Propertyshark.com recently released its NYC Walk-up Apartment Report for the second quarter of 2007, and the square footage stats are worthy of note.

The report, which focuses on the sale of the city's walk-up apartment buildings revealed that the price per square foot of walk-up buildings increased 27.59% to $187 since the second quarter of 2006.

So, we did the math, and that means that these buildings were selling for just under $140 per square foot back in ’06? Where’s the Delorean when you need it?

Other stats of note from the report:

• Total sales volume for NYC walk-up apartment buildings was $1.4 billion in the second quarter.

• The average sales price for a walk-up apartment rose 9 percent from the first quarter of 2007 to approximately $2.5 million.
