The only advice a senior who has seen it all can give is this. I have had/seen all types of investments, advisors and touts over the years:
Be patient, you can get close to 5% in a money market fund now and you can withdraw as you see fit. One year CD's can yield 5.5% now, also.
Find yourself more than one financial planner and compare. No law against using two or more.
Learn the ins & outs of all investing yourself. Don't rely on ANYONE else, solely, remember, they get paid to play with YOUR money and still get paid even if you lose it all...........take some basic courses in investing in stocks, mutuals & bonds & real estate.
Diversify, even if some of it is in rare coins or art, etc. Many times these sectors do better than traditional investments.
Remember that you are not a bank when others need cash and try to take advantage of your position.
And, finally, and I am saying this only since you are a member here, and we all have a propensity to gamble. Try to be the rare breed, the 10% or so of us who truly gamble for just a hobby. Try not to make your killing betting on sports, keep your wagers at a very reasonable level.
Good luck to you, I am very happy for you & your family.
