Well, this is a nice windfall — and I wouldn’t presume to give advice without knowing a lot more about your situation. I doubt you will spend it all in your lifetime, so I’d ask about your spending plans– but also about whether you have made plans to leave the balance to someone or several people. That means having a will or Revocable Living Trust –and healthcare powers of attorney, etc.
You really need a FIDUCIARY fee only financial planner to look at your entire situation. And you canfind one you can trust at www.Wealthramp.com.
You can trust the planners as they are carefully vetted. Se up a meeting with one or two of them. The first meeting is free. And then write back and tell me what you learned and what you decided.
