Making the Decision

Choose Collateral If:

Situation Why
Plan to stay with lender long-term Switching cost doesn’t matter
Want easy access to equity Avoid re-registration costs
Will use readvanceable features Valuable flexibility
TD/Tangerine offers best rate May be worth it

Choose Conventional If:

Situation Why
Like to shop rates at renewal Easy transfer
May need second mortgage Keep options open
Value flexibility Not locked in
Uncertain about staying with lender Lower switching costs

What to Do If You Have a Collateral Mortgage

At Renewal

Strategy Action
Negotiate hard Lender knows switching costs
Get competing quotes Show them to your lender
Calculate break-even Is switching worth the cost?
Consider staying If rate is competitive

Break-Even Calculation

Factor Amount
Switching cost $1,500
Mortgage amount $300,000
Rate difference needed 0.1% annually = $300
Years to break even 5 years

If you can save more than 0.1%, switching may be worth it.
