Well off baby boomers are forced to withdrawal funds from their 401k and their kids can't afford housing. So, the parents buy a nice house for their kids and rent it well below market and use the depreciation of the rental property as an offset for their 401k withdrawals. This is why we see more and more house sales in the retirement age and less and less to the young
Eventually the young inherit the house at the current appraised market price once the parents die.
This helps the housing market not crash right away and eases the next generation's struggles.
Happening in all major cities.
