Insured, Insurable or Uninsured: Why Your Mortgage Rate Depends on It

The same lender can quote three different rates on the same day. Which one you get depends on whether your mortgage is insured, insurable or uninsured.

By Tim Lacroix, Mortgage Broker · Lacroix Mortgage Group · Updated September 26, 2026

Short answer: Lenders price mortgages in three groups. Insured (less than 20% down, you pay the insurance premium) usually gets the lowest rate. Insurable (20% or more down, but it still meets the insurance rules) is close behind, and you pay no premium. Uninsured (refinances, rentals, 30 year amortizations with 20% down, homes $1 million and up with 20% down) has the highest rates. The rates we post are insured rates.

Why it matters

Mortgage default insurance protects the lender, not you, if a borrower stops paying. When a mortgage is insured, the lender’s risk is lower and its funding is cheaper, so the rate is lower. That’s why a buyer with 5% down can sometimes get a better rate than a buyer with 25% down.

High ratio vs conventional

These words describe your down payment:

  • High ratio: less than 20% down. Insurance is required, so it’s always insured.
  • Conventional: 20% or more down. It’s insurable if it fits the rules above, and uninsured if it doesn’t.

At renewal

If your mortgage was insured when you bought, it stays insured, and you can usually switch lenders at renewal and keep insured pricing. That’s often worth more than people expect. If you’re adding money or refinancing, the mortgage becomes uninsured, so the rate is usually higher. Sometimes a home equity line of credit beside your existing mortgage keeps the better rate on the main balance.

Examples

  • First time buyer, $450,000 condo, 5% down: insured. Pays a CMHC premium, gets the lowest rates.
  • Move up buyer, $700,000 home, 25% down, 25 year amortization: insurable. No premium, slightly higher rate than insured.
  • Same buyer, but wants a 30 year amortization: uninsured. Lower payment, higher rate.
  • Homeowner refinancing to consolidate debt: uninsured. Worth comparing against a line of credit first.

Frequently asked questions

What does an insured mortgage rate mean?

It's the rate for a mortgage with less than 20% down, where default insurance from CMHC, Sagen or Canada Guaranty is required. The borrower pays the insurance premium. Because the lender's risk is covered, insured mortgages usually get the lowest rates.

What is an insurable mortgage?

A mortgage with 20% or more down that still meets the insurance rules: a purchase or straight switch, owner occupied, a price under $1 million and an amortization of 25 years or less. The lender can insure it in bulk at its own cost, so you pay no premium and still get a lower rate than uninsured.

What makes a mortgage uninsured?

Anything outside the insurance rules: refinances, amortizations over 25 years with 20% or more down, purchase prices of $1 million or more with 20% or more down, and rental properties. These carry the highest rates because the lender keeps all the risk.

What is the difference between high ratio and conventional?

High ratio means less than 20% down, so insurance is required. Conventional means 20% or more down. A conventional mortgage can be insurable or uninsured, depending on the rules above.
