However if your Kitchen looks bad you can do a very nice inexpensive change. They will more than likely take it out anyway.
But it may increase the value of what you have. Just be sure that increase is worth it.
I'm going to agree on doing minimal upgrades for aesthetic purpose of getting your house sold. Your tastes are not the tastes of the market or the potential buyer. Nobody can predict what they would want in their choice of flooring, cabinets, countertops, appliances, fixtures, etc. so don't spend money trying. Just do what might be needed to spruce up your kitchen so it shows well. replace missing/broken knobs and draw pulls, hinges. replace old and outdated fixtures to pleasant modern stuff that is tasteful. if your cabinets are old and grungy, maybe refacing or painting.
A new buyer will want to renovate the kitchen their own way, the higher end home they buy the more they will customize it for their tastes.
A good local real estate agent can help you to determine what needs to be done, if anything.
There is no formula. you NEVER get back dollar for dollar the cost of improvement to a home (just see how the math works for an appraisal).
Improving the property prior to sale is not done to increase value, but to bring the home up to good condition and to make it show better.
This is also not the real estate climate to over improve a property.
Installing a kitchen for the purpose of selling you home is one thing but expecting to recover the expense is probably an unreasonable expectation. There is a great resource that we would like to refer you to that does a great job analyzing common upgrates and their recovery amount which is based on the region of the country you live in.
It's a worthwhile tool that may provide you with information necessary to make your own decision.
