So says the National Association of Realtors, here:
Walt Molony, a spokesman for the National Association of Realtors, says that the association’s estimates of the share of the market made up by all-cash buyers are lower than the others, at 31% in July, but that they’re still at an all-time high. ... Molony says that investors make up 35% of all-cash buyers (70% of all investors pay cash), while retirees who’ve built up equity in their homes or paid off their mortgages account for 12%. The rest include vacation-home buyers and foreign buyers.
