I found the MMM blog just under three years ago. A few months later I came up with a financial plan that would permit my wife, who just turned 62, to retire from the Post Office four years early. She would defer both her SS and 401K until later, preferably age 70, as we should still be bringing in more than enough income to make end meets and continue saving given my new job, her pension, and two smallish rental units.
This month we passed one of those last key milestones, we paid off the mortgage on the second rental which frees up 1500 per month (we were prepaying the mortgage). With that cash flow now secured she will be set to retire in 70 days, and I will hopefully be eight years behind her (I turn 50 this year and would like to be done at 58).
When I took the new job I started working significantly longer hours (with significantly better pay) and have become sloppy in my spending habits as a result, harder to optimize when time is at a premium. With the missus retired we should be able to start optimizing as I had been when we first found this blog. The long term goal will be to hasten my retirement, which is still too far away at this point to forecast accurately.
