I own six rental doors myself, so when someone asks me whether becoming a landlord in BC is worth it, I don't answer with a pep talk. I answer with the same math I use before I buy anything. These are the four questions every first-time investor asks me, and the honest answers.
1. What's the down payment on a rental?
This is the first place the rules diverge from buying your own home. A property you'll live in can go as low as 5% down. A non-owner-occupied rental in Canada requires at least 20% down, full stop. The nuance most people miss: if you buy a place with a suite and live in one unit yourself, you may qualify under the lower owner-occupied rules, which can be a powerful way into your first investment.
2. How do lenders count rental income?
Here's the detail that quietly decides whether you qualify: lenders don't all treat rent the same way. Some count only 50% of the rental income toward your application, others 80%, and a few will use the full amount with the right documentation. That single difference can be the line between "approved" and "sorry, not this time." Matching your file to a lender whose rules fit your numbers is exactly where an agent earns their keep.
Two lenders can look at the identical property and rent, and offer you completely different borrowing power. Knowing which door to knock on is half the game.
3. What do the real numbers look like?
A deal that "cash flows" on the back of a napkin often doesn't once you account for everything. Before I make an offer, I run the full picture: realistic rent for that exact town, the true mortgage payment, property taxes and insurance, strata fees if any, a vacancy allowance, and a monthly set-aside for maintenance and big-ticket repairs. If it only works at 100% occupancy with zero surprises, it isn't a deal, it's a hope.
4. How do you finance more than one?
Your second, third, and fourth properties each get harder in a different way. Lenders cap how many mortgages they'll hold for one borrower, and each new door changes how they see your debt and income. That's why the order you buy in, and which lender you use for each, matters as much as the rate. When you're building a portfolio, I plan the financing as a sequence, not one deal at a time, so an early choice doesn't block a later purchase.
Everything here is the same math I use to run my own six doors. Nothing theoretical, just the numbers that decide whether a rental helps or hurts.
Down payment rules at a glance
| Property type | Minimum down |
|---|---|
| Owner-occupied (1–2 units) | 5% |
| Owner-occupied with rental units (2–4 units) | 10% |
| Non-owner-occupied rental (any size) | 20% |
If you plan to live in one unit of a multi-unit property, you may qualify for the lower owner-occupied down payment on the whole building, one of the most underused strategies for new investors. Note that mortgage default insurance isn't available on pure rental purchases under 20% down, which is why that threshold exists.
How lenders count rental income
Lenders don't count 100% of your expected rent toward qualifying. Most use one of two methods:
| Method | How it works |
|---|---|
| Offset method | 50–80% of the rent is subtracted from the mortgage payment before your debt ratios are calculated. |
| Add-back method | A percentage of gross rent is added directly to your income, then standard debt ratios apply. |
This is exactly why shopping multiple lenders matters for a rental: the gap between an 80% offset and a 50% offset can be the difference between qualifying and not, on the same property, with the same income.
The real numbers: a worked example
Here's the basic cash-flow math on a sample $500,000 rental:
| Monthly rent (estimated) | $2,400 |
| Mortgage payment (20% down, 5.5%, 25yr) | −$2,290 |
| Property tax (est.) | −$210 |
| Insurance (est.) | −$85 |
| Maintenance reserve (5% of rent) | −$120 |
| Monthly cash flow | −$305 |
Negative cash flow isn't automatically a bad deal, plenty of investors accept a monthly shortfall in exchange for appreciation and mortgage paydown. But you should know the number going in, not after.
Choosing the right mortgage structure
Fixed vs. variable. Fixed gives you predictable cash flow for underwriting the next purchase; variable can save money long-term but adds payment uncertainty, which matters more as you stack properties.
Amortization length. A longer amortization lowers your monthly payment, helping cash flow and qualifying for the next property, at the cost of more interest over time.
Prepayment privileges. If your plan is to pay down debt and refinance to pull equity for the next purchase, look for flexible prepayment terms.
A note on taxes
Rental income is taxable, and expenses like mortgage interest, property tax, insurance, and maintenance are generally deductible. Depreciation (capital cost allowance) can reduce taxable income but affects your cost basis when you sell. This isn't tax advice, talk to an accountant who works with real estate investors before you file.
If you've got a specific listing in mind, send it over, I'll run it through the same framework I use for my own money. For a deeper dive across the province, my post on vetting a rental anywhere in BC walks through the market-by-market differences.
