Most people buy one mobile home park. A select few buy a handful. Very few buy 10 or more. Meanwhile, there are around 40,000 mobile home parks that will need to be sold simply from the biological clock of the mom and pop sellers. There are not nearly enough buyers in the U.S. for the number of parks that will ultimately be sold.
What holds people back on buying more than one park is typically the capital constraint. While the industry is filled with "zero down" stories, typically the deals require 20% to 30% down. To me, house flipping is a low barrier real estate sector, not mobile home parks.
