I have seen Sellers get more than asking price once they made minor repairs, adding accents like wainscoting or crown molding, neutral paint and staging the home with furniture they already have.
"You" have to make it happen in this market by putting in some extra effort!
If not going with Realtor, simply put, you must to research your market area & amenities and what is selling and for what amount. Next, make sure you declutter, stage your condo and price it right.
Unfortunately, as with all sellers you will be looking at longer market days. But if you are competitively priced and in a good location (remember "location, location, location") you should have no problems!
Well like everyone else said below. You need to price it very competitively, make sure it shows like a model. The key will be location as well as condition and price point. Condos will still sell taking these three points in consideration.
Despite proclamations of the demise of the Chicago real estate market, things continue to sell if they are priced responsibly. Last week I sold two of my listings and represented two buyers with purchases.
Unlike several previous answerers I don't advocate taking the most recent comp and pricing your place lower or simply undercutting the competition with a lower price. Bear the competition in mind but make sure that you line yourself up with a knowledgeable real estate professional versed in your specific location and also adept at taking advantage of all current resources to market and sell your home (a property specific website, professional pictures of the home, a video tour of the home, aggressive and extensive on-line marketing, and the capacity to steward the listing of your home to a timely and successful transaction).
Having said all of this a good portion of the success of any realtor you choose to market and sell your home relies on your place - where is it located, what size, what level, how is the floor plan, is there parking, what are the finishes, and how does it show.
Best of luck determining the direction in which you go and the professional with whom you align yourself.
