How We Rank Markham Real Estate Agents
Our rankings are built from verified MLS transaction data, not advertising spend. For every agent we analyze more than fifteen performance signals, including sales volume in your city and zip code, recent and all-time transactions, days on market, negotiation results (how far above or below list price an agent's clients actually close), price-point fit, and verified reviews. The agents shown first are those whose verified results put them at the top of the Markham market today.
Agents cannot pay for placement in these rankings. The underlying data refreshes as new closed transactions are reported, so rankings shift with real market performance. Learn how we rank agents.

Markham Real Estate Agent FAQs
How were these Markham real estate agents ranked?
Rankings are built from verified MLS transaction data. We analyze more than fifteen performance signals for every agent, including sales volume in your city and zip code, recent and all-time transactions, days on market, negotiation results, price-point fit, and verified reviews. Agents cannot pay for placement.
How many real estate agents are in Markham?
Our data covers 750 real estate agents serving the Markham area. The count represents agents with transaction activity recorded in our Markham market data, not simply everyone holding a license.
What does the median sale price in Markham mean for sellers?
Markham's median sale price is $169,915 as of July 2026. Half of recent sales closed above that figure and half below. It is a useful baseline for understanding the market, but an experienced local agent will price your home against comparable recent sales in your neighborhood, not the citywide median.
Does it cost anything to use EffectiveAgents?
No. EffectiveAgents is free for home buyers and sellers, with no obligation to work with any agent we match you with.
Do agents pay to be ranked or featured?
No. Agents cannot pay for placement anywhere in these rankings. Positions are earned from verified transaction performance only.
What commission do Markham realtors charge?
Commissions are negotiable and vary by agent, service level, and transaction. There is no set rate, and recent industry changes have made commission structures more flexible than ever. Discuss the structure directly with your agent before signing a listing or buyer agreement.
Should I use a local Markham agent or a national brand?
The individual agent matters more than the brand on the sign. Offices within the same national franchise vary widely in performance, and the agent you hire, not the logo, prices your home, negotiates your contract, and manages your closing. A strong local agent brings firsthand knowledge of Markham neighborhoods, pricing patterns, and buyer activity. Compare agents on verified local results such as recent sales, days on market, and negotiation outcomes rather than name recognition.
What questions should I ask a Markham realtor before hiring them?
Ask how many homes they have closed in Markham in the past year, what their average sale-to-list ratio is, and how much of their business is in your neighborhood and price range. Ask how they will market your home or find you listings, and how often they will communicate. Strong agents answer with specifics. Verified transaction data is the fastest way to confirm what you hear.
