I have a family member with small kids that bought a condo flat in Montreal in one of those ubiquitous stick-framed midcentury quadplexes. The downstairs neighbor complained aggressively about "kids too noisy" and sued my family member. The family member was unable to work it out with the neighbor, and faced with the prospect of the suit actually going to trial, their lawyer recommended settling by selling the unit to the downstairs neighbor for a $100K CAD haircut. Closing that sale was a huge relief to them after having endured almost two years of constant harassment by the downstairs neighbor. Sharing to warn others.
