it's a pain in the butt but you can do it (paired sales). Start with homes that have unfinished basements and compare them to those with no basements. Establish a good reference file. Once you have done that compare homes with unfinished basements to those with finished basements. After about 100 or 200 such pairs you will come up with a pretty good number to use in several different price ranges. OR
you can do what most appraisers do, guess at it. while cost information isn't to be used in the grid without market support, it too will provide a basis for establishing the upper limit.
As I said, in the median priced homes in my market, an unfinished basement has a market driven value of from $12 to $16 a square foot. Finish can be any where from $8 to $20 a square foot. Of course, in this market, basements are common and used as living area.
That's what they pay us the big bucks for....to be able to understand the market's reaction to all the items we normally adjust for in the grid. In my appraisal class I always use a range of values and suggest to the students that they need to develop their own set of adjustments.
