Why AI Valuations (AVMs) Are Failing the 2026 GTA Market

Automated Valuation Models promise speed and efficiency in property valuation. Banks and online real estate platforms promote them as modern alternatives to traditional appraisals. But across Toronto and the GTA in 2026, these AI-powered tools are producing valuations that don’t reflect actual market conditions, and the gap between algorithmic estimates and real property values is creating financial risks for buyers, sellers, and investors.

At Innovative Property Solutions, we see the limitations of AVMs daily through our professional appraisal work across the region. The problem isn’t that artificial intelligence lacks sophistication. The issue is that 2026’s GTA real estate market has unique complexities that algorithms simply can’t capture from historical data and standard inputs.

The Bill 185 Legal Complexity AVMs Cannot Process

Bill 185 introduced appeal mechanisms that create legal uncertainties affecting property development potential across Toronto and the GTA. These appeals can freeze development rights even when zoning technically permits higher density or new construction.

The appeal process allows what planners call “global appeals,” where a single objection can create legal holds affecting multiple properties simultaneously. When this happens, property owners cannot proceed with development that should be permitted under current zoning until the appeal gets resolved through the legal system.

Resolving these appeals requires hiring legal counsel and filing detailed motions to separate individual properties from broader appeals. This process costs property owners between $15,000 and $30,000 in legal fees and can delay development timelines by months or years.

AVMs analyze zoning designations and apply value adjustments based on the development potential that zoning theoretically provides. When new zoning allows higher density, the algorithm sees increased development rights and automatically raises the property valuation accordingly.

What AVMs cannot do is check municipal appeal records to determine whether those development rights are actually accessible or legally frozen. The algorithm sees potential that exists on paper but may not be realizable in practice for extended periods.

Professional appraisers examine municipal records, understand local appeal situations, and adjust valuations to reflect the actual development potential available to property owners today rather than theoretical rights that may be inaccessible due to ongoing legal processes.

This distinction matters significantly for property values. Development potential that’s legally accessible today has genuine value. Development potential that requires expensive legal battles and years of delays before it becomes usable has substantially less value or possibly no current value at all.

The Bill 185 impact varies dramatically by location. Some neighbourhoods have clear development paths while nearby areas face extensive appeal,s creating legal gridlock. AVMs apply similar valuations across these areas based on zoning similarities, while professional appraisal accounts for the legal realities that determine which properties actually have usable development rights.

Power Capacity as the Dominant Industrial Value Driver

Industrial property valuation in the GTA has fundamentally changed due to electrical infrastructure constraints. Grid connection wait times now extend 36 to 48 months for new industrial developments requiring significant power capacity. This infrastructure bottleneck has made secured power connections more valuable than traditional location factors for many industrial uses.

Properties with existing power capacity, particularly substantial capacity of 10 megawatts or more, command significant premiums in the current market. Industrial buyers and developers prioritize power availability because, without it, properties cannot be developed or used for their intended purpose,s regardless of other advantages.

AVMs calculate industrial property values primarily using price per square foot metrics, location factors like Highway 401 proximity, and comparable sales data. These traditional inputs don’t account for power capacity because historical data from periods when power was readily available doesn’t reflect current infrastructure constraints.

The infrastructure supercycle creating these power limitations represents a recent market shift that algorithms haven’t adapted to. Historical comparable sales occurred when power wasn’t a constraining factor, so using those comparables to value properties today produces estimates that don’t reflect current buyer priorities.

Professional appraisers working in the industrial sector understand power capacity as a critical value driver. We verify power availability for properties being appraised, research grid connection timelines, and apply appropriate value adjustments based on whether properties have secured capacity versus properties waiting years for connections.

The value difference isn’t subtle. Industrial properties with secured power capacity sell at premiums that can reach millions of dollars compared to otherwise similar properties without power commitments. This premium reflects real market behaviour and buyer willingness to pay substantially more for properties they can actually use and develop without multi-year delays.

AVMs analyzing these properties might show valuation differences of 5 to 10 percent based on minor location variations. Professional appraisal reveals value differences of 20 to 40 percent or more, driven entirely by power capacity factors that algorithms don’t measure.

Distinguishing Turnkey Quality From Cosmetic Updates

Property condition assessments require physical inspection and professional judgment to evaluate renovation quality, identify deferred maintenance, and determine whether properties are genuinely move-in ready or require substantial additional investment.

The 2026 market shows significant premiums for truly turnkey properties where buyers can take possession without needing further work. With trade costs at record levels and contractor availability limited, buyers pay substantial premiums to avoid post-purchase renovation expenses and delays.

AVMs identify renovated properties through listing descriptions and apply value adjustments based on renovation mentions. But not all renovations provide equal value. Cosmetic updates that make properties look appealing in photos may hide underlying issues requiring expensive repairs.

