My condo is noiseless. The codes in my country are strict on this. I got families with children all around me, only hear them when sitting on my balcony during summer. And codes in general makes sure that buying a modern condo is safe. Here it's 5 years where the builder has to fix stuff that's not as it should. (Just avoid buying from small shell companies, but that goes for houses as well)
Not having to care for anything but the inside is nice. Pay a small amount each month that takes care of everything. No crazy HOA stories, actually never heard of things like that here. Being 100 families in this block, actually gives us lots of power when it comes to negotiation, the fixed start-up costs for repairs etc are split over so many. My parents spend at least 10x the amount of money I do caring for their house, while I don't even have to think about it.
Price of condos here has increased much more than houses, as it's central and not possible to build that many more. Can't see why a condo inherently should appreciate less than a house? If there is demand there is demand.
