To be honest, you won't see as many transactions as a REALTOR® does. An average family buys/sells Real Estate every 5 to 10 years. This is because when you buy a house, you're looking to create a home. You want your family to grow in it and you're only going to look to move from it if your family has outgrown it due to a baby on the way or kids growing up (upsizing) or the house has become too big due to the kids leaving for university or buying their own property (downsizing). This means that you probably don’t have a lot of experience with the ins and outs of real estate. On the flip side of things, REALTORS® have the experience and education to get things done within the industry. They handle contracts and the real estate process on a daily basis which means they can ensure that you are well protected.
Maybe you are a great negotiator because you do it for work, or have taken courses in it, or maybe you're just a great sweet talker....
