But I am worried about a scenario where it drops by another 80-100K in the next 2 years and does not ever come back to current price levels in next 15 years.
Whatever may be the current ups & downs in Temecula market prices, in 15 years, the price will definitely double, at least. Beyond, 2011, $ has to sink fast and furiously. Real Estate will then become fashionable once again as a common man's hedge against inflation. You may even encounter another bubble and sell it to retire rich!
