CMHC rules and eligibility requirements can change. This guide reflects the general rules as of publication. Always confirm current eligibility and requirements directly with CMHC or your mortgage broker before making financing decisions.

What CMHC mortgage insurance is

CMHC, which stands for Canada Mortgage and Housing Corporation, is a federal Crown corporation that provides mortgage loan insurance to lenders. When a borrower puts down less than 20% on a home purchase, the lender requires mortgage insurance to protect against default. CMHC is the largest provider of this insurance in Canada, alongside private insurers Sagen and Canada Guaranty.

Mortgage insurance is sometimes confused with mortgage life insurance or home insurance. It is none of those things. It is insurance that the lender purchases against the risk of borrower default, and the cost is passed to the borrower as a premium added to the mortgage balance. The borrower pays for insurance that protects the lender.

The key benefit to borrowers is that mortgage insurance allows them to purchase a home with as little as 5% down on a primary residence. Without insurance, lenders require a minimum of 20% down. This is why first-time homebuyers can access homes with a small down payment while investment property buyers cannot.

The core rule for rental property investors

CMHC mortgage insurance is not available for non-owner-occupied investment properties. If you are purchasing a property you do not plan to live in, you must put down at least 20% of the purchase price. There is no insured option and no exception to this rule for investment properties.

This is one of the most important facts for anyone entering rental property investing in Canada. It means:

Not available for investors

Properties you will not occupy as your primary residence

Properties purchased solely to rent out

Second homes used as investment properties

Any non-owner-occupied residential property

May be available with conditions

Properties of 1 to 4 units where you occupy one unit as your primary residence

Subject to specific down payment rules based on number of units

Subject to rental income treatment rules for qualification

Confirm current eligibility with CMHC or your broker

The practical consequence is straightforward. To buy a $600,000 rental property in Canada, you need a minimum of $120,000 in cash as a down payment. There is no way around this for a property you will not occupy.

The owner-occupied rental exception

There is one situation where CMHC insurance may be available on a property that generates rental income: when you purchase a small residential property of one to four units and occupy one unit as your principal residence. This is sometimes called a duplex, triplex or fourplex strategy.

In this scenario, you are the owner-occupant of the property, and the rental units generate income that helps you qualify for the mortgage. CMHC treats the property as an owner-occupied home rather than an investment property for insurance purposes.

Property typeOwner-occupied requirementMinimum down paymentCMHC available
1-unit (single family home)Must be primary residence5% on first $500,000, 10% aboveYes
2-unit (duplex)Must occupy one unit5% on first $500,000, 10% aboveYes
3-unit (triplex)Must occupy one unit10%Yes
4-unit (fourplex)Must occupy one unit10%Yes
5+ unitsN/AConventional financingNo
Non-owner-occupied (any size)Not applicable20% minimumNo

The owner-occupied multi-unit strategy is a legitimate and commonly used entry point for new investors. Buying a duplex, living in one unit and renting the other reduces your personal housing cost while building equity and generating rental income. The rental income from the other unit can often be counted toward your mortgage qualification.

If you use this strategy and later move out of the property, your occupancy status changes and your mortgage and insurance terms may be affected. Discuss the implications with your mortgage broker and lender before making any changes to your occupancy.

CMHC insurance premium rates

When CMHC insurance does apply, the premium is calculated as a percentage of the mortgage amount and is added to the total mortgage balance. You then pay interest on the premium over the life of the mortgage. The premium is not an upfront cash cost at closing, though provincial premium taxes may apply in some provinces and are paid at closing.

Down payment percentageCMHC premium (% of mortgage)
5% to 9.99%4.00%
10% to 14.99%3.10%
15% to 19.99%2.80%
20% or moreNo insurance required

As an investor with a mandatory 20% down payment, you will not pay a CMHC premium. This is actually a benefit of the investment property rules: you avoid adding a premium to your mortgage balance. The tradeoff is the larger upfront cash requirement.

