NYMom, if your spouse wants to live in LA, there are big beautiful private lots with views which are cheaper than Pasadena (more in line with Poway’s prices and even below) in Diamond Bar and Chino Hills. Only problem is heat and necessity of AC (93-103 at least 6 mos yr) and distance to relatives (over 40 mi to N. Hollywood). But that’s not as far as Poway.
No villagey feel up there, though, but nice modern shopping available and good access to Fullerton, Anaheim, Brea and even as far as Irvine (since your spouse is a finance guy).
It feels like the country out there (due to hundreds of acres of dedicated open space) but is city-close.
