What This Means
The size of the difference depends on the measure. Average prices put East Gwillimbury $127,143 higher and median prices put it $103,500 higher. TRREB’s MLS® HPI benchmark, which describes a typical detached home with defined characteristics and is less affected by which homes happened to sell that month, puts it $52,100 higher, less than half the average difference. With only 25 detached sales in East Gwillimbury, the average should be read alongside the median and benchmark. The benchmark provides another perspective alongside average and median prices. None of these figures replaces comparable sales for the specific homes involved.
On sale to list price and days on market, the two communities look alike: both averaged 96% of list price, with 35 days on market in East Gwillimbury and 31 in Newmarket. Supply looks different. TRREB reported 196 active detached listings in East Gwillimbury and 213 in Newmarket at the end of September, but East Gwillimbury recorded 25 sales against 36.
Detached benchmark prices were lower than a year earlier in both communities, by 9.81% in East Gwillimbury and 8.45% in Newmarket. A year over year change does not predict the next month.
An earlier comparison on this site used April and May 2026 averages. That comparison mixed two reporting months and cannot be set directly against September. What September shows is that the size of the difference depends on the measure, from $52,100 to $127,143.
Each figure is a difference between reported numbers, not the amount you would have available after the move. See the net sheet framework to estimate proceeds from your sale, and How Much Does It Cost to Move Up in York Region? for the costs layered on top of the purchase price. Differences in lot size, home age and finish level between specific properties also matter, and a community figure cannot show them.
This comparison uses detached homes only, so it fits a move from one detached home to another. If you own a townhouse or a semi detached home, your starting point is different. TRREB reported 9 attached, row and townhouse sales in Newmarket and 6 in East Gwillimbury in September, too few for a reliable monthly comparison.

Why is the benchmark difference smaller than the average difference?
The average reflects whichever homes sold in the month, and East Gwillimbury had only 25 detached sales. TRREB’s MLS® HPI benchmark describes a typical detached home with defined characteristics, so it is less affected by which homes sold. The benchmark provides another perspective alongside average and median prices. None of these figures replaces comparable sales for the specific homes involved.

At the end of September 2026, TRREB reported 196 active detached listings in East Gwillimbury and 213 in Newmarket, with 113 and 154 new detached listings during the month. East Gwillimbury had 25 sales and Newmarket had 36, so East Gwillimbury had more listings relative to sales.
Is a move from Newmarket to East Gwillimbury mainly about space or price?
That depends on the homes. The three measures produce different community level comparisons. They are not a budget range for your move. The lot size, layout and location of the specific properties usually decide whether the move adds space. A community figure cannot show that.
