Occupancy changes and the policy should know
A property you occupy for part of the year and rent for the rest does not fit a standard homeowners form or a standard landlord form neatly. Some carriers write it specifically, some require a landlord policy year round, and some decline. Describing the pattern honestly is what gets it placed correctly.
Your own belongings are still in the house
Unlike an ordinary rental, a part-year arrangement usually leaves the owner’s furniture and possessions in place while tenants are there. That is a contents exposure most landlord policies are not written for, and it needs addressing explicitly.
The empty weeks between are their own risk
Between your stay and the tenancy the house may sit unoccupied, which engages the vacancy conditions. On a seasonal pattern those gaps are predictable, which means they can be planned for rather than discovered.
