A standard multi-family construction project in the Metro Vancouver region typically requires a financing stack rather than a single loan. The most common components are home equity, construction financing, equity contribution, and — for qualifying projects — CMHC-insured rental financing. This page outlines what each component is and where it commonly applies in Port Moody fourplex projects.
All construction cost and interest rate figures below are general industry ranges as of 2026 and should be confirmed against current quotes from licensed professionals before being relied upon for any specific project.
1. Home Equity Lines of Credit (HELOCs)
A HELOC is a revolving line of credit secured against the equity in an existing home. In British Columbia, lenders generally allow homeowners to borrow up to 65–80% of a home's appraised value, less any outstanding mortgage balance.
HELOCs are commonly used to fund smaller projects (such as a laneway home or interior suite addition) or the early stages of a larger build, such as design, permitting, and demolition costs. A HELOC secured against an existing home must be discharged before that home can be demolished. For full-redevelopment projects, the HELOC is typically replaced by construction financing once demolition begins.

2. Construction loans (progress draw mortgages)
A construction loan, sometimes called a progress draw mortgage, advances funds in stages tied to defined construction milestones. Typical milestones are foundation completion, framing complete, lock-up (roof and windows installed), drywall complete, and substantial completion.
Lenders generally cap construction loan amounts at the lower of:
- A defined percentage of total project cost (commonly 70–80%), or
- A defined percentage of the project's as-complete value (commonly 70–80%).
The lower of the two figures applies. The borrower's equity contribution must cover the difference.
Interest rates on construction loans in British Columbia in 2026 are commonly quoted at a margin above the prime rate. [VERIFY: confirm current rate ranges with a lender or broker — interest rate environments change frequently.]
3. CMHC MLI Select for projects with five or more units
The Canada Mortgage and Housing Corporation (CMHC) administers a program called MLI Select for purpose-built rental construction. The program offers favourable terms — including amortizations of up to 50 years and reduced insurance premiums — to projects that meet defined affordability, energy efficiency, or accessibility criteria.
MLI Select requires a minimum of five units. A standard fourplex does not qualify on its own. Lots within 400 metres of frequent transit that qualify for six units under SSMUH may meet the threshold, as may joint projects across adjacent lots.
Full program criteria are published on the CMHC MLI Select page.
4. Joint ventures and co-development structures
In a joint venture structure, a property owner contributes land and a development partner contributes construction capital and management. Proceeds at completion are typically distributed according to a pre-agreed equity ratio, which depends on the relative contributions and the specific deal structure.
Two common variations:
- Equity share: Both parties retain ownership through construction. Profits at sale or refinancing are split per the agreed ratio.
- Build-to-suit with buyout: The developer purchases the lot outright (often at a development-value premium) and builds on their own balance sheet. The original owner receives cash at closing.
Both structures involve significant legal and tax considerations. Property owners considering joint ventures should consult a real estate lawyer and an accountant familiar with multi-unit development before entering any agreement.
5. Land sale to a developer
For property owners who do not wish to undertake construction directly, an alternative is to sell the lot to a developer. Lots eligible for multi-unit construction under SSMUH have generally been transacting at a premium relative to their prior single-family use value, as developers price in the expanded development potential. The size of any premium depends on market conditions at the time of sale, lot characteristics, and the specific development potential under current zoning.

Typical financing stack for a Port Moody fourplex
A representative financing stack for a fourplex project in Port Moody in 2026 might combine:
- Existing home equity (drawn down through a HELOC during the design and permitting phase)
- A construction loan (replacing the HELOC at the start of construction)
- A cash equity contribution from the property owner (covering soft costs and contingency)
- Long-term take-out financing or unit-by-unit sales at completion
The specific structure depends on the property owner's equity position, income profile, project size, and intended outcome (rent, sell, or owner-occupy).

Frequently asked questions
What does it cost to build a fourplex in Port Moody?
Construction costs vary significantly depending on lot conditions, design complexity, and finish level. Industry estimates for Metro Vancouver in 2026 generally range from CAD $1.4 million to $2.2 million in hard construction costs for a typical fourplex, with soft costs adding a further 10–18%.
What is CMHC's MLI Select program?
MLI Select is a CMHC program offering favourable financing terms for purpose-built rental projects of five or more units that meet defined affordability, energy efficiency, or accessibility criteria. Standard fourplexes do not qualify because they fall below the five-unit threshold.
Can a HELOC fund a multiplex construction project?
A HELOC can fund smaller projects or the early phases of a larger project. It is typically not sufficient on its own for a full fourplex build. A HELOC secured against an existing home must be paid out before that home is demolished.
What is a construction loan?
A construction loan advances funds in stages tied to defined construction milestones — typically foundation, framing, lock-up, drywall, and completion. Loan amounts are generally capped at a percentage of either project cost or projected as-complete value.
What is the typical equity contribution required for a Port Moody fourplex?
Equity contributions vary by lender and project structure. A common range is 20–30% of total project cost, though figures depend on the lender's underwriting and the borrower's credit profile.