Electrical systems, plumbing, HVAC equipment, and structural elements aren’t visible in listing photos or describable in MLS data that AVMs analyze. These systems significantly affect property values and buyer costs but require physical inspection to evaluate properly.

Professional appraisers conduct property inspections that identify renovation quality, evaluate building systems, and distinguish between genuine turnkey condition versus cosmetic improvements that don’t address fundamental property needs.

This distinction affects valuations substantially. A property that looks renovated but needs $50,000 in hidden repairs should be valued $50,000 less than a property in genuine turnkey condition, even if both appear similar in photos and listing descriptions.

AVMs applying standard renovation adjustments don’t account for these quality differences because they lack inspection capabilities and can’t evaluate underlying conditions that determine true property status.

Buyers relying on AVM estimates for properties described as renovated may significantly overpay if the actual condition requires additional investment that the algorithm didn’t account for in its valuation.

Vacant Home Tax Risk Assessment

Toronto’s Vacant Home Tax at 3% of the current value assessment creates significant financial exposure for properties that the city determines were vacant during the applicable period. On a million-dollar property, this tax amounts to $30,000, creating substantial liability that affects property values and buyer decisions.

Exemptions exist for specific situations, including properties vacant due to renovations, but these exemptions require proper documentation, including active building permits covering the vacancy period.

Properties claiming renovation exemptions without proper permit documentation face audit risk that can result in full tax assessment plus penalties. This risk creates hidden liabilities that affect property values but aren’t visible to potential buyers or algorithms analyzing property data.

AVMs have no mechanism to assess Vacant Home Tax exposure or verify exemption claim validity. They value properties based on physical characteristics and comparable sales without considering potential tax liabilities that could represent 3% of property value.

Professional appraisers check municipal permit records, evaluate Vacant Home Tax applicability, and identify potential liabilities that affect property values. This due diligence reveals risks that AVMs cannot detect because they lack access to permit databases and the analytical framework to assess tax exposure.

The impact on valuation is direct. A property with a verified VHT exemption is worth $30,000 more than an identical property with questionable exemption claims that may result in tax assessment.

This $30,000 difference represents real financial exposure that buyers should understand before purchase, but that AVMs don’t incorporate into their valuations.

Income Valuation of Below-Grade Space

Standard residential valuation formulas treat basement space as worth 50% to 70% of main floor square footage. This approach works for typical basements used for storage or recreation, but fails to capture the value of legal secondary suites that generate rental income.

A legal basement apartment in Toronto generates monthly rent between $1,800 and $2,500, depending on size, location, and finishes. This represents an annual gross income of $21,600 to $30,000 from space that square footage formulas might value at $40,000 to $60,000.

Income-producing properties require valuation approaches that account for cash flow generation, not just physical square footage. The income approach capitalizes rental income to determine the value that the income stream provides to property owners.

Using income capitalization methodology, a basement suite generating $24,000 annually justifies valuations of $240,000 or more, substantially exceeding the value that square footage formulas suggest.

Garden suites present similar valuation challenges. These structures can generate $2,000 to $4,500 monthly in rental income, representing annual income of $24,000 to $54,000 that traditional square footage valuation doesn’t properly capture.

AVMs using residential valuation models add incremental value for additional living space, but don’t properly account for income generation that provides genuine financial value to property owners and investors.

Professional appraisers apply income approaches for properties with legal rental units, calculating values based on actual income generation rather than just physical space additions.

The valuation difference between square footage approaches and income approaches can exceed $150,000 for properties with substantial legal rental income. This gap represents real value that AVMs systematically underestimate.

Market Psychology in Sideways Price Environments

AVMs function most effectively when markets show clear directional trends, either upward or downward. Historical sales data combined with trend analysis produces reasonable projections when momentum continues in established directions.

The 2026 GTA market moves sideways with significant volatility rather than trending clearly in either direction. This creates challenges for algorithms designed to identify and project momentum.

Current market conditions show extended marketing periods with properties requiring an average of 24 showings before securing firm offers. This represents buyer caution and selectivity that affects realistic pricing expectations.

Properties sitting on the market for extended periods often require price reductions before generating acceptable offers. The gap between initial list prices and final sale prices frequently reaches $50,000 to $150,000 as sellers adjust expectations to match buyer willingness to pay.

AVMs analyze completed sales to establish property values, but don’t account for failed listings, withdrawn properties, or the extensive price reductions required to achieve sales in the current market.

Professional appraisers track not just successful sales but also market failures, days on market statistics, and price reduction patterns that reveal current buyer behaviour and realistic pricing levels.

This market intelligence comes from continuous engagement with active listings, buyer feedback, and transaction patterns that show how properties actually move through the market rather than just final sale prices.

Understanding current market psychology and buyer behaviour affects valuation conclusions substantially. Properties that AVMs value based on historical comparable sales may be overvalued by $50,000 to $100,000 or more compared to what buyers will actually pay in today’s cautious market environment.
