Millions of young adults who moved back with their parents thisyear could lead to an estimated $726 million in lost rent,according to a Zillow analysis, which noted that the ripple effects"could have far-reaching consequences for the housing market."

Amid high U.S. unemployment in the coronavirus pandemic, thenumber of adults living in a parent's or grandparent's home grew bymore than 2.7 million in March and April, said Zillow, adding that the vast majority of thosewho moved home — about 2.2 million — are from Generation Z and arebetween 18 and 25 years old.

Zillow said the 2.2 million Gen Zers represent anestimated $726 million in rent payments eachmonth — about 1.4% of the rental market at risk. "It is highlyunlikely that all leases will be broken and this full amount wouldgo unpaid, but it serves as a gauge of the potential impact onhousing," the Thursday report said.
