Whatever the Boomers are going to start doing, the majority of them have probably already done it. I'm the last of the Boomers, depending how you measure, and typical retirement age is single digit years away for me. The first of them started whatever they were going to start doing close to fifteen years ago.
The big trick is that a lot of systems right now for older folk are built around taking over legal custody of their home, as payment for end of life care or for living money because boomers didn't save for retirement. I don't think we are going to see boomer housing turnover to younger generations. The boomers broke basically every system and process designed to let the next generation get on their feet.
But if they are sold to people who then rent it out, instead of selling it as a home, it has reduced the stock of housing. The game being played is to try and force as much of the US as possible to be renters instead of owners.
