North America has literally 100's of 1000's of real estate agents spread through the states in the US and the provinces of Canada. How do you know when you are working with a good agent, in short you don't. you rely on word of mouth, whether the agent is local, do they seem to have local expertise etc.
We allow you our visitors to tell us we should list an agent, we then list their details and allow you to make comments and review them. Hopefully that gives you our visitors an insight into who is out there and how they can help you.
Real estate is a big market and one of the biggest purchases you will every make, so having a great agent is the start of taking care of your investment.
