According to experts at CNBC, when home mortgage debt rises, it usually means the real estate market is turning around, as more people seek loans to acquire real property of all types. Recently, it means that mortgage debt grows as banks foreclose on fewer homes, clearing less debt off their books. Goldman Sachs researchers found that by August 2013, 57% of all residential home sales were all-cash deals in which buyers obtain no financing. This is up from 19% in 2005.
