As the housing market braces for more trouble, homeowners everywhere have been reduced to hoping things will someday stop getting worse. In some areas, foreclosures are the only thing selling. New home construction is nearly nonexistent. And CoreLogic, a data company, said Tuesday that house prices fell 7.5 percent over the last year. The federal government last year backed nine out of 10 new mortgages nationwide, and losses from soured loans are still mounting. Fannie Mae, which buys mortgages from lenders and packages them for investors, said last week it needed an additional $6.2 billion in aid, bringing the cost of its rescue to nearly $100 billion. Getting the government out of the mortgage business, however, is proving much more difficult than doling out new benefits. As regulators prepare to drop the level at which they will guarantee loans ?" here in Monterey County, the level will drop by a third to $483,000 ?" buyers and sellers are wondering why they should be punished simply for living in an expensive region. Sellers worry that the pool of potential buyers will shrink. "I'm glad to see they're trying to rein in Fannie Mae, but I think I'm being disproportionately penalized," said Rayn Random, who is trying to sell her house in the hills for $849,000 so she can move to Florida.
