How do I punch in the mortgages on my rental properties in fire calc and the income I receive?
Why would you need to?
FIRECalc doesn't have any data on rentals, so it wouldn't mean anything.
I'd just figure out what your net rental income will be and subtract that from your expenses on the first page.
Barring that, you can have the higher expenses (include the rental mortgage), and offset it with extra income on the second tab.
It amounts to the exact same thing.
