A patch of marshland for sale in the US as a “private island” is making house-hunters giggle. 

The one-acre island is part of the Chain O’Lakes water system in Illinois. 

Despite its grandiose listing description, the island looks like it could sink into the river at any moment. 

A handful of derelict timber shacks and the remains of a jetty indicate the island was once somebody’s waterfront escape. 

Aside from a few established trees, much of the island is taken up by reeds and marshland.

The property is listed online with an asking price of $US200,000 ($306,000). 

The listing promises a wealth of opportunity. 

“The potential here is as vast as the surrounding waters – whether you’re looking to create a secluded retreat, a one-of-a-kind vacation rental, or an unforgettable family getaway,” the advertisement reads. 

However, buyers are warned to conduct their own due diligence before plunging into a business opportunity. 

“The property has established electricity (condition unknown), and there may be potential grant opportunities able to assist in rehabilitating the island,” the listing says.

The island last sold in 2020 for $US50,000 ($76,000). 

It was listed at the start of June for $US250,000 ($382,000), but the price was recently reduced. 

The property listing attracted attention on Reddit, where househunters chuckled over its waterlogged appearance. 

“$250k for a 1.22 acre private island! … 1.21 … 1.20 … buy quick!” one user joked. 

“This real estate agent isn’t very good – they forgot to mention the six private pools!” another commenter quipped, attaching an aerial photo of water ingress. 

Many social media users expressed concern at the possibility of flooding. 

“Usually, when real estate agents say ‘will go quickly’, they mean it metaphorically, not that the actual land will disappear in the next shower of rain,” a person wrote.
