Mixed-use property mortgages in Canada: how lenders assess them

Mixed-use properties are common in Canadian cities — a storefront on the ground floor with residential units above, or a commercial unit attached to a residential dwelling. They are attractive investments because they combine two income streams. But from a mortgage perspective, they sit in an awkward middle ground that most residential agents are not equipped to handle. Here is how lenders approach them.

What counts as mixed-use

A mixed-use property contains both residential and commercial components under one title (or sometimes separate titles on the same parcel). The most common examples are a ground-floor retail or office space with one or more residential apartments above — often called a "live-work" building when the owner occupies the residential portion and runs a business below.

Mixed-use is distinct from a multi-residential property (a building with multiple residential units only) and from a commercial property with a small residential component (like an apartment above a warehouse). The defining characteristic is a meaningful combination of both use types, with income or function from each.

Residential-heavy vs. commercial-heavy: why the split matters

The biggest factor in how a mixed-use property gets financed is the split between residential and commercial area or income. Most lenders use a threshold of 50% residential as the line between residential and commercial mortgage products.

• Residential-heavy (more than 50% residential by GLA or value): Some residential lenders and credit unions will consider these properties under modified residential guidelines. CMHC insured financing is generally not available for mixed-use properties. Conventional financing at up to 75–80% LTV from certain lenders may be possible.
• Commercial-heavy (more than 50% commercial by GLA or value): These properties fall into the commercial mortgage channel. Expect commercial LTV limits — typically 65–75% from institutional commercial lenders, 60–70% from credit unions, and as low as 55–65% from private lenders.

Some lenders use income rather than square footage as the determining factor. If the commercial unit generates 60% of the property's gross income, it may be classified as commercial regardless of floor area split.

Which lenders consider mixed-use properties

Standard monoline residential lenders (First National, MCAP, RMG, etc.) typically do not accept mixed-use properties — their programs are designed for pure residential assets. Institutional commercial departments at major banks (CIBC, TD, RBC) will look at mixed-use properties above a certain loan size, typically $1 million+. Credit unions are often the most flexible for mixed-use: they can write both residential and commercial mortgages and are accustomed to local, non-standard property types.

Private lenders and MICs will fund mixed-use properties at higher rates and lower LTV — useful for purchasing or bridging, but not a long-term solution. B-lenders like Equitable Bank and Home Trust have specific programs that include properties with a small commercial component, subject to their own guidelines.

Maximum LTV on mixed-use

LTV on mixed-use properties is typically lower than on pure residential assets. The general ranges:

• Residential-leaning mixed-use (credit union, conventional): 65–75% LTV
• Commercial-leaning mixed-use (commercial lender): 60–70% LTV
• Private lender / MIC: 55–65% LTV

Mortgage default insurance (CMHC, Sagen, Canada Guaranty) is generally not available for mixed-use properties. This means all mixed-use financing is conventional — the borrower needs a larger down payment and the lender takes on the full risk.

Income blending approach

When calculating qualifying income for a mixed-use property, lenders blend the residential and commercial rental income with a vacancy allowance applied to each component separately. A commercial vacancy allowance of 10–15% may be applied, and the lender may also apply a haircut to commercial rents if lease terms are short or the tenant quality is not strong.

For owner-occupied mixed-use (the borrower lives in the residential portion and runs a business below), the borrower's personal or business income from the commercial space must be documented — typically with business financial statements or T1 Generals. Lenders want to see stable commercial occupancy history.

Appraisal challenges

Appraisals on mixed-use properties are more complex than residential appraisals and must be conducted by an appraiser with experience in commercial or mixed-use valuation. The appraiser needs to apply both income and direct comparison approaches and weigh each component appropriately. Comparable sales for mixed-use properties are genuinely scarce in many markets, which introduces more subjectivity into the value conclusion.

Lenders that require a specific appraisal firm or designate may not have an approved appraiser familiar with mixed-use assets in the subject property's market. Confirm the appraiser's experience before ordering the report — an appraisal that misclassifies the property or uses unsuitable comparables will cause delays or a lower-than-expected value conclusion.
