Even so, the climate is better for renters in 2017 than in previous years, Mr. Broekhoven said.

“Numbers tell us that rent is still just as high as last year, but landlords are more likely to negotiate and there are more incentives being given,” he said.

Where are young professionals moving?

“They tend to go where it’s more affordable,” Mr. Broekhoven said: Harlem, Hamilton Heights and Washington Heights in Manhattan, Bedford-Stuyvesant in Brooklyn, and Astoria in Queens. (He noted that the Lower East Side was also a contender, but that prices there were rising.)

“People who team up with three or four roommates can end up in the city, but it’s a different way of living,” he added. “People that are fresh out of college or young that want to live on their own tend to go outside Manhattan.”

Where are prices falling?

Williamsburg, thanks in part to the L train shutdown, Mr. Broekhoven said.

“Prices are dropping there, and you can get a better deal,” he said. The shutdown is “still almost two years away, but people are thinking ahead.”

Where are prices not coming down?

TriBeCa and SoHo, “still pretty much the most expensive neighborhoods in Manhattan,” Mr. Broekhoven said.

And what’s the next up-and-coming neighborhood?

That’s difficult to predict because there are so many influencing factors, but wherever it may be, “there needs to be transportation,” Mr. Broekhoven said. “Transportation, safety and affordability are the big ones.”
