The kitchen looks in keeping with the house imo. You could take all the magnets off the fridge/freezer perhaps - de-personalise is the way to help sell houses, so I've heard.
You could spend money refurbishing only to find that new owners don't like it and would rip it out anyway. Perhaps you could paint the bathroom cabinets white to brighten up that room?
I see you have sitting tenants in slide No. 18 - do they come with the property?
Do you think you know when you are going to die?
