Refinancing an apartment building is one of the most powerful wealth-building strategies available to Canadian real estate investors. It lets you pull out equity youβve built through appreciation and rent growth, redeploy that capital into new deals, and still keep your building generating cash flow.
But refinancing multifamily properties is more complex than refinancing a single-family home. There are different programs, strict underwriting criteria, and real numbers that determine whether your refinance actually works.
This guide walks you through the complete process of refinancing an apartment building using CMHC programs, real numbers, and exactly what lenders want to see.
Why Refinance Your Apartment Building?
Refinancing makes sense when you have specific financial goals. Hereβs what refinancing can accomplish:
Access Equity for New Investments
You bought a 12-unit building five years ago for $2.5 million. The market has appreciated, and today itβs worth $2.8 million. Youβve also paid down some principal. Now your property is worth $2.8 million but your mortgage balance is only $1.9 million.
You can refinance at 85% LTV ($2.38 million), pay off the old $1.9 million mortgage, and pocket the differenceβroughly $480,000 in equity. Use that to buy another building, fund renovations, or diversify into a different investment.
Lower Your Interest Rate
Rates dropped. Your original CMHC mortgage was at 5.25%. Today, CMHC mortgages are available at 4.50%. If you have $2 million outstanding on a 40-year amortization, dropping your rate by 0.75% saves you roughly $12,500 per year in interest. Over the remaining term, thatβs substantial.
Extend Your Amortization
Your original mortgage has 18 years left on a 25-year amortization. Monthly payments are eating into your cash flow. Refinance to a fresh 40-year amortization through CMHC, and your monthly payment drops. Better cash flow now.
Switch from Private to CMHC Lending
Maybe you bought with a bridge or private lender at 8% interest for three years while you stabilized the property. Now the building has strong cash flow and clean financials. Refinance to CMHC MLI Standard at 4.50% with a 40-year amortization. Your payment drops dramatically, and youβve moved from short-term expensive debt to long-term stable institutional financing.
CMHC Refinance Programs: MLI Standard vs MLI Select
Both of CMHCβs multi-unit programs are available for refinancing. Which one you choose depends on your property and goals.
CMHC MLI Standard Refinance
MLI Standard is the straightforward refinance option. Use it when:
- Youβre refinancing an existing, stabilized property with consistent rental income and good occupancy
- You have adequate cash flow (DSCR of 1.10+) to support the new mortgage
- You donβt need maximum leverageβup to 85% LTV is enough
- You want simplicity and speedβapproval in 4-8 weeks, no points system
MLI Standard refinance terms:
- Maximum LTV: 85%
- Maximum amortization: 40 years
- Minimum DSCR: 1.10-1.20x
- Insurance premium: 1.50%-4.50% (calculated on the new mortgage amount)
- Timeline: 4-8 weeks to CMHC approval
For most apartment building refinances, MLI Standard is the right choice.
CMHC MLI Select Refinance
MLI Select is available for refinancing, though itβs less common than MLI Standard in refi scenarios. Use MLI Select when:
- Youβre refinancing to fund property improvements that add points (energy retrofits, accessibility upgrades)
- You need maximum leverage (up to 95% LTV) to pull more equity
- Youβre willing to accept a longer approval timeline (10-16 weeks) for better terms
- Your building is pursuing energy efficiency or affordability commitments that generate value-add points
For a straightforward rate-and-term refinance or cash-out refi of an existing building without upgrades, MLI Standard is simpler and faster.
Apartment Building Refinance Requirements
Before you contact a lender, understand what CMHC wants to see. Theyβre not going to refinance every building at 85% LTV. Your propertyβs actual cash flow determines how much you can borrow.
