Be careful of being overly optimistic.
In a competitive market analysis scenario, if one agent quotes a significantly higher price than others, that agent is probably not the one for you. The market doesn’t lie, so each agent providing a quote should be relatively close. If you list the house higher than market value, then drop the price later, the house will be what is called “market worn.”
The final selling price most probably will end up lower than if the home had been listed correctly in the beginning.
