Short answer
CMHC mortgage insurance is a type of mortgage default insurance that protects the lender if a borrower defaults. It is commonly required when a buyer has less than 20% down on an eligible home purchase. The premium can often be added to the mortgage, but that increases the mortgage balance and total borrowing cost.
Key takeaways
- Mortgage default insurance protects the lender, not the borrower.
- It is commonly required when the down payment is below 20%.
- Premiums can increase the mortgage balance and total interest paid.
- Insured mortgages can still have competitive rates because lender risk is reduced.
Quick answer
CMHC mortgage insurance, along with other mortgage default insurance providers, helps lenders manage risk when a buyer has a smaller down payment. The borrower pays the premium, but the insurance protects the lender if the borrower defaults.
When mortgage insurance is commonly required
Mortgage default insurance is commonly required when a buyer puts less than 20% down on an eligible purchase. The home must meet program and lender criteria. Higher-priced homes, rental properties, unusual properties, and some borrower situations may have different requirements.
Why insured rates can be competitive
Some insured mortgages may receive competitive rates because the lender has default-insurance protection. That does not mean insurance is free; the borrower still pays the premium. The right choice depends on cash available, affordability, and long-term plans.
What to try next
Compare a 10% down scenario with a 20% down scenario. Look at the payment, LTV, cash needed, insurance premium impact, and how much cash remains after closing.
Frequently asked questions
Does CMHC insurance protect the home buyer?
No. Mortgage default insurance protects the lender if the borrower defaults. It does not replace life, disability, job-loss, or home insurance.
Can the insurance premium be added to the mortgage?
Often yes, but adding it to the mortgage increases the borrowed amount and can increase total interest paid.
