Ask which brokerage they are licensed under, since the Saskatchewan Real Estate Commission requires every agent to trade through a supervising brokerage, such as Real Broker SK Ltd., rather than independently, and that brokerage carries responsibility if something goes wrong.
Get the commission and services in writing before signing anything, since a verbal promise about marketing or price is not enforceable, and the written agreement is also where a $800 to $1,500 estimate for legal closing costs is worth asking the agent to walk through.
None of this takes more than a phone call and a few questions, and it is far easier to check before signing than to sort out afterward. Get your hand-reviewed valuation from Joel Dyck.
