The simple formula
Possible term savings minus costs and effort equals the real switch value. A better advertised rate is not enough by itself.
Costs to ask about
- Discharge or administration costs from the current lender.
- Setup, transfer, assignment, or registration costs.
- Appraisal or property valuation requirements.
- Legal, title, or notary work.
- Extra complexity from a HELOC, collateral charge, refinance request, or linked secured product.
When switching may be worth comparing
Switching is more likely worth comparing when the rate gap is meaningful, the mortgage balance is large, the deadline gives enough time, and the new lender confirms which costs may be covered.

Frequently asked questions
What costs can apply when switching lenders at renewal?
Possible costs can include discharge, setup, registration, appraisal, legal, notary, transfer, assignment, and administration costs. Exact costs depend on the lender, province, and mortgage structure.
Is switching lenders free at renewal?
Not always. Some switches may be low-cost and some lenders may cover selected costs, but borrowers should ask directly before relying on that assumption.
How do I know whether switching is worth it?
Estimate the possible rate savings over the term, then compare that against likely costs, effort, timing, and mortgage complexity.
Does FairRate arrange switches?
No. FairRate provides independent educational rate context. It is not a lender or broker and does not arrange mortgages.
