What a $600,000 Ontario mortgage costs with twenty percent down

At this price in Ontario you can still insure if you put less than twenty percent down. This page does the other thing: it funds the conventional down payment so the loan is uninsured by choice, not because the price cap ejected you. That is a different borrower than the high-ratio starter. Equity is the scarce ingredient, not income. The payment should be read against the opportunity cost of locking $120,000 into the house instead of into a reserve, and against the fact that uninsured pricing at the same lender is often a few basis points less generous than the insured sheet. Ontario land transfer tax on this purchase is payable in cash at closing and is not inside the mortgage; it is a second cheque you write the same week.

Conventional principal, no insurance load

Twenty percent down takes this purchase off the high-ratio stack. The engine therefore adds no default-insurance premium, and the amount amortized equals price minus down payment. That is the whole mechanical difference from the starter pages. Semi-annual compounding still converts the quote; the annuity formula still runs over three hundred monthly periods. What you do not get, on a conventional file, is the thirty-year insured amortization that first-time and new-build insured purchases can use. The payment here is the uninsured, twenty-five-year version of a mid-market Ontario house, which is the version most repeat buyers actually sign.

What this band means

Monthly principal and interest is $2,734.60 on $480,000 with no insurance load. The first month sends $1,897.16 to interest and $837.44 to principal — still an interest-heavy split, but every dollar of that principal now builds your own equity rather than amortizing a premium. After five years the remaining balance is $423,421. Because you are uninsured, a later refinance that wants to pull equity is a conventional conversation from day one, and a thirty-year amortization is generally not on the menu unless a lender makes a special exception. The 4.79% pin is a contract quote, not a comparison of product types. If you instead bought this house with five or ten percent down, the engine would add a premium and the payment would rise even though the house did not. That is the fork this band exists to show: same address, two different loans. The scenario library owns the life-event version of that fork; this page owns the number.

This is the repeat-buyer, gift-augmented, or RRSP-HBP-plus-savings file in Ottawa, Barrie, or Kingston where twenty percent is painful but possible. Uninsured pricing at the same lender is a different sheet than the insured high-ratio column. A later refinance to pull equity starts conventional. The provincial levy at this price is a closing-week event the payment engine never sees. A gift letter and a conventional commitment letter are the paper this band actually produces. Do not import a thirty-year insured clock onto this conventional commitment, and do not pretend the first-time reform amortization applies here.

Sensitivity

Dropping the quote by a point does more for this conventional payment than stretching amortization, because there is no insured thirty-year option to grab. The next structural line is not insurance eligibility — you are already under the cap — it is whether you keep twenty percent down. Slip under that line and the premium returns and the payment is a different object.

Questions that only this band answers

Is a $600,000 Ontario home too expensive to insure?▾
No. Insurance eligibility is about the $1,500,000 cap and about loan-to-value, not about a six-hundred-thousand-dollar price. This page is uninsured because the down payment is twenty percent (80.0% LTV), not because insurers refused the property. A smaller down payment on the same price would be insurable and would add a premium to the loan.
Can I take a thirty-year amortization on this $600,000 conventional mortgage?▾
Generally no. The thirty-year amortization that arrived with the mid-December reforms is for insured first-time-buyer and newly built purchases. This example is conventional, so the engine holds 25 years. Stretching it would be a refinance conversation with a specific lender, not a default product feature.
Does Ontario land transfer tax get added to this $600,000 mortgage payment?▾
No. Land transfer tax is cash at closing. The $2,734.60 monthly figure is principal and interest only. Budget the provincial levy — and Toronto municipal tax if the property is inside the city — as a separate closing line. The land-transfer-tax examples on this site walk those brackets.
