When interviewing realtors to market your home, remember that your relationship with your realtor will span a number of months and weather many stressful moments. Therefore, you should hire a realtor not on the basis of the price they recommend for your home, but rather on the relationship you feel you can build with them.
Do you think the realtor is trustworthy? Will they work hard for you? Do you like them? Can you confide in them? Do they understand your motives? Do they have a grasp of the market?
A good realtor will work with you to get the best price for your home that the market will bear; a good realtor is one that you can work with over time.
