Did OSFI Change the Rules for Rental Property Mortgages in 2026? What the Regulator Actually Said
No. OSFI published a written clarification confirming lenders can keep using rental income to underwrite investors with multiple properties, and that Guideline B-20 qualification did not change. What did change is a bank capital classification rule. Why that distinction decides whether your problem is a qualification problem or a lender problem, plus what the spread between two lenders is actually worth on the same file.

Ontario's HST Rebate on New Builds: Up to $130,000, and the Deadline That Actually Binds
A one-year window worth up to $130,000 on an eligible new build, open to move-up buyers, downsizers, and investors buying long-term residential rental, not just first-time buyers. The value tiers, why both halves are Ontario's own money rather than pending federal legislation, and why the agreement signature date between April 1 2026 and March 31 2027 is the only part you cannot get back.

Mortgage Renewal in Canada: Switch, Stay, or Restructure (and How to Tell the Difference)
Renewal is the one moment you can change lenders, products, or the whole structure with a zero prepayment penalty, and most borrowers sign the first number they are shown. What the November 2024 straight-switch rule change actually opened up, the single word that can break the exemption, and why whether your charge is standard or collateral turns a switch into a five-figure decision or a five-hundred-dollar one.

First-Time Home Buyer Programs in Canada: What Exists, and the Order to Use Them In
The list is not the strategy. These programs do three completely different jobs, and confusing them is how buyers arrive at closing short. Which ones are down payment, which are closing costs, which change what you qualify for, why a rebate is not a down payment, and the one deadline on this page you cannot recover once it passes.

Purchase Plus Improvements in Ontario: Financing the Suite Into the Purchase
The product that finances a renovation inside the purchase mortgage, at purchase mortgage terms, on day one. Why the improvement cap nearly doubles depending on which default insurer backs your file, the holdback mechanic that catches almost every first-time borrower, and how PPI sequences against the insured secondary suite refinance program you cannot use until you already own the home.

CMHC MLI Select: What It Is, Who Qualifies, and Why Most Investors Miss It
The 95% loan-to-value and 50-year amortization are real, and most investors asking about MLI Select cannot use it, because the program starts at five units. What the points system actually unlocks, the July 2025 premium restructuring that pushed a 70-point project from roughly 3.30% to 5.72%, and the February 2025 bundling rule that ended the single-family portfolio strategy.

Financing a Basement Apartment in Ontario
Why a basement apartment conversion is usually the easiest ADU to finance in Ontario. What makes a unit legal for appraisal and underwriting purposes, why lenders treat the work as an improvement rather than new construction, and how a HELOC or the CMHC Refinance Program typically covers the build without a full construction mortgage.

Financing a Coach House in Ontario: Why the Garage Underneath Changes the Math
A coach house sits over or attached to a garage, which means an engineer has to confirm the structure can carry a second story before financing even gets discussed. Why a new garage-plus-coach-house build finances like a detached garden suite while adding a story to an existing garage can be treated more like a renovation.

Using Home Equity to Build an ADU: How Much Is Actually Usable
Equity is appraised value minus what's owed, not purchase price minus what's owed, and lenders will only advance against 80% of it combined with the first mortgage. A worked example shows the gap between a stand-alone 65% HELOC and a combined 80% structure, and how the 2025 insured refinance program's as-complete valuation at 90% LTV can more than double what's available.

Financing a Prefab or Modular ADU in Ontario: Why the Payment Timeline Is Different
Prefab and modular garden suites are faster and often cheaper to build, but the financing structure is genuinely different from a site-built draw mortgage. Why factory deposits and progress payments don't line up with a lender's on-site inspection process, and how homeowners typically bridge the gap.

Financing an ADU When You're Self-Employed
Self-employed income gets averaged over two years of Notices of Assessment before a lender ever checks it against GDS/TDS ratios or the CMHC Refinance Program's underwriting, and that averaging can make a household look tighter than its real cash flow. Why the rental income offset matters even more on a tight self-employed file, and when an alt-A lender fits better.

The ADU Appraisal Process Explained: How a Garden Suite or Secondary Suite Gets Valued in Ontario
Why an ADU is harder to appraise than a resale home, how the as-complete appraisal works for construction and insured-refinance financing, and how the builder's cost breakdown and rental market rent survey feed that number. Covers appraisal timing against the construction draw schedule.

HELOC vs. Refinance vs. Construction Mortgage for an ADU: Which One Fits
Three ways to finance an ADU build, and they solve three different problems. A HELOC is interest-only on the drawn balance and leaves the first mortgage untouched. A refinance is one fixed payment from day one. A construction mortgage draws in stages tied to inspected milestones and takes six to ten weeks to first advance. A side-by-side comparison table plus which one fits which starting equity position.

Best Mortgage Options for Garden Suites in Ontario
A detached garden suite gets appraised closer to new construction than a basement conversion, and it needs its own hydro and water/sewer or septic hookup. Why a detached build needs the CMHC Refinance Program or a construction mortgage from the outset, and how to size the financing against your specific lot.

CMHC Programs for Secondary Suites: What's Actually Available Now
The Secondary Suite Loan Program (up to $80,000 at 2%) was cancelled in the 2025 federal budget and folded into the CMHC Refinance Program. Here's what happened to it, and the deep dive on the program that replaced it: 90% LTV against as-complete appraised value, up to $2 million, how CMHC mortgage insurance applies, and who it actually fits.

Common ADU Financing Mistakes to Avoid in Ontario
"Which product to use" is the second question. The first is whether a costly assumption is already baked into the plan. From overcounting projected rental income to assuming the CMHC loan covers a full detached build, these are the avoidable mistakes that turn a comfortable-looking ADU file into one that stalls mid-application or comes up short mid-construction.

Construction Mortgage Guide for ADUs and Garden Suites in Ontario
A HELOC covers most secondary suites, but a detached garden suite is a different financing problem: money released in stages tied to physical progress, not a lump sum at closing. How staged draws actually work, why lenders size the facility against as-complete value, and the three mistakes that stall a build mid-project.

Can Rental Income Help You Qualify? A Rental Income Qualification Guide
An already-tenanted suite with a signed lease is close to the easiest income a lender underwrites. Projected rent from a suite that doesn't exist yet is a different conversation entirely, with most A-lenders counting only 50% to 80% of it. How the offset actually works, what documentation lenders want, and why the standalone rental property case is far cleaner than the owner-occupied one.

Refinancing Your Mortgage in Canada: When the Math Works (and When It Doesn't)
A refinance is not a rate move, it is a restructuring move. Sometimes the restructuring is worth a five-figure penalty, and sometimes a quarter-point rate drop is not worth the paperwork. The honest answer comes down to a single break-even number, and most people never run it.

Financing a Rental Property in Ontario: DSCR, Down Payment, and What Lenders Actually Look At
Investment property mortgages aren't consumer mortgages. The underwriting math, the lender tiers, and the down payment rules all run differently. Why banks usually aren't the right lender, how DSCR actually qualifies the file, and the structural moves that separate the investors who scale from the ones who hit a wall at three properties.
