That looks unfinished.
I agree, it looks like the people ran out of money to complete the basement project and decided to paint the ceiling rafters, think it looks terrible. Asking a realtor is much like watching those TV home design shows. They will tell you want is trendy today regardless of price/practicality or functionality. Trends change and in a year or two something else will be 'trendy'. Unless you are doing this to prepare to sell your home in the next year, I would do what you want to do and enjoy your finished basement.
