Sebastian County is home to Fort Smith, Arkansas's second-largest city and the economic hub of the Arkansas River Valley. Fort Smith's economy is anchored by healthcare (Mercy Health, Baptist Health), manufacturing, logistics, and proximity to Oklahoma. The Sebastian County Assessor appraises properties across a market that has seen steady appreciation driven by Fort Smith's economic development and in-migration from more expensive regions. The 2026 appeal deadline is August 17, 2026.
Sebastian County Market and Assessment Patterns

- ✓Fort Smith west side: More premium residential; over-assessments common at upper price points

- ✓Greenwood: Growing southeastern Sebastian County community with new development
- ✓Barling: Small city within Fort Smith metro; diverse housing stock
