If you’re buying a home in Red Deer, there’s a good chance you’ll hear the term mortgage default insurance pretty early on. 

A lot of people hear “insurance” and assume it’s just one more fee, or something that mostly helps the bank and not them. Technically, yes, it protects the lender. But honestly, it also makes homeownership possible for a lot of buyers who would otherwise waiting years to save a huge down payment.

I talk about this with clients all the time, and once you strip away the jargon, it’s actually pretty straightforward.

What exactly is mortgage default insurance?

Mortgage default insurance is insurance on the mortgage when you buy with less than 20% down. You’ll hear people call it CMHC insurance, but CMHC is just one provider. Sagen and Canada Guaranty offer it too.

The big thing to know is it protects the lender if a borrower can’t make their mortgage payments.

In Canada, if your down payment is under 20%, your mortgage generally has to be insured. That’s because the lender is taking on more risk when you’re borrowing more than 80% of the home’s value. The insurance helps cover that risk, which is what allows lenders to offer those lower down payment options in the first place. 

Why should you be glad it exists?

Fair question. If it protects the lender, why should you care?

Because without it, a lot of buyers would need 20% down. And for most people, that’s a huge number.

Here’s a simple example:

If you’re looking at a $450,000 home, a 20% down payment is $90,000.

If you’re buying with 5% down, that’s $22,500.

That gap is massive. For a lot of buyers, it’s the difference between buying now and spending years trying to catch up while rent keeps going out the door and home prices keep moving.

So even though the insurance is there for the lender, it also opens the door for you much sooner.

How does the down payment scale work?

For homes up to $1.5 million, here’s the general structure:

  • Homes under $500,000 - a minimum 5% down
  • Homes between $500,000 and $1,499,999 - 5% on the first $500,000, then 10% on the portion above $500,000
  • Homes $1.5 million and up - mortgage default insurance isn’t available, so you need at least 20% down

That’s the basic framework most buyers are working within.

 

How much does the insurance cost?

The premium is based on how much you’re borrowing compared to the value of the home. In other words, your loan-to-value ratio.

In general, the smaller your down payment, the higher the premium.

Here’s a rough guide:

  • Down payment under 10% with an LTV of 90.01% to 95%: premium is around 4.0%
  • Down payment from 10% to 14.99% with an LTV of 85.01% to 90%: premium is around 3.1%
  • Down payment from 15% to 19.99% with an LTV of 80.01% to 85%: premium is around 2.8%

 

Most of the time, you don’t pay that premium out of pocket on closing day. It gets added to your mortgage amount and paid off over time through your regular mortgage payments.

Who qualifies for an insured mortgage?

There are some basic qualification rules, and while every file is a little different, lenders and insurers are usually looking at the same main things.

Credit score: usually at least one borrower needs a score of 600 or higher.

Debt ratios: lenders look at your GDS and TDS to make sure the payment fits your income.

Very generally, those caps are around 39% and 44%.

Owner-occupied property: insured mortgages are generally for homes you’re going to live in, not straight investment properties.

This is where I can really help. I can look at the full picture, not just one piece of it, and help you figure out what’s realistic based on your income, credit, down payment, and goals.
