What Do Appraisers Look For? How Home Value Is Determined
Homeowners often assume an appraisal is a walk-through and a gut feeling. In practice, a designated appraiser follows a structured method set out in the Canadian Uniform Standards of Professional Appraisal Practice (CUSPAP), weighing evidence drawn from the market rather than opinion. Here is what actually goes into the number.
The three approaches to value
Every appraisal in Canada rests on up to three recognized approaches. The direct comparison approach analyses recent sales of similar properties and adjusts them to the subject; it is the primary method for most houses, condominiums and townhouses. The cost approach estimates what it would cost to rebuild the improvements today, subtracts depreciation and adds the land value as if vacant; it suits new construction, unusual properties and insurance replacement cost work. The income approach converts the rent a property can reasonably produce into a value figure, and carries most commercial, industrial and multi-residential assignments.
An appraiser does not apply all three by default. CUSPAP requires each to be considered, and the report explains which were used and why the others were excluded. A forty-year-old bungalow with a dozen recent sales on nearby streets rarely needs a cost approach; a purpose-built rental building with no close comparables usually needs the income approach to carry the conclusion.
How comparable sales are chosen and adjusted
Comparables are not simply the nearest recent sales. The appraiser looks for arm's-length transactions of properties that competed with the subject for the same buyer — similar neighbourhood, style, size, lot, age and condition — and that closed recently enough to reflect the current market. Active and expired listings can support conclusions about market direction, but closed sales carry the weight.
Adjustments are then made line by line. A comparable with an extra bathroom, a finished basement, a double garage or two hundred more square feet is adjusted downward toward the subject; one on a busier street or a smaller lot is adjusted upward. The adjustment is not the cost of the feature — it is what the market has paid for it, often considerably less. If prices moved between a comparable's sale date and the effective date of the appraisal, a time adjustment applies too.
Location, lot, size, age, condition and permitted use
Location does the heaviest lifting, at a fine grain: a school catchment, a transit line, a quiet crescent versus an arterial road, a ravine or waterfront exposure, and proximity to commercial or industrial uses can separate two otherwise identical houses. Lot size, shape, frontage, servicing and topography follow closely, and dominate for acreages and vacant land, where the parcel is the asset.
Inside the improvements, appraisers measure gross living area to a consistent standard, count above-grade bedrooms and bathrooms separately from below-grade space, and record effective age rather than chronological age alone — a 1965 home with newer windows, roof, furnace and wiring may have a much younger effective age. Construction quality, functional layout and deferred maintenance are recorded too.
Permitted use is the legal envelope around all of it. Zoning, official plan designation, legal non-conforming status, a registered secondary suite versus an unregistered one, easements and rights-of-way determine what an owner may legally do with the property. Appraisers value the use that is legally permissible, physically possible and financially feasible — not what a seller hopes will be allowed someday.
What does not move the value
Several things clients expect to count usually do not. What you paid, what you still owe, what you spent on renovations, and what you need to clear a debt are not evidence of market value. Neither is a provincial assessment notice, which is prepared for taxation on a different effective date and methodology.
Personal circumstances — a separation, a job transfer, an urgent closing date — cannot influence the conclusion either. CUSPAP requires impartiality, and a designated appraiser may not accept an assignment conditioned on reaching a predetermined value. Staging, furniture and decor are excluded, as are chattels that are not part of the real property. Nor does every renovation return its cost: a high-end kitchen in a modest neighbourhood usually recovers only part of the outlay, because value is bounded by what buyers in that segment will pay.
Why CUSPAP reports hold up with lenders and courts
Appraisers holding a designation from the Appraisal Institute of Canada — AACI, or CRA, which here means Canadian Residential Appraiser and not the Canada Revenue Agency — must comply with CUSPAP. The standards govern scope of work, disclosure of assumptions and limiting conditions, retention of a working file supporting the conclusion, and independence from the outcome.
That structure is why a CUSPAP-compliant report is generally accepted by lenders for mortgage financing and refinancing, relied on by courts in matrimonial and estate matters, and used wherever a supportable value must be documented — including capital gains matters involving the Canada Revenue Agency, the federal tax authority that shares those initials. A signed report also carries professional accountability behind it, which an automated online estimate does not.
Get a value you can rely on
The right appraiser depends on the property and the purpose. A house, condominium or small multiplex is often well served by a CRA-designated appraiser (Canadian Residential Appraiser), while commercial, industrial, agricultural, machinery and equipment, or otherwise complex assignments call for an AACI. Appraisal Canada does not carry out inspections itself; it matches you with an appropriately designated AIC member for your property type, location and intended use, in English, French or Spanish.
