I'm 30, debt-free, make max contributions to my Roth IRA and 401(k) and have six months of living expenses in a high-yield online savings account. I live frugally and am gainfully employed.

At this stage, I'd like to take my saving to the next level by investing $500 to $1,000 a month. Ideally would avoid fees and research/active oversight. Would love to hear your thoughts on some secure, high return options!

As a side note, I'd like to buy a house and start a family within the next five years, but my partner and I are saving for that separately. This would be for my personal savings and maybe early retirement if possible. Thanks so much!
