@kiddie it depends on how comfortable one is on managing the lump sum money.
It took us years with our financial guy to put all our pieces in place – it was with a plan and not too drastic with each move. For example, we first consolidated all our loose Sar-Sep, IRA, Roth, etc all under his financial group. Then we moved IRA to Roth IRA. Then we started buying annuities when the market was right for such. I still manage DH’s work 401k - company pays the fees; they have good investments and we have done well with the choices we have made.
It sounds like you have other financial pieces to perhaps look to finding a financial advisor; and you have some time before making the pension decision. I have a friend who has 100% survivor of her DH’s pension and they have kept with the pension. Many pensions are only 50% survivor. So look into details of the pension and also ask around with friends/coworkers to find the right financial person for you.
We attended a seminar (we paid for materials) 5 years ago where our financial guy was the instructor. We have been working with our fellow since then and have been meeting with him twice a year and attending the company information sessions “state of the market”. I have two graduate business degrees and he knows lots of things I am not interested in researching and learning. This is what he does for his clients and his company will be here - solid person and company. He also has been good over the years for DH to understand it all. Now that DH is retired, he looks at the financial picture often.
