Not sure how exactly they would do that but I can think of a few ways that would help prevent mass foreclosures.

It is not where the masses want to live.

@JD MartinI haven’t drank the kool-aid (millenials, look up Jim Jones-mass murderer) on Kiyosaki predictions.

The mass exodus from California is causing bidding wars left at right at the moment.

Or at least come en-mass?

I definitely understand how making this a mass strategy could get you into trouble.

Agents and NAR and the MLS keep tripping over themselves when critical mass has built up enough that in 5 years time it is going to be a much different landscape.

I do not believe the fed will allow the mass evictions or foreclosures we saw in 2009.  

Which also means they would not become landlord en masse like folks that was born in 1950-70.Since our financial regulation indirectly has financial bias to support working marrying couple (ratio of income to rent is now 1:4.5 in many cities) before they even able to apply mortgage then the number of mortgage application would be less. 

The recession from 11 years ago was caused by irresponsible lending and an overvaluation of real estate in many major markets, leading to mass foreclosures.
