Typically the commission paid to sell your home is split between your agent which is also called the listing agent and the co-operating agent or buyer agent.
In today’s market the buyer agent is paid a 2.5% of the final sale price and this is pretty much accepted and practiced throughout the GTA.
Now, when it comes to seller agent or listing agent, the commission rates vary between 1% and 2.5% which means your total cost of selling your home can be 5% on the high side and 3.5% if your own agent charged you a low commission of 1%.
The fees discussed above is for a traditional real estate service provided by your local area real estate agent providing you with full listing and selling services.
There are other DIY services or mere online or MLS listing services where the effort to sell your home is a shared one and agents do part of the work and you as the home seller are responsible for some of the work.
The details of who does what can be discussed with the company you are dealing with.
