if you buy into a condo HOA, your unit is part of a connected structure. So the HOA is underinsured for the building/structure/roofs, etc. What if there were a disaster. And say you did have an HO-6 policy with a bridge policy to cover the HOA shortfall on your unit. There won't be enough HOA insurance to rebuild the condo building - you aren't going to just rebuild your individual condo unit. I don't understand. I would avoid such an HOA, but that's just me.
