I bought my first and next home without a Realtor. The first house in Toronto and the next house in Calgary. So I'm proof you do not need a Realtor to buy or sell a home. My first house in Toronto was a train wreck that a Realtor would have seen coming a mile away. The second house wasn't much better. Both were very expensive mistakes. Then I became a Realtor 18 years ago and have been enjoying helping others avoid my dumb mistakes!
