Just been looking into municipal bond funds lately and stumbled on a few that seem worth checking out if you're into that kind of thing. Basically these are funds that invest in bonds issued by states and cities - the interest is tax-free federally, which is pretty nice if you're in a higher tax bracket.

So I found this list of municipal bonds for sale through different fund managers, and three kept popping up as top-ranked options. Goldman Sachs High Yield Municipal Fund (GHYAX) has been pulling in around 4.9% annualized returns over three years, with most assets in miscellaneous bonds. Then there's Fidelity New Jersey Municipal Income Fund (FNJHX) - that one's more focused on investment-grade securities and returned 4.7% annualized, with a pretty reasonable 0.45% expense ratio.

The third one everyone mentions is Vanguard Limited Term Tax-exempt Fund (VMLTX). It's more conservative with 3.8% returns and focuses on shorter maturity periods (2-6 years), which apparently makes it less volatile. Fund manager Adam Ferguson has been running it since 2017.

All three have that Zacks #1 ranking thing, so they're supposed to outperform their peers. If you're looking for steady, tax-free income without too much risk, these seem like solid options to research. Anyone else have experience with municipal bond funds?
