Thornhill (Markham) Home Values: What Sellers Need to Know
Quick answer: Thornhill's Markham side, east of Yonge Street, is the city's established west end, and TRREB tracks it as several distinct communities. In Q2 2026, detached medians ranged from $1,323,000 in Royal Orchard (16 sales) and $1,562,000 in Grandview (10 sales) to $2,850,000 in estate Bayview Glen (5 sales). Highways 407 and 404 and the Yonge and Bayview corridors are minutes away. Michael John Lau brings street-level, estate-calibre strategy to Thornhill sellers.

The Neighbourhood
Established Prestige, Several Markets
Thornhill's Markham side built its reputation slowly: decades of homes on mature streets, professionals drawn by the 407 and 404, and the Yonge and Bayview corridors threading it together. Thornhill spans two cities; Yonge Street divides the Markham side from the Vaughan side, with different tax rates and city services.
TRREB reports the Markham side as several communities, and they behave very differently, from established family streets in Royal Orchard to the estate lots of Bayview Glen.
- Mature, established streets
- Estate lots in Bayview Glen
- Highways 407 and 404 in minutes
- Yonge Street transit and the future subway
- Nearby schools such as St. Robert Catholic High School and its IB program
Yonge Street divides Thornhill between Markham (east) and Vaughan (west). Markham's 2026 tax rate, 0.722889%, is lower than Vaughan's 0.749217%. Listings do not always make the city clear, so check it for any address. See Markham vs Vaughan.
