511 S Main St presents an opportunity to acquire a single-tenant bank property in Harrisburg, Illinois with an absolute NNN lease structure. The offering is backed by a banking institution reported in the marketing materials as having approximately $2 billion in assets, providing investors with a credit-oriented tenancy profile and a lease structure designed to minimize landlord responsibilities. The property includes three drive-thru bays and an on-site ATM, features that support customer convenience and ongoing branch operations. Located along South Main Street, the property benefits from a position within Harrisburg's established commercial corridor, providing visibility and access to local residents, businesses, and daily traffic patterns. The branch serves a community base supported by surrounding households and consumer activity within the immediate trade area. Marketing materials indicate population estimates of 5,583 within one mile, 8,966 within three miles, and 10,458 within five miles of the property. The offering is further supported by reported branch deposits exceeding $5 million and a remaining lease term of seven years. Renewal options reportedly extend occupancy potential through October 2042, creating a longer-term investment horizon for prospective buyers. The combination of a net-leased structure, established banking use, drive-thru functionality, and renewal option framework positions the asset as a potential passive investment opportunity within Southern Illinois.
