several years and I still have some of the forecast models I put together. I can say with near certainty that housing will begin to recover (IE prices consistantly rising) no earlier than 3-4 years. Housing will again hit bubble-peak prices in about 8-10 years.
Short answer, if you bought your house during peak years, you're in a mess and the best answer is actually to foreclose/shortsale/bankruptcy unless you have endless money in your bank and don't care about the money you'll keep losing for years and years.
Any analyst will tell you the same thing. Don't ask a broker or someone with a financial incentive to lie, because they don't know squat about housing economics.
