Most Toronto buyers treat a home inspection as a formality. Michael Prior treats it as one of the most important risk management tools in the entire transaction. As founder of The Prior Group at Revel Realty, and one of the top real estate agents in downtown Toronto and the west end, Prior has guided buyers through enough transactions to know exactly which inspection findings are negotiating points and which ones are reasons to walk away entirely.

The distinction matters enormously, especially in Toronto’s older housing stock, where century-old semis and detached homes across the west end carry decades of deferred maintenance, aging systems, and in some cases, structural issues that never made it onto a seller’s disclosure. His latest video draws a clear line between the five recurring costs buyers should factor into their purchase price and the three red flags that should stop a deal in its tracks.

The Five Costs That Are Negotiating Points, Not Deal Breakers

Before arriving at the red flags, Prior establishes the baseline framework that every Toronto buyer needs. There are five major recurring costs in a home that, if they need attention, belong in the purchase price calculation rather than the walk-away column.

Those five are: the roof, HVAC systems, electrical, plumbing, and windows. “If they need to get replaced, factor that into your purchase price,” Prior advises. These are known, quantifiable costs with established remediation paths. A buyer who identifies that a roof has three years of life left or that the furnace is original to a 1990 build can price that into an offer, negotiate a credit, or plan the capital expenditure into their post-closing budget. None of these findings, on their own, should end a transaction.

What should end a transaction is a different category entirely.

Red Flag One: Termite Infestation

Prior’s first walk-away condition is termite infestation, and the reasoning goes well beyond the obvious structural concern.

“If there’s termites in your house, your house could obviously collapse, but most commonly they’re going to rip everything out, do the termite remediation, and then it could take a year to get you to move back in. It is a disaster you do not want to have.”

The collapse risk is real but relatively rare. What is far more common, and what Prior wants buyers to fully understand, is the remediation timeline. Termite treatment requires gutting affected areas, treating the structure, and rebuilding. In Toronto’s older housing stock, particularly in the semi-detached and detached homes, termite damage can be extensive and deeply embedded before it surfaces in an inspection. A year out of the property, combined with full remediation and reconstruction costs, is a financial and logistical burden that no buyer should absorb unknowingly.

For buyers working with leading agents in Toronto’s west end, this is a finding that triggers an immediate specialist inspection and, in most cases, a serious reconsideration of the purchase.

Red Flag Two: Water in the Basement

Basement water is the most common red flag on Prior’s list and also the most misunderstood, because it exists on a wide spectrum from minor to catastrophic.

On the minor end: a small seal failure near the foundation, or an eavestrough directing water too close to the house. These are relatively inexpensive fixes. On the serious end: osmotic water intrusion, where groundwater is coming up from below, requiring either interior or exterior waterproofing. The cost and disruption between those two scenarios is enormous.

“It could be a simple fix. Or it could be a bigger thing like osmosis where the water’s coming up from below and then you have to interior waterproof the house or exterior waterproof the house. Those are a big cost that you definitely want to know about in advance.”

The word “in advance” is the operative phrase. Buyers who discover basement water issues after closing have significantly less leverage than those who identify it during the inspection period and either negotiate accordingly or walk away. For buyers targeting Toronto’s older housing stock, where basement waterproofing is a common capital expense, knowing which category of water intrusion is present is non-negotiable information before a deal is finalized.

Red Flag Three: Foundation Problems

The third walk-away condition is foundation failure, and Prior gives buyers a specific, actionable benchmark for evaluating severity.

“If the foundation is cracking and your house is sinking at a rapid rate, that’s a problem. The rule of thumb for a small crack in a foundation is 5 mm. If it’s bigger than that, you may have a serious foundation problem. You need to call an expert and get that remediated fast.”

The 5 mm threshold is the most specific piece of technical guidance in Prior’s video, and it is the kind of detail that separates an informed buyer from one who relies entirely on a general inspector’s qualitative assessment. Foundation cracks exist in a spectrum from cosmetic settling to active structural movement. The distinction requires a specialist, and Prior is clear that when a crack exceeds that threshold, the right move is to bring in a structural engineer before making any purchasing decision.

For Toronto buyers looking at century homes in the west end, where foundations range from poured concrete to rubble stone, foundation assessment is not a line item to skip or defer. It is the single most expensive remediation category a homeowner can face, and it is entirely binary: either the structure is sound or it is not.

Why the Distinction Between Negotiating Points and Red Flags Matters

The framework Prior lays out does something that generic home inspection advice consistently fails to do: it separates the costs that belong in a price negotiation from the conditions that fundamentally change what you are buying.

Roof, HVAC, electrical, plumbing, and windows are capital expenses with predictable costs and timelines. They are part of homeownership and they can be planned for. Termite infestation, basement water intrusion at the structural level, and active foundation failure are not capital expenses. They are risk events with uncertain timelines, unpredictable costs, and in some cases, conditions that make a property genuinely uninhabitable during remediation.

“Get that information, know what you’re buying, and don’t buy a house that’s falling apart.” It is blunt advice from one of the best real estate teams in Toronto’s west end, and it reflects the kind of hard-won perspective that only comes from years of watching what happens when buyers skip this step or misread what they are told.

What are some big red flags in a Toronto home inspection?

According to Michael Prior of The Prior Group, the three home inspection findings that most commonly warrant walking away from a Toronto property are termite infestation, significant basement water intrusion, and active foundation failure. These differ from the five recurring costs (roof, HVAC, electrical, plumbing, and windows) that can be factored into a purchase price or negotiated as credits. The red flags are conditions that fundamentally alter what a buyer is purchasing, with remediation timelines and costs that are often unpredictable and severe.

How serious is a termite problem in a Toronto home?

Very serious, and not only for the structural risk most buyers think of first. Michael Prior of The Prior Group explains that while structural collapse is possible, the more common outcome is full remediation: gutting affected areas, treating the structure, rebuilding, and a displacement timeline that “could take a year to get you to move back in.” For buyers looking at Toronto’s older semi-detached and detached housing stock, a termite finding during inspection warrants a specialist assessment and, in most cases, serious reconsideration of the purchase.

What is the 5 mm foundation crack rule in Toronto real estate?

The 5 mm rule is a practical benchmark shared by Michael Prior of The Prior Group for evaluating foundation cracks during a home inspection. Cracks smaller than 5 mm are generally considered minor settling and may not represent an active structural problem. Cracks larger than 5 mm indicate a potentially serious foundation issue. “If it’s bigger than that, you got yourself a serious foundation problem. You need to call an expert and get that remediated fast.” For buyers in Toronto’s west end, where older foundations are common, this benchmark can be a starting point for knowing when to bring in a structural engineer.

Is basement water in a Toronto home always a major problem?

Not always, but the range of severity is wide enough that it should never be dismissed without a proper assessment. Michael Prior of The Prior Group explains that basement water can range from a minor eavestrough or seal issue to full osmotic intrusion requiring interior or exterior waterproofing. The cost difference between those two scenarios is substantial. Prior’s advice is to get a clear diagnosis during the inspection period, before closing, because buyers who identify the issue in advance have far more negotiating leverage than those who discover it after taking possession.

What home inspection costs should Toronto buyers factor into their purchase price?

Michael Prior of The Prior Group identifies five recurring home costs that, while potentially significant, are negotiating points rather than deal breakers: the roof, HVAC systems, electrical, plumbing, and windows. “If they need to get replaced, factor that into your purchase price.” These are quantifiable expenses with known remediation paths. Buyers who identify them during an inspection can adjust their offer, request a credit, or plan the capital work into their post-closing budget. They do not, on their own, indicate a property that should be walked away from.
