Commercial Property Valuation: How Much Is Your Property Really Worth?

Commercial property valuation in Ontario is done by comparing three lenses on the same asset: what income the property produces (the income approach), what similar properties have sold for (the direct comparison approach), and what it would cost to replace (the cost approach). Professionals choose and weight these methods depending on the property type and the purpose of the valuation, and the result is a supported range rather than a single true number. This guide explains how each method works, who provides which kind of valuation, and how to judge whether a number you are given deserves your trust. For a hands-on estimate, see our owner’s valuation worksheet.

The Income Approach

For rental property, the income approach usually carries the most weight. Two techniques are common:

• Direct capitalization: value equals stabilized net operating income divided by a capitalization rate. It works best for stable properties with predictable income.
• Discounted cash flow (DCF): projects income and expenses over a holding period, including lease rollovers, capital spending and a resale value, and discounts them at a required rate of return. It suits properties with significant lease-up, redevelopment or changing income.

Both depend on the quality of the inputs: verified rent rolls, normalized expenses and cap or discount rates supported by market evidence. See how to calculate NOI and what a cap rate is.

The Direct Comparison Approach

This method compares the subject property with recent sales of similar properties and adjusts for differences such as size, age, condition, location, lease profile and zoning. It is especially important for owner-occupied buildings, vacant land and smaller properties where buyers think in price per square foot, per acre or per suite. Reliability depends on the availability of good comparables, and on whether the adjustments are reasoned rather than arbitrary. A comparable from a different submarket or a different time can mislead unless it is adjusted with care.

The Cost Approach

The cost approach estimates land value plus the cost to construct a replacement building, less depreciation. It is most often used for new or special-purpose properties, for insurance purposes and as a cross-check for other methods. Buyers of income properties rarely pay strictly by cost, but the replacement cost can indicate a ceiling on what buyers will pay for an existing building, or explain why new development is or is not viable.

Other Valuation Techniques

• Residual land value: for development sites, estimates what a developer can pay for land after subtracting construction costs, fees, financing and required profit from the expected value of the finished project.
• Gross rent multiplier and price per suite: quick benchmarks, particularly for apartment buildings, that should be cross-checked against NOI-based value.
• Highest and best use analysis: asks what legal, physical and financially feasible use would produce the highest value, which can differ from the current use.

Who Provides Which Type of Valuation?

• Accredited appraisers: in Canada, commercial appraisers commonly hold the AACI designation from the Appraisal Institute of Canada. A formal appraisal report follows professional standards and is what lenders, courts and tax authorities generally rely on.
• Brokers: provide opinions of value or broker opinions of value based on market activity and buyer feedback. These are useful for pricing decisions but are not appraisals.
• Lenders: commission their own appraisals to size a loan, which may be more conservative than a sale price.
• MPAC: assesses property for taxation. Its 2026 assessments still reflect January 1, 2016 values, so they are not a substitute for a current market valuation.

Choosing the Method That Fits the Purpose

The purpose changes the answer. A sale price aims at probable market value, a lender wants a conservative value, an insurer wants replacement cost, an estate may require a value as of a specific date, and a tax dispute requires a prescribed method. Tell the valuator what the number will be used for, and ask which approaches they will apply and why.

How to Judge a Valuation

• Are income and expense figures traceable to leases and statements?
• Is the cap rate supported by identified comparable sales?
• Are adjustments explained rather than asserted?
• Does the report state its assumptions and limiting conditions?
• Do the different approaches reconcile, or is any large gap explained?

Frequently Asked Questions

Which valuation method is the most accurate?

None is universally best. The income approach dominates for rental property, comparison for land and owner-occupied buildings, and the best valuations reconcile more than one method.

Is a broker’s opinion of value the same as an appraisal?

No. An appraisal follows professional standards and is prepared by an accredited appraiser, while a broker’s opinion is a market-based estimate for pricing.

Why do lenders’ values differ from sale prices?

Lenders tend to be conservative, use different assumptions and may value for a different purpose.

How often should a property be revalued?

When leases, market conditions or your plans change, and before any sale, refinancing or restructuring.

Conclusion

Valuing commercial property means applying the income, direct comparison and cost approaches as appropriate and reconciling the results into a supported range. Match the method to the purpose, insist on traceable inputs and treat any single figure with caution. CapRate.ca provides property-specific valuations for owners in the GTA and Southern Ontario.
