Second-quarter sales prices fell nearly 20% in a year, while sales volumes drop like stones. The number of months on the market now doubles the decade's average.

The Manhattan residential real estate market showed little sign of recovery during the second quarter.

Some of the reports attributed the second-quarter price drop-off to sales back in early 2008 of high-priced units at The Plaza and 15 Central Park West. Some apartments at those luxury buildings sold for as much as $4,000 per square foot in the second quarter of last year. Greg Heym, chief economist at Halstead Property, said "adding that this year's third- and fourth-quarter sale prices should more accurately reflect the market."

To that end, Manhattan buyers are on the streets, as it's a great time to buy in Manhattan.
