Our pathway to FIRE is going to come majority from rental incomes. The 4% rule really doesn't apply, but I like to play with it because it's a decent metric to compare to. Anyhow, calculating our return on rentals, adding in my wife's small pension, plus the modest amount of investable cash and doing the calc to see how much money that would represent in a 4% WR gives me a number I'm sorta pleased with.

But today, I thought, well, what about the money my tenants are paying towards the principal on the rental mortgages, should I include that? Figuring up the average principal payment times the number of houses times 12 and then times 25 gives me another semi pleasing number. Add the 2 together, and it made me feel pretty good. Would you agree with that calculation?
