It's important that you understand why you're selling. Your motivation to sell is the determining factor as to how you will approach the process. It affects everything from what you set your asking price at to how much time, money and effort you're willing to invest in order to prepare your home for sale.
For example, if a quick sale is your goal, this will determine one approach. If you want to maximize your profit, the sales process might take longer thus determining a different approach.
