I don't think it's unreasonable for a condo complex to have an HOA. There's too many shared expenses and there has to be some organization to deal with it.
When I move into a house there is no way in hell I'll suffer an HOA.

I understand that a condo complex has shared expenses and an HOA solves that problem.
Personality thing. At this stage in my life I think I'd rather live in a van down by the river than a condo. At least I wouldn't have shared walls.
