Financing Your Multiplex Purchase

What is the minimum down payment for a multiplex in Canada?

For owner-occupied multiplexes up to $999,999, the minimum down payment is 5% on the first $500,000 and 10% on the remainder — so a $750K purchase requires $50,000 down and a $900K purchase requires $65,000. Under CMHC rule changes effective December 2024, multiplexes priced between $1M and $1.5M now qualify for insured mortgages using the same tiered structure. On a $1.2M multiplex, the minimum down is $95,000 — significantly less than the previous 20% rule ($240,000). The CMHC insurance premium (up to 4% of the loan amount) is added to your mortgage balance rather than paid upfront, which lets buyers enter the market with less cash at closing.

The December 2024 CMHC rule change was significant — previously, anything over $999,999 required 20% down. Now the same purchase needs only the tiered amount. The trade-off is the CMHC insurance premium: on a $750K purchase with $50K down, that premium is roughly $28,000. You pay interest on it for the life of the loan, so the true cost is higher than the premium alone.

Can rental income help me qualify for a mortgage?

Yes — this is the most important financing tool for multiplex buyers in BC. Most lenders allow you to add 50% of projected rental income from secondary suites to your gross qualifying income. For a duplex suite renting at $2,300/month, that adds $1,150/month to your stated income — which translates to roughly $80,000–$120,000 in additional borrowing power at current mortgage rates. Some credit unions and monoline lenders use up to 80% of rental income with strong market documentation. Your mortgage broker needs to submit comparable rental listings or a rental market appraisal to support the projected rent figure.

The key is having realistic rent projections backed by comparable listings in the same neighbourhood. You cannot inflate the number — lenders will compare it against market data. Ask your broker specifically which lenders have the most favourable rental offset policies, because the difference between 50% and 80% offset can mean $40K–$60K in additional qualification room.

What is the FHSA and how does it help homebuyers?

The First Home Savings Account (FHSA) lets first-time buyers contribute up to $8,000 per year (lifetime maximum $40,000). Contributions are tax-deductible — they lower your taxable income in the year you make them, just like an RRSP. Withdrawals for a qualifying home purchase are completely tax-free, including any investment gains. You can combine an FHSA withdrawal with the Home Buyers' Plan (up to $60,000 from your RRSP), giving first-time multiplex buyers access to up to $100,000 in tax-advantaged down payment funds if both accounts are maximized. The FHSA must be open for at least one calendar year before you can make a qualifying withdrawal.

Unused annual contribution room ($8,000) carries forward to the following year, so if you miss a year you can contribute $16,000 the next. The FHSA is particularly powerful for BC buyers because multiplexes often require larger down payments — every tax-free dollar in your FHSA is worth more than a dollar saved in a taxable account.

What government programs help multiplex buyers in BC?

BC and federal programs that apply to multiplex buyers include: the BC First-Time Home Buyers' Program (Property Transfer Tax exemption on the first $500,000 of price for homes up to $835,000, saving up to $8,000 at closing); the federal Home Buyers' Plan (up to $60,000 RRSP withdrawal, tax-free, with 15 years to repay); the First Home Savings Account (FHSA, up to $40,000 tax-free); the GST New Housing Rebate (up to $6,300 back on new builds); and 30-year amortization for first-time buyers purchasing new construction. For brand new multiplexes, the PTT New Home Exemption also applies to purchases under $1.1M.

Stack these programs strategically. The BC PTT exemption + federal FHSA + Home Buyers' Plan can put $100K+ in tax-advantaged funds toward your down payment. On a new-build multiplex, add the GST rebate and 30-year amortization and the effective entry cost drops further. Talk to a mortgage broker who specializes in multiplexes — they will know which programs apply to your specific situation.

Can I really use rental income to qualify for a bigger mortgage?

Yes — and it is the reason many buyers can afford a multiplex they couldn't otherwise qualify for. Most lenders count 50% of projected rental income from the units you don't occupy toward your qualifying income. On a fourplex where three suites rent at $2,200/month each, that adds $3,300/month ($39,600/year) to your stated income for qualification purposes. At current stress-test rates, that translates to roughly $200,000–$250,000 in additional borrowing power. Some credit unions and B-lenders use 80% of rental income with proper documentation, adding even more capacity. The income must be supported by a rental market appraisal or comparable listings — you cannot project above-market rents.

Is house-hacking a multiplex actually worth the hassle?

For most buyers in their 30s and 40s who want to build equity faster, yes. Living in one unit of a duplex or fourplex and renting the others cuts your effective housing cost by 30–60%. On a $1M duplex with a $4,700/month mortgage, a $2,400/month rental suite drops your net monthly cost to under $2,300 — less than many one-bedroom rentals in Vancouver. The trade-off is that you become a landlord under BC's Residential Tenancy Act: tenant screening, rent-increase limits (2.3% in 2026), and maintenance calls are real responsibilities. For buyers who are organized and comfortable with that role, house-hacking is one of the strongest wealth-building strategies in Metro Vancouver.

The financial case is strong. Living in one unit of a duplex and renting the other can cut your effective housing cost by 30-50%. On a $900K duplex with a $4,200/month mortgage, a $2,500/month rental suite drops your net cost to $1,700. That is less than renting a one-bedroom in many parts of Vancouver. The downsides are real though. You are now a landlord under BC law, which means you must follow the Residential Tenancy Act for everything — rent increases capped at 2.3% in 2026, 4-month notice for landlord-use eviction, and mandatory use of the RTB portal for all notices. You will field maintenance calls at inconvenient times. Your tenant's noise is your noise. And the tax complexity is significant: you must declare rental income, can deduct a portion of mortgage interest and expenses, and may face capital gains implications on the rental portion when you sell. For people who are handy, organized, and comfortable setting boundaries with neighbours, house-hacking is one of the best wealth-building strategies available in Vancouver. For people who value total privacy and hate administrative work, a condo might be the better call.
