Your theory doesn't explain why she's moving to Santa Cruz -- the schools are nothing special there.

If I wanted to live in Palo Alto the first two things I'd drop are the requirement for "walkable to downtown" and "my kids can bike on my street". Those are great attributes, but that's about half a million of additional house cost, and I think any rational person buying a home would drop those requirements if they truly want to live there. Adding on to that, I'd also suggest buying a fixer-upper, fixing it up, and living there (not flipping it).
