Those closing costs cover legal fees, adjustments and commission together rather than any cash-specific charge, and a lawyer completes every Saskatoon transaction, cash or financed, through the same title process with Information Services Corporation.
The one real advantage a cash buyer has here is speed and certainty, since removing a financing condition can make an offer more attractive to a seller in a market with 1.63 months of supply, not a tax saving that does not exist to begin with.
If speed and certainty matter to your specific purchase, that is worth discussing directly. Get your hand-reviewed valuation from Joel Dyck.
