UPDATE
I have a firm retirement date now, because my company offered a retirement benefit package, and I accepted it. I leave the company on July 1.
RECAP. I am 55, a corporate employee for 28 years, and I was considering retiring last fall, but I wasn't sure about LTC costs, because my DW has early-onset dementia, so I continued working. Meanwhile, I felt increasing tension between corporate life and caregiving responsibilities. While FIRECalc showed I could retire then, adding LTC costs at a private facility broke the plan. While I have the intention to take care of DW at home as long as possible, at some point the reality is, her needs would likely exceed my capacity. I have a place in mind that my father was in that we both like, and I know what it costs. Using that data, I have a plan now that funds LTC for multiple years, as well as early retirement.
I was working on a plan for retiring in September of 2026, but then another twist of fortune arrived, a "golden parachute" if you will, a retirement incentive package. This is like severance pay, and is a generous enough lump sum payment that I was able to accept the package and the closer retirement date. That is really the best outcome, since the lump sum helps with the LTC funding (along with other sources), and the timing is much preferred as with each month that passes, DW's condition requires more adjustments and greater responsibility.
More details on LTC funding. I do not have LTC insurance (and do not want it in its current form). Now with Health Savings Account, after-tax brokerage account, severance/retirement lump sum cash, DW's social security, DW's pension from the state govt, and HELOC, I have a total of 30 months of LTC debt-free, plus another 25 months with HELOC, without even touching my own retirement accounts, or selling property. That is enough for my peace of mind. We also made adjustments and have increased the rent income stream.
None of this would have been possible if I hadn't had FIRE on my radar for decades. I started off with a "free by 40" spreadsheet. LOL. Marriage, buying land, building a house for my mother-in-law, building a super-awesome greenhouse for my plant projects, lifestyle creep (moderate), all happened along the way, but I kept maxing out 401k year by year and I had age 55 on the radar for retirement (instead of 40!). Since I will still be 55 on July 1, it appears my goal will still be met, even despite everything.
I'm feeling fortunate (blessed even), and grateful for everything right now. TBH - being a caregiver for DW, as well as doing my gardening and greenhouse work, and being a landlord, is all I feel like doing and all I think I should be doing now.
I just have the next two months to ensure a smooth transition of my responsibilities and train my AI replacement (not even joking!). Meanwhile, my financial attention is shifting to smaller optimizations, like ensuring I capture remaining 401k matching contributions for the year, and figuring out how to minimize my tax bill for a high-income year.
