If you've been watching the "For Sale" signs on your street, here's what's actually happening in O'Neill. The story is different depending on whether you own a house or a condo - and the gap matters.
The one house that sold in O'Neill this past period went for $707,500 - and the buyer paid 101.07% of the asking price. That means they paid above list. In plain terms, demand is still outpacing supply on the house side. Properties are moving in an average of 13 days, which is quick. If your house is priced right, it's not sitting.
One thing worth watching: the predicted market value for houses sits at $675,746, which is running a bit below the 3-month moving average of $687,516. Values have dipped 2.17% recently. The house market here is holding up, but it's not accelerating. On the Oshawa neighbourhood leaderboard, O'Neill houses rank 16 out of 20 for growth - that puts us in the lower half. Days-on-market rank is 3 out of 8, meaning we sell faster than most. Price rank is 4 out of 8, so we're above average in value compared to other Oshawa neighbourhoods.
The condo side is a different picture. The average HonestDoor Price for condos in O'Neill has dropped 5.60% to $425,339. That's a real move, and condo owners should pay attention. The good news is that the predicted market value of $450,548 is actually trending up against the 3-month moving average of $447,546 - so there's a floor forming.
On the Oshawa condo leaderboard, O'Neill ranks 5 out of 19 for growth. That puts us solidly above average. Compare that to nearby Central at a predicted $506,261 and Centennial at $512,159 - we're priced lower, but our growth momentum is real. For condo investors, that gap could be an opportunity.
Here's the thing about your city assessment - it's a snapshot from the past. It doesn't know what sold on your street last month. It doesn't adjust when the market shifts. The HonestDoor Price is updated in real time using actual sales data, so it reflects what a buyer would likely pay today - not what a government office calculated a year or two ago.
Right now, the average HonestDoor Price for houses in O'Neill is $686,800. If you're only looking at your tax assessment, you could be leaving money on the table when you price your home - or worse, you could be overpaying on a purchase because you didn't check the real-world number first. Think of the HonestDoor Price as the honest gut-check your assessment was never designed to be.
If you own a house in O'Neill and you're thinking about listing this summer, the conditions are still in your favour. Buyers are paying over asking, homes are moving in under two weeks, and the average sale price is sitting above $700,000. That's not a bad place to be.
That said, the growth rank of 16 out of 20 tells us O'Neill isn't the hottest-appreciating pocket in Oshawa right now. If you're waiting for values to climb significantly before selling, the data isn't giving us a strong reason to hold out. Selling into current demand - while buyers are still active and motivated - is likely smarter than waiting for a growth surge that isn't clearly coming.
If you own a condo, the 5.60% drop in HonestDoor Price is worth a serious look before you make any moves. The upward trend in predicted value is encouraging, but you want to know exactly where you stand today - not six months ago. Pull your HonestDoor Price, compare it to what Central and Centennial condos are doing, and make a decision based on current numbers.
Bottom line: O'Neill is a solid, above-average-priced neighbourhood in Oshawa. Houses are moving fast and selling strong. Condos are stabilizing. If you're selling this summer, price it right and move with confidence. If you're buying, know that competition is real - especially on the house side.
