Excess: pack overstocked and off-season items. If you’re selling your house in the summer then put away winter wear and sporting gear. Try to return excess to the store you bought it from; they might take it back.
Mistake #3: Catering your house to a specific group (ethnicity, religion, age, taste, etc). To sell your house for the best price and more quickly, it must appeal to all segments. There’s the right buyer out there, you just don’t know which one.
