My gut feeling is that repairs and maintenance cost more with condos than if you own a home and you're handy to fix minor stuff and know how to find good contractors for bigger jobs. I imagine condo jobs becomes more difficult and contractors charge more for those jobs. But I don't have data to back my hunch. Condo has extra issues in dealing with neighbor problems (issues with garbage, pets, unpaid fees, noise, etc...) and you have to maintain shared spaces (hallways, elevators, etc...) and you end up paying for that via your condo fees.
"Finding good contractors" can be pretty challenging, especially finding good contractors at a good price.
Condos can also benefit from efficiencies of scale - e.g. there are plenty of small jobs on myself that I do myself, but between the time spent on research, and expenses/trips to pick up supplies and tools, I'm spending multiple hours of my time/money on things that someone experienced/equipped could bang out in 20 minutes - but any decent handyman is going to charge their call out rate of $100 + materials for a 20 minute job. vs at appropriate scale a condo corp can effectively just have/share a full-time handyman and save a pile of overhead.
