The Short Answer

What affects home value in Markham? Some factors you cannot change — location, school catchment, community, lot, home type, and market conditions. Others you can influence — condition, updates, presentation, staging, and pricing strategy. Knowing the difference is how you maximize your home's value.

Every Markham homeowner wants to know what their home is worth — but understanding the factors that determine value is what allows you to maximize it. Some of these factors you cannot change; others you can influence. Knowing the difference is the key to getting the most for your home. Michael John Lau, a leading Markham REALTOR® and CPA/CMA, breaks down the factors that affect home value in Markham.

Location Factors — The Foundation of Value

Location is the most powerful determinant of home value, and in Markham, several location factors are particularly significant.

School catchment

In Markham, school catchment is one of the most powerful value drivers. Homes in top-ranked catchments — Bur Oak, Pierre Elliott Trudeau, Unionville High School — command significant premiums. The Bur Oak catchment in Wismer Commons consistently produces some of the strongest sale prices in the city. School catchment can add tens of thousands of dollars to a home's value.

Community and neighbourhood

The specific community matters enormously. Markham's most prestigious communities — Unionville, Angus Glen, Cachet, Bayview Glen — command premiums reflecting their desirability, character, and the buyer interest they generate. Quality photography and professional marketing are essential to achieving full value.

Lot and position

Lot size, frontage, orientation, and position on the street all shape value. A premium pie-shaped lot, a ravine backing, or a quiet interior street position each adds value over an otherwise identical home.

Home Factors — Size, Type, and Condition

Size and home type

Square footage, bedroom and bathroom count, and property type — detached, semi, townhouse, condo — establish the baseline. In Zolo, August 2026: Markham average home ~$1.1M · average detached listing ~$2,136,000 · average condo ~$738,000 · ~32 days on market · 98.9% sale-to-list ratio.

Condition and updates

A well-maintained, updated home commands more than a comparable home in dated or poor condition. Kitchens, bathrooms, flooring, and mechanical systems all influence what buyers will pay.

Market Factors — Conditions and Timing

Economic conditions

Broader economic conditions — employment, consumer confidence, the economic outlook — affect buyer demand and home values.

Seasonality

The time of year affects the market, with spring and fall typically the strongest selling seasons.

What You Can and Cannot Influence

Understanding which factors you can influence is the key to maximizing your home's value.

You cannot change: location, school catchment, community, lot, home type, and market conditions. These are fixed factors that establish your home's value baseline.

You can influence: condition, updates, presentation, staging, and pricing strategy. By improving your home's condition, making strategic updates, presenting and staging it well, and pricing it correctly, you can maximize the value your home achieves within its baseline.
