If you go to Redfin and search on sale records for the past year for 2000 condos/townhouses you'll see 14. Some sold at a loss, and others that avg 4-5% appreciation over the past 5-10 years.... if they bought a long time ago. I tried to run the search in trulia and it didn't work.
But the true test is days on market and sales. If you look at current listings you'll see about 11 available with an time on the MLS of 104 days... and that doesn't include the listings that were taken off and added back to reset the avg days. Now to look at sales you'll see 14 sold in the last year, so you're looking at about 1 buyer per month, who probably takes the best of the available inventory at the best value. The best priced ones sell, and the higher priced ones sit on the market.
