(CNN) - A growing number of mortgage borrowers are keeping their heads above water.
That's according to a report from RealtyTrac.
The company reports 9.3 million properties, or 19 percent of all homes with mortgages, were "deeply underwater" in December.
That's down significantly from 10.9 million properties, or 26 percent, last January.
RealtyTrac defined "deeply underwater" as a borrower owing at least 25 percent more on their mortgage than the home was worth.
