“How much should a person list their home for relative to the value?”
To get the most activity and leave a bit of negotiating room, the optimal amount is about 2% over value, except for higher price ranges.
If your home is valued over $1,500,000, I recommend you list about 3% over value. If it’s over $2,500,000, then try about 4%.
Of course, there’s the other option: Value Range Pricing. In that case, you want to use a range of 5-10%, with the value (as you believe it to be) around the middle of the range.
