Number one concern in a finished basement is air flow and water. A less than perfect job will create a mold problem. check Angie's list for local reputable contractors. We all have our favorite contractors but as real estate agents we are prohibited from "stearing" clients and customers so we are cautious. Ask a friend who did similar work ( preferable a few years ago) to see how well the job has held up. Think about access to your mechanicals i.e. access panels to water line shut off , etc , ceiling height and mold resistent materials and paint. great lighting is also a plus in a basement.
