Thought I'd post an update.
Of all the proposed solutions, I chose to rent a detached house and will move out soon. It will be a PITA, but hopefully worth it.
What comes next is mostly me complaining about construction ????.
The situation has become unacceptable. I've received a lot of recommendations regarding how to deal with neighbor noise, but again, just in case it wasn't clear, this is not about noisy neighbors, but very normal daily routine sounds.
To give you an example, typing at the computer or even the click of a mouse is something that can be heard between the units. I rely a lot on the computer, and lately I can't even do that past 19PM. In my book, that's not my fault or the neighbors, but of whoever built the condo like this to turn a cheap profit.
It's sad, because a very good condo, with well-maintained facilities, perfect location, reasonably priced, it's completely ruined by this huge problem. At least in my case, knowing this, I would never invest in a condo in the future and certainly stick to a house.
Thanks for all the recommendations!
