What is a Blended Mortgage?
A blended mortgage combines two different mortgage loans or interest rates into one, resulting in a new single loan with a blended interest rate.
Why Blended Mortgages Matter in Real Estate
In Canadian mortgage financing, blended mortgages help borrowers modify financing without full refinancing, often during porting or top-up situations.
Key features:
- Mixes existing loan with new funds
- Creates an average (blended) interest rate
- May avoid penalties for breaking existing mortgage
Understanding blended mortgages helps homeowners manage changing financing needs.
Example of a Blended Mortgage in Action
