Markham’s 2026 real estate market is not a single market. It is a collection of micro-markets performing completely differently from each other — in some cases, in opposite directions simultaneously. The most striking divergence is between the semi-detached home market and the condo apartment market. Understanding this divergence, and knowing how to position yourself in each segment, is the defining buyer and investor intelligence opportunity in Markham right now.

Michael John Lau, top real estate agent in Markham Ontario, is tracking both segments daily. Here is the complete picture.

The Semi-Detached Data — What Is Actually Happening

In February 2026, Markham’s semi-detached segment averaged $1,104,220. The semi-detached market had a 107% sale-to-list price ratio and an 8-day median days on market — the tightest supply and strongest buyer competition of any property type in Markham’s 2026 market. In a city where the overall average is 97% of list price and 33 days on market, Markham’s semi-detached homes are performing in a completely different market environment from the headline figures.

239 Fred McLaren Boulevard sold for $1,150,000 — $162,000 above asking. 11 Stella Drive sold for $983,300 — $95,000 above asking. These are not anomalies. They are consistent expressions of the supply-demand dynamics in Markham’s semi-detached market.

Why Semi-Detached Homes Are Outperforming in Markham

School catchment access at an accessible price. Wismer Commons semi-detached homes at $950,000 to $1,100,000 put buyers in the Bur Oak Secondary School catchment — the same catchment that commands $1,300,000 to $1,500,000 for detached homes. The school quality is identical; the property type is different. Buyers who specifically need Bur Oak catchment access but cannot reach the detached tier compete intensely for every semi-detached listing in Wismer, creating the 107% sale-to-list dynamics.

Freehold ownership without the full detached premium. The “missing middle” is the star performer of 2026, with semi-detached homes offering the perfect balance between space and price point for growing families — at a $200,000 to $400,000 discount to comparable detached.

Limited supply. New semi-detached homes are not being built at meaningful scale in established Markham communities. The semi-detached inventory in Wismer Commons, Greensborough, Cornell, and Raymerville is finite. When more buyers want a specific product than that product can be produced in, prices rise and competition intensifies.

The Condo Data — What Is Actually Happening There

Condo apartments in the GTA averaged $639,468 in May 2026 — down 6.4% year-over-year. Markham’s condo segment has significantly extended days-on-market relative to the semi-detached segment. Buyers have substantial choice and strong negotiating leverage. The condo market’s challenges are well-documented: investor retreat, immigration moderation reducing rental demand, elevated new completions adding supply, and a buyer pool that is more price-sensitive than the freehold market’s end-user cohort.

How to Play Both Markets — The Strategy Guide

For buyers of semi-detached homes in Markham: Move fast and come prepared. The 8-day median DOM means that well-priced semi-detached homes in school catchment communities receive multiple offers within a week of listing. Have your mortgage pre-approval fully underwritten — not a general pre-qualification. Have your agent’s CMA completed before a listing hits the market. In this segment, the buyer who hesitates loses. Conditional offers are still acceptable — but keep condition periods as short as practical.

For buyers of Markham condos: You have leverage. Use it systematically. The 97% to 98% sale-to-list ratio applies to condos — and in specific buildings with elevated supply, the effective rate is lower than the market average. Include a home inspection condition. Include a status certificate review condition for any condo corporation. Take time to compare multiple units in multiple buildings. Negotiate on price, inclusions, and in the pre-construction market specifically, development charge caps and assignment rights.

For investors looking at both: The semi-detached market offers near-term appreciation potential and a rental income profile from secondary suites that is structurally sound. The condo market offers a lower entry price, the HST rebate on new construction, and a long-horizon appreciation thesis tied to York University, IndyCar, and the supply cliff of 2028 to 2030. A portfolio holding both — a semi-detached for appreciation and rental income, a condo for entry-price investment with long-horizon upside — captures the best risk-adjusted profile available in Markham’s current market.
