BAMP!
I hit 75%, for now.
I bumped up TSP repayments (loans were for debt consolidation and bigger house down payment) to put $1600 (over half my FT gross) into the market, happily coinciding with the first paycheck of Stocktober. Take-home is now only 34% of gross. I laugh every time I see my check... thinking of knocking it down to three figures just for bragging rights.
I added a small TSP deduction from my drill pay, because my deductions from FT work process so slowly (multiple pay periods! WTF!?) that I gave up trying to calibrate it to max out exactly. I now take home $700 from drill, offset by $333 invested monthly in a rental partnership and almost $500 in automatic principal payments. This puts my after-tax SR at 67% before any other debt payments. Since I'm selectively killing a handful of small 0% deals as they expire, the payoffs are erratic but I need $520/mo there to hit 75%. With my average running closer to $1K, I'm probably near 80%, though I'm not accustomed to this territory to know how easily I'll be able to stay put here. Impending family visits and holiday travel may lead me to slack off slightly, but the deep winter will be a festival of frugality - cocooning with the wife and dogs, cooking in mass quantities, and spending very little.
Just touching the goal for a minute feels good, considering 50% was a pipe dream in early 2014. If I can hold fast... life will change very quickly as new options unfold.