Property Requirements
Your building must be:
- 5+ self-contained residential units β no hotels, motels, shared-kitchen student residences, or mixed-use buildings with primarily commercial space
- Stabilized and performing β not in turnaround mode. Occupied at 90%+ with documented, sustainable rental income
- In good physical condition β no deferred maintenance or major capital needs requiring immediate investment. If youβre considering renovations, construction financing may be appropriate
- Clean environmental record β Phase I environmental assessment (Phase II if Phase I shows concerns)
Borrower Requirements
You must demonstrate:
- Real estate ownership experience β evidence youβve owned and managed multi-unit properties
- Adequate net worth β minimum 25% of the new loan amount or $100,000, whichever is greater
- Liquidity β typically 10% of the project cost in readily available funds
- Clean credit and tax compliance β no recent bankruptcies, liens, or tax arrears
- Full documentation β personal tax returns (2-3 years), corporate returns if applicable, credit authorization
Property Performance: The DSCR Rule
This is the critical part. CMHC evaluates your propertyβs Debt Service Coverage Ratio (DSCR). This is your propertyβs annual NOI divided by annual mortgage payments.
Formula: DSCR = Annual NOI Γ· Annual Debt Service
CMHC typically requires 1.10-1.20x minimum DSCR. This means your net operating income must be at least 10-20% higher than your annual mortgage payment. A property that barely breaks even wonβt qualify at high LTV.
Example: A property with $300,000 annual NOI can service about $272,000 in annual debt payments (at 1.10x DSCR). If your mortgage payment exceeds that, CMHC wonβt approve the refinance at that LTVβyouβll need to put more equity down.
When NOT to Refinance Your Apartment Building
Refinancing isnβt always the right move. Here are scenarios where you should hold off:
Your Mortgage Has a Large Prepayment Penalty
Many private mortgages charge 3-5% prepayment penalties if you pay off early. If your current mortgage balance is $1.9 million and youβd owe a 4% penalty to break it, thatβs $76,000. CMHCβs refinance needs to justify that cost in savings. If your rate drop saves you $10,000 per year, it takes 7.6 years to recoup the penalty. Make sure the math works.
Your Building Hasnβt Appreciated
You paid $2.5 million for your building. Today itβs appraised at $2.45 million (values can decline). Your current mortgage is $1.8 million. At 85% LTV, you can only refinance to $2.08 million. You canβt access much additional equity. A refinance doesnβt make sense unless youβre just lowering your rate.
Your DSCR Is Weak
Youβre breaking even or in slightly positive cash flow. Your propertyβs annual NOI is $150,000, and youβre currently paying $145,000 in annual debt service (1.03 DSCR). If you refinance and pull out equity, your new mortgage payment might jump to $165,000 annually. Your DSCR drops to 0.91. You donβt qualify. CMHC wonβt approve it.
Youβre Better Off Selling
Sometimes the best move is to sell. If your building is aging, rents are stagnant, and expenses are climbing, refinancing just extends your problem. Sell the building, take your equity gains, and deploy capital into a better asset.
The Apartment Refinance Process: Step by Step
Step 1: Evaluate Your Current Situation
Before contacting a lender, know your numbers:
- Current property value (ballpark, youβll get a formal appraisal later)
- Current mortgage balance and rate
- Propertyβs annual NOI (gross rental income minus operating expenses)
- Any prepayment penalties on your current mortgage
- Your personal net worth and liquid assets
- When your current mortgage matures or renews
Gather 2-3 years of operating statements. CMHC wants to see actual rent rolls, lease terms, expense records, and evidence of sustainable income.
Step 2: Pre-Qualification with a CMHC-Approved Lender
Contact a mortgage broker or lender experienced in multifamily refinances. Provide your preliminary numbers. A good lender will tell you:
- What approximate LTV and loan amount you might qualify for
- Estimated interest rate range
- Rough timeline
- Any obvious red flags
Pre-qualification takes 1-2 weeks and costs nothing. It filters out deals that wonβt work before you spend money on an appraisal.
Example: You say youβre refinancing a $2.8 million property with $300,000 annual NOI and your current mortgage is $1.9 million. A lender might respond: βAt 85% LTV, you could borrow about $2.38 million. Your DSCR would be approximately 1.15x at current 4.50% rates. We think this will qualify. Letβs move forward with a formal application.β
Step 3: Order the Appraisal
Once pre-qualified, your lender orders a formal appraisal ($1,500-$3,000). CMHC uses this appraised value to determine your maximum LTV and loan amount. The appraisal includes:
- Current property condition and recent capital improvements
- Comparable sales in your area
- Unit mix, age, rental rates, and lease terms
- Operating expenses and cash flow analysis
The appraisal is the foundation for everything that follows. If it comes in lower than expected, your refinance numbers change.
