“For Sale” signs now litter American communities. According to the U.S. government, 2.8% of homeowner houses and 10% of rental houses are now unoccupied, or a total of 17,890,000, which includes 4,558,000 seasonal vacation homes. This does not include occupied homes that are for sale. The historical average for vacant homeowner houses from 1995 to 2004 was only 1.7%, so around 1.4 million more houses are vacant today than in 2004.
