Inspecting Investment Properties in Clarkson — What the Numbers Actually Say

Inspecting Investment Properties in Clarkson — What the Numbers Actually Say

Last month I walked through a triplex on Lakeshore Road near the Clarkson GO station with an investor from Toronto who was convinced she'd found a goldmine. The asking price was $879,500, and she'd already mentally divided it by three rental units. But when I popped that attic access, I found standing water in the roof cavity, active mold on the rafters, and what looked like a ice dam problem that'd been brewing for years. The previous owner had painted over water stains in the bedrooms. That wasn't a minor cosmetic issue — that was a $23,000 roof replacement hiding under fresh paint. By the time we got through the full inspection, what looked like a 4.2 percent cash-on-cash return was actually negative once you factored in deferred maintenance.

That's the difference between buying a property to live in and buying one to make money. I've been doing home inspections in the Greater Toronto Area for fifteen years, and I can tell you that investment property inspections demand a completely different lens than primary residence inspections. Most people understand this intellectually, but they don't know where to look or what actually matters to your bottom line.

Let me explain how investment inspections differ fundamentally from residential ones. When you're buying a home for yourself, you're looking for deal-breakers. You want to know if the foundation's cracked, if the electrical panel's dangerous, if there's asbestos. Those things matter, obviously. But with investment properties, you're calculating. You're asking: how much will this cost to fix, when do I need to fix it, and will my tenant pay for it or does it come out of my pocket? A primary residence buyer might accept deferred maintenance if the price is right. An investor needs to know the exact price of that deferral. It changes everything about how you inspect and what you report.

Here's what I'm looking for that most inspectors miss on investment properties in Clarkson. This area built a lot of rental stock in the 1970s and 1980s. That era means plumbing is often cast iron or polybutylene, both liabilities. Cast iron can last forty years, but it's at year thirty-five in many Clarkson properties. Polybutylene, which was the miracle plastic of 1978, is now known to fail catastrophically. I've seen whole insurance claims denied because the policy specifically excludes polybutylene failures. If you're looking at a property in the Applewood or Westchester neighborhoods, run the copper lines yourself or budget $8,500 to have it done professionally.

Electrical work in Clarkson rentals tells another story. The original panels are often undersized, and previous landlords — not all, but enough — have had handymen add circuits without proper permits. I inspected a five-unit building on Dundas Street last year where someone had run Romex cable through an attic that got hot in summer. The insulation was melting. That's a fire hazard and a code violation, and it's going to cost you $4,287 to bring into compliance. Insurance companies know about Clarkson's electrical legacy. Some will quote you higher premiums if they see evidence of unpermitted work.

The neighborhoods here tell you different stories. Old Clarkson, closer to the lakeshore and around the GO station, tends to be older housing stock with long-term tenancy. That's actually good — it means fewer turnovers and less tenant-caused damage. But it also means building systems are older, and landlords have kicked maintenance cans down the road for years. Westchester and Applewood are slightly newer, 1980s to 1990s construction, which sounds better until you realize that's when builders were cutting corners on HVAC and using lower-grade materials on roof sheathing. The Lorne Park area attracts investors looking at larger family homes converted to rentals, which brings its own complications around legal conformity and parking.

Now let's talk about what tenants destroy versus what's just deferred maintenance. This matters because it changes your ROI calculation. Tenant damage is often recoverable through security deposits or small claims court, though collecting is another fight entirely. Deferred maintenance is the landlord's responsibility, and it eats into every month's rent. If a tenant punches a hole in the drywall, that's on them. If the roof is leaking because the flashing wasn't maintained properly over eight years, that's your problem. I've seen landlords confuse these two categories and end up in disputes with tenants or contractors because they misunderstood who owned which failure.

Kitchens and bathrooms are where tenants do their worst. Grease buildup in exhaust ducts, caulk failure around tubs, cabinets with water damage underneath the sink where they've left their stuff stored — these are typically tenant-caused and should've been caught during move-in inspections. A proper landlord takes photos. A smart investor budgets $800 to $1,200 per turnover just for kitchen and bathroom refresh, separate from actual maintenance.

The ROI calculation itself is straightforward but demands precision. Let's say you're looking at a $650,000 property in Westchester that rents for $2,400 per month per unit (if it's a duplex or triplex). That's $28,800 annual gross rent, or a 4.4 percent gross return. Now subtract property tax, insurance, utilities you cover, maintenance reserve (I recommend 8 to 12 percent of rent), and vacancy rate (figure 5 to 8 percent in Clarkson). That $28,800 gross becomes maybe $16,000 to $17,000 net. Your real return is 2.6 percent. If the inspection reveals $15,000 in deferred maintenance, your net drops to $14,500 to $15,500. That changes your spreadsheet. Some investors would walk. Others would negotiate $20,000 off the purchase price and proceed.

The challenge is knowing what you're looking at when you're in the property. That's where experience matters. I check inspectionly.ca/city-risk-score to see what Clarkson's risk profile is, and I use that context. If the neighborhood's trending toward older landlords selling to first-time investors, I know I'm probably going to find more deferred maintenance. If the previous owner was a property management company, I expect better records but sometimes discover they deferred capital work to keep monthly costs down.

Back to that Lakeshore Road triplex — the investor and I renegotiated at $759,000, which gave her a $20,000 buffer for the roof and some electrical upgrades. She proceeded because the unit count made the math work even with the repairs factored in. But she only knew that because the inspection gave her real numbers, not guesses.

That's what you need before you commit serious capital in Clarkson.
