8. Peoria, Illinois

Peoria stands out as one of the Midwest’s most affordable retirement options, with a cost of living roughly 24% below the national average and average 1-bedroom rents around $750 per month. Illinois does not tax Social Security income, which means that retirement dollars stretch further.

The city offers more cultural amenity than its size suggests. The Peoria Riverfront Museum, Bradley University, and the Spirit of Peoria riverboat create a lively community calendar. The park system is extensive, and the Illinois River provides scenic outdoor recreation within city limits. Healthcare is anchored by OSF HealthCare Saint Francis Medical Center and UnityPoint Health Methodist, both of which serve the senior population well.

For budget-conscious retirees who want access to real city amenities without coastal or major-metro price tags, Peoria delivers consistent value. The city’s strong civic identity and numerous senior centers make it easy to build community — a crucial factor for long-term retirement satisfaction that often gets overlooked in affordability comparisons.
