Tenant guarantors are or at least they should a landlords insurance of sorts. Should a tenant fail to fulfill their lease agreement there always will be someone whom the landlord will expect to pay whatever is owed. Many landlords however never ever mention that a guarantor would be great for both parties. Having a guarantor lessens the risk of tenants failing to pay their rent or damaging property. Why do you think most landlords never make it a condition that the tenants should have a guarantor? Are they afraid tenants wouldn't like this?
