The first number any Kamloops investor hears when they look at an income property is the CAP rate. It's on every listing sheet, every agent email, every investor forum post. "Strong 5.8% CAP." "Priced at a 6.2 CAP." It gets quoted like it's the one number that settles the deal.
It isn't. Not even close.
After digging through dozens of listings across Kamloops, Merritt, and the Thompson-Okanagan corridor, I've come to treat headline CAP rates the same way I treat marketing copy: directionally useful, structurally misleading. Here's what's actually going on, and what I look at instead.
What CAP Rate Is — and What It Isn't
The formula is simple: Net Operating Income divided by Purchase Price. A $600,000 property generating $34,800 in NOI has a 5.8% CAP rate.
That number tells you something real: roughly how much income the property produces relative to its value, before you bring in any financing assumptions. If you're buying all-cash and comparing two identical properties in the same market, CAP rate is a reasonable shorthand.
The problem is that almost no one buying in Kamloops is buying all-cash. And almost no property analysis in a listing package is using realistic NOI.
CAP rate ignores financing entirely. A property with a 5.8% CAP and a mortgage at 5.4% looks like a thin but positive spread. But factor in 20% down, CMHC premiums if applicable, property transfer tax, and any deferred maintenance you're absorbing at purchase — the actual cash-on-cash return on your deployed capital can be half the headline CAP rate or worse. The CAP rate doesn't know or care about your debt structure. That's not a quirk; it's definitional. But most investors treat it as though it tells them something about what they'll actually earn.
CAP rate assumes 100% occupancy. This is the assumption that kills more BC Interior analyses than any other. The calculation in most listing packages uses gross scheduled rent — the number you'd collect if every unit was occupied, every month, with zero turnover. That's not a realistic assumption for any property. It's not even a conservative assumption. It's a fantasy presented as a baseline.
The NOI being used is often gross rent, not net. Legitimate NOI subtracts operating expenses: property management (typically 8–10% of gross rents in Kamloops), maintenance and repairs, property taxes, insurance, and a reserve for capital expenditures. What I see on listing sheets, repeatedly, is a number calculated against gross rents with "expenses" listed as property tax and insurance only — nothing for management, nothing for maintenance, nothing for eventual roof, hot water tank, or appliance replacement.
The Three Ways BC Interior CAP Rates Get Inflated
I've seen the same patterns repeat across Kamloops and Kelowna listings.
Stale rent figures. A property with tenants paying $1,400/month for a two-bedroom that would rent at $1,650 on the open market gets listed with the $1,400 rents in the cash flow analysis — because that's the defensible number — but the CAP rate in the headline reflects a pro forma at market rents. Sometimes it's the reverse: above-market rents from a previous lease cycle get used to juice the numbers on a property the seller knows will see turnover. I've seen both. The question to always ask is: are these actual rents or projected rents, and when were they set?
Vacancy gets ignored or set at 1–2%. In a market like Kamloops, long-term vacancy on a well-managed property might average 3–5% annually. That accounts for turnover time, the gap between tenants, the occasional month where a unit needs work before re-listing. A 1% vacancy assumption is not analysis; it's optimism. On a $3,000/month gross rent property, the difference between 1% and 5% vacancy is $1,440 per year — which at a 5.8% CAP represents nearly $25,000 in implied property value. That's not a rounding error.
No maintenance reserve. The Capital Expenditure reserve is the line item that separates professional analysis from back-of-envelope math. Most practitioners recommend reserving 1–2% of property value annually for CapEx (roofs, HVAC, plumbing, appliances). On a $600,000 property, that's $6,000–$12,000 per year that isn't showing up in the NOI calculation on most listing sheets. It's not imaginary money. Eventually you spend it.
A Worked Example: The 5.8% That Pencils at 4.2%
Here's a real-ish scenario from a property type I've analyzed repeatedly in Kamloops — a four-unit residential building listed at $620,000.
Listing sheet says:
- Gross rents: $6,800/month ($81,600/year)
- Listed expenses: property tax $4,200 + insurance $2,400 = $6,600
- NOI: $75,000
- CAP rate: $75,000 / $620,000 = 6.05%
Looks reasonable. Now let's run real numbers.
Adjusted analysis:
- Gross scheduled rent: $81,600
- Vacancy at 4%: -$3,264
- Effective gross income: $78,336
- Property tax: $4,200
- Insurance: $2,400
- Property management at 9%: $7,050
- Repairs and maintenance (estimate): $4,000
- CapEx reserve at 1.25% of value: $7,750
- Total operating expenses: $25,400
- Actual NOI: $52,936
- Actual CAP rate: $52,936 / $620,000 = 4.2%
That's a 1.85-point gap. On a $620,000 property, the difference in implied value at the same CAP rate is over $270,000. You're not buying what the listing says you're buying.
What I Use Instead
CAP rate has its place — it's useful for comparing unlevered returns across markets, and it's the industry standard for commercial valuation conversations. But for my actual go/no-go decisions on BC Interior residential income properties, I run cash-on-cash return against three scenarios: base case, conservative, and stress.
Cash-on-cash measures what I actually earn on the cash I actually deploy: annual pre-tax cash flow divided by total cash invested (down payment, closing costs, immediate repairs). It incorporates financing, which is where most BC Interior investors live or die.
My baseline assumptions for Kamloops analysis: 5% vacancy, 9% property management, 1.5% CapEx reserve, and maintenance at $200/unit/month. If a property still pencils at 7%+ cash-on-cash under those assumptions at current financing rates, I'll look harder at it. If it doesn't, the headline CAP rate doesn't change that.
Kamloops vs. Kelowna: Where This Matters More
In Kelowna, the CAP rate inflation problem is even more pronounced because the market has been more aggressively bid up and more investors are willing to accept negative cash flow in exchange for appreciation. CAP rates in Kelowna regularly trade in the 3.5–4.5% range on residential income properties, and buyers rationalize it with appreciation assumptions that may or may not materialize.
Kamloops has historically traded at a slight premium to Kelowna on CAP rates — more like 4.5–5.5% on honest numbers — which is part of why the cash flow math is at least possible there. But the listing-sheet CAP rate inflation is just as bad. The market is smaller, so there's less transaction data to pressure-test the numbers against, which means individual listings can carry more distorted assumptions without being called out.
The work is the same in both markets: get the actual rent rolls, get the actual expense history, and rebuild the NOI from scratch. The headline number is a starting point for a conversation, not an answer.
If a seller or agent pushes back on your adjusted numbers, that's useful information too.
