Ok, so you might have a reason that you think will cause housing prices to go down in New York. Why do you also think that they will go up in somewhere else? Much of the real estate in much of the US just keeps up with inflation (or at least the land does - the buildings depreciate) unless there is some factor that is in demand - i.e. lakefront or oceanfront property. I wouldn't want to be buying some house in a big flat town in the praries and then be expecting to make money off the appreciation when it's just too easy to go another 300 feet and plunk down another new house. If you're buying it to live in the small town that's one thing or you expect to make money off the rental income but making money off the appreciation?
Right on the money with that observation.
Historically, the property in Las Vegas has been dirt cheap compared to Calif.
The population increased to well over l,000,000 from less than 200,000 over about a 10 year period.
Along with the influx, and the demands of the infrastructure, with that type of growth, they tightened up their areas of buildability. The property has doubled in value in last two years alone.
The high rollers in real estate understand this, and even though the original cost of admission may appear out of whack with what's going on in the middle part of the country, the fact is that as long as the demand exceeds the supply, (Bay Area of Calif. for instance), there may be periods of flatness, but the general trend will exceed most of the country. (Of course a major earthquake would have an unsettling effect)

As Hyperborea pointed out, if you are looking for appreciation, you'll have to pony up. If you are looking for a quality of life area, with minimum upside, as many are, nothing wrong with treating your house as a paid up security blanket.
