That's what makes title insurance different from casualty insurance.All things being equal, the risk of a missed defect in title on a $100k property is the same as the the risk on a $1 MM property and both risks should be negligible if a good search and examination of title is done and a competent closing is conducted before the policy is issued.In either case the agent keeps 70% of the premium for the agent's portion of the assumption of that risk.
