Currently, about 80% of my financial value is invested into a 529 plan for college. As I understand it, this gives me a decent rate of return (in terms of interest), and is tax free IF I can prove the money is being withdrawn for educational purposes. A very tiny portion of my income is devoted to a 401k, and the rest is disposable. I think that the 529 plan is good because education is my immediate need (and financial drain). But I am wondering if there might not be another plan or investment strategy available that will give me a greater rate of return.
