This thread is so old, I may have said this before, but it bears repeating. You don't have to make $100K to get to FIRE. I never did. DH never did. Together we're FI and I RE'd three weeks after we got married almost eight years ago, so there was really no period where we were both contributing to a huge combined number.
Except last year, we blew it. We flipped a house, which is our idea of fun, and it pushed our gross income over $200K for the year, even after we stuffed the max into DH's 401k. We were shocked that we couldn't do a Roth. What?? We even had to defer the deductions on our rentals. Huh?
Kind of funny that the big bucks came well after FI(us)& RE(me). It was kind of a one off and not likely to be repeated, especially because DH can retire in about six months and probably will. I doubt we'll tackle such a huge flip again.
