The Saskatchewan Real Estate Commission requires every licensee to put commission and material terms in writing, which protects a buyer from a verbal side deal they cannot later prove, regardless of who else is bidding on the same house.
A lawyer's review before removing conditions, generally $800 to $1,500 in fees, is the practical safeguard most buyers actually use, since it catches a problem with title, financing or the property itself before the contract becomes binding.
None of that depends on a law aimed at institutional investors; it depends on using the protections already built into a standard Saskatchewan purchase contract. Get your hand-reviewed valuation from Joel Dyck.
