The share of millennials that expect to rent forever has nearly doubled in two years, to nearly one-fifth, according to an annual report from Apartment List. The rental listing site’s 2021 Millennial Homeownership Report found that, in 2020, 18.2 percent of millennials who don’t currently own homes expected to always rent, up from 12.3 percent in 2019 and 10.7 percent in 2018. Millennials are the largest generation and the report pegged their age range as 24 to 39. The report combined data from the U.S. Census Bureau’s Current Population Survey and Apartment List’s annual renter survey. Despite stereotypes of millennials not wanting to be tied down, of those who plan to never purchase a home, 74 percent said affordability was the main reason — more than double the share who said they prefer the lifestyle benefits of renting such as increased flexibility and avoiding maintenance expenses, Apartment List said.
