As these others have said, there is no general answer to your question; any advice you base your decisions on should be after careful consideration and only at the advice of a real estate professional who is familiar with your specific market. Condo sales are different than traditional, single-family housing in that buyers are often buying into a lifestyle concept as well as the property. Unfortunately, much of the appeal of that lifestyle is in the hands of the community itself and not with the individual owners. To say the market will pick up is true, but the pace of that pick-up is what's at issue, and it varies greatly. Some neighborhoods will rebound in 24 months, others will take a decade. That's why I can't stress enough the value of a professional counseling you through the process.
Best of luck to you for what's ahead!
