Make the improvements and changes before you set your listing price. The listing price is determined by the quality, condition, and features of your home. If you list prior to improvements, your price will not reflect the new value when your home is for sale. The real estate market expects prices to go DOWN after time on the market—not UP. It will not accept a higher price once your home has been listed. For example, if you decide you’ll replace your old carpet if your house doesn’t sell in a month you will lose money on both ends. You’ll lose with the lower listing price and you’ll end up spending additional money on the carpet anyway.
