Eagle is the Treasure Valley's premium address, and the numbers say it plainly: the metro's highest median sale price, its largest homes (the median Eagle listing is about 2,946 square feet, the biggest of any valley ZIP per Realtor.com May 2026 data), and a median household income of $122,894 (ACS 2024) — roughly 1.5 times the Idaho median. The city sits where the Boise River splits into two channels, with downtown on the north bank and the foothills rising behind it.
What buyers are actually buying here is land, river, and quiet. Lots run larger than Meridian or Boise, the river corridor is threaded with pathways and golf, and downtown Eagle still operates at small-town speed — a Saturday market at Heritage Park, one main street, no big-box sprawl in the core. The foothills add something no other valley city has: Idaho's first wholly in-state wine appellation, the Eagle Foothills AVA, designated in 2015.
And growth has consequences worth naming here more than anywhere else in the valley. Eagle's two master-planned projects — Avimor (annexed 2023) and Valnova (broke ground 2025) — are planned for up to roughly 15,000 homes between them over the coming decades. That build-out, and how to pay for its infrastructure, is the defining question in Eagle politics and a real input to any buy decision. We cover it straight in the growth section below.
