The single most common mistake I see new BC Interior investors make is building a cash flow model that leaves out three or four major cost categories. Then they close on a property and reality arrives. Here is the honest version of the numbers for a typical Kamloops investment property.
The Scenario
A $550,000 single-family home in Kamloops — a house with a legal suite or a property rented as a whole unit. Purchase with 20% down ($110,000), financing the remaining $440,000 at 5.29% on a 5-year fixed rate, amortised over 25 years.
The Monthly Cost Stack
Mortgage (principal and interest): $2,700/month
At 5.29% on $440,000 over 25 years, your blended monthly payment is approximately $2,700. This covers both principal repayment (which is building equity) and interest (which is a real cost). In year one, the split is roughly $430 principal and $2,270 interest per month.
Property tax: ~$300/month
Kamloops property tax on a $550,000 residential property runs approximately $3,500 to $3,800 per year depending on the neighbourhood and assessment. That works out to roughly $300 per month.
Insurance: ~$150/month
Landlord insurance — which covers the dwelling, your liability as a landlord, and loss of rental income in some policies — costs more than standard homeowner's insurance. Budget $150 per month ($1,800 per year) for a single-family rental.
Property management: ~$220/month
If you self-manage, this line item is zero. If you hire a property manager — and for a first investment property, especially if you work a day job, this is worth serious consideration — the standard Kamloops rate is 8 to 10% of collected rent. On $2,200 per month in rent, that is $176 to $220 per month.
Vacancy allowance: ~$110/month
No property is rented 100% of the time. A realistic vacancy assumption for Kamloops is 4 to 5% of annual gross rent. On $2,200 per month, that is $1,056 to $1,320 per year — call it $110 per month as a reserve.
Maintenance reserve: ~$460/month
This is the number most spreadsheets omit entirely, and it is the one that creates the biggest surprises. The standard rule of thumb is 1% of property value per year for ongoing maintenance and capital replacements. On a $550,000 property, that is $5,500 per year, or roughly $460 per month.
That sounds high until you price a new hot water heater ($1,500), a furnace replacement ($4,000 to $6,000), a roof ($12,000 to $18,000), or a full appliance replacement cycle. These costs do not arrive every month, but they will arrive. The reserve exists so you are not taking money out of your personal account when they do.
The Total
| Cost | Monthly | |------|---------| | Mortgage (P+I) | $2,700 | | Property tax | $300 | | Insurance | $150 | | Property management | $220 | | Vacancy allowance | $110 | | Maintenance reserve | $460 | | Total | $3,940 |
Rental income at $2,200 per month produces a monthly cash deficit of approximately -$1,740.
What This Actually Means
This is not a reason to avoid buying a rental property. It is a reason to go in with clear eyes about what the investment thesis actually is.
In the Kamloops market, residential investment is primarily an appreciation and mortgage-paydown play, not a cash flow play. Your tenant is covering a portion of your mortgage while the property appreciates. The $1,740 monthly shortfall is what you are contributing out of pocket — in exchange for equity building and long-term appreciation in a growing BC Interior market.
Whether that trade-off makes sense depends on your personal financial position, your timeline, and your view on Kamloops appreciation over the next decade.
How the Numbers Shift
A larger down payment improves the cash flow position significantly. At 35% down ($192,500), the mortgage drops to roughly $2,040 per month, turning the deficit from -$1,740 to approximately -$1,080. Still negative, but meaningfully better.
A duplex or property with a legal suite changes the income side. Two units generating $3,200 in combined rent versus $2,200 in single-unit rent can flip the equation closer to neutral or slightly positive, depending on the purchase price.
Lower price points also improve the picture. A $400,000 Kamloops property (typically an older home or a townhouse without a suite) with 20% down runs at a lower monthly deficit — though the maintenance reserve is still real and the appreciation upside may be lower.
The Due Diligence Implication
Before closing on any investment property, model all six cost categories with realistic numbers. If a deal only works at 0% vacancy and $200 per year in maintenance, it does not work. The properties worth buying are the ones that survive a realistic stress test — not just the optimistic scenario.
I track my own numbers in a simple spreadsheet. If you are doing the same exercise, start with these six categories before you look at anything else.
