Under a Land Contract, the responsibility for the property insurance payment and the securing of a policy is a negotiated item.
If the contract is already in place, read the Land Contract document itself; insurance responsibility is typically an item covered within the contract.
If the contract is in discussion, such a topic should be decided upon during negotiations.
