Excellent insulation
Insulation isn’t sexy, but when it’s 95 degrees in the summer or the mercury dips below freezing in the winter, your buyers will thank you for this, even if they didn't see the perceived or real value when they first signed the sales contract. Forget the entry-level insulation, and go for something that will really stuff the wall and the roof. While you’re at it, don’t forget the attic.
