Well, obviously I'm thousands of miles away, so I don't know a realtor in your area, but my husband is a real estate broker and I can offer you the following tips:
1) the most important thing is PRICE. If you aren't priced right, you can have the best property in the world and it won't sell. If you don't get traffic and offers within the first 10 days, you are priced too high. You'll get the best price if you hit the market at the right price. Do not be delusional about what your condo is worth. An experienced realtor can help you price the condo where it needs to be in order to sell quickly.
2) Clean and de-clutter so the space looks as large as it can.
3) If there are any small issues that need fixing, fix them before listing your condo. Anything that would catch a buyer's eye and make them think, "Hmm, I'm going to have to fix that" may cause them not to offer on your condo, or may make them low-ball offer.
4) The best way to choose a listing agent is to look at signs in your neighborhood. Chances are, you'll see the same names over and over. Call all of them and ask them to make a listing presentation to you. This is free of charge, and a good opportunity to see who gives you constructive feedback regarding your property, what kind of marketing they will do for your property, and what their track record is for sales in your area. Make sure they will list your property on the MLS right away.
5) Do not offer less than the standard commission. I can't stress this enough. If the typical commission in your area is 6% and you offer 5%, buyers' agents are not going to be super motivated to show their clients your property. And even if they do, they might say, "Well, are you SURE about this neighborhood?" or something like that - in short, they may try to steer their clients away from your property. Offer the full commission to avoid this type of scenario and give your property the best chance of receiving a lot of traffic.
Best of luck to you! I hope your property sells quickly!
