What it costs to buy 7512 Ninth Line
At the asking price of $3,549,000, 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 | $3,549,000 |
|---|---|
| Ontario land transfer tax | $75,200 |
| First-time buyer refund, if you qualify | up to $4,000 |
| Minimum down payment | $709,800 |
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) | $16,946 a year, about $1,412 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.
How the asking price compares
TRREB's Market Watch recorded 108 detached sales in Markham in September 2026, at a median of $1,381,500 and an average of $1,534,139. This home is listed at $3,549,000, which is $2,167,500 above that median.
A city-wide median covers every size, age and neighbourhood, so it is a reference point and not a valuation of this home. Lot, size, condition and location all move the price. Our September 2026 market report and our Markham house prices page have the figures for each home type.
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 133.53 by 314 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 19 parking spaces.
- Get your financing in writing. A lender looks at the property tax as well as the price.
- See it in person. The listing has a virtual tour, but photos do not show noise, light at different hours or the condition of the roof, the basement and the yard.
Our page on buying a home in Markham sets out the steps in order. This is general information, not legal advice. Confirm the details with a lawyer.

Questions about Box Grove
Is highway noise a problem?
On the streets closest to Highway 407 it can be. This is worth checking in person, with the windows open, before you commit to a specific address.
What is left of the original hamlet?
A small cluster of older buildings and streets that predate the surrounding subdivisions. It gives the neighbourhood a name and a bit of character that the newer streets do not have.
Is it convenient for commuting?
For drivers heading east or west on Highway 407, extremely. For a downtown train commute it is one of the less convenient parts of Markham, since Markham GO is a drive north.
Is there shopping nearby?
The Boxgrove retail area covers day to day needs. Larger shopping is along Markham Road and Highway 7.
Does it suit first time buyers?
It can be, particularly for buyers who drive. Resale supply is thin, though. TRREB recorded 8 sales in all of Box Grove from January to March 2026, so be ready to wait for the right property.
