Belleville, IL — Mobile Home Park Investments

Belleville, Illinois is the county seat of St. Clair County and one of the Illinois side’s anchor communities within the St. Louis-Belleville metropolitan area. With a population of approximately 44,000 and proximity to Scott Air Force Base — the largest employer in southwestern Illinois — Belleville presents a distinctive and durable opportunity for manufactured housing investment driven by military workforce housing demand alongside a stable civilian employment base.

Belleville Market Overview

Belleville’s economy is uniquely anchored by Scott Air Force Base, located just 10 miles east of the city. Scott AFB is home to the U.S. Transportation Command (USTRANSCOM), Air Mobility Command, and numerous other military and defense organizations, employing approximately 14,000 military personnel and civilians. This creates a large, stable population of service members and DoD civilians who need housing — and who represent one of manufactured housing’s most reliable tenant demographics due to consistent income, regular reassignment cycles that favor rental over ownership, and established credit histories.

Beyond Scott AFB, Belleville’s economy includes healthcare (HSHS St. Elizabeth Hospital), government services, retail trade, and light manufacturing. The city serves as the commercial and administrative center for St. Clair County, providing additional service-sector employment that sustains manufactured housing demand.

Why Belleville for Manufactured Housing Investment

Scott Air Force Base is one of the most significant military employment anchors in the Midwest, and its workforce of active-duty service members and DoD civilians creates consistent, year-round demand for housing options at all price points. Many junior enlisted personnel and mid-career civilians find manufactured housing communities to be the optimal balance of affordability, home ownership opportunity, and short-term flexibility. The base’s operational continuity — USTRANSCOM is a critical national defense asset that is not subject to BRAC-style closure — provides long-term stability that is rare in markets dependent on corporate employers.

The Illinois side of the St. Louis metro also generally offers lower acquisition costs for real estate assets than comparable Missouri markets, reflecting slightly lower income demographics. This creates favorable entry cap rates for manufactured housing investors who can underwrite to Scott AFB-driven demand fundamentals.

Local Lot Rent Data and Trends

Lot rents in Belleville and the surrounding St. Clair County market range from $400 to $500 per month as of mid-2025. The proximity to Scott AFB supports rents at the upper end of this range for well-maintained parks with good access to the base corridor. Annual increases of 2 to 4 percent have been typical in recent years. Belleville rents are modestly below the Missouri side of the metro, reflecting Illinois’s slightly different income and housing cost dynamics.

Zoning and Permitting Landscape

Belleville and St. Clair County maintain manufactured housing regulations under Illinois state law and local ordinances. Illinois has a robust Manufactured Home Community Act (765 ILCS 745) that governs park operations, resident rights, and lease requirements. Operators should be familiar with this framework before acquiring parks in the Illinois portion of the metro. Existing parks in Belleville generally operate with established permits and non-conforming status.

Infrastructure: City Water and Sewer

Belleville is served by Illinois American Water and the Belleville Sewer Department. Public utility service is available throughout the city’s developed areas. The Illinois side of the St. Louis metro has generally reliable municipal water and sewer infrastructure, though as with any acquisition, investors should verify utility connection status and condition as part of standard due diligence.

Frequently Asked Questions: Belleville, IL Mobile Home Park Investing

How does Scott Air Force Base affect manufactured housing demand?

Scott AFB’s workforce of approximately 14,000 military and civilian employees creates consistent, year-round housing demand. Service members, particularly junior enlisted and NCOs, often prefer manufactured housing communities because they allow home ownership flexibility without the commitment of a traditional home purchase — important given the regular relocation cycle of military careers. DoD civilian employees add a permanent workforce layer that provides non-cyclical demand stability.

What is the Illinois Manufactured Home Community Act?

The Illinois Manufactured Home Community Act (765 ILCS 745) governs the relationship between park operators and residents in Illinois manufactured home communities. Key provisions include notice requirements for rent increases (generally 90 days), park closure notification requirements, and tenant rights in eviction proceedings. Operators new to the Illinois market should review this statute carefully and work with Illinois legal counsel.

How does Belleville compare to Missouri suburbs for acquisition pricing?

Belleville and the broader St. Clair County market generally offer lower acquisition prices per site than comparable St. Charles County properties, reflecting the income differential between Illinois and Missouri sides of the metro. This creates favorable entry pricing for investors who are comfortable with the Illinois regulatory framework and can underwrite to Scott AFB-supported demand.

Is there MetroLink (light rail) access from Belleville?

Yes. The Shiloh-Scott station on MetroLink’s Blue Line provides rail connection from the Belleville area to downtown St. Louis, midtown, and the Central West End. For manufactured housing residents who work in the St. Louis core, MetroLink access provides a transportation alternative that enhances the desirability of well-located parks near the station corridor.
