I work for one of the companies there.
From my experience with talking to numerous friends/colleagues out there who have kids,
none of them want to buy a house in SV area although they are OK with buying a condo if they don’t have any kids.
MM n general has a reputation of not having good schools in comparison with Poway/Scripps/PQ etc.
MM schools may be getting better but to change the public perception it would take many years..
