Everywhere we turn these days, the real estate headlines seem to announce the same thing: “Average home prices in Manhattan hit a new record.” Then a new one.

And it’s not just in Manhattan that home prices have been sky-rocketing month after month. In parts of Brooklyn and Queens average home price tags are boasting staggering numbers, as if what’s happening in Manhattan has started to take effect all over New York City. But is the real estate boom we keep hearing about really the rule in the NYC real estate market?

The map below reveals that, in reality, almost half of Brooklyn and Queens, together with several neighborhoods in Northern Manhattan show stagnation and even decreases in median home prices over the past decade (all values have been adjusted for inflation).

This portrays New York City as a very divided metropolis, but not necessarily split between rich and poor, but rather between the wealthy and the middle class. The latter, no longer able to afford homes in the formerly classy-but-affordable areas are being pushed toward South Brooklyn or Queens.

Note: The darker and lighter shades of green show increases while the red and its lighter shades show stagnation and decreases in home prices.

Manhattan: Where Should You Have Really Invested 10 Years Ago?

As you might have expected, the traditionally rich areas around Central Park have gotten more expensive to live in over the past decade. However, the increases in home prices there were quite modest, going up by only 20%.

Among the pricier nabes which registered the most significant increases were NoLita and Chinatown, where the median price per square foot jumped by 79% and 75% respectively, hitting staggering values ($1,813/sq.ft in NoLita and $1,216/sq.ft. in Chinatown).

The most remarkable changes in the Manhattan housing market took place, however, in Central and East Harlem.

In Harlem , the median home price per square foot was $709/sq.ft. in 2014, a 102% increase from $351/sq.ft.

, the median home price per square foot was $709/sq.ft. in 2014, a from $351/sq.ft. East Harlem saw an increase of 80%, from $468/sq.ft. to $842 sq.ft.

Brooklyn: Williamsburg Sees Median Home Price/Sq.Ft. Go Up by 269%

Brooklyn has always been divided into two parts – the Brooklyn of Carroll Gardens, Park Slope, and Brooklyn Heights and the rest of Brooklyn. The wealthy areas, under the impact of gentrification, continued to see their home prices rise between 2004 and 2014, but surprising transformations took place in less developed neighborhoods too.

In Williamsburg, part of the top ten list of the most expensive neighborhoods in NYC in 2014, the home prices sky rocketed from $275/sq.ft. in 2004 to $1,015/sq.ft. in 2014, marking a 269% increase.

Elsewhere in Brooklyn, however, several affluent oceanside nabes took a hit as a result of Hurricane Sandy. In Red Hook, the median home price per square foot saw a cut of 22%, from $526/sq.ft. to $413/sq.ft. In Brighton Beach and Basin Mill the decrease was 11%.

The biggest increase in median home price per square foot took place in what was considered the least developed neighborhood in Brooklyn, New Lots. Several housing programs here led to a 320% increase in median home prices, which reached $296/sq.ft. in 2014.

Queens: the Next Brooklyn?

In Queens, the biggest home price increases can be seen in the neighborhoods located at the border with Manhattan. These areas, albeit industrial, were still considered middle-class even in 2004. Thus, one can hardly talk here about a phenomenon similar to what Williamsburg is in Brooklyn.

In Hunters Point the median home price/sqft. went up by 132% between 2004 and 2014, from $399 to $924. The new price tag brings Hunters Point to the same level with Park Slope and other rich neighborhoods in Brooklyn;

Median home prices went up by 66% in Sunnyside reaching $664/sq.ft while in South Astoria they climbed by 53% ($625 /sq.ft. in 2014)..

The Bronx: A Declining Housing Market

With only a few exceptions, home prices throughout the Bronx have been following a descending path in the last decade. Concourse Village and Fieldston registered the most significant increases in median home price/sq.ft — 59% and 43% respectively.

NYC Caught between Sky-Rocketing Home Prices and Distressed Properties

For those looking for an answer to why we’re seeing this stark divide, our NYC Pre-Foreclosure map could help.

If we are to compare the home price map with a map of distressed properties, we can easily see that the areas which registered stagnation or decreases in median home prices are also seeing the most intense activity in pre-foreclosure or lis pendens filings. This is usually one of the main factors which trigger a decrease in home prices.

If a lis pendens is filed for a property, it means that the owner failed to make the monthly mortgage or tax payments. The next step after the filing is the foreclosure auction.
