Earlier quoted context omitted.
Some condo corporations are poorly managed and lack sufficient emergency funds, or proper maintenance, and thus resort to special assessments that are not funded in advance. The same is true of many homeowners.
As a homeowner, that is 100% in your control whereas with a condo it isn’t. I have seen so many times in the local news about condos who are underwater because the board decided to not proactively save and fix things which was a democratic decision made by the board. Honestly I have such low trust in the ability for humans to plan for the future over the now. It is like a bug in our psychology.
Most home owners don’t do this either, but it’s pretty much the same thing short of an association leaving stuff so long it ends up being more expensive overall.
Stuff like siding isn’t really all that hard to predict - it typically has a useful life and easy to calculate like a roof. Might get lucky or unlucky but it all averages out in the end over time. If you’re not saving/spending about 2% of your property value each year for maintenance you are almost always running on hopes and prayers.
Granted, the outlier cases a condo owner has far less control over the situation- including neglect to the point of building collapse.
