How Much Is My Condo Worth in Whitby or Oshawa? August 2026 Prices and How to Price in a Small Market

By Jatin Dua · Broker of Record, RE/MAX Quantum Realty · Updated 29 September 2026 · 10 min read — Whitby’s, Oshawa’s and Clarington’s August 2026 condo apartment numbers against Durham Region and the TRREB average, what we know and do not know from such small samples, what moves a unit above or below the median in Port Whitby, downtown Oshawa or near the university campus, and how to price yours from building-level sales.

Whitby, Oshawa and Clarington condo prices, August 2026

Source: TRREB Market Watch, August 2026, condominium apartment tables. The last two rows are my own arithmetic: active listings divided by sales, and sales divided by new listings. For Whitby, only the number of sales and the average price were reliably captured from the published table; I have left the other cells blank rather than estimate them. This is one month of data, and every one of these samples is small.

Why small samples need a different approach

Whitby, Oshawa and Clarington together accounted for 28 of Durham Region’s 46 condo apartment sales in August. Split across three municipalities and many buildings, that is only a few sales per building type in a month. A single high or low sale can move a city’s average by tens of thousands of dollars.

You can see it in the numbers. Oshawa’s average was $78,245 above its median, which on 8 sales means one or two higher-priced units lifted the average well above what a typical unit fetched. Clarington’s average was $42,357 above its median on 14 sales. Neither gap says much about the market in general; it says a lot about which units happened to sell that month.

So in these markets I price differently than I would in downtown Toronto or Mississauga, where there are dozens of comparable sales every month. The order of evidence is:

1. Recent sales of your layout in your own building.
2. Recent sales of similar layouts in the most comparable nearby buildings, similar in age, fees and location.
3. If those are thin, sales from further back, adjusted for how the market has moved since.
4. Only then, the municipal and Durham Region figures as context.

Durham Region’s 46 sales, at a $457,500 median, 97 percent of list and 38 days on market, are the steadiest read on the area. The municipal figures are useful for direction, not for pricing a specific unit.

What Oshawa’s 90 percent, 60 days and 8 months mean

Oshawa’s August figures were the softest of the Durham municipalities with captured figures: units sold at 90 percent of their final list price on average, after 60 days, with 64 active listings against 8 sales, about 8 months of supply, and about 28 percent of new listings selling. As an illustration only, 10 percent off a $327,500 list price is $32,750.

On 8 sales, I would not read that as a verdict on the whole city. A couple of units that were listed too high and sold after long negotiation can drag an average sale-to-list ratio down on their own. But the direction is consistent across all the pace measures, and it matches what sellers tell me: in Oshawa, buyers have choice and take their time.

What that means for an Oshawa seller:

• Price from sold evidence. The active listings you see are asking prices, and in a market with 8 months of supply many of them will not sell at those prices.
• Budget for time. Sixty days is two months of mortgage payments, fees and property tax. Build that into your plans and into your net proceeds.
• Make the first weeks count. New listings get the most attention early. A realistic price at launch usually beats a series of reductions later.

Whitby: what we know and what we do not

Whitby had 6 condo apartment sales in August at an average of $511,321, which was $32,010 above Durham Region’s average. That is everything the published table reliably gives us. There is no captured median, no sale-to-list ratio and no days-on-market figure for Whitby that month, and with only 6 sales even a full set of figures would say more about those six units than about the city.

What I can tell you is where Whitby’s condo buyers come from and what they value. Whitby GO station on the Lakeshore East line draws commuters into Toronto; Port Whitby, around the harbour and marina, draws buyers who want the lake; and downtown Whitby, around Brock Street, draws buyers who want a walkable older-town setting. Whitby’s condo stock is small and varied, from low-rise buildings to newer mid-rise projects, which is another reason a city-wide average is a poor guide. Your price comes from your building and the buildings most like it.

Oshawa and Clarington: who is buying

• Downtown Oshawa. A mix of older towers and newer buildings around the historic core, with some of the most affordable condo apartments in the GTA. Many buyers are first-time owners and investors.
• North Oshawa near the university campus. The shared Ontario Tech University and Durham College campus in north Oshawa creates rental demand from students and staff, and investors watch units within reach of it.
• Near Oshawa GO. Oshawa GO station is on the Lakeshore East line, and walking or short-drive access matters to commuters working in Toronto or along the 401.
• The lakeshore. Buyers who want quiet and lake access look south, towards Lakeview Park.
• Clarington. Bowmanville, Courtice and Newcastle have small condo markets of their own. Clarington’s 14 August sales moved at 97 percent of list in 40 days, with about 2.6 months of supply and about 70 percent of new listings selling, a tighter market than Oshawa’s that month, but again on a small base.

Because older Oshawa towers often have larger units and higher fees than newer buildings, two units at the same size can sit a long way apart in price. That is exactly the kind of difference a city-wide median hides.

What moves your unit above or below the median

• Building age, size and fees. Older towers tend to have bigger units and higher fees; newer buildings have smaller units and lower fees. CMHC’s guidelines count 50 percent of the condo fee in a buyer’s debt ratios, against limits of 39 percent and 44 percent, so a high fee lowers what a buyer can borrow. See do high maintenance fees lower my condo value.
• Size and layout. Two-bedroom, two-bathroom units trade above one-bedrooms; a usable den adds appeal.
• Location. Port Whitby and the lakeshore, downtown Whitby, downtown Oshawa, the university area and the GO stations each draw a different buyer at a different price.
• Floor, view and exposure. Higher floors with lake or open views sell for more; units facing the 401, the rail corridor or a parking lot sell for less.
• Parking and locker. Most Durham buyers drive; a unit without parking has a much smaller pool.
• Tenancy. Investor-heavy areas can absorb tenanted units, but owner-occupiers usually want vacant possession. Read how much less a tenanted condo is worth if yours is rented.
• The corporation. The status certificate must be provided within 10 days of a request, for up to $100, and discloses the reserve fund and any special assessment. Reserve fund studies must be updated at least every three years. In older buildings, buyers read this closely; a special assessment will come up in negotiation.
• Condition. In a market with choice, a move-in-ready unit wins against the same unit needing work.

The land transfer tax and commuter points

Whitby, Oshawa and Clarington have no municipal land transfer tax; Toronto does. A buyer of a $400,000 condo pays $4,475 in Ontario land transfer tax in Durham (my arithmetic from the provincial brackets). The same purchase in Toronto would carry the City’s tax as well, another $4,475, for $8,950 in total. For a buyer who works in Toronto and is weighing a longer GO ride against a Toronto unit, that saving, together with the lower prices in Durham, is part of the case for buying here. It is worth mentioning in your listing.

Across the GTHA, Urbanation counted 4,295 completed, unsold new condos in the first quarter of 2026. Some of that supply is in Durham, and new units with builder incentives compete for the same buyers as resales. Know what nearby new projects are offering before you set your price.

How to get an accurate number for your unit

In small markets, a good valuation is a building-level exercise:

1. Run the estimator below. It gives you a range for your specific unit in about a minute.
2. Get a broker price opinion. I pull the most recent sales of your layout in your building, then the most comparable nearby buildings, going back further in time where sales are thin, and adjust for floor, view, parking, condition and fees. Then I compare with what is actively for sale. If your building has had no recent sales, how to price a condo when nothing in your building has sold explains how.
3. Check your net. In a slower market, what you walk away with matters more than the headline price.

Two tools help here: the AI condo value estimator below gives you a range in about a minute, and the net proceeds calculator turns any price into what actually lands in your account.
