The best thing to do is call a Realtor in your area and ask them to complete a CMA for you. They will ask you some questions about your Condo. If you need me to help you out by referring you to an agent in your area, then please let me know.
That's all you need to do is call a local Realtor and tell them you would like to have a CMA done on your property. They will compare your unit to active condos and recent solds to give you a market price. If you are planning on selling and that's the reason for the CMA ask them do give you a net sheet which would give you an idea of the costs involved with selling.
I hope that helps.
