Development and investment firm Naftali Group has agreed to buy the 33-story luxury apartment building at 800 Fifth Avenue for more than $800 million.

Naftali has entered a contract to buy the 208-unit property from Spitzer Enterprises — run by former New York Gov. Eliot Spitzer — and Winter Properties, according to a source with knowledge of the deal. Bloomberg first reported the news.

Newmark (NMRK)’s Adam Spies and Doug Harmon brokered the sale. Spitzer and Newmark declined to comment, while spokespeople for Naftali and Winter did not immediately respond to requests for comment.

In January, Spitzer and Winter put the building between East 61st and East 62nd streets up for sale with an expected value of as much as $1 billion, Bloomberg reported.
