Since I do not know your neighborhood and the homes there this question is tricky. Most of the time this investment will pay off IF THE IMPROVEMENTS are done well. Nevertheless, this may not be necessary in your case. What I do with my clients and most of them have homes over 1 million and do not like to spend even 100 dollars, is to first make the inexpensive fixes such as declutter, rearrange the furnishings, paint the front door if necessary, paint rooms or trim on the house. The home will be much improved for under 1000 dollars. If you have a friend that is good with design get her involved. Lastly, look at the other homes in your area and see if most of them have up-to-date kitchens and how your house ranks against them. If most of them, in your price range, have this and your home doesn't have a significant advantage in say having a larger yard, nice master bdrm, etc, then yes you should make that investment or the costs to you in that final sales price will be much more than 5000 dollars or worse, you may not sell at all.