Step 4: Submit Formal Application
Once you have an appraisal, submit your formal CMHC application. Youβll provide:
- Completed CMHC application forms and property schedules
- Appraisal report
- Environmental Phase I assessment
- Current rent roll with lease copies
- 2-3 years of operating statements and tax returns
- Personal financial statement and tax returns
- Personal credit report authorization
- Business plan if youβre making property improvements
Your lender assembles this package and submits to CMHC.
Step 5: CMHC Underwriting and Review
CMHC reviews your application over 4-8 weeks. They evaluate:
- Appraisal validity β does the appraised value support the loan?
- Income sustainability β are rents realistic? Is the market strong?
- Expense analysis β are operating expenses reasonable or understated?
- DSCR sufficiency β can the property support the proposed mortgage payment?
- Borrower strength β is your net worth and experience adequate?
CMHC may request additional documentation, property inspections, or clarifications on the operating statement. Expect back-and-forth during this phase.
Step 6: Commitment Letter and Closing
If approved, CMHC issues a Commitment Letter specifying the approved loan amount, rate, amortization, insurance premium, and any conditions. You have 90-120 days to close.
At closing, you:
- Pay your closing costs (legal, appraisal, broker fees)
- Pay or finance the CMHC insurance premium
- Sign mortgage documents
- Receive funds to pay off old mortgage and keep difference as equity access
Total timeline: 4-8 weeks from formal application to CMHC commitment, then 2-4 weeks to closing. Plan on 6-12 weeks total.
Real Example: Refinancing a 15-Unit Apartment Building
Letβs walk through a realistic scenario with actual numbers.
Property Details
- Property: 15-unit apartment building in Calgary
- Originally purchased: 5 years ago for $2.0 million
- Current appraised value: $2.8 million (8% annual appreciation)
- Current mortgage: $1.6 million at 5.10%, 20 years remaining on 25-year amortization
- Current monthly payment: $9,200
- Gross annual rental income: $225,000 (average $15,000/unit/year)
- Operating expenses: $72,000/year (32% of gross incomeβreasonable)
- Annual NOI: $153,000
Refinance Analysis
CMHC MLI Standard refinance at 85% LTV:
- Appraised value: $2.8 million
- Maximum mortgage (85% LTV): $2.38 million
- Current mortgage payoff: $1.6 million
- Equity accessible (cash-out): $2.38M - $1.6M = $780,000
- CMHC insurance premium (approximately 3.75% for 80-85% LTV): $89,250
New mortgage total (if premium financed): $2.38M + $89,250 = $2.469 million
Debt Service and Cash Flow
Current mortgage:
- Annual payment: $110,400
- DSCR: $153,000 Γ· $110,400 = 1.39x β Strong
Refinanced mortgage at CMHC terms:
- Rate: 4.50% (market rate, negotiable)
- Amortization: 40 years (new CMHC term)
- Total mortgage: $2.469 million
- Monthly payment: $12,523
- Annual payment: $150,276
- New DSCR: $153,000 Γ· $150,276 = 1.02x β Marginal
Hmm. The refinance pulls out $780,000 in equity, but the increased mortgage payment drops DSCR to 1.02x. CMHC requires minimum 1.10x. This refinance structure doesnβt work as proposed.
Solution: Reduce the Cash-Out Amount
Instead of pulling maximum equity, pull only what the DSCR supports:
- Required annual debt service at 1.10x DSCR: $153,000 Γ· 1.10 = $139,091
- At 4.50%, 40-year amortization: maximum mortgage = $2.05 million
- Equity accessible: $2.05M - $1.6M = $450,000
- Insurance premium on $2.05M (3.75%): $76,875
- New total mortgage (with premium financed): $2.127 million
New mortgage details:
- Monthly payment: $10,774
- Annual payment: $129,288
- New DSCR: $153,000 Γ· $129,288 = 1.18x β Approved
The Outcome
You refinance and access $450,000 in equity while maintaining healthy 1.18x DSCR. Your monthly payment increases slightly from $9,200 to $10,774 (+$1,574/month) because your new mortgage is larger. But you now have $450,000 to:
- Buy another rental property
- Fund major renovations (roof, HVAC, windows)
- Pay down personal debt
- Build a cash reserve
The refinance works because you sized the equity withdrawal to match the propertyβs actual cash flow capacity.
