Will it affect my policy if I rent my house?

Yes, definitely. As the homeowner renting, your rental would need to have an endorsement added to your current property policy. As the landlord, your coverage is only on the structure itself and your financial interest in it. Your tenant’s personal possessions are not covered under your policy. Your renters would need to be covered under their own tenant’s policy. This will protect their own personal liability, contents and additional living expenses in case of a claim.
