Inventory Surge Defines Balanced Market Conditions

Active listings in Cornwall reached 1,286 units at the end of August 2026, representing a 21.9% increase from the previous year. This substantial rise in supply pushed months of inventory to 5.3, up from 3.7 months in August 2025 and above the long-run average of 3.6 months for this time of year. The accumulation of unsold homes indicates that seller activity has outpaced buyer absorption over the past twelve months.

The market characterization shifted from tight to balanced as inventory levels climbed steadily through the summer. July 2026 saw an all-time record of 568 new listings, contributing to 4.3 months of inventory before August added another 463 new residential listings. With supply now well-matched to demand, the Cornwall and District Real Estate Board describes the environment as offering opportunities for both buyers and sellers rather than favoring one side exclusively.

Price Moderation Accompanies Rising Supply

The year-to-date average sale price stood at $512,238 as of August 2026, reflecting a 3.5% decrease from the first eight months of 2025. Monthly average prices showed volatility, with June 2026 averaging $507,491 and July 2026 reaching $506,780, both down significantly from their respective 2025 counterparts. This downward pressure on average prices aligns with the increased availability of homes, suggesting that sellers are adjusting expectations to match the expanded inventory pool.

Sales volume demonstrated mixed momentum during the same period, with 242 homes sold in August 2026 following 308 sales in July. While July marked the fourth-best performance on record for that month, August sales represented a 16% year-over-year decline. The divergence between strong monthly peaks and softer subsequent months highlights a market in transition, where heightened competition among listings is moderating transaction volumes and influencing final sale prices across the Cornwall region.
