What is a Buy-Down Mortgage?
A buy-down mortgage is a loan where the interest rate is temporarily or permanently reduced through upfront payments made by the borrower or a third party.
Why Buy-Down Mortgages Matter in Real Estate
In Canadian real estate financing, buy-downs can make homeownership more affordable in the early years or help sellers/investors incentivize purchases.
Types:
- Temporary (e.g., 3-2-1 buy-down)
- Permanent (lower rate for full term)
Understanding buy-down mortgages helps buyers assess cost-benefit and long-term affordability.
Example of a Buy-Down Mortgage in Action
The builder offered a buy-down mortgage incentive, covering points to lower the buyer’s interest rate for the first three years.
