I just bought a new home(new to me) and now live part-time at Lowes. I was looking through their book section on home improvements and remember seeing that very article. Spend an hour there and you should find what I am talking about. Kitchens and bathrooms return the most, about 60-70%. The rest are all lower. That is why I am making my home improvements now, so I get all the return from them while I am living here. Besides, what you upgrade to, the prospective buyers may not like anyway.
