What it costs to buy 30 Thornlea Road
At the asking price of $5,488,000, a buyer in Markham pays Ontario land transfer tax on closing. The City of Toronto is the Ontario municipality that charges a municipal land transfer tax of its own, so there is no second tax here.
| Asking price | $5,488,000 |
|---|---|
| Ontario land transfer tax | $123,675 |
| First-time buyer refund, if you qualify | up to $4,000 |
| Minimum down payment | $1,097,600 |
The down payment figure is the federal minimum: 20 percent of the price, which applies at $1.5 million or more. A lender can ask for more. These figures use the asking price, so they change if you pay more or less. The tax is worked out at the published rates for a home with one or two single family residences and your lawyer confirms the final amount. Legal fees, title insurance and adjustments are extra: our closing costs guide lists them. This is general information, not legal or tax advice. Confirm the figures with a lawyer or accountant. You can change the price in our land transfer tax calculator and our mortgage calculator.
What it costs to own each month
| Property tax (2025) | $21,500 a year, about $1,792 a month |

That is before a mortgage payment, home insurance and utilities. These are the figures on the listing, so check the current tax bill before you rely on them.

What to check before you make an offer
- Book a home inspection. An inspection looks at the parts of a house you cannot judge at a showing. Our guide explains what a home inspection covers and misses.
- Ask for the survey. The listing gives the lot as 102.28 by 165.13 feet. If the seller has a survey, check the lot lines, fences and any easements against it.
- Confirm what stays. Have the appliances, fixtures and any rented equipment written into the offer.
- Confirm the parking. The listing shows 11 parking spaces.
- Get your financing in writing. A lender looks at the property tax as well as the price.
- See it in person. photos do not show noise, light at different hours or the condition of the roof, the basement and the yard.

Questions about Thornhill
Is Thornhill the same as Markham?
No. Thornhill is a community that sits in two cities. The part east of Yonge Street is in the City of Markham and the part west of Yonge Street is in the City of Vaughan. This guide covers the Markham side.
Which side of Thornhill is Markham?
Yonge Street is the dividing line. East of Yonge is Markham, west is Vaughan. Two houses facing each other across Yonge sit in different municipalities, with different taxes and different city services.
How old is the housing?
Much of it dates from the 1950s through the 1980s, which makes this the most mature housing stock in Markham. Expect older systems and budget for them.
Is there a lot of rebuilding?
Yes. Large mature lots close to Toronto attract builders and several pockets have seen steady teardown and rebuild activity for years.
How is transit?
Better than most of Markham. Viva and YRT run on Yonge Street and Highway 7 and TTC connections at Steeles put the subway within reach without a car.
Who is buying here?
A mix. Downsizers who have been in the area for decades, families drawn by proximity to Toronto and builders. That mix keeps competition for good lots high.
