A 41-story New York office tower that Jared Kushner’s former company purchased 11 years ago — and that has since been a source of much financial trouble and political controversy — will be sold to a Canadian company under a deal announced last week.

The announcement has been expected for weeks, after Brookfield Asset Management of Canada said in May that it was negotiating the terms of such a deal.

Still, the finalization of the purchase of 666 Fifth Avenue marks a turning point in a saga that has dogged Kushner from the moment he became a senior White House adviser to his father-in-law, President Donald Trump.

Brookfield said in a statement that “financial terms of the transaction were not disclosed,” other than that the property will be owned by one of its real estate funds. The backing for that fund comes from about 200 limited partners, whose names were not released.

Kushner Companies declined to comment. Kushner’s lawyer did not respond to a request for comment.

Kushner withdrew from his role in running his family company when he joined the administration, and he transferred his interest in 666 Fifth Avenue to a family trust. Kushner has kept about 90 percent of his real estate holdings, according to an analysis last year by The Washington Post.

Don Fox, former general counsel and acting director of the Office of Government Ethics, said Friday that the companies should disclose details of the agreement to avoid concerns about conflicts of interest.

“I think it would be helpful to Jared and the Kushner Companies and beneficial to the public,” Fox said. “It would resolve a lot of questions that people in the press and the public . . . who are concerned about ethics in government are going to have.”

Kushner approved the purchase of the building in 2007, shortly after he took over the company founded by his father. Kushner Companies paid $1.8 billion, the most ever at the time for an office building in the United States. The deal quickly soured as the financial crisis hurt real estate values, and occupancy rates dropped.

In 2016, at the same time Kushner was helping to run Trump’s presidential campaign, he simultaneously oversaw the family company and talked with potential foreign investors about becoming partners in the building, hoping to find a way to pay off a $1.1 billion debt that is due in February 2019.

But potential deals with investors in China and Qatar fell through. The company’s search for a partner became more difficult as sovereign wealth funds became increasingly wary of working with a firm tied to Kushner, whose business dealings have been examined by special counsel Robert Mueller.

Kushner Companies owns the office portion of the tower. The Wall Street Journal reported that Brookfield will pay enough for Kushner Companies to retire its $1.1 billion debt and buy out its partner, Vornado Realty Trust, which owns the retail portion of the building. Vornado’s chief executive, Steve Roth, is a longtime friend of Trump and partner with the president in some real estate deals. The entire building will then be transferred to Brookfield.
