Here is more sales data for 04/01 - 07/01, for the four years, 2004 - 2007.

Whereas the other data (below) covers just the downtown Boston real estate market, this data includes all reported sales in ALL Boston neighborhoods, but only includes one-bedroom units.

(The reason I only did the three months from 04/01 - 07/01 is that the data is from LINK and they truncate the results if there are more than 600 sales ... which there were, during the entire year, each year.)

2007, 308 units, average $402,588, median $380,000, $565/SF, 73 average days on market
2006, 349 units, average $407,570, median $396,000, $585/SF, 62 average days on market
2005, 416 units, average $403,347, median $388,000, $586/SF, 52 average days on market
2004, 421 units, average $377,020, median $359,000, $534/SF, 62 average days on market

As you can see, there has been a big drop in volume (25%). This, as much as anything, is probably due to two things: lack of new development closings, and the exit in the market of first-time homebuyers, this year, due to market uncertainty. (For example, 2005 & 2006 had a lot of closings at 15 North Beacon, which raised the s, that spring.)
