Surging home prices have helped nearly two million homeowners get back above water on their mortgages over the past year.
RealtyTrac says during the first quarter, 9.1-million homeowners were seriously underwater on their homes.
That means their debt on the home exceeded the home's value by 25 percent or more.
The figure is down from 10.9-million a year earlier.
States with the highest percentage of seriously underwater homes included Nevada, Florida and Illinois.
RealtyTrac also found that fewer properties in the foreclosure process are underwater.
