Nevada is growing due to influz of out-of-staters; the same with Arizona, North Carolina, and Florida.
Yeah, we moved to Arizona from California last year and have not regretted it. The summer weather takes some getting used to, but otherwise Phoenix reminds me a lot of California about 30 years ago. The Phoenix metro area is growing rapidly. Housing prices are up about 40% in the last 18 months, but are still far below San Diego county where I used to live. We're looking for a little dip in housing prices to buy next year but I'm not waiting for a big decline. Ten percent is about the maximum decline that I'm expecting, and houses still seem really cheap to me after living in San Diego county.
