Insured vs Insurable vs Uninsured Mortgage

Insured: mortgage default insurance is actually in force. Insurable: the mortgage has characteristics that may qualify for insurance/funding treatment, even if the borrower is not paying a high-ratio premium. Uninsured: no mortgage default insurance covers the lender’s mortgage loss.

“Conventional” is separate: it generally describes a mortgage at 80% LTV or less, and a conventional mortgage can fall into any of the three insurance statuses.

The exact product still depends on the lender and insurer, but the following matrix captures the structural differences.

First ask whether the mortgage is above 80% LTV. If yes, a standard eligible purchase through a federally regulated lender will generally require transactional insurance. If LTV is 80% or less, ask whether the purpose, amortization, property value/type and occupancy fit current insurer criteria. If they do, the mortgage may be insurable and may be insured by the lender. If they do not—or the lender funds it without insurance—it may be uninsured.

Then check for specialty programs. An insured secondary-suite refinance is a good example of why a decision tree needs an exception branch rather than an absolute “refinance = uninsured” rule.

The base mortgage is $810,000, or 90% LTV. If the borrower/property qualify under a standard high-ratio purchase program, the mortgage is insured and the borrower normally pays the applicable transactional insurance premium. Lender and insurer approval are both required.

The borrower should compare the premium, payment and liquidity preserved by using less than 20% down.

The mortgage is 80% LTV and therefore conventional/low-ratio. It has common insurable characteristics under current insurer programs, subject to borrower, property and lender criteria. The lender may obtain insurance itself or simply price/fund it as an insurable mortgage.

The borrower normally does not pay the standard high-ratio premium, but insurance status on the lender’s side can still matter.

The mortgage is conventional by LTV, but current public Sagen and Canada Guaranty programs use a below-$1-million property-value ceiling for many low-ratio purchase-insurance paths. That can make a $1.2 million conventional mortgage uninsured under the lender’s available funding/insurance options even though the borrower has 20% equity.

This is the clearest example of why “20% down = insurable” is not a reliable universal rule.

The homeowner has substantial equity, so the mortgage is conventional by leverage. But an ordinary cash-out refinance commonly sits outside standard mortgage-insurance eligibility, making it uninsured. Low LTV does not automatically restore insurability when the transaction purpose changes.

If the refinance is specifically for an eligible secondary-suite project, a current insured refinance program may create a different result.

Insured and insurable mortgages can sometimes price lower because insurance/funding reduces lender risk. Uninsured mortgages can sometimes offer features that the insured system does not permit. Neither statement makes one category universally better.

Likewise, insured does not mean weak borrower and uninsured does not mean strong borrower. A 95% insured first-time buyer and a 50% LTV uninsured refinance simply solve different financing problems under different risk structures.

For an insured mortgage, include the borrower-paid premium, tax and larger financed balance. For an insurable mortgage, pay attention to the rate/product features that depend on keeping insurer-eligible characteristics. For an uninsured mortgage, compare any pricing premium against the extra flexibility the product provides.

Across all three, compare payment, prepayment privileges, penalty exposure, portability, amortization and expected balance at the time you are most likely to renew, refinance or sell.

Adding equity, increasing amortization, taking cash out, changing occupancy, moving to a more expensive property or selecting a specialty program can all change the insurance classification. A mortgage that started insured can later be refinanced into an uninsured product; an existing insured mortgage may also preserve insurance through portability under defined rules.

So insurance status should be treated as a property of the current transaction and product, not a permanent label attached to the borrower.

Use Mortgage Default Insurance and Insured Mortgage Premiums if insurance is in force. Use Insurable Mortgages if insurer eligibility is affecting a low-ratio quote. Use Uninsured Mortgages if the desired purpose, value or amortization sits outside insurance.