For owner-occupied multi-unit buyers using the exception above, the premium applies to the insured portion of the mortgage and adds to the total borrowing cost. Factor this into your analysis when comparing a duplex strategy with a conventional investment property purchase.

How the 20% rule affects your investment analysis

The 20% down payment requirement has several practical effects on how you analyze and plan a rental property purchase.

Your cash requirement is larger than many buyers expect

On a $700,000 property, 20% down is $140,000 before closing costs. Add land transfer tax, legal fees, inspection and title insurance and the total cash required to close is often $155,000 to $175,000 depending on the province. Plan for the full acquisition cost, not just the down payment percentage.

Your mortgage balance is smaller, which helps cash flow

Because you are putting more down, your mortgage balance is lower than it would be for an equivalent owner-occupied purchase with 5% down. This reduces your monthly mortgage payment and improves cash flow compared to a scenario where you could have borrowed more. Run both scenarios in the calculator to see the difference.

The stress test still applies

Even with 20% down and no CMHC insurance required, the federal mortgage stress test applies to all investment property mortgages from federally regulated lenders. You must qualify at the higher of your actual rate plus 2% or the OSFI minimum qualifying rate. The stress test reduces the maximum mortgage you can access regardless of your down payment size. See the mortgage stress test guide for a full explanation.

Rental income can help you qualify

Most lenders will count a portion of the expected rental income from the investment property toward your gross income for qualification purposes. The percentage varies by lender and typically ranges from 50 to 80% of gross expected rent. A mortgage broker who works with investors will know which lenders apply the most favorable rental income treatment for your situation.

Common questions about CMHC and rental properties

CMHC mortgage insurance is not available for non-owner-occupied investment properties. If you are purchasing a property you do not intend to live in, you must put down at least 20% of the purchase price. There is no insured option and no exception for investment properties. If you plan to live in one unit of a 1 to 4 unit property, different rules apply and CMHC insurance may be available.
The minimum down payment for a non-owner-occupied rental property is 20% of the purchase price, regardless of the price. Because CMHC insurance is not available for investment properties, there is no way to access a lower down payment. On a $500,000 property that is $100,000 before closing costs. On a $800,000 property it is $160,000. Plan for the full acquisition cost including land transfer tax, legal fees and other closing costs.
If you purchase a 1 to 4 unit property and occupy one unit as your principal residence, CMHC insurance may be available. For 1 to 2 unit properties, the minimum down payment is 5% on the first $500,000 and 10% above that. For 3 to 4 unit properties, the minimum is 10%. This is a common strategy for investors who want to get into the rental market with a smaller down payment while also reducing their personal housing costs. Confirm current eligibility and rules with your mortgage broker or directly with CMHC before proceeding.
Yes. The federal mortgage stress test applies to all investment property mortgages from federally regulated lenders, regardless of down payment size. Even with 20% down and no CMHC insurance required, you must qualify at the higher of your actual mortgage rate plus 2% or the minimum qualifying rate set by OSFI. This reduces the maximum mortgage amount you can access compared to what your actual payment would suggest. See the mortgage stress test guide for a full explanation of how this works in practice.
No. Canada has two private mortgage insurers in addition to CMHC: Sagen (formerly Genworth Canada) and Canada Guaranty. All three insurers provide mortgage insurance to lenders and the rules for investment properties are essentially the same across all three. CMHC is the largest and most widely known, which is why the term CMHC is often used colloquially to refer to mortgage insurance generally, even when a private insurer is actually involved.
Misrepresenting your intended occupancy to obtain an insured mortgage at a lower down payment is mortgage fraud. This is a serious offence that can result in the lender demanding immediate repayment of the full mortgage balance, criminal charges, and civil liability. Lenders and CMHC have processes for identifying fraud, including monitoring rental listings and CRA reporting. The consequences are severe and not worth the risk. If you plan to rent out the property, use conventional financing with 20% down.
