The Costs of Homeownership
Down Payment
Your down payment is your initial investment when purchasing a home.
Minimum down payment requirements in Canada:
Homes under $500,000: minimum 5%
Homes between $500,000 and $999,999:
5% on the first $500,000
10% on the remainder
Homes $1 million or more: minimum 20%
A larger down payment reduces your mortgage amount, may improve your interest rate, and lowers mortgage insurance costs. If your down payment is under 20%, mortgage default insurance is required and added to your mortgage.
Mortgage
Your mortgage payment typically includes principal and interest. The amount depends on:
Loan amount
Interest rate
Amortization period
Payment frequency
If you choose a variable rate or when a fixed term expires, your payments may increase. Building a buffer into your budget is recommended.
Property Taxes
Property taxes fund municipal services and are based on assessed value and local tax rates.
Rates vary across Canada, generally between 0.5% and 1.5% annually.
Some lenders collect property taxes with your mortgage payment.
If not included, you must budget separately.
Home Insurance
Home insurance is usually required by lenders and protects:
The structure of the home
Personal belongings
Liability coverage
Temporary living expenses if repairs are needed
Costs vary based on location, home value, construction, and coverage level.
Maintenance
A common guideline is to budget 1 to 3 percent of the home’s value annually.
Maintenance costs can include:
Roof replacement
Furnace or HVAC repairs
Plumbing or electrical work
Foundation repairs
Newer homes often require less early maintenance, while older homes may require more immediate repairs.
Utilities and Services
Monthly utilities may include:
Electricity
Heating
Water and sewage
Additional costs can include:
Internet and phone
Garbage and recycling
Security systems
Lawn care and snow removal
These expenses can add hundreds of dollars per month.
Extra Fees
If purchasing a condo or property with a homeowners association:
Condo fees typically range from $0.50 to $1.00 per square foot monthly
Fees often cover insurance, maintenance, shared utilities, and reserve funds
Fees can increase over time, especially in older buildings

Debt
Existing debt reduces affordability through the TDS ratio.
Paying down high-interest debt before buying often improves borrowing capacity.
