 Not everyone has the same taste, so avoid the trends. Another thing is don't over-landscape the house. Don't flatten land. Don't do things that won't come back when you sell the home as far as equity goes. Avoid extreme colors and go with a paint that is more neutral. Replace burned out light bulbs as most home buyers flip switches to look to see what works. And lastly, make sure your air conditioner is set to a comfortable temperature.
