If MBAs and financial models can predict slowdowns, we won't have them at all. If anything ML models will exacerbate the situation IMO and they probably relied on them too much and bought more than they should. Of course what I said is also a projection (without even an ML model), so that is not accurate either :)
Their risk model should really account for the possibility that housing prices go down. I mean, there were famously in 2008 banking firms whose models didn't even allow for that.
