We don't sell parks and we don't have listings. This page is the registry data a buyer usually can't get in one place — park count, size mix, and the rent rules that cap your upside. For what's actually on the market, you still need a broker or a direct-mail campaign.

What a park this size earns
A park is priced on its income, not on the land. Take the rent it actually collects, subtract operating expenses to get net operating income, and divide by the cap rate buyers accept locally. At the median 10-space park here, every $25/month of lot rent across every lot is roughly $3,000 a year of gross rent — and at a 7% cap rate, a dollar of NOI is worth about $14 of value.
Run the numbers on a 10-space park
Before you underwrite anything here, check what the law lets you do with rent: the Illinois rent-increase calculator applies the 2026 rules to a park this size, and what other owners run their books on is worth knowing before you inherit someone's spreadsheet.
Rent rules that apply here
Illinois sets no statewide cap on lot-rent increases, and state law bars cities from setting a local one (50 ILCS 825) — but every increase needs 90 days' written notice, and a resident whose new rent would top 45% of household income can defer paying the increase for up to a year while listing their home for sale (765 ILCS 745/6, 745/6.4).
