I am 44 and DW is 40. 2 kids one will be college age in 6 years and another in 12 years. Savings thus far: 401K is $700,000 (mostly target retirement fund going out to 2040 target date), taxable account is at $3M, and 529 is at $125,000. A rental property nets $6K a year (after taxes and expenses). I take care of my parents (who live in a house and I pay the mortgage) and I have a house with a mortgage. Yearly expenses are $150K (with mortgage payments). I am targeting $175K in expenses (after taxes) to retire early. Investments are 80% equity, 15% fixed and rest is cash. I have used FireCalc. Job pays well and DW does not work. Job is more about keeping head down and building assets. Questions I have 1) how do you plan for college expenses, and 2) how do you account for a 50 year ER time period. Any comments are welcome esp. on planning and avoiding the one more year trap.
