YES! And I am not ashamed to share my thoughts (Dave Ramsey hates annuities). My life is very unique and it makes sense for MY situation. I researched this to the nth. degree about 5 years ago and I did not change my itinerary.
It seems a few years ago thoughts on annuities turned a little more favorable IF you have certain circumstances. One of them I remember is if you don't own a lot of assets (me). I've been contributing to my TIAA portfolio "guaranteed" portion for 40 years and annuitized it last year. For my longevity, I get an 18% bonus. I annuitized about of my portfolio and my "guaranteed" income with Social Security will be more than my current working salary. I still have close to 7 figures in my investing portion. Cake and eat it too, in my opinion. If I die, it transfers to my wife. If both die, the remaining money goes to my kids up to 20 years after start (by then I will have spent most of it out).
It's a personal choice and how you regard risk. My very diversified plan has built-in safety and still ample immediate cash available (six figures). There are no silver bullets and there are many ways to the same ending (enjoyable retirement followed by death). There are many pros and cons. Worry free sleep if the stock market crashes vs. lesser gains long term. You DO pay for this "insurance". There's lots of numbers to crunch for YOUR situation. Keep an open mind, beware of internet opinions, and don't believe everything Dave Ramsey preaches.
My TIAA program does not pertain to starting an annuity late in life. Talk to LOTS of advisors and compare notes.
EDIT: Racer4, you should be talking to an advisor about managing taxes post retirement, RMD's, Roth's..........all sorts of stuff to maximize retirement income/minimize $$ to Uncle Sam. It's mind boggling and I can not do it alone.
