Case in point, a recent report from Zillow, the real estate website, shows the share of homeowners across the country who are underwater on their mortgage is 9.1%, falling below 10% for the first time since the housing market collapsed more than a decade ago. Good news, since the average U.S. home lost more than a quarter of its value when the market crashed, Zillow says, sending millions of homeowners spiraling into negative equity – in other words, their homes' values were lower than their mortgage balances.
