## 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.

### Periodic rate
i = (1 + r/2)^(2/n) − 1. At 4.79% monthly, i = 0.395241%.

### Amount amortized
$600,000 − $120,000 = $480,000; insurance $0; total $480,000.

### Annuity
$2,734.60 monthly over 25 years. First period: $1,897.16 interest, $837.44 principal. Year-five balance $423,421.

## What this band means
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.

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.

## Local context
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.

- Quoted rate 5.79%: $3,011.41 (+$276.81 per payment)
- Quoted rate 3.79%: $2,470.55 (−$264.05 per payment)
- 30-year amortization: $2,501.85 (−$232.75 per payment)

## FAQs
### 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.
