posting this mainly to just keep a record of it for the future
this is the ETF for the intermediate term national municipal bond fund (VTEBX) (I think an intermediate term is more prudent because as yields rise, longer term bonds that were initiated within the past decade at our historically low rates will fall in value)
at this time the all time high to the all time low is only a 6.7% range and that range took almost 5 months to move that range.
that is very steady and it currently produces about 0.094/share of tax free income per month (5 month average) which is only about 2.22% but that is equivalent to a higher taxable yield depending on your tax bracket and state
low expenses at 0.09%
could be a good investment for someone looking for stable monthly income, or a lower risk investment that has the potential to yield more than the savings rate at even the best online banks (for now)
