Why are fees so high on reverse mortgage?

Reverse mortgages are usually more expensive than traditional mortgages mainly because the FHA Mortgage Insurance Premium is calculated off of the entire value of the home rather than the amount borrowed. Reverse mortgages require more paperwork and documentation than other types of loans. The fees associated with a reverse mortgage are also typically higher due to the additional costs of originating, processing, servicing, and managing the loan.
