Purchasing a home may be the single most important investment of your life, and possibly the largest purchase you will ever make. When you are dealing with hundreds of thousands of dollars, it may be a good idea to use a Realtor with experience, a fine knowledge of the area, education, and aggressiveness. An aggressive Realtor that knows how to negotiate the price of the home with you effectively may be the single most important factor when getting a good price on a home.
