A 111-space mobile home park in Ypsilanti, MI. Everyday shopping is within a couple of miles.
This mobile home park carries 111 spaces on the registry, without a vacancy count to say how full it runs. FEMA's flood map puts this park in zone X, outside the mapped special flood hazard area — one less financing or insurance hurdle than a park in a hazard zone faces. Internet is a strength around here: about 100% of homes in town can get 100/20 Mbps service, much of it fiber.

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: Michigan requires a park to measure water use accurately and consistently before it can bill for it separately — billing for water without metering is an unfair practice — and suspected water-tariff violations get referred to the Public Service Commission (MCL 125.2328). 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 Cosmonet-Greenbriar LLC?
Cosmonet-Greenbriar LLC 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 Washtenaw County is $1,656/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 Cosmonet-Greenbriar LLC?
Michigan has no mobile-home-specific rent law — no cap on the amount, and no dedicated notice period. A lot-rent increase is treated like any change to a month-to-month tenancy under Michigan's general statute (MCL 554.134), so check what your own lease requires.