Cash-Out Refinance vs. Rate-and-Term Refinance
There are two types of apartment refinances:
Cash-Out Refinance
You refinance and pull equity out (like the example above). You borrow more than your current mortgage balance and pocket the difference. The new debt service must still meet CMHCβs DSCR requirements.
Advantages:
- Access equity for other investments
- Improve cash flow by extending amortization
- Consolidate high-interest debt
Disadvantages:
- Increased mortgage payment reduces cash flow
- Must maintain adequate DSCR (limits how much you can pull out)
- Youβre borrowing more, increasing total interest paid
Rate-and-Term Refinance
You refinance without pulling equity. You borrow the same amount as your current mortgage balance (or slightly less if you want to pay down principal). The goal is simply to lower your rate or extend your amortization.
Advantages:
- Lower payment improves cash flow immediately
- Simpler underwritingβless scrutiny on DSCR
- Faster approval
Disadvantages:
- You donβt access any equity
- Limited to lowering rates or extending amortization
For rate-and-term refis, CMHC is more flexible on DSCR. Theyβre less concerned because youβre not increasing leverage. For cash-out refis, theyβre stricter because youβre pulling more equity and the property needs to support higher debt service.

- DSCR is the limiting factorβyour propertyβs net operating income must support the new mortgage payment. Weak cash flow limits equity access
- Cash-out refis pull more equity than rate-and-term refis, but require stronger DSCR and more careful underwriting
- The refinance process takes 6-12 weeks from application to funding. Plan ahead and gather documentation early
- Your current prepayment penalty must be justified by the savings on your new mortgage. Do the payback analysis first

Refinance
Replacing an existing mortgage with a new one, typically to access equity, get a better rate, or change terms. Investors commonly refinance to pull out capital for purchasing additional properties (cash-out refinance) while retaining ownership of the original property.
CMHC Insurance
Mortgage default insurance from Canada Mortgage and Housing Corporation. For 1-4 unit investment properties, investors must put 20%+ down (no insurance available). However, CMHC offers MLI Select for 5+ unit multifamily properties, and house hackers can access insured mortgages with 5-10% down.
LTV
Loan-to-Value ratio - the mortgage amount expressed as a percentage of the property's appraised value or purchase price (whichever is lower). An 80% LTV means you're borrowing 80% and putting 20% down. Lower LTV generally means better rates and terms.
DSCR
Debt Service Coverage Ratio - a metric that compares a property's net operating income to its mortgage payments. A DSCR of 1.25 means the property generates 25% more income than needed to cover the debt. Lenders typically require a minimum DSCR of 1.0 to 1.25 for investment property loans.
NOI
Net Operating Income - the total income a property generates minus all operating expenses, but before mortgage payments and income taxes. Calculated as gross rental income minus vacancies, property taxes, insurance, maintenance, and property management fees.
Equity
The difference between a property's current market value and the remaining mortgage balance. If your home is worth $500,000 and you owe $300,000, you have $200,000 in equity. Equity builds through mortgage payments, appreciation, and property improvements.
Cash Flow
The money left over after collecting rent and paying all expenses including mortgage, taxes, insurance, maintenance, and property management.
Multifamily
Properties with multiple dwelling units, from duplexes to large apartment buildings. Often offer better cash flow and economies of scale.
Amortization
The period over which a mortgage is scheduled to be fully paid off through regular payments of principal and interest. In Canada, common amortization periods are 25 or 30 years, though the mortgage term (when you renegotiate) is typically 1-5 years.
Mortgage Insurance Premium
The fee charged by CMHC or other insurers for mortgage default insurance on high-ratio mortgages. The premium is calculated as a percentage of the loan amount and can be added to the mortgage balance or paid upfront.
Appraisal
A professional assessment of a property's market value, required by lenders to ensure the property is worth the loan amount.
