In which situation could Bill potentially claim lost rental income?

The ability for Bill to claim lost rental income hinges primarily on the specifics of his insurance policy. If the insurance policy explicitly includes coverage for lost rental income, this would provide a legitimate basis for his claim. Policies can vary significantly, and those that cover loss of rental income typically do so under certain conditions, such as damage to a property that renders it uninhabitable for tenants.

In the context of this scenario, understanding that the insurance contract outlines the coverage is essential. If Bill has a policy that includes this clause, he would be able to demonstrate that he has lost income due to a covered event, making the claim valid.

The other scenarios do not directly imply that he would have a right to claim lost rental income. Moving to a new rental unit may not impact his current income status. Extensive damage might be relevant, but without the insurance coverage aspect being in play, it does not automatically lead to a claim. The departure of a roommate could result in a loss of income, but similarly, it doesn't relate to a claim without the context of insurance coverage for lost rental income. Hence, the crucial point is that the policy itself must recognize and allow for claims of lost rental income for Bill to pursue this financially.
