I’m with all the others saying back away.
Your own insurance covers your property. The community insurance covers communal areas.
As far as I am aware you can’t take insurance out against problems that may occur in those communal areas. You are already paying for that insurance as part of your community fees.
If the current community claim is not resolved (or future claims) then unfortunately the community will have to pay for the damage. Depending on the scale of the damage and the number of properties in the community, that could be a hefty increase in community fees. In that scenario you would be paying for damage that happened before you bought your property. Or you could be asked for a large one off contribution to repair the damage and as it’s now your property it’s your debt.
Have you asked to see the minutes of the AGM’s since the damage occurred. Even though there will be a couple of years missing because of covid I’m sure the meetings have been full of “healthy debates”.
Even if you buy the property at a bargain rate, you will still get stung by a hefty tax bill.
Far too many negatives to even consider a purchase.
