DC is buying a share-of-freehold flat. There are 8 flats in the building. Six are let out, but his and one other are owner-occupied. The building insurance is shared evenly by all of the flat owners. It includes cover for loss of rental income, which presumably pushes up the cost. I'm curious - is it usual for rental-income cover to be shared equally by all freeholders?
For further context, the property has had s couple of past claims on its insurance, and the insurance cost seems relatively high.
