Ducks Ledges, a private island just a 10-minute boat ride from the coast of Maine, is on the market for $339,000.

Up for a private island on the northeastern coast of the US?

Ducks Ledges Island is a 1.5-acre landmass currently on the market in Wohoa Bay, Maine. The price: an attainable $339,000.

Billy Milliken, the island's owner and real estate agent in charge of the sale with Bold Coast Properties, told Insider that the island offers a lot to a new caretaker. Even though it feels remote when you're on the island, it is just a 10-minute boat ride from Jonesport, Maine.

"It's out there far enough that you're away from any noises and lights," said Milliken, who has owned the island since 2007. "There's a very dark sky out there so nighttime is beautiful."

However, to qualify as a potential buyer, Miliken says that interested parties need to stay a night on the island.

Being able to afford the price tag is one thing. But Milliken has an additional stipulation: Anyone interested in Ducks Island needs to be prepared to spend a night on the island and win over Milliken.

"I'm sticking to my plan in that to qualify as a buyer you've got to stay," he said. His reasoning is that he wants the new owner to see the value in the island's natural landscape, but also be willing to deal with its quirks.

Two parties have already completed the overnight request and three more are scheduled to visit in the coming days, he said. If more than one potential buyer is qualified, Milliken said that the deciding factor is his instinct.

"It's going to be coming from the gut," Milliken, 52, said. "When it's right, it's right. I'll feel it, and they'll feel it."

The island comes with a quaint 540-square-foot cottage featuring unobstructed views of the surrounding waters.

When Milliken bought the island, the original property had fallen into disrepair. "We tore it down and built a brand new one," he said of the existing cabin.

Given today's building laws in proximity to water, it's a rare find, Milliken said. Today it would be more challenging to erect the same structure on Duck Ledges.

"If you find a little island like Duck Ledges, you can't necessarily build a cottage on it," he said. Duck Ledges slips by because the island's structure predates new zoning laws, allowing for an existing non-conforming structure to stand legally.

What also makes Duck Ledges so unique is the lack of trees on the island, giving unobstructed views of the water. "You have a front row seat," Milliken added.

The cottage sleep up to four people.

The cabin is cozy, but will comfortably fit up to four people. There are two beds in the loft and, currently, Milliken said he keeps air mattresses for additional overnight guests.

Throughout the years, Milliken has shared the island with his family and close friends, who he said tend to make day trips rather than stay overnight.

The cottage is 20 feet from the edge of the water, but Milliken said it can withstand flooding.

The downside to being so close to the water is the risk of flooding during storms.

Milliken explained that the majority of bad weather takes place between October and May. He typically stays away from the island at that time because it's unfit for "man or beast," he said.

But despite a long stretch away from the property, the cabin remains intact. It was built with the rugged environment in mind.

"There's been three different times when the storm surges have come up to the cottage, and maybe under the cottage to a degree," Milliken said. "But, it's elevated. It's never, ever damaged the structure or the flooring."

Milliken said he's only ever used the space as a summertime getaway. Wintertime, he added, is no joke.
