Portable mortgage or assumption: moving without breaking your loan

Keeping your rate and terms on the new property, or handing your loan to the buyer: what each option requires, and how an insured loan is treated.

The short answer

The two options

Portable mortgageAssumption (takeover)
Who keeps the loanYou, on the new propertyThe buyer, on the property you sell
What you keepRate, term, conditionsNothing: you are released if the lender agrees
What the lender checksIncome, credit and the new propertyThe buyer’s income and credit
PenaltyAvoided if the contract rules are metAvoided if the buyer takes over the loan

The contract says whether the loan is portable, within what delay and under what conditions. A lender may refuse if the new property does not meet its rules.

When the loan is CMHC-insured

An insured loan can be transferred to a new property. Three cases:

  • Simple transfer: the balance, remaining amortization and loan-to-value do not rise. No new premium.
  • Transfer with a larger loan: the premium is charged on the new funds at a separate rate. For example, 6.25% for a 85.01% to 90% ratio, instead of 3.10% on the whole loan.
  • Transfer with a higher ratio, same amount: amortization stays at the remaining term.

Main conditions: the application must be received within 6 months of closing on the first property, the loan must be in good standing, the new property must have the same use, and at least one borrower must be on both loans.

Frequently asked questions

Can I port my loan if I buy before selling?

It depends on the contract. CMHC requires the first property to be sold for an insurance transfer; a bridge loan can cover the gap.

Does porting avoid the penalty?

If the contract allows it and you meet its conditions, yes. Otherwise breaking the loan triggers the penalty.

What if the new price is higher?

You add funds, often at today’s rate, and the added portion follows its own terms.
