Loss of use pays the rent, not the risk
Your homeowners policy funds the additional cost of living elsewhere after a covered loss. It does not become a renters policy for the house you move into. Belongings you buy or salvage, and liability at the new address, are separate questions that frequently go unasked during an exhausting year.
Salvaged contents are in an unusual position
Furniture and possessions recovered from the loss and moved into a rental are still yours to insure, and they may already be part of an open contents claim. Keeping the two straight matters, and it is the kind of detail that gets lost while a household is dealing with a rebuild.
Your homeowners policy is still running on a building site
The damaged property remains yours, is probably unoccupied, and may be under construction. That needs its own arrangement, frequently a builders risk or vacant property policy, alongside the cover at the address where you are actually living.
