Having statistics can justify single units as rental units is more practical as the MF.    

I can almost guarantee that they are not in it for the long haul like some small B&H investors.One of the things that I love about SoCal is that even if builders want to nut up, there are practically no empty lots near the prime areas left for them to build out, they can't build into the ocean, so the only place left to go is up, which they do but that is really expensive and time consuming, especially with CA building regs ... so regardless of if the market is super hot or just kinda hot (which is the SoCal equivalent of cold), there always seems to be a persistent shortage of housing here.

The more it hurts in practice or basic training the easier it is in the game. 

Not very practical.
