Dm, you love trulia answers! Don't your agents answer any of these questions - that is indeed why you are paying them a % of your sale price (lots of money) ;)
I did a quick market snap shot for condo's- total sold from 5/8/06-5/8/07 and below are the statistics:
98 sold, average sale price was $535,140, average days on market were 105, and the sale price to original price ratio was 98%, which means the properties were being discounted 2% from original asking. The largest number of units out of the 98 (24 units) sold in the $600,000-699,999 price range.
Snapshot, total sold, 5/8/07-5/8/08:
63 units sold at an average sale price of $507,825, with an original to sale price ratio of 96% (which means properties have been discounted 4% off original asking price). Average days on market was 63 and most units sold in the $500,000-599,999 range.
