My advice to people who have asked me about condos is to never buy a 1 BR condo. They always seem to be the absolute hardest thing to sell (you don’t specify the size of the one you are considering).
As marion and doofrat have pointed out above, what you really want to get is one as close to feeling like a single family home as you can. Attached garage, loads of privacy, fewest common walls. When we owned one, we bought a 3 br 2 ba 1 car garage townhouse (we had the upstairs and downstairs) with just 1 common wall. It sold very easily when the time came.
