CMHC MLI Select for Existing Properties: The Complete Guide
CMHC MLI Select is mortgage-loan insurance that can support the purchase or refinance of an existing rental building of 5+ units at up to 85% loan-to-value with 50 points, rising to 95% LTV at 70+ points, with amortizations extending from 40 years up to 50 years at the 100-point tier and a DCR floor of 1.10 — if the property commits to affordability, energy improvement, or accessibility outcomes. The program is a widely used mortgage-loan-insurance tool for owners of existing Canadian multifamily buildings, and its existing-property rules differ substantially from the new-construction rules most articles describe.
All thresholds below were verified against CMHC's published MLI Select criteria on August 9, 2026. CMHC revises the program; verify current criteria before designing to them. MBL Developments is an independent company — this guide is not affiliated with, reviewed by, or endorsed by CMHC.
How the process actually works
You do not "apply to CMHC." The sequence runs: borrower → mortgage professional → CMHC-approved lender → CMHC. The approved lender underwrites your file first, on its own credit standards, and then submits to CMHC for insurance. This matters for how you prepare: your file must survive two reviews, and the lender's questions come before CMHC ever sees the application. Preparing an organized preliminary file — normalized rent roll, rebuilt operating statement, defensible NOI, a named points pathway — is the borrower's leverage in that chain.
The existing-property point pathways
Points come from three categories. 50 points unlocks the program; 70 and 100 unlock more.
Affordability (existing properties)
| Points | Requirement |
|---|---|
| 50 | 40% of units at rents ≤ 30% of median renter income |
| 70 | 60% of units at rents ≤ 30% of median renter income |
| 100 | 80% of units at rents ≤ 30% of median renter income |
Minimum 10-year commitment; a 20-year commitment adds 30 points. Note how much deeper these run than new construction (which starts at just 10% of units): on an existing market-rent building, the affordability path usually means committing a large share of the roll to below-market rents. For many owners that math fails — which is why the energy path matters.
Energy efficiency (existing properties)
Measured as reduction versus the building's current performance — not versus a construction code baseline:
| Points | Required reduction |
|---|---|
| 20 | 15% |
| 35 | 25% |
| 50 | 40% |
A retrofit that cuts consumption 25% — envelope work, heat pumps, controls — earns 35 points on its own. This is the realistic pathway for most market-rent buildings, and it needs an energy professional to model and attest.
Accessibility
20 points for a minimum 15% accessible units (CSA B651:23), full universal design at the 60–79% Rick Hansen band, or equivalent; 30 points for the deeper combinations (100% universal design or Rick Hansen Gold).
What the points unlock (existing properties)
| Threshold | Maximum LTV | Amortization | Other |
|---|---|---|---|
| 50+ | 85% | up to 40 years | DCR floor 1.10, recourse, discretionary reserves |
| 70+ | 95% | up to 45 years | — |
| 100+ | as above | up to 50 years | limited-recourse option |
Two practical readings. First, an 85% LTV refinance at 50 points is the accessible tier — a 25% energy reduction (35 pts) plus modest affordability or accessibility gets there without transforming the rent roll. Second, 95% LTV requires 70+ points, and on the affordability path that means 60% of units at the threshold — deep. Run the number honestly before a broker runs it optimistically.
Official rule vs. our interpretation
Everything in the tables above is CMHC's published criteria. What follows is MBL's interpretation from preparing files: the binding constraint on existing-property loans is usually DCR at 1.10, not LTV — a building's normalized NOI sizes the loan before the LTV ceiling does. That is why rebuilding NOI from source documents (leases, trailing statements, tax bills — not the offering memorandum) is where an application is won or lost. Premium schedules also improve with points, which changes the all-in cost of debt; your lender quotes the exact schedule.
Where to go from here
If you are evaluating an existing 5+ unit property, our Canada-wide course CMHC MLI Select for Existing Multifamily teaches the full underwriting sequence — evidence register, normalized NOI, valuation, LTV/DCR sizing, and the points pathway — with deterministic calculations you can check yourself. For a fast first look, the free multifamily quick screen is an educational calculator that illustrates how LTV and DCR each cap a loan. If your project is a new Toronto sixplex rather than an existing building, the rules differ — read the Toronto sixplex financing guide.
