A modern four-acre, oceanfront estate in Montauk, New York, has been listed for sale for $21 million.
The owner is Michael Hirtenstein, a real estate investor and telecom mogul. He purchased the compound, which is comprised of two separate, contiguous lots, in 2013 for a combined $13 million, according to PropertyShark.
Mr. Hirtenstein rented out the property periodically over the last several years, according to data from Zillow, for as much as $150,000 per month in the summer of 2015. It was listed as a rental as recently as March 7 for $80,000 per month. That listing has been taken down since it went up for sale on Monday.

The estate on Old Montauk Highway was rented out last summer by dating website Tinder in order to throw parties for members of its invitation-only Tinder Select service.
The property, which has a 5,500-square-foot main house on one lot and a 2,400-square-foot guest house on the other, was designed by James Biber, leader of Biber Architects, and Pentagram Design.
The contemporary design of the houses, which feature floor-to-ceiling glass walls that allow for extensive views of the ocean, set the compound apart from its more traditional neighbors, according to Gary DePersia of Corcoran, listing agent for the property.

"We are always going to be a traditional-based modality out here," Mr. DePersia said of the Hamptons area. "But certainly in the last five to 10 years, we have seen a big swing to modern houses."
The main house has two bedrooms and four bathrooms, as well as a step-down living room, a screening room, a wine cellar and a skylighted-gym. The master bedroom has a second-level sitting room with access to a rooftop deck and wraparound terrace, according to the listing.
The two-bedroom, one-bathroom guest house includes an eat-in kitchen, lounge and deck. Along with the main house, it was built to withstand hurricane conditions.

The property also features an infinity-edge pool, hot tub, outdoor shower and access to 300 feet of ocean frontage.
A number of celebrities have homes in Montauk, which is known for being more laid back than its South Fork counterparts, such as Ralph Lauren and Paul Simon.
Mr. Hirtenstein could not be reached for comment.
