Erie scores 3.9/10, just below that ceiling, while Morrison, Fulton, and Prophetstown each come in at 3.8/10.

For nonpayment of rent, the required notice period is 5 days; a material lease violation triggers a 10-day notice; month-to-month holdovers require 30 days; and at the end of a fixed-term lease no notice is required under 735 ILCS 5/9-205.
