A three-bedroom home is Coming Soon to MLS® in Ingersoll this Friday for $500,000.
But a listing price is only one piece of the home-buying puzzle. What might purchasing a $500,000 home actually look like once we account for the down payment, mortgage default insurance and estimated monthly payment?
Let’s do the mortgage math.
Our Sample Calculation
To keep the comparison consistent, the estimates below use:
A $500,000 purchase price
A sample interest rate of 4.49%
A five-year fixed mortgage
A 25-year amortization
Monthly mortgage payments
The 4.49% rate is being used strictly as an educational example. Available rates and mortgage products depend on the borrower, property, lender and date of application.
Option One: A 5% Down Payment
For a home priced at $500,000, the minimum down payment is 5%, subject to lender and mortgage-insurer approval.
Purchase price: $500,000
Down payment: $25,000
Base mortgage: $475,000
Estimated mortgage-insurance premium: $19,000
Estimated total mortgage: $494,000
Estimated monthly payment: $2,731
Because the down payment is below 20%, mortgage default insurance would normally be required. The premium protects the lender—not the borrower—and is generally added to the mortgage.
In Ontario, provincial sales tax on the insurance premium cannot be added to the mortgage. In this example, the estimated tax would be approximately $1,520 and would need to be paid as part of the buyer’s closing costs.
Option Two: A 10% Down Payment
A larger down payment reduces both the amount borrowed and the applicable mortgage-insurance premium.
Purchase price: $500,000
Down payment: $50,000
Base mortgage: $450,000
Estimated mortgage-insurance premium: $13,950
Estimated total mortgage: $463,950
Estimated monthly payment: $2,565
The estimated monthly payment is approximately $166 lower than with a 5% down payment.
The estimated Ontario sales tax on the insurance premium would be approximately $1,116, payable at closing.
Option Three: A 20% Down Payment
With 20% down, mortgage default insurance is generally not required.
Purchase price: $500,000
Down payment: $100,000
Estimated mortgage amount: $400,000
Mortgage-insurance premium: $0
Estimated monthly payment: $2,212
This option produces the lowest estimated monthly mortgage payment, but it also requires significantly more money upfront.
Comparing the Three Options
A larger down payment can reduce your mortgage and monthly payment, but putting every available dollar into the down payment is not always the best strategy.
Buyers should also retain enough money for closing costs, moving expenses, immediate repairs and a comfortable emergency fund.
What About Land Transfer Tax?
The regular Ontario land transfer tax on a $500,000 purchase would be approximately $6,475.
An eligible first-time homebuyer may qualify for an Ontario land transfer tax refund of up to $4,000. If the full refund applies, the remaining provincial land transfer tax would be approximately $2,475.
Eligibility requirements apply, and your lawyer will confirm the actual tax and any available refund.
The Mortgage Payment Is Not the Entire Housing Payment
Your monthly ownership budget may also need to include:
Property taxes
Home insurance
Heating and utilities
Maintenance and repairs
Any applicable condominium or association fees
Existing loan, credit card or vehicle payments
This is why mortgage qualification and comfortable affordability are not necessarily the same number.
A lender may approve a particular purchase price, but your personal budget determines whether the resulting payment feels manageable.
How Much Income Would You Need?
There is no single income requirement that applies to every buyer.
Qualification depends on the interest rate used for the mortgage stress test, property taxes, heating costs, down payment, credit history and the applicant’s existing monthly debt obligations.
Two households earning the same income can qualify for very different mortgage amounts because their debts, credit profiles and down payments are different.
The most useful calculation is not, “What is the largest mortgage I can obtain?”
It is, “What purchase price gives me a payment I can comfortably carry while still living my life?”
