Should I upgrade this kitchen?

[Byron W.]

I could use some advice. This is the kitchen in one of my vacant units that's on the market at the moment. Everything works as is. I'm wondering should I make any upgrades to the kitchen? And if you do suggest making some upgrades, what would you suggest paying?

This is a 5 bedroom 1/2 bathroom apartment (1350 sqft) in what I would consider to be a C+ borderline B neighborhood.
