"In my experience, Mountain View buyers fall into three clear camps — and the right zip code depends on your priorities, not just your budget. If top schools and a yard matter most, start in 94040. If walkability and transit access drive your decision, focus on 94041. If you want a short bike ride to Google or another major campus, 94043 is where I'd look first. Getting that match right saves you months of searching. Call me directly and I'll help you zero in on the right zip from the start."
