That written buyer's agency agreement is where the real answer lives for your specific purchase, since it spells out whether your agent is paid entirely from the seller's side, whether a portion could fall to you in an unusual transaction, and what happens if the deal falls through partway.
Where cost can genuinely shift to you is a private sale with no cooperating brokerage, a for-sale-by-owner property, or a purchase where the seller's offered compensation does not match what your written agreement specifies, all situations worth flagging with your agent before you write an offer.
Read your buyer's agency agreement line by line rather than assuming the standard arrangement applies to every property you might buy near the Saskatoon benchmark of $444,700. Get your hand-reviewed valuation from Joel Dyck.
