How multifamily financing actually works.

2 to 4 units vs. 5+ units: the first important distinction

A 2 to 4 unit property often follows residential or small-rental lending, where personal income, credit and occupancy can play a central role. An owner-occupied multiplex may follow a different pathway from a fully rented investment property. A 5+ unit apartment building is generally treated as commercial multifamily lending, with the building’s income central to the assessment. Legal unit count, title, mixed use and lender policy must still be confirmed.

Net operating income: start with realistic cash flow

Net operating income (NOI) is rental and other accepted property income, after allowances for vacancy and collection loss, less accepted operating expenses. Mortgage payments are not operating expenses in this calculation. Lenders may normalize expenses and rents rather than simply accept a seller’s statement.

• Actual rents and supportable other income
• Vacancy, collection loss and concessions
• Taxes, insurance, utilities, management, maintenance and other accepted expenses

DSCR: can the building carry its debt?

Debt service coverage ratio compares net operating income with required debt payments over the same period. In plain language, it measures the breathing room between the building’s operating income and its debt obligations. A lender’s accepted income, included debt payments and required coverage can differ by program. Higher rent on paper does not establish stronger coverage unless the lender accepts it.

LTV: how much debt relative to accepted value?

Loan-to-value compares the loan amount with the property value used by the lender. For acquisitions, the purchase price may also be relevant. The lender may set separate limits based on value and debt coverage; the more restrictive assessment can determine the loan. Appraised equity alone is not evidence of available borrowing capacity, and no universal LTV applies to all buildings.

CMHC-insured vs. conventional commercial financing

CMHC mortgage loan insurance protects an approved lender against default, not the borrower against having to repay. An eligible multi-unit rental building may be considered under CMHC programs through an approved lender, with insurer-specific eligibility and documentation. Conventional commercial financing is not CMHC-insured and is assessed under the lender’s own criteria. Insurance-related costs, program obligations and underwriting steps should be compared with the conventional alternative.

• Confirm property and borrower eligibility before relying on an insured pathway
• Review documentation, costs and any ongoing program obligations
• CMHC insurance does not guarantee mortgage approval

MLI Select: commitments, not an automatic shortcut

CMHC’s MLI Select framework considers affordability, energy efficiency and accessibility. Participation requires evidence and may involve ongoing commitments. Existing buildings and proposed projects need individual review under current program requirements. Do not assume that every apartment building qualifies or that particular financing terms are available.

Term and amortization: two different clocks

The mortgage term is the period before the agreement must be renewed, repaid or replaced. Amortization is the repayment schedule used to calculate instalments. Conventional commercial and insured programs may offer different amortization options. A longer schedule can reduce payments while increasing interest over time. Review payment structure, renewal risk and total cost, not just the monthly amount.

Rent rolls, vacancy and sustainable income

A rent roll identifies the suites, rents and occupancy, with lease details used to verify the income. Lenders review arrears, concessions and lease arrangements. They may allow for vacancy even in a fully leased building. Projected future rents, vacant-unit rents or proposed renovations may receive different treatment from proven collections. Ontario tenancy rules can affect assumptions; consult a qualified legal adviser rather than relying on anticipated rent increases.

The borrower and the building are both underwritten

Commercial underwriting examines more than the asset. Borrower experience, credit, liquidity, equity source and ownership structure are relevant alongside property income, condition and legal use. Lenders may require guarantees and supporting financial statements. Appraisal, environmental and building-condition work may lead to additional conditions.

From application to funding

The process generally moves from an initial discussion to document collection, lender review, conditional terms, third-party reports and legal closing. Insured files also require the applicable insurer assessment. A preliminary discussion or conditional approval is not a promise of funding. Timing and final conditions depend on the individual file.

• Clarify the purpose, unit count, location and timing
• Verify property income, borrower information and equity
• Review available structures, costs and obligations
• Complete lender, insurer and legal conditions before advancing funds
