I've noticed some very low prices at Big Bear. The sort of prices that make you say "Wow, that's cheap."
It surprised me because that is a very nice recreational area close to the LA basin. It would seem to me that Big Bear should be hot right now, as people rein in their vacation plans and stay much closer to home.
But people worried about the economy are not buying toys. So it is possible that there are no buyers and plenty of vacation renters. That would make a nice investment opportunity.
That's not a suggestion to buy. Do your homework. I don't know the area well enough that I'd buy myself without a lot of study.
OK, a bit of advice: be very certain you are getting a good septic or sewer system. Lots up there are too small to adequately support a septic, so sewage might be an issue.
