What it costs to buy 648 South Unionville Avenue
At the asking price of $1,199,800, 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 | $1,199,800 |
|---|---|
| Ontario land transfer tax | $20,471 |
| First-time buyer refund, if you qualify | up to $4,000 |
| Minimum down payment | $94,980 |
The down payment figure is the federal minimum: 5 percent of the first $500,000 and 10 percent of the rest. 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) | $4,850 a year, about $404 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 23.1 by 103 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 4 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 Unionville
Can you walk to the GO train from most of Unionville?
From the streets closest to Main Street and the Highway 7 corridor, yes. From the northern and eastern edges it is a short drive or a bus connection. Check the specific address before you count on walking.
What kind of homes are on Main Street itself?
Mostly nineteenth and early twentieth century houses, some converted to shops and restaurants. They rarely come up for sale, they often carry heritage considerations and they attract a very particular buyer.
Is Unionville a good place to buy a first home?
It can be, but usually as a condo or an older townhome rather than a house. If your budget is stretched, neighbouring Wismer or Greensborough will buy you more square footage for the same money.
How is parking and traffic around Main Street?
Main Street is busy on summer weekends and during festivals. Residents on the immediate side streets deal with overflow parking several times a year. It is a real trade-off and worth driving on a Saturday before you commit.
Does Unionville flood?
Parts of the area sit near the Rouge tributaries and Toogood Pond. Low lying lots and older basements deserve a close look. Ask for the insurance history and have the grading assessed.
