How the numbers connect

The median sale price decreased by $118,150 between the September 20, 2026 and October 10, 2026 reports.

Inventory Growth Outpaces Sales Volume in Newmarket

Active listings in Newmarket reached 407 units as of October 10, 2026, up from 316 units reported on September 20, 2026. This increase of 91 active listings occurred while sales volume dropped to 37 sold listings from 72 in the prior report period. The divergence between rising inventory and falling sales indicates that properties are remaining on the market longer rather than clearing quickly.

Days on market averaged 33 days in the October 10, 2026 report, compared with 30 days in the September 20, 2026 report. New listings totaled 220 units in October, representing a 3.51% year-over-year decline. These figures suggest that while new supply is entering the market at a slower pace than the previous year, existing unsold inventory is accumulating faster than it is being absorbed by buyers.

The strongest counter-case

New listings in Newmarket were down 3.51% year-over-year as of October 10, 2026, suggesting that new supply growth remains constrained despite rising active inventory. Sources: [Newmarket Housing Market Report: 10th Oct, 2026 | Wahi]

Next 3 months, January 2027

Prices: falling. Continued pressure on median sale prices due to elevated active inventory relative to sales volume. Why: Active listings increased by 29% while sales volume decreased by 49% between September and October 2026 reports. Buyers: wait. Higher inventory and longer days on market provide more negotiating leverage for buyers. Sellers: wait. Elevated competition from other active listings may require price reductions to achieve sales. Watch: A sustained drop in active listings below 350 units would indicate inventory absorption is accelerating. Confidence: moderate.

Next 6 months, April 2027

Prices: flat. Median sale prices may stabilize if new listing volumes remain consistent with seasonal patterns. Why: Only two data points are available, and the observation periods for these reports are not explicitly defined. Buyers: either way. Price direction is uncertain beyond the immediate term due to limited historical data. Sellers: either way. Market conditions may normalize as seasonal demand shifts occur in spring. Watch: Year-over-year new listing trends reversing to positive growth would signal stronger seller confidence. Confidence: low. Sources: [Newmarket Housing Market Report: 10th Oct, 2026 | Wahi]

Next 12 months, October 2027

Prices: flat. Prices likely to remain within the current range absent significant macroeconomic changes. Why: Insufficient local evidence exists to project specific price movements over a full year. Buyers: either way. Long-term price direction depends on factors not captured in the current two-month dataset. Sellers: either way. Sellers should monitor broader economic indicators alongside local inventory levels. Watch: A change in provincial housing policy affecting four-unit zoning could alter long-term supply dynamics. Confidence: low. Sources: [Newmarket Housing Market Report: 10th Oct, 2026 | Wahi]

Assumptions: The September 20, 2026 and October 10, 2026 reports represent comparable market snapshots for Newmarket; No major external shocks to housing demand or supply will occur during the forecast period. What would reverse this: If new listings surge significantly above the 220-unit level observed in October 2026, the inventory buildup could accelerate further, deepening price declines.
