Houses that didn't sell
How Grosse Ile listings ended
Every house that left the market in the six months to September 2026. 10% came off without selling and hadn't come back.
The houses that stayed off had been on the market a median of 128 days before they came off. The ones that sold took 19 days.
Each house counts once. One that was withdrawn and listed again counts by how it ended, and one still on the market isn't counted yet.
Days on market, month by month
Each point is the median of three months of sales, ending with that month. Grosse Ile sells too few houses in a month for one month to be steady.

Before you list in Grosse Ile
Look up open permits
An old permit that was never closed turns up in the buyer's inspection or at the title company. Closing it now is usually a call and a final inspection.
Check the flood map
FEMA maps a coastal flood zone along the island's Detroit River shoreline, plus Frenchman Creek and the Thorofare Canal. If the home is in a zone, the buyer's lender will require flood insurance.
Order the final water bill
The township doesn't post its final-bill steps. Call the utility billing clerk at 734-676-4422, ext. 227 once you have a closing date. The clerk asks for at least the day before, so the read can be done around the time of closing.
