Here’s something that drives me crazy. CMHC has been offering real, tangible financial incentives to investors who build or retrofit energy-efficient rental properties — and most investors have no idea these programs exist.
We’re talking about mortgage insurance premium refunds, lower rates, and longer amortization periods. Real money that goes straight to your bottom line. And the programs keep getting better because the federal government is pushing hard on housing and climate goals simultaneously.
Let me break down exactly how CMHC’s green financing programs work and how you can use them on your next deal.
CMHC MLI Select: The Program You Need to Know
MLI Select is CMHC’s flagship program for multi-unit residential properties (5+ units). It replaced the old CMHC Green Home program and rolled several incentives into one framework.
The program works on a points system. You earn points across three categories:
- Energy Efficiency — reducing energy consumption and greenhouse gas emissions
- Accessibility — building accessible units
- Affordability — providing below-market rents
The more points you earn, the better your financing terms. And here’s what matters to you as an investor: the energy efficiency stream alone can qualify you for significant benefits. For a detailed comparison of MLI Select to standard CMHC multifamily insurance, see our MLI Select versus Standard comparison guide.
What You Get
Depending on how many points you accumulate, MLI Select offers:
- Mortgage insurance premium refunds up to 25% of the premium paid
- Extended amortization up to 50 years (yes, 50) on insured loans
- Lower premium rates compared to standard CMHC multi-unit insurance
- Higher loan-to-value ratios — up to 95% for projects meeting affordability criteria
Let me put that in dollar terms. On a $2 million multifamily purchase with CMHC insurance, your premium might be $80,000 to $90,000. A 25% refund puts $20,000 to $22,500 back in your pocket. The extended amortization reduces your monthly mortgage payment, improving cash flow from day one.
These aren’t theoretical benefits. They’re available right now on qualifying properties.
How the Points System Works
For the energy efficiency stream specifically, CMHC awards points based on your building’s energy performance relative to a baseline. The key metrics are:
- Energy intensity (gigajoules per square metre per year)
- Greenhouse gas intensity (kilograms CO2 per square metre per year)
For new construction, you earn points by beating the National Energy Code for Buildings (NECB) by specified percentages. For existing buildings, you earn points by demonstrating improvement from a retrofit or by meeting specific energy performance thresholds.
Here’s the simplified version:
| Achievement Level | Energy Reduction | Typical Points |
|---|---|---|
| Minimum threshold | 10-15% below NECB | Low |
| Mid-range | 25-40% below NECB | Medium |
| High performance | 40%+ below NECB or net-zero ready | High |
Higher points mean better financing terms. The math gets detailed, but the principle is straightforward: the more efficient your building, the better your deal.
CMHC Premium Refunds: How They Actually Work
Let’s get specific about the premium refund because it’s the most immediately impactful benefit.
When you get CMHC mortgage insurance on a multi-unit property, you pay a premium based on your loan-to-value ratio. Standard premiums range from about 1.5% to 4.5% of the loan amount. On a $2 million mortgage, that’s $30,000 to $90,000.
With MLI Select energy efficiency points, CMHC refunds a portion of that premium. The refund percentage scales with your point total:
- Lower tier: Up to 10% premium refund
- Mid tier: Up to 15% premium refund
- Top tier: Up to 25% premium refund
The refund is typically issued after you demonstrate compliance — meaning you’ve completed your retrofit and had it verified, or your new construction meets the stated performance level.
Real example: You buy a 12-unit apartment building for $3 million with 15% down. Your CMHC-insured mortgage is $2.55 million. Standard premium at 3.75% is $95,625. With a mid-tier energy efficiency qualification, you get a 15% refund — that’s $14,344 back.
That $14,344 is money you can reinvest, use toward your next property’s down payment, or put toward additional energy upgrades.
EnerGuide Requirements: What You Need to Prove
CMHC doesn’t just take your word for it that your building is energy efficient. You need documentation, and the standard is based on Natural Resources Canada’s EnerGuide rating system or equivalent energy modelling.
For Existing Buildings (Retrofits)
You’ll need:
-
Pre-retrofit energy assessment — An EnerGuide evaluation or energy audit showing your building’s current performance. Cost: $500 to $2,000 depending on building size.
-
Retrofit plan — Detailed scope of energy upgrades you’ll complete. This needs to show projected energy savings.
