In the third episode of “Selling the City,” Netflix’s new Manhattan-based spinoff of “Selling Sunset,” the series’s star, Eleonora Srugo, attends an awards dinner for her brokerage.

In a scene that has become boilerplate in the crowded genre of real estate reality television, Ms. Srugo — wearing an $842 crystal-encrusted David Koma top that scoops down to her navel — is surrounded by both allies and adversaries as she makes a toast.

“This is not the City of Angels, it’s the city of empires,” she says, raising a glass of champagne. “So here’s to us. To breaking records and to building empires.”

One empire that “Selling the City” is building is the franchise itself. It’s the third spinoff for “Selling Sunset,” which is now in its eighth season and continues to pull in millions of viewers for each episode. “Selling the OC,” set in Orange County, Calif., began its third season in May; “Selling Tampa,” which featured an all-Black cast on the Gulf Coast of Florida, was canceled after one season.

The New York spinoff follows a team of agents led by Ms. Srugo, a broker for Douglas Elliman who was born in Israel and raised in New York City. She navigates backstabbing co-workers, cutthroat competition and the challenges, she says to the camera, of being single in the city. Her fellow agents include Jade Chan, who focuses on new development, and Steve Gold, a veteran of “Million Dollar Listing” who is often the only man in the room. All three are among the top-earning agents in New York City.
