Buyers shopping Solano County almost always end up comparing these two. They're right next to each other on I-80 and genuinely different. Here's the straight comparison.

The price story

• Vacaville: median sale price of $616,207, down 2.2% from last year, $355 per square foot, homes selling in about 38 days.
• Fairfield: median of $600,000, down 5.6%, $311 per square foot, selling in about 43 days.

Fairfield gives you more house per dollar on paper. Vacaville holds its value a little better and moves a little faster. Neither is "better." They're different bets.

The commute story

• To San Francisco: Fairfield runs about an hour and 40 minutes in real morning traffic; Vacaville is a few minutes more. Both are hauls. Both are done by thousands of people every day.
• To Sacramento: Vacaville wins big at about 40 minutes. If your job is in Sacramento or you want the option, Vacaville's location is the play.
• Travis Air Force Base sits between them, and both cities have large military communities.

The vibe story

Vacaville feels newer and more polished: Premium Outlets, a revitalized downtown with real restaurants, Lagoon Valley for trails. Fairfield is bigger, more diverse in housing stock, and has Rockville Hills and the Suisun Valley wine country on its edge. Vacaville skews "move-up family," Fairfield skews "more options at more price points."
