Thankfully, we are not at risk of another 2008 housing crash at this time - or at least not for the same reason.
The extremely (almost irresponsibly) abridged version of the 2008 subprime mortgage crisis is that banks were giving out loans to people who could not afford to pay them.
The similarly simplified version of what’s going on today is that people cannot afford to take a mortgage and aren’t getting them. Back in the bad old days loan officers would have given out the mortgages anyway to boost their numbers and the bank would have bundled that loan with others to hide it and started the game of hot potato. That isn’t what’s happening today.
That’s not to say a market crash the size of the '08/'09 crash won’t happen, or won’t happen soon, or won’t be caused by the housing market. It’s just that the circumstances that triggered the 2008 crash aren’t present today.
