I am not an investment expert, but wouldn't you be able to do basically the same thing buying tax free municipal income bonds through an online broker and make over 6% tax free? I used an online brokerage with a low monthly fee and the minimum purchase was $20.  If you needed to you could sell small increments, but it takes a week or so to get your money.  Every month there is the dividend that you can reinvest. It seems more profitable that way, and a lot less record keeping.
