Union City, CA Homes for Sale between $300000 and $400000

The $300000 to $400000 price point in Union City is where value meets variety. In this bracket, the dream of Bay Area homeownership becomes a vibrant reality, often featuring modern, triple-wide manufactured estates and beautifully updated condos that feel like a breath of fresh air. It’s the ideal range for buyers who want that extra room for a home office, a third bedroom for a growing family, or high-end finishes like farmhouse sinks and quartz countertops without the seven-figure price tag.

Whether you're eyeing the resort-like serenity of The Tropics (94587)—a premier 55+ senior community—or a lively, all-age park like Central Park West near the Union Landing entertainment hub, you’ll find homes that prioritize comfort. Many listings in this tier boast open-concept layouts, newer energy-efficient windows, and private outdoor spaces perfect for container gardening or weekend brunch. With the Union City BART station just a short ride away and proximity to major tech shuttles, these homes offer a strategic and stylish home base for anyone looking to stay connected to the pulse of the East Bay.
