Finishing off a basement will add @ 10 % to the total value of the house if it really looks nice. I hope you are putting carpet down. Can you put in a wet bar? If not, even a dry bar adds a bit to the look!
Make sure you have wall plug ins. What about the ceilling? Can lights will do nicely. Add them if you can with the ones that can angle! Wiring needed, get an electrician.
Do not let the Tax appraiser know you did though! LOL!
My ex and I had the builders put in a fire place, do the ceillings, ruff in plumbing for the half bath. We did the rest with her fathers help. Did a wet bar, 1/2 bath, did not use hardly any space on the walls to give a bigger area. Had them do a cut out under the stairs for my recliner! Man, did we have the nicest family room in the hood neighbor!
