Which of the following can be collected from tenants at the beginning of the lease by the property manager

Renter's insurance is a policy that protects tenants' personal property and liability within the rented unit. However, the premium for renter's insurance is typically paid directly by the tenant to the insurance provider, rather than collected by the property manager at the lease's commencement. Therefore, it does not qualify as a fee collected by the property manager.

An accident rider guarantee is an additional clause or endorsement in an insurance policy that provides extra coverage for specific accidents. This is not a fee or deposit that property managers collect from tenants; rather, it is a part of an insurance contract, which tenants may choose to purchase separately.

A detainer fee is associated with legal proceedings to regain possession of a property from a tenant, typically after eviction proceedings have started. This fee is not collected at the beginning of a lease; instead, it comes into play only when a tenant is in breach of lease terms or facing eviction.
