Property tax and the buy vs rent decision

How property tax enters the comparison

Owners pay property tax directly to the municipality, usually in instalments or through the mortgage lender. Renters do not receive a bill, but landlords factor property tax into the rent they charge, so renters pay it indirectly. The model counts it as a cost on the owner’s side only because the renter’s version is already inside the rent figure.

Mortgage interest and property tax on a principal residence are not tax-deductible in Canada, so there is no offset on the owner’s tax return. The full amount is a cost.

Property tax as a percentage of value

The engine models property tax as a percentage of the home’s value each year. The default is 0.65%, meaning $3,900 a year, or $325 a month, on a $600,000 home. Because the base is the home’s value, the tax grows when the home appreciates.

That link shows up in the numbers. Over ten years the engine adds up about $42,704 of property tax when the home appreciates at 2% a year, $45,752 at 3.5% and $49,054 at 5%. Higher appreciation helps the owner’s equity but also raises the tax bill, so the benefit is slightly smaller than it looks.

The percentage is an approximation. Actual bills depend on a municipality’s tax rate and on the assessed value, which may be different from market value and may be updated on a different schedule. Rules for assessment and for how rate changes are phased in differ by province and municipality, so ask your municipality or check a recent bill for a comparable home.

A worked example with four tax rates

Suppose a $600,000 home with 20% down, a 4.5% rate, rent of $2,300 a month and a ten-year hold, with all other inputs at the calculator defaults. Only the property tax rate changes. These rates are illustrations, not a forecast for any municipality.

Why the same price can mean a different tax bill

Two homes with the same market price can carry very different taxes. Rates vary by municipality and by how the property is classified and assessed, so a home just across a municipal boundary can carry a noticeably different bill.

When you compare cities, look at a recent tax bill for a home like the one you would buy rather than relying on a province-wide average. The city pages under buy vs rent in your city show how the tool is set up for particular places, and each lets you enter your own inputs.

Condos and property tax

Condominium owners are usually billed property tax on their own unit, separate from the monthly condo fee. The fee covers shared costs such as the building’s insurance and reserve fund, but check what your fee includes. See condo fees and special assessments.

A condo with a low property tax but a high fee can cost about the same as a house with a higher property tax and no fee. Compare totals, not individual lines.

Steps for your own comparison

Start with a real property tax figure for a similar home, divide it by the purchase price to get a percentage, and enter that in the true cost of owning tool. Then run a few alternative percentages to see how sensitive the result is.

Property tax is only one line. Put it alongside maintenance, insurance and the others in hidden costs of owning before you decide.
