Also, economics for Millennials have been terrible. They're of course going to have a terrible time trying to get a down payment together as well as afford a reasonable mortgage payment. Even assuming they use a 3% down mortgage program, they then have no equity, and are locked to the property if they need to move/relocate unless they're willing to default on the property (which then keeps them out of buying again for 3 years).
EDIT: As someone who has seen deep into the real estate market, the game is rigged.
