The Calgary MLS® listings should be considered as your bread and butter when you are trying to sell a home. Between your real estate agent and these listings you'll be able to reach the public that is actually looking for a home to buy. It is the number one way to connect buyers to sellers and if you're not using this service you won't see a sale as quickly as you would if you were using it.
Thousands of people across the country and in Calgary are flocking to the Internet in order to browse through the homes on different websites. If you go to any real estate agent's site you'll see the MLS® listings there. It is the main advertising path that agents use to show people everything that's available.
