teck21 is right. Buyers do not have to pay commission for the purchase of a private
property. Sellers usually pay a 2% commission to the agent when they engage them to sell their property.
Since there is no commission payable on your part if you engage an agent, your agent will share the commission with the seller's agent - market practice! Your agent will also assist in documents such as the offer to purchase and option to purchase.
There is no issue for you to engage the seller's agent direct, except that this agent may have conflict of interest, serving both buyer and seller at the same time. In fact, by next year, there will be a new regulation that 1 agent cannot serve both the buyer and seller.
All the best in your search!
