Premium market, smart picks: while Idaho trends above the national average, the gap between the most and least expensive cities here is wider than you'd think. Nampa at index 91 is the standout — offering meaningful savings without leaving Idaho (that's pre-tax, of course).
Premium market, smart picks: while Idaho trends above the national average, the gap between the most and least expensive cities here is wider than you'd think. Nampa at index 91 is the standout — offering meaningful savings without leaving Idaho (that's pre-tax, of course).
The obvious answer isn't always the right one. Exhibit A: Nampa rent up 4% over the past year. Rent in #1-ranked Nampa has increased from $1,502 to $1,561/mo over the past 12 months — a 4% increase. Rising costs may erode its top ranking over time. This is the kind of number that should get your attention.
Dive into Nampa's numbers: cost index 91 (20 points below national average), rent $1,561/month, income $72,122, and a home price of $408,658. The city's cost profile isn't flat — Housing is the cheapest category at 91, while Healthcare runs 98. With 114,268 residents, it balances mid-size city convenience with manageable costs.
Rent data is sourced from Zillow's Observed Rent Index (ZORI), which tracks the median rent across all active listings — not just new leases. This gives a more representative and stable signal than asking prices alone. Nampa: $1,561/mo, Boise: $1,703/mo, Meridian: $1,954/mo. The cheapest city here is $334 under the national median — that's $4,008/year in savings on rent alone.
The counter-argument is worth hearing: Idaho — pandemic migration boom has reshaped prices. The 3 cities we track here average a cost index of 101 and median income of $84,039. It's a clear buyer's market compared to national norms. The typical rent runs $1,739/month, which is $156 less than the national median.
Bottom line: Nampa leads this ranking for clear, data-backed reasons — but the "best" city depends on your priorities.
