The nearest basics run 9–13 miles, a real but manageable drive rather than a walk. This isn't a flood-zone property — FEMA's map has it in zone X, outside the special hazard area. The surrounding town is well wired: about 100% of homes can reach 100/20 Mbps, much of it fiber. At 14 spaces, this manufactured home community is a fair-sized operation to run water and rent billing across.

Distances are straight-line, so the drive is longer. Internet and neighborhood figures describe the surrounding town — and the rent benchmark, wildfire rank, and tornado count the wider county — not this park’s own lots. The fair market rent is apartment-style rent (HUD’s area benchmark), not this park’s lot rent. Rent limits are not legal advice.

For residents
- Water billing: Illinois bars charging residents again for common-area water the utility already bills separately, and where common-area use isn’t separately metered, caps what residents can be billed at 80% of the total utility bill (765 ILCS 745/6.2). Check the math free with the water submeter calculator.
- Paying rent: ask the park office how they take payment. Parks that run on Lot Sidekick hand residents clear, itemized rent and water bills.

How much is lot rent at Sunny Hill?
Sunny Hill doesn't publish its lot rent anywhere we could find, and we won't guess at a figure. Call the park office to ask. For scale: HUD's FY 2026 fair market rent for a 2-bedroom rental around Jersey County is $1,218/mo — that's apartment-style rent for the area, and lot rent (the ground under a home you own) usually runs well below it. If you run this park, you can add your real lot rent to this page for free.
How much can lot rent go up at Sunny Hill?
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).
