Here's how to update the case study to include a mortgage and then a reverse mortgage:
1) Launch Add-ins/Retireator/Setup...change Parameters to "Advanced" and then check the Home/Mortgage box
2) On the Main page set the State, Local, and Foreign Income Taxes to Florida
3) On the Expenses tab enter a Home Value of $120,000, a Mortgage Origination Date of 1/15/2020, an Original Balance of $96,000, and a Term of 360 months (30 years)
4) Lower the Miscellaneous 1 expense to $2100 / month.
5) Retireate! The Retirement Date is now 9/14/2046
6) Let's set the Mortgage Extra Payment to $100 / month just for fun.
7) Retireate! This pushed out 3 months and 1 days to 12/15/2046. That's interesting.
8) Let's set up a reverse mortgage starting at age 62. On the Expenses tab enter a HECM Origination Date of 1/12/2042
9) Retireate! This pulls in 1 year and 22 days to 11/23/2045.
The Retireator estimates a Principal Limit Factor with these parameters of 32%. Flip to the Annuitizer page and note a Lump Sum of $78,528 in the year 2042. This results in annuity payments of $6786 annually (not inflation-adjusted by default, configurable through the Main page).
Flip to the Annualizer page which is a cash flow report. Joe's nominal Net Worth (which subtracts the HECM balance as well as his tax liability) peaks in 2046 at $555,298 and steadily declines from there.
