A landlord insurance policy will typically have additional cover that a standard house insurance policy does not include. These are often called a Landlords Extension or Landlords Protection.
This provides cover for loss of rent, accidental and intentional damage by tenants, meth contamination and landlord contents cover.
These are designed to minimise the risks of renting your property. For example if your property is smashed up by the tenants there is malicious damage cover. If your house is flood damaged and can no longer be rented there is further loss of rent cover.
The level of loss of rent, meth contamination and malicious damage cover is very important to consider when comparing landlord insurance policies.
