Several folks have already provided answers, and the advice is spot on about kitchen and bath upgrades - but not the high-end, big money path...particularly since your intention appears to sell the home soon. I also live in Serenada and would be happy to stop over to discuss pros and cons of what you are contemplating.
Depending on the condition of the flooring, that may need attention as well. But it doesn't have to be over-the-top, just some nice quality flooring can certainly help with the first impressions of folks walking thru the front door. And painting is one of the cheapest ways to get a fresh look.
Please feel free to give me a call 512-639-8838 if you would like another set of eyes on the project. I am in the throes of remodeling my home in the neighborhood, too.
