49 y.o. has 460k in 401k, 115k vested portable pension, 100k tree farm, 65k ROTH, ~200k in brokerage/metals/hard assets, paid off home worth ~180k, wife 401k=~40k. No debt to speak of. Daughter to start college this Spring, son started HS this Fall. Can I do it at 55? I would like to walk at 55 w/ the portable pension which will be worth ~175k then all the time adding 28k per year via 401k & Roth (both with catch-ups added). Make ~ 100k/year now and would only care to work part time at 55 still making good money (~50k working 6 months tops/year). At 55, daughter will have finished bachelors, son will be in second year of college. He is brainiac and I suspect he will get very good scholarships. I am blessed w/my kids.
