J.S.
I would check with several realtors in your area, and ask for their advice. Since you're making the changes to get the best possible "bid" on your home, I would think that they would have the best advice for you. Let them know, too, that your house will not be "for sale" until next year. (Any realtors that start "hounding" you to put your house up for sale earlier, or to get your business are a "no go" for them. Choose someone else.) It's also a good way to get "connected" with the realtor who will ultimately be helping you sell your home. You can think of this as an informal interview process for your realtor choice.
Good Luck with your projects!
