In Joliet, renters spend approximately 37% of median income on rent — above the 30% affordability threshold. This means your tenant base skews toward cost-burdened households who have no realistic path to homeownership at current prices. While this creates reliable demand, it also means tenants are more sensitive to rent increases and may have thinner financial cushions.

Renters here include a mix of young professionals not yet ready to buy and transient populations.
