How much loss of use cover do I need here?
More than a default built for an ordinary rental market. If your home becomes uninhabitable, you are competing for scarce housing in a town priced for visitors. Both the dollar limit and the number of months are worth raising deliberately, and both are inexpensive to increase.
The rental is furnished. Do I still need contents cover?
Yes, for your own belongings, and the total is usually lower than in an unfurnished place. The liability side does not change at all, and that is the half that matters most regardless of whose furniture it is.
My tenancy is seasonal. Does that affect the policy?
It can, particularly where the property sits empty for part of the year or your belongings move between addresses. It is straightforward to write correctly once we know the pattern, and awkward to claim on if nobody mentioned it.
