The question to ask yourself is, "can I still afford to live in the Coop." Your question could imply that you are in a tight situation financially. If this is not the case, stay put and keep building your equity. Appreciation will follow but that will be much further down the road.
Obviously, you are the only person who can make the decision based on your goals, blah, blah, blah. If you have to sell, then sell. Whatever you decide, good luck.
