FWIW, heard a presentation on "affordable housing" in Lexington a few weeks ago (bottom line - there is very little "affordable housing" in Lexington). But one point made was that there is little reason to expect a housing foreclosure deluge like in 08 and 09 because the prices have gone up so fast, that most borrowers, even if they lose their job, are not underwater like they were back then, and lenders who learned a hard lesson (I know, I represented a bunch of them) are much more likely to work with people to execute forbearance agreements and loan workouts rather than take a deed in lieu. Especially if there is still equity in the property, contrary to the general public view, last thing lenders want back is OREO property (Other Real Estate Owned)
All that being said, I am advising my kids to be very cautious in buying right now, you can always refinance a bad loan, but you can't recover money when you vastly overpaid, unless you are prepared to live in the home for a long time.
