While a jinxed Robert Durst awaits various legal trials and tribulations, a 10-year-old episode can be revealed about an apartment in Houston that he and wife, investment broker Debrah Lee Charatan, bought and made money on — without ever moving in.

In March 2005, Craig Nassi of BCN Development was in the throes of developing and selling more than 250 condominiums in an exclusive 32-story luxury tower at 3333 Allen Parkway in Houston that is favored by prominent residents and sports stars.

With floor-to-ceiling windows, the dramatic Royalton at River Oaks has a concierge, valet, fitness center, wine room, infinity pool, board room and private theatre.

The sales department received a call from Charatan in New York City, who wanted to buy a half-million-dollar 19th floor unit, sight unseen.

As it was “weird” for someone to not even visit the property, Nassi spoke to Charatan, who insisted on buying the pied à terre for herself. Documents were signed and the deal was completed through overnight services.

Not too long after, news crews staked out the tower and told the building’s staff that Durst was moving in. He was being paroled from prison after pleading guilty and spending several years locked up for two counts of bond jumping and evidence tampering.

He had already been acquitted in the death and dismemberment of his Galveston, Texas, neighbor, Morris Black.

“I told my staff to get extra security and that we were locking down the building so that no one could come in if they did not live here,” recalled Nassi. He also warned security to be on the lookout for a man disguised as a woman, as Durst was a known crossdresser.

Durst showed up at the building with his movers but the forewarned staff barred the doors and wouldn’t let him move in.

“I called up Debrah and said, ‘What is going on? You are switching occupants,’ ” recalled Nassi. “I had a fight with her, and she was aggressive. She said, ‘You can’t discriminate,’ `He’s not a bad person’ and `He’s a nice person.’

“And I said, ‘You don’t understand, we are trying to sell 200 units and if people get wind he is living here, we will never sell another unit,’ ” Nassi added.

“We weren’t doing the most kosher thing but anyone with large real estate investments would rather fight it in court. No one would elect to live next to a notorious murderer.”

Soon, Durst himself called and demanded to talk to Nassi, who put the call on speakerphone so the sales staff could listen, “because he has a screw loose.”

Durst demanded to know why he was locked out.

Nassi replied, “With all due respect, I read about you and you are from a real estate family and what would you do? Would you allow someone to come in and affect sales? I have hundreds of apartment to sell.”

“Well, G-d dammit, if you don’t let me in the building I will sue you and you will be sorry,” Durst warned, calling Nassi a “discriminating landlord.”

The next day Nassi was sued, and in 2006, settled out of court.

“I bought back the apartment and gave them an extra $200,000 to avoid going to trial. At the end of the day he never moved in, but they made money on the investment.” Charatan did not return a call for comment.

The ground lease on the former Bush Terminal office building at 130 W. 42nd St. is being recapitalized by Vanke Holdings USA in a deal that revalues the building at $125 million.

The transaction is expected to close this week.

Meadow Partners and Tribeca Associates bought the lease from American Properties in 2013 when the 85-year lease was created.

At the time, they paid $68 million and invested over $10 million in capital improvements including work on the historical façade, an expansion and creation of a modern, double height lobby, new common areas and building systems.

New leases are now being signed in the $70s, up from the initial $40s per foot. The surrounding towers are also set back providing great light and air to the 30-story building.

It is also on a block between Bryant Park and Times Square that is undergoing great transformation with new retailers, a recently constructed Hilton Garden Inn and newly resurrected Knickerbocker Hotel.

Douglas Harmon, Adam Spies and Kevin Donner of Eastdil Secured handled the deal.

As we first reported, this was the team that sold the Crown Building to retail maestro Jeff Sutton and Sandeep Mathrani’s GGP for $1.775 billion.

As we also first reported, Sutton and Mathrani will be selling the upstairs portion of the gilded tower to Vladislav Doronin, the majority owner of Amanresorts, along with local Michael Shvo.

The office floors may eventually become the city’s first Aman hotel and condominiums.
