find a wonderful agent there. If you are interested, e-mail me at ann@myprescottplace.com. Properties with more than one home on a single lot are available there. The Elevation in the Verde/Cottonwood/Sedona area is just at 3,000 ft +/-. - Sat Dec 12 2009, 21:11
