According to a Yahoo article, LV leads the nation in the percentage of homeowners with "underwater" mortgages ... an astounding 67.2%.
One suggestion: In "problem areas" like LV, the tax law should be changed to eliminate capital gain taxes on the purchase of bank owned homes by investors (homes to be used as rentals). When these homes are eventually sold (years later) no capital gain taxes are owed. This might help stem the free fall in home prices.
