The third quarter Manhattan real estate market displayed much the same tendencies as the second quarter: inventory declined and sales increased, according to all of the quarterly market reports. Sales increased, in fact, to 3,837 sales, the second-highest level in 24 years (coming in second to 2007). The people of PropertyShark have, as usual mapped all of these sales?take a look at the uptown sales in the screenshot above. The map shows average price per square foot and number of unit sales per building. The darker the dot, the higher the price; the larger the dot, the higher the number of sales per building.
