Genuinely feel bad for whoever ended up buying this in London, Ontario
Looking back now, it’s honestly hard to believe houses like this were selling for these prices in London during the 2021–2022 market frenzy. A pretty basic looking house sitting on a 29 x 114 ft lot, with an unfinished basement and barely any upgrades or add-ons, sold for $945K at the peak of the madness.
What makes it even crazier is that London’s market did cool down later on, but nowhere near as brutally as places around the GTA or the Cambridge–Kitchener–Waterloo region. Still, imagining how the buyer must feel today is rough, especially when a bigger and better house on a corner lot directly across the street (1691 O'HANLAN Lane) sold for only $665K in January 2026.
That whole period in the housing market felt disconnected from reality. People were pressured into overpaying out of fear of being priced out forever, and many buyers ended up making life changing decisions in what now feels like one of the most irrational housing bubbles we’ve seen.

$1.5M then your neighbour buys for $1.15 ... 2 weeks later
$1.5M then your neighbour buys for $1.15 .. 2 weeks later ..
The houses are similar, both need work the land sizes are exactly the same.. I'm not sure what I'd think after buying at $1.5M
Cooking… $815k 558 sqft 1 bed purchased Aug 2025, listed 9 months later at $779k ($1398 psf, good luck!!) It has a combined laundry room and den!
There’s no way they’re getting off with only a $35k loss
What shadiness is happening here…?!?
Look at the sales history on this one…just sold, relisted and apparently sold back to the same buyer at a higher price.

250K+ loss in Toronto
233 Atlas Avenue, 265K loss in 5 years. I know 2021 was peak mania but not sure why you would pay 1.8mm + in that neighbourhood for a semi with no parking. High end finishes but still pretty wild.
