Some of the best things that you can do are the following: Paint, trim, landscaping, changing out light and faucet fixtures, new flooring(carpet/hardwood), and bath vanities. Some towns do not require permits for switching out kitchen cabinets and counter tops(you'll have to check with yours). The aforementioned improvements can literally transform a house and you won't even recognize it afterward. In addition, these are low cost repairs and you can do them yourself. Hope that helps.