-
Post-retrofit verification — After completing upgrades, another assessment confirming the improvements were achieved. Cost: $500 to $2,000.
The total assessment cost of $1,000 to $4,000 is small compared to the premium refund you’ll receive. Think of it as the application fee for getting thousands back.
For New Construction
New builds need to demonstrate compliance through energy modelling during the design phase and verification upon completion. Your architect or builder should be working with an energy modelling consultant. Common pathways include:
- NECB compliance with documented percentage improvement
- ENERGY STAR for Multi-Family certification
- Passive House or similar high-performance standards
Most builders targeting CMHC financing already factor this into their process. If yours doesn’t, that’s a red flag — find a builder who does.
Certified Energy Advisors
You’ll need a certified energy advisor (CEA) or equivalent professional. They’re listed on Natural Resources Canada’s website. In most major Canadian markets, you’ll have several to choose from. Book early — demand for these services has increased significantly.
Qualifying Retrofit Scope: What Upgrades Count
Not every upgrade earns you CMHC points. The program focuses on upgrades that measurably reduce energy consumption and GHG emissions. Here’s what typically qualifies:
High-Impact Upgrades
- Building envelope improvements — insulation, air sealing, window upgrades
- HVAC system replacements — high-efficiency furnaces, boilers, heat pumps
- Domestic hot water systems — heat pump water heaters, solar thermal
- Ventilation systems — heat recovery ventilators (HRVs) or energy recovery ventilators (ERVs)
Moderate-Impact Upgrades
- Lighting upgrades — LED conversion throughout common areas and units
- Building automation systems — smart thermostats, automated controls
- Low-flow water fixtures — reduces hot water energy demand
What Doesn’t Count
- Cosmetic renovations (paint, flooring, countertops)
- Appliance upgrades that aren’t energy-related
- Landscaping
- General maintenance
The key is that your energy advisor’s assessment needs to show measurable improvement. A mix of envelope upgrades plus a heating system replacement typically gets you into the mid to high point range.
Combining MLI Select With Other CMHC Programs
This is where it gets really interesting. CMHC programs can often be combined, and that stacking effect can make deals work that otherwise wouldn’t.
MLI Select + Rental Construction Financing Initiative (RCFI)
If you’re building new rental housing, CMHC’s construction programs provide low-cost construction loans and favourable take-out financing. For a deep dive into construction financing coordination with permanent takeout, review our CMHC Apartment Construction Loan Program guide. Combined with MLI Select energy efficiency points, you can access:
- Construction financing at competitive rates
- Take-out financing with extended amortization up to 50 years
- Premium refunds on the permanent financing
- Higher LTV ratios
For a new 20-unit build at $6 million, the combined benefits could mean $30,000 to $50,000 in premium savings plus significantly improved monthly cash flow from the extended amortization.
MLI Select + Affordable Housing Programs
If you’re willing to designate some units as affordable (rents at or below 30% of median household income for the area), you earn points in both the affordability and energy efficiency categories. This gets you to the top tier of benefits faster.
For investors in markets where affordable rents still provide decent returns (think secondary and tertiary Canadian cities), this combination is powerful. You might get 50-year amortization, a 25% premium refund, and higher LTV — all while running a profitable building.
MLI Select + Provincial Rebates
CMHC’s program doesn’t prevent you from also claiming provincial energy rebates. So your heat pump upgrade might qualify for:
- A $5,000 provincial rebate (reducing your capital outlay)
- CMHC MLI Select points (earning you premium refunds and better terms)
- CCA depreciation (reducing your tax burden)
Triple-dipping is perfectly legal and encouraged.
The Application Process: Step by Step
Here’s how to actually get this done:
Step 1: Determine eligibility. MLI Select applies to multi-unit residential properties (5+ units). If you’re buying or building a qualifying property, you’re potentially eligible.
Step 2: Get an energy assessment. Hire a certified energy advisor to evaluate your property (existing) or review your building plans (new construction). Budget $500 to $2,000.
Step 3: Develop your upgrade plan. Work with your energy advisor to identify which upgrades will earn you the most points for the least cost.
Step 4: Apply through your lender. CMHC mortgage insurance is applied for through your mortgage broker and lender. They submit the MLI Select application on your behalf. This is where having a broker who understands these programs matters — a lot.
