Light fixtures can be replaced......key is to get a clean simple look and stay in budget.
It is difficult at this time to do a total remodel unless you purchased the house many years ago or got a great price and are looking to redo. If the house is empty....fresh paint and flooring is first....Remember most of the time buyers cannot see past the stained carpet, unusual paint colors and etc. So neutralize and brighten! Good Luck.
