Oshawa Housing Market: Home Prices and Sales | September 2026

Oshawa is the largest city in Durham Region, at the eastern end of the Toronto Regional Real Estate Board’s (TRREB) territory, and has its own census metropolitan area separate from Toronto’s. TRREB’s Market Watch reports Oshawa’s sales, prices and MLS® HPI benchmarks each month; this page uses September 2026 (released in October 2026) and the year-earlier September 2025 edition. The housing market overview explains the measures.

Oshawa home prices, September 2026

TRREB Market Watch, September 2026: Oshawa and Durham Region rows of the municipal tables; GTA totals from the Toronto housing market report.

Oshawa’s average sale was 32% below the GTA-wide average and 18% below Durham Region’s. Over the year it went from $740,862 to $679,861, a change of −8.2%, a bigger move than the -6.11% on the benchmark. In September 2026 the average was 3% below the benchmark itself, so the homes that sold that month were on the whole less expensive than Oshawa’s typical home.

Detached, attached, townhouse and apartment benchmarks are TRREB’s single-family detached, single-family attached, townhouse and apartment HPI types. Outside detached houses, Oshawa’s monthly counts are small, so a few sales can move a type’s average.

Detached houses made up 71% of Oshawa’s sales. The average detached sale of $748,346 compares with $1,292,016 for a detached house across the GTA.

Sales, listings and inventory

Oshawa recorded 125 sales in September 2026, against 173 a year earlier, from 448 new listings (522 the year before). That month’s sales-to-new-listings ratio was 27.9% and the 660 homes for sale amounted to 5.3 months of sales. TRREB’s 12-month averages tell a tighter story: a ratio of 39.2% and 3.6 months of inventory, right at the 3.6-month line below which CREA calls a market a seller’s market. Durham Region as a whole had 3.5 months. Homes sold for 98% of their final list price on average, after 34 days on the market. For the year to date, 1,377 homes sold at an average of $703,003 (−8.1%).

Buying costs in Oshawa

At Oshawa’s average price, Ontario’s land transfer tax (all provinces) is $10,072, the only transfer tax due in Durham Region; a first-time buyer refund of up to $4,000 lowers it to $6,072. The smallest down payment allowed on that price is $42,986, 6.3% of it, and the mortgage insurance premium that comes with it is $25,475.

Property tax weighs more here than in the York and Peel suburbs. Oshawa’s 2026 residential rate is 1.5753% of assessed value (0.6592% city, 0.7631% Durham Region, 0.153% education), or $1,575 a year per $100,000 of assessment, against 0.7229% in Markham and 1.2534% in Brampton. Bills are figured on MPAC assessments, which in Ontario are still based on January 1, 2016 values.

Income needed against Oshawa incomes

At the average price with the minimum down payment, qualifying takes about $153,000 of household income; with 20% down, about $134,000 (how it is calculated). The Oshawa census metropolitan area’s median household income was $102,000 in 2020 according to the 2021 Census, 5% above the Toronto area’s $97,000. The income needed at Oshawa’s average is 1.5 times the local median.