Step 5: Complete the work. Do the retrofits or build to spec. Keep all receipts and documentation.
Step 6: Verify and claim. Get your post-retrofit assessment, submit documentation to CMHC through your lender, and receive your premium refund.
The whole process typically takes 3 to 6 months for retrofits or aligns with your construction timeline for new builds. For retrofits specifically, the premium refund can work well alongside a refinance—see our guide on refinancing apartment buildings with CMHC for the broader refinance context.
Is It Worth the Effort?
Ready to explore your financing options? Book a free strategy call with LendCity and let our team help you find the right path forward.
Let me give you the honest answer. For a 5-unit property, the premium refund alone might be $5,000 to $10,000. Add in the energy cost savings from the upgrades themselves, and you’re looking at a meaningful improvement to your returns.
For a 20+ unit building, the numbers get very compelling. Premium refunds of $20,000+, annual energy savings of $10,000+, and the extended amortization benefit can add up to six-figure improvements over the hold period. These stacked benefits amplify what’s outlined in our comprehensive multifamily financing guide, where combining multiple programs creates superior project economics.
The effort involved is real — you need assessments, documentation, and the right professional team. But for anyone buying or building multi-unit residential in Canada, leaving these incentives on the table is leaving money behind.
Work with a mortgage broker who knows these programs inside and out. The difference between a broker who’s done 50 CMHC multi-unit deals and one who’s done 2 is enormous when it comes to structuring your deal to capture every available benefit. For new construction projects, this broker expertise becomes even more critical—see our new construction developer guide for what to expect in that process.

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.
Down Payment
The upfront cash payment when purchasing a property. For 1-4 unit investment properties, minimum 20% down is required. 5+ unit multifamily can use CMHC MLI Select with lower down payments, and house hackers can put as little as 5% down on owner-occupied 2-4 plexes.
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.
High-Ratio Mortgage
A mortgage with less than 20% down, requiring default insurance. Not available for 1-4 unit investment properties in Canada. However, 5+ unit multifamily can access CMHC MLI Select, and house hackers in owner-occupied 2-4 plexes can use insured financing.
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.
CMHC MLI Select
A CMHC program offering reduced mortgage insurance premiums and extended amortization (up to 50 years) for multifamily properties with 5+ units that meet energy efficiency or accessibility standards. Popular among investors scaling into larger apartment buildings.
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.
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.
Mortgage Broker
A licensed professional who shops multiple lenders to find the best mortgage rates and terms for borrowers. Unlike banks, brokers have access to dozens of lending options.
HVAC
Heating, Ventilation, and Air Conditioning systems that control temperature and air quality in buildings. HVAC is often one of the largest energy expenses in rental properties, and upgrading to high-efficiency systems can significantly reduce operating costs and increase NOI.
Energy Efficiency
The effectiveness with which a property uses energy for heating, cooling, lighting, and other functions. Energy-efficient upgrades to rental properties reduce operating costs, increase NOI, and can add significant property value while qualifying for government rebates.
Capital Cost Allowance
The Canadian tax deduction that allows property owners to write off the depreciation of a building over time, reducing taxable rental income. CCA cannot be used to create a rental loss and must be recaptured upon sale of the property.
Construction Loan
Short-term financing used to fund building a new property. Funds are released in stages (draws) as construction milestones are completed, and interest is charged only on drawn amounts. Construction loans typically convert to permanent financing upon project completion.
Takeout Financing
Permanent long-term mortgage financing that replaces a short-term construction loan after a development project is completed and stabilized. Securing a takeout commitment before construction begins reduces project risk.
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.
Depreciation
An accounting method that allocates the cost of a building over its useful life as a tax deduction. In US real estate, depreciation reduces taxable rental income. The Canadian equivalent is Capital Cost Allowance (CCA).
Heat Pump
An electric heating and cooling system that transfers heat between indoor and outdoor air. Cold-climate heat pumps eliminate carbon tax exposure on heating costs and can significantly reduce operating expenses compared to natural gas furnaces.
Insulation
Material installed in walls, attics, and floors to resist heat flow, measured by R-value. Upgrading insulation in older properties reduces heating and cooling costs, improves tenant comfort, and can qualify for government energy rebates.
