Effective salesperson (ask them for their sold data: how many properties have they sold in the last year what is their sale price to original price ratio, etc ... if you want i can help you decide on the realtor as i have access to their history info ... find me here: website http://:www.territoryre.com and let's chat)
Ask the agent(s) to send you examples of each of the above and ask that they explain what they will do different than any other broker (what is their competitive advantage).
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.
Since all Real Estate is local, rather than this forum you should talk with a local agent...or more than one if you want multiple opinions. I'm in the Lexington market and things here are about the same, maybe a little better, than last year. Well priced properties are going under agreement immediately and overpriced properties are sitting on the market.
A word of warning--be sure you are pricing it right. The worst thing you can do is over price. Buyers are tougher than ever. I hope you have a trusted real estate professional helping you.
