30% of monthly median household income (~$1,846/mo) · rents above this line are typically considered cost-burdened.
Key Takeaways
- Affordable market: Home value to income ratio of 2.4x is well below the ~4.1x national average; supports talent attraction and family settlement narratives.
- Elevated vacancy: 12.8% vacancy rate. In resort, rural, and seasonal markets much of this is recreational/seasonal (second homes), not available supply; confirm the vacancy-by-reason split before treating it as a redevelopment opportunity.
- Broadly affordable rents: All 5 HUD Fair Market Rent bedroom tiers sit below the 30%-of-median-income affordability threshold (~$1,846/mo), a clear cost-of-living advantage for workforce attraction.
