Why is Huntsville's housing market so different from other Alabama cities?
Huntsville has an unusually high-wage economy for Alabama — anchored by Redstone Arsenal (Army's largest missile/rocket center), NASA Marshall Space Flight Center, and Cummings Research Park (US's second-largest research park at 3,800+ acres). These defense, aerospace, and technology employers pay significantly higher salaries than Alabama's average, driving home prices well above Birmingham, Montgomery, or Mobile. Huntsville has been among the fastest-growing US cities by percentage — a trend not typical for Southern Alabama cities.
