What it costs to buy 21 Upper Duke Crescent 610B
At the asking price of $788,000, 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 | $788,000 |
|---|---|
| Ontario land transfer tax | $12,235 |
| First-time buyer refund, if you qualify | up to $4,000 |
| Minimum down payment | $53,800 |
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
| Maintenance fee | $835 a month |
|---|---|
| Property tax (2026) | $3,179 a year, about $265 a month |
| Fee and tax together | about $1,100 a month |
The listing says the fee includes heat, water, cac, common elements, building insurance and parking. That is before a mortgage payment, home insurance and any utilities the fee does not cover. A condo corporation sets its fees in each year's budget, so the amount can change. The status certificate shows the current fee, the budget behind it and the reserve fund.
How the asking price compares
TRREB's Market Watch recorded 55 condo apartment sales in Markham in September 2026, at a median of $535,000 and an average of $574,612. This home is listed at $788,000, which is $253,000 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. Size, floor, parking, condition and the building's finances 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
- Order the status certificate. An Ontario condo corporation must give one within 10 days of receiving the request and the fee, which is capped at $100. It shows the common expenses for this unit, any arrears, the budget, the reserve fund and any legal actions. Our guide explains what a status certificate tells you.
- Have a lawyer read it. The certificate comes with the declaration, by-laws and rules. Ask what they say about pets, renting the unit and renovations. The listing gives pets as "Yes-with Restrictions".
- Confirm the parking and locker. The listing shows 1 parking space and a locker (owned). Ask whether each is owned, exclusive use or rented. Get the unit numbers too.
- Get your financing in writing. A lender looks at the property tax and the monthly fee as well as the price.
- See it in person. photos do not show noise, light at different hours or the condition of the hallways and elevators.

Questions about Unionville
Is Unionville more expensive than the rest of Markham?
For houses, generally yes. From April to June 2026 the detached median in Unionville was about $1,625,000, among the highest of the neighbourhoods covered on this site (TRREB). The all property types median was much lower at $735,000, because 96 of the 159 sales were condo apartments. Buyers pay the house premium for the Main Street setting and the mature lots. Condos near Highway 7 compete directly with Downtown Markham.
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.
