Consulting with a trusted Financial Planner is a good idea. I think you'll gain valuable insights into asset allocation, aligning your financial goals with a plan that will leverage your assets in a prudent way. I think most people don;t have a good idea of what a realistic rate of return will be with a well balanced portfolio.
You probably have a very good understanding of Stocks, Bonds and other investment vehicles adding a Great Financial Planner will increase your likelyhood of identifying good investments that will eneventually make up your comprehensive plan.
I wish you Success and Conngrtulate you on your upcoming retirement!
