I know in some areas they are easier than others. But the general consensus among the people I know who own them, as well as my own personal experience, is it's a very difficult boat to resell. Unless, it's an older boat. It also seems like of all the major boat brands BassCats depreciate the most. But when comparing the brands and having been to most of the factories, the quality and engineering of a Cat is second to none.
edit:I do own a BassCat
