Unionville, Markham: Your Homes Are Worth More Than the City Thinks

The Vibe Right Now

If you live on one of Unionville's tree-lined streets, here is the honest truth: this neighbourhood is holding its value better than almost anywhere else in Markham. Houses are sitting at an average HonestDoor Price of $2,040,548, up 0.22% from last period, and the 3-month trend is pointing in the right direction - the predicted value of $2,036,035 is climbing past the 3-month moving average of $2,020,422. That is not a dramatic spike, but steady upward movement in this market is exactly what you want to see.

Condos tell a slightly different story. The average HonestDoor Price for a condo here is $697,201, up 2.20% from the previous period. The short-term predicted value of $682,169 is sitting just below the 3-month moving average of $688,313, so condos are taking a small breather right now. Nothing alarming - just a pause after a solid run.

The Secret Sauce - Why Your HonestDoor Price Matters More Than Your Tax Assessment

Here is the thing about your city assessment: it is a snapshot from the past. The Municipal Property Assessment Corporation updates values on a cycle that can lag real market conditions by years. A lot has happened to Unionville prices in that time.

The HonestDoor Price is a real-world check - updated continuously using actual sales data, market trends, and neighbourhood comparables. When a house here is predicted at $2,036,035 and climbing past its own 3-month average, that is live information. Your MPAC assessment almost certainly does not reflect that. If you are making any financial decision - refinancing, selling, even just understanding your net worth - the HonestDoor Price is the number you should be looking at first.

The "So What?" - Thinking About Selling This Summer?

If you have been sitting on the fence about listing this summer, the data gives you a reasonable case to move. Houses in Unionville are showing a 3.39% value change recently, and we rank 2nd in Markham for growth. Buyers looking in this price range know what Unionville represents - the historic main street, the school catchments, the overall feel of the neighbourhood. That does not go on sale.

For condo owners, the picture is still solid but worth watching. A -0.70% short-term dip is not a reason to panic, but it does suggest that if you are planning to sell, sooner is probably better than waiting to see if that trend extends. A 6th-place growth ranking out of 14 is above average - just not the front of the pack right now.

Bottom line: Unionville is one of the stronger places to own property in Markham right now. Check your HonestDoor Price today - there is a good chance the number surprises you, and in a good way.
