Open vs. Closed Mortgages

Why Understanding Open and Closed Mortgages Matters

One of the most important decisions you'll make when selecting a mortgage is whether to choose an open or closed structure. This choice directly impacts:

How much flexibility you have to pay off your mortgage early.
What interest rate you'll pay.
Whether you can adapt your mortgage to life changes without penalties.

While both types help you achieve homeownership, they suit very different financial situations. At Optimize, we guide you through this choice, ensuring your mortgage aligns with your current needs and long-term goals.

What Is an Open Mortgage?

An open mortgage gives you the ability to:

Pay down the principal in full at any time.
Make unlimited additional payments without prepayment penalties.

This structure offers maximum flexibility, making it ideal for borrowers who:

Expect a large cash influx (such as a bonus, inheritance, or proceeds from another property sale).
Plan to sell or refinance the home in the near future.
Want the freedom to pay off the mortgage aggressively.

However, this flexibility comes at a cost. Open mortgages typically carry higher interest rates than closed mortgages. You’re paying for the option to prepay without restrictions.

What Is a Closed Mortgage?

A closed mortgage limits how much extra you can pay toward your mortgage principal each year without incurring penalties. Most closed mortgages offer:

Prepayment privileges, allowing you to pay an extra 10–20% of the original mortgage amount annually.
Lower interest rates compared to open mortgages, reflecting the lender's security in a fixed payment schedule.

Breaking a closed mortgage before the term ends (through sale, refinance, or large prepayment) usually results in penalties, which can be significant depending on rate conditions and remaining term.

At Optimize, we help you weigh these trade-offs carefully, ensuring you understand when the interest savings of a closed mortgage outweigh the value of added flexibility.

Key Differences: Flexibility vs. Interest Rate Advantage

Feature	Open Mortgage	Closed Mortgage
Prepayment Flexibility	Unlimited, any time, no penalties	Limited annual prepayment privileges
Interest Rate	Higher than closed mortgages	Lower than open mortgages
Ideal For	Short-term borrowing, uncertain timelines	Long-term borrowing, predictable planning
Early Payout Penalties	None	Penalties apply for breaking term early

This trade-off between flexibility and rate savings is at the core of choosing between open and closed mortgages.

When Each Option Makes Sense

An open mortgage is typically suitable when:

You expect to fully pay off the loan soon.
You have an uncertain timeline for staying in the property.
Flexibility outweighs cost concerns.

A closed mortgage is better when:

You plan to hold the mortgage for the full term.
You want to benefit from lower interest rates.
You’re comfortable with structured payment schedules.
