Lone Tree Valley runs east-west through Antioch's 94531 and 94509 — newer detached subdivisions mixed with active-construction phases. It's less hilly than Deer Valley, typically a tier more affordable, and a bigger mix of buyers (first-time, move-up, investor).
The housing stock here is 90s–2020s detached single-family — 3 to 5 bedroom homes on 5,000–7,500 sqft lots. Median sits around $699K, which is genuinely remarkable for Bay Area detached SFH.
Active new-construction phases in 2026 are adding roughly 100–200 homes per year — keeping inventory relatively steady and putting a cap on resale appreciation. Good for buyers; steadier for sellers.
Schools and parks drive Lone Tree appeal: Nelson Ranch, Mno Grant, and Black Diamond parks sit inside the neighborhood. Elementary feeders vary by phase — I pull the exact school for each address.
