The down payment depends on whether you live in it
This is the first fork in the road, and it changes the numbers more than anything else.
If you will live in one of the units, you are buying a home that happens to produce income, and the ordinary insured rules apply. CMHC allows up to 95% financing on an owner-occupied one- or two-unit property — 5% of the first $500,000 of lending value and 10% of the remainder — and up to 90% on an owner-occupied three- or four-unit property, meaning 10% down. The property has to be under $1,500,000 in lending value, and the maximum amortization is 25 years (CMHC).
If you will not live in it, the minimum is 20% down. CMHC's income property insurance goes to 80% LTV on two- to four-unit non-owner-occupied rentals, again over a maximum 25-year amortization (CMHC). Sagen's investment property program mirrors that at 80% LTV on two to four units (Sagen).
The practical read: a duplex you live in half of is a far cheaper entry point than the same duplex bought as a pure rental. If house-hacking is on the table at all, it is worth pricing both ways before you commit to one.
How lenders count the rent — the part that decides your file
Two properties with identical rents can qualify for very different mortgage amounts, purely because of which method the lender applies to the rental income. There are two.
- The inclusion, or add-back, method. A percentage of the gross rent is added to your income, and the property's costs stay in your debt ratios. CMHC's stated approach is that up to 50% of the gross rental income for the subject property may be included, with taxes and heat for that property excluded from the ratios.
- The net rental income, or offset, method. The property's operating costs are subtracted from the gross rent, and only the surplus is added to your income — or the shortfall subtracted from it. CMHC allows lenders to use their own internal guidelines to determine net rental income here (CMHC).
Offset is generally the more generous of the two on a property that carries itself, because the rent cancels out the expense instead of only partly covering it. Which method you get is a lender policy question, not a rule you can appeal — so the work is in taking the file to the lender whose policy suits the property, rather than taking whatever the first one offers. With 50+ lenders to choose from, that choice is a real one.
What changes as the portfolio grows
Most lenders are comfortable to a point and then start applying limits — on the number of financed properties, on total exposure to one borrower, or on how much rental income they will recognise in aggregate. The threshold varies by lender, which is exactly why the second, third and fourth purchases are often placed with different lenders than the first.
At five units in a single building, the file leaves residential lending altogether and becomes commercial. Different underwriting, different documents, and the property's own income does most of the qualifying rather than yours. Worth knowing before you fall in love with a small apartment block.
Pulling equity out of a rental you already own
A refinance on an investment property tops out at 80% of its value, the same ceiling that applies to borrowing against any home in Canada (FCAC). For a lot of investors this is the engine of the whole plan — equity from the first property becomes the down payment on the second. The two things worth checking first are the penalty on the existing mortgage and whether the new lender will still recognise the rent once the balance goes up. There is more on the mechanics on the refinance page.
Two BC rules that affect the numbers
The speculation and vacancy tax. Kelowna, West Kelowna, Vernon, Lake Country and Peachland are all designated taxable areas. For 2026 the rate is 1% of assessed value for Canadian citizens and permanent residents who are not untaxed worldwide earners, and 3% for foreign owners and satellite families, rising to 4% in 2027 (Province of BC). A property occupied by a tenant for at least six months of the calendar year may be exempt, subject to the tenancy requirements. For a long-term rental this usually resolves itself — it is the property sitting empty between plans that gets expensive.
Short-term rentals in Kelowna. The rules changed on 1 June 2026, and the change is narrower than most coverage suggested. It matters enough to be worth getting exactly right, so it has its own section below.
What I actually do on a rental file
Before anything else, I work out which lender's rental income policy your specific property fits, because that single choice usually moves the qualifying number more than the rate does. Then I look at the structure — whether the down payment is best pulled from an existing property or held as cash, how this purchase affects the next one, and whether the amortization and term you are being offered still work in three years' time. Bring me a listing and a rough rent figure and I can tell you where it lands.
Kelowna's short-term rental rules changed — carefully
This is the local detail most people get wrong at the moment, and getting it wrong is expensive, so it is worth being precise.
On 1 June 2026 Kelowna became the only local government in British Columbia to be released from the province's principal residence requirement for short-term rentals this year, ahead of a wider opt-out window opening in 2027. That is genuinely significant. It is also far narrower than the headlines suggested: the exemption applies only to properties that have been rezoned into the city's short-term rental sub-zone, and the city has identified roughly 25 eligible properties (City of Kelowna). Everywhere else in Kelowna the principal residence requirement still applies, which means you must live in the property at least 240 days a year to rent it short-term.
So if someone is telling you that Kelowna has opened up for Airbnb investment, check the zoning of the specific address before you believe it. You will also still need a municipal business licence — $50 to apply and $345 a year — provincial registration, and, in a strata, bylaws that actually permit it. A strata can prohibit short-term rentals regardless of what the city and the province allow.
What that means for the financing
Almost no lender will underwrite projected short-term rental income the way they will a signed long-term lease. If your plan depends on nightly rates, expect to qualify on the long-term rental value of the property, or on your own income, and treat any upside as yours rather than the lender's. That single point decides the affordability of most Okanagan investment files.
On the numbers: in July 2026 the Central Okanagan single-family benchmark sat at $1,072,400, up 2.3% year over year, with townhomes at $709,500 and condominiums at $490,700 (Association of Interior REALTORS). A rental purchase needs 20% down, so a benchmark condominium implies roughly $98,000 and a benchmark house roughly $215,000 before closing costs. Long-term rental demand around UBCO and Kelowna General is steady, and it underwrites far more predictably than tourism does.
