Sure, it’s a buyer’s market in New York City, but proceed with caution. Any price comparisons need to take monthly common charges, or “monthlies,” into consideration.

Monthlies — which typically include maintenance fees, taxes and any assessments imposed for building improvements — vary depending on the circumstances of a given building and unit. Localize.city, the real estate search and data site, recently analyzed how the charges in one-bedroom apartments compared among New York neighborhoods, and shared their findings with us.

The researchers looked at the more than 32,000 New York City listings on their site and isolated the common charges as specified in each one-bedroom available for sale as of Nov. 5. (Neighborhoods with fewer than 10 listings were eliminated, which took all of Staten Island out of the picture.)

Not surprisingly, the study found that median monthlies were highest in expensive areas, where higher values translate into higher taxes, and where buildings are more likely to have amenities and staff that need to be paid for. NoHo, where the median list price for one-bedrooms was $1.8 million, had the city’s highest median monthlies, $1,876 a month. The lowest were just $278 a month in Ditmas Park , Brooklyn, where the median list price was $499,000.
