Almost 1.5 million single family homes and condos in the U.S., roughly 1.52 percent, stood vacant at the end of the third quarter.

In addition, there were 10,291 vacant "zombie" foreclosures homes nationwide at the end of third quarter, representing 3.38 percent of all homes actively in the foreclosure process, according to the 2018 Vacant Property and Zombie Foreclosure Report from Attom Data Solutions. Fully 14,312 homes, 4.18 percent, were classified as zombie foreclosure in the third quarter of 2017.

"The number of vacant foreclosures is now less than one-fourth of the more than 44,000 in 2013 when we first began tracking these zombie homes," said Daren Blomquist, senior vice president at ATTOM Data Solutions. "Policy solutions such as land banks designed to mitigate the ripple effects of vacant properties on neighborhoods and cities have had a substantial impact, and a booming housing market in many areas of the country is lifting all boats.”

The states with the highest share of vacant homes were Tennessee (2.65 percent), Kansas (2.50 percent), Oklahoma (2.49 percent), Mississippi (2.47 percent), and Indiana (2.45 percent).

The metropolitan statistical areas with the highest share of vacant homes were Flint, Mich. (6.99 percent); Youngstown, Ohio (3.80 percent); Beaumont-Port Arthur, Texas (3.71 percent); Myrtle Beach, S.C. (3.70 percent); and Mobile, Ala. (3.69 percent).

The counties with the highest share of vacant homes were Baltimore City, Md. (7.83 percent); Genesee County (Flint), Mich. (6.99 percent); Saint Louis City, Miss. (5.93 percent); Bibb County (Macon), Ga. (5.73 percent); and Wayne County (Detroit), Mich. (5.60 percent).
