You want the kitchen to look large, light and roomy. Clear the counters of all clutter. What that means is if you don’t use it every day get it out of site. Also take everything you can out of drawers and shelves and move it to storage. In short, make like you are moving. Because you are. You can almost count on buyers opening your drawers and shelves when they come to see your home. What you want them to see is space, and plenty of it, not your old pots and pans.
Consider paint. Paint is always the most profitable improvement. A fresh coat of neutral color paint on your kitchen walls will make them look spotless and new. Exactly the look you want. Pay particular attention to the sink. It should be absolutely free of stains and of course there should be no leaks or drips! If your faucet looks old and dated, consider replacing it with a new one, it will go a long way towards improving the look of the whole kitchen, for very little money.
Counter tops. If your counter tops are looking old and tired, you should consider new ones. Remember to stick with neutral colors though. Freshen up the cabinets. Replacing the cabinets is expensive and probably doesn’t make sense. But you can paint them, or put new, modern looking pulls on them for very little money and give them a fresh look. In short, buyers will be quick to notice any shortcomings in your kitchen. So you want to do everything you reasonably can to freshen up your kitchen and give it a new, open, large look.
