Payments Annuity

I am looking to retain ownership of principal and no loss to principal value of a million dollars. I also seek current monthly income that could either be tax free or not, but preferably tax free. Wondering if there is a better method than the tax-free money market mutual fund to achieve higher return as rates are low, but still have principal and most importantly current monthly income. I am not looking for an annuity, again ownership of principal. Thank you in advance.
