Buying a condo – best ways to find out about outstanding/past maintenance/updates and assessments

I'm buying a condo for retirement in another city and am working with a buyer's realtor there. As the title indicates, I know about a number of the possible pitfalls: roofs that are 10+ years old, other mechanicals needing work, current assessments for maintenance and repair. (I'm also not interested in renting or buying anything other than a condo apartment for lots of carefully thought-out reasons that aren't part of this post.)

What I'm not sure of is the best way to find out about such things and what sorts of things generally are possible to discover without walking around the building or the neighborhood and talking to people. I'm also not sure that I can rely on my realtor to find these things out because 1) I'm eight hours away, and 2) I'm not spending a ton of money. I figure there's likely more incentive to find things out if I'm buying a five-year-old $500k house than there is when I'm buying a $100k condo that was built in the 1920s/30s.

Are private condo HOA agreements, financials, and so on publicly accessible? Are they something I can find, or should I just politely insist on looking at them and let the realtor locate them? Maybe I'm just suspicious, but I want to look at these things before I even ask the realtor to take a video of a condo unit.
