The most expensive New York City neighborhoods in 2017, according to PropertyShark

Real estate site PropertyShark recently pinpointed where it's most expensive to live in the city now.

To compile the Q3 ranking, the company found median prices for residential properties sales closed between July 2017 and September 2017 (including single-family homes, condos, and co-ops).

Compared to last year, more Brooklyn neighborhoods made the list. Brooklyn has become one of the fastest growing NYC boroughs, which has strained its housing market in some areas.

To keep up with the city's rising population, Mayor Bill de Blasio implemented an affordable housing plan in 2014 that aims to preserve or create 200,000 units of housing with regulated rents by 2024. As of July 2017, 77,651 affordable units - with rents no higher than $3,461, depending on the household income - have been financed by the city.

Below are the 10 most expensive New York City neighborhoods, along with their median home sales prices, as of this fall:
