A whopping 28.6 percent of homeowners with mortgages owe more on their loans than their homes could sell for, according to quarterly data released Tuesday by Zillow, a real estate website. That's up from 26.8 percent in the second quarter. Home values declined only 0.2 percent from the second quarter but were down 4.4 percent year over year.

The rising percentage of homes with "negative equity" or "underwater" status is due largely to how long the foreclosure sale process takes rather than home value fluctuations, said Zillow chief economist Stan Humphries. Prior to the "robo-signing" scandal around foreclosures that came to light in 2010, the negative equity rate hovered in the 21 to 23 percent range, but has been in the 26 to 28 range since due to added delays in foreclosure sales. While the rate of foreclosures is dropping, the time required for foreclosures to sell has lengthened.

"We're in uncharted waters," Humphries said in an interview. "More than one in four homes underwater and about 9 percent unemployment is a recipe for more foreclosures."

Homes with underwater status are often considered risks for future foreclosure, since owners could have trouble refinancing or selling and may opt for a foreclosure via "strategic default" if they feel they will never regain their lost equity.

Humphries estimates that home values will bottom out in 2012 at the earliest and said the foreclosure market will remain "robust" for the next two to four years.

In several cities, more than half of all homes with mortgages are underwater, including Phoenix (66.2 percent), Atlanta (58.7 percent), Riverside, Calif. (51.4 percent), Tampa (56.5 percent) and Sacramento (50.9 percent). Other big metro areas with a high percentage of underwater homes include Miami-Fort Lauderdale (46.7 percent), Chicago (46.2 percent), Cleveland (41.5 percent) and Denver (38.5 percent).

The seemingly endless housing industry recession has caused a radical shift in opinion around home ownership.

A new survey found that only 52 percent of Americans still consider home ownership the American dream, while 48 percent consider it more of a nightmare.

The survey, by Columbus, Ohio-based Home Value Insurance Co., found that one-third of respondents thought buying a home was a risky investment and 18 percent said they were "not sure" they'd advise a younger person to buy one. About 85 percent said they consider now a bad time to sell but a good time to buy, while 23 percent of owners said they were likely to sell within five years.

The American dream is one that dies hard. A survey down earlier this fall by Trulia, a real estate portal, found that 70 percent of respondents still consider home ownership the American Dream, while 21 percent disagreed. (Source: MSNBC)
