The municipal tax assessment divisions, residential construction grids, and consumer banking desks within the Durham Region are updating local valuation indices. Tracked under provincial macroeconomic and local asset development portfolios on Monday, July 13, 2026, real estate ledger teams finalized the monthly baseline report Oshawa home prices jump 2.5 per cent to $726,544 in June 2026. Data authenticated by the Toronto Regional Real Estate Board (TRREB) reveals a distinct month-over-month price consolidation, driven primarily by a tightening supply loop that has systematically reduced local inventory layers across the municipality.
Market analysts note that while short-term pressure squeezed prices upward by $17,821 from May, the macroscopic annualized curve reflects a broader cyclical correction, leaving average values five percent below historical mid-summer peaks recorded in 2025.

-
The Inventory Deficit: Total active inventory contracted sharply to 686 open listings by the end of the month, representing a steep 11.8 percent plunge compared to the supply pools available during the same interval last year.
-
The Semi-Detached Anomaly: Bucking the broader downward trend seen in detached and condo classes, semi-detached formats saw a strong 5.1 percent month-over-month surge, closing at an average of $630,933 as buyers seek out entry-level freehold options.
-
The High-Density Condo Drop: High-density apartment-style condos experienced severe downward adjustments, dropping 13.9 percent in a single month to rest at an average of $316,000—representing a massive 27.3 percent year-over-year deflation from 2025 values.
