This notoriously expensive Hamptons mobile home complex has yet another multimillion-dollar listing up for sale. 

Within the confines of the once-modest Montauk Shores, this unassuming three-bedroom abode is freshly for sale and looking for someone with $3.6 million to spend. 

The domicile is “literally moments to the sands and iconic surf of Ditch Plains” Beach, said John D’Agostino of Martha Greene Real Estate, LLC, who holds the listing. 

The quaint “oceanside bungalow with southern vistas” is a turnkey opportunity to have access to the miles of Atlantic coastline, which make the area a renowned surfing destination, D’Agostino added. 

“Fully replaced in 2016,” the dwelling boasts an open-format granite kitchen, laundry, an “expansive loft,” a first-floor primary bedroom and access to the Montauk Shores members’ club house — including its heated pool, hot tub and playground, among other amenities. 

Investors and deep-pocketed surfers alike have taken notice of the 199-home community’s prime proximity to the beach in recent years, during the course of which property values have risen exponentially.

That’s been transforming the nabe — once a retreat for blue-collar New Yorkers — into a place where trailers list for seven-digit sums. 

“The people who are buying in there [Montauk Shores] are no longer firemen from New York City who want to go surfing on the weekend, they’re people who have a lot of money for a second home who say ‘I want to be right where the surf break is,’” Dave Rutkowski, owner of John’s Drive-In, which opened in 1967 on Montauk’s main street, previously told The Post. “It’s wild to think that a trailer could ever sell for that much money.”

In the past 12 months, Montauk Shores residences with headline-making prices have included a single-wide trailer seeking $1.1 million, an 800-square-foot off-market number that sold for a record $3.75 million, and then a 2,150-square-foot property, which stands to shatter that if it gets the $4.4 million it’s seeking.
