Market really up?

The reno was done by the 2008 buyer. The 2010 buyer just painted.

01/17/2008 Previous Sale recorded for $1,450,000.
03/10/2010 Previously Listed by Sotheby's at $1,595,000.
09/14/2010 Previous Sale recorded for $1,595,000.

05/14/2011 Listing entered contract.
07/08/2011 Sale recorded for $1,750,000.

This came up before, I think when the 2010 buyer put it on the market after living there only two months.
