Regarding the "owning a condo not being ideal", it's actually the norm in many countries, assuming by "condo" you mean a flat in a shared building with many houses - where I'm from, condominium is the name you give the association of neighbors, not the structure. Almost 50% of the EU residents live in flats[0]and have to indeed communicate with their neighbors and solve common issues together through a management company or directly through the owners association, depending on the building. I think you're making it out to be more complex than it is.
