The present disclosure describes various computer systems and computer-implemented methods that assist in planning for this type of mortgage. Various factors may be considered, such as, the initial loan principal, ages of one or more borrowers, and a desired mortgage interest rate, and calculates. Different scenarios for conversion from the forward portion to the reverse portion of the mortgage may then be calculated and presented. For example, one or more forward mortgage payment schedules may be calculated and future reverse mortgage capacity may be presented. In some embodiments, the reverse mortgage capacity is used to pay some or all of the forward mortgage portion.
