Unionville Home Values: What Sellers Need to Know
Quick answer: Unionville is Markham's best-known and busiest neighbourhood, with the city's widest price range. In the second quarter of 2026, TRREB recorded 45 detached sales at a median of $1,625,000, while Downtown Markham condos, which TRREB counts inside Unionville, typically trade around $650,000. Because one postal area holds three very different markets, averages mislead here. Unionville sellers need a street-level evaluation, and Michael John Lau provides one free.

The Neighbourhood
Why Unionville Commands a Premium
Every Markham neighbourhood has buyers. Unionville has believers. Historic Main Street Unionville, with its restaurants, the Varley Art Gallery and Toogood Pond, anchors a community that blends century homes, established executive streets and the modern towers of Downtown Markham.
That demand shows up in the numbers. Unionville recorded 159 sales across all home types in Q2 2026, by far the most of any Markham community. Buyers pay a premium for specific things here, and the listings that prove those premiums, rather than just mention them, are the ones that sell for the most.
- A walk to Main Street Unionville and Toogood Pond
- Mature, larger lots on established streets
- Heritage character, inside and near the Heritage Conservation District
- Unionville GO and Viva Purple on Highway 7
- Nearby schools such as Unionville High School and its Arts Unionville program
TRREB's Unionville community includes the Downtown Markham condo towers south of Highway 7. That is why its all-types median was only $735,000 in Q2 2026 while detached homes sold for a median of $1,625,000. Any valuation built on the community average will be wrong for almost every home in it.
Current Values
What Unionville Homes Are Selling For
TRREB's Q2 2026 community report is the most recent official neighbourhood-level data. Condo and townhome figures are September 2026 medians.
| Segment | Recent reading | Seller note |
|---|---|---|
| Detached | Median $1,625,000, average $1,713,000 (45 sales, Q2); September median $1,600,800 | Thin comparables on premium streets; precision pricing is everything |
| Townhomes and semis | About $1,000,000 to $1,180,000 (September) | Few sales each month; school-area demand drives competition |
| Condos (Downtown Markham) | About $650,000 median (September, 16 sales) | Highest-supply segment; presentation separates listings |
| All home types | Median $735,000, 159 sales, 99% of list, 30 days (Q2) | Pulled down by condos; do not price a house from this number |

A Main Street-adjacent heritage home, a Downtown Markham condo and a 1980s executive home on a quiet crescent share a community name, not a comparable set. Unionville's September 2026 detached median, $1,600,800, matched the price Michael's sellers achieved at 56 Ingleborough Court, where a targeted renovation plan drew six offers and $200,801 over asking.

Selling Strategy
How Unionville Homes Sell for Top Dollar
Unionville rewards preparation and precision more than any other Markham address.
- 01
Price to the micro-market, not the postal code
Unionville's range is Markham's widest. The evaluation that matters compares your home against your street's sales. Heritage, executive and condo homes are different games.
- 02
Meet the highest presentation bar in Markham
Unionville buyers arrive with expectations set by the neighbourhood itself. Staging, photography and video are not upgrades here; they are the entry fee. See the standard in the seller services plan.
- 03
Market the location premiums explicitly
Walk time to Main Street. Nearby schools, named. GO access, timed. Listings that document Unionville's premiums capture them in the price.
- 04
Use competition deliberately
Correctly positioned Unionville listings can draw competing offers, which takes accurate data and steady nerves. See it at 24 Juniper Crescent, four offers and $93,000 over asking in 7 days.
What lifts values
Worth highlighting
- Main Street proximity and walkability
- Lot size and mature trees
- Heritage character, presented well
- Renovations that match what buyers on your street expect
What softens values
Worth fixing before you list
- Deferred maintenance on older and heritage homes
- Condo supply in a given quarter
- Overpricing into a well-informed buyer pool
- Heritage rules buyers do not understand, left unexplained

Unionville Seller Questions
It depends on the home type. In Q2 2026, TRREB recorded 45 detached sales in Unionville at a median of $1,625,000 and an average of $1,713,000. Across all home types the median was $735,000, because TRREB's Unionville area includes the Downtown Markham condo towers. Condos typically sold around $650,000 in September 2026.
Detached homes in Unionville sold in 25 days on average in Q2 2026, at 98% of list price. Well-prepared, accurately priced homes often sell faster, and some draw multiple offers. Overpriced homes sit longer and usually sell for less in the end.
Walkability to Main Street Unionville and Toogood Pond, larger mature lots, heritage character, Unionville GO and Viva access, and nearby schools such as Unionville High School. Each one should be shown and measured in your marketing, not just mentioned.
Markham's market had about 4.1 months of inventory in August 2026, which is balanced territory. Well-presented, accurately priced Unionville homes are still selling close to list and sometimes above it. The right timing depends on your home and your next move; see is now a good time to sell?
Unionville is the established, higher-priced choice, with a Q2 2026 detached median of $1,625,000. Cornell is the newer planned community to the east, with a detached median of $1,278,000. See the full Unionville vs Cornell comparison.
