Which Mortgage Features Actually Protect You? - Flexibility Fit Tool
A mortgage isn't just a rate - it's a set of rules you'll live with.
This tool provides estimates for informational purposes only. Actual rates and results depend on your specific situation. Rates last updated 2026-04-06. Rates are subject to change at any time.
Rate Isn’t Everything - Flexibility Can Save You More
Most people shop for the lowest rate. But the cheapest mortgage on paper can become the most expensive one if your life changes - and it usually does.
Portability Saves You Thousands
If you sell and buy a new home, a portable mortgage lets you transfer your existing rate. Without portability, you break your mortgage and pay the penalty - which at a Big 6 bank could be $10,000-$30,000+.
Penalty Structure Is the Hidden Cost
Monoline lenders (accessed through brokers) typically charge 3-month interest as a penalty. Big 6 banks charge the higher of IRD or 3-month interest, using inflated posted rates. On a $400K mortgage, this difference can be $15,000+.
The Bottom Line
A mortgage that’s 0.05% lower in rate but has a $20,000 penalty if you move isn’t a good deal. This tool helps you see what actually matters based on your life - not just your spreadsheet.
