What are some low cost/ high impact projects to boost appraisal?

[Joe M.]

Closing on a small 2 bed/ 1 bath house this week. It's in good condition. Kitchen is a bit dated, but clean and functional. Flooring is painted. Most of the windows, but not all have been replaced. Want to make sure the appraisal value comes back as high as possible on the refinance. Looking for some low cost/ high impact projects that can help boost appraisal value. The comps in the area wouldn't make sense to add a detached garage, an addition, or a total kitchen remodel. The house was priced right, but there is about 10k or 20k boost in appraisal value based on the highest selling nearby comp.
