I have rental income that I expect to cover anywhere between 50-75% of my RE spending, but I'm currently setting up a Money market cash buffer of 2-3 years of expenses, and leaving everything else in equities.
I'm also in OMY syndrome; hubby is scheduled to RE in about a year, and I'll stay put for another year (or two), depending on how comfortable I feel. We could both RE right now and be totally fine, but I'm the one who worries the most about the planning, so I'd rather have too much than not enough, and my new side project is trying to find a better option for the healthcare piece. I also actually enjoy where I work, so its not an issue for me to continue at it a bit longer.
Of course, once hubby RE's, I may feel differently, but I feel confident that my stretch goals/safety net will be fully actualized by the time hubby RE's, so hopefully it can help me feel more empowered to cut the work cord, maybe about a year after he does.
