Safe investment options

[Paulo Correia]

Hello

I have cash (50k) that i would like to invest in a safe investment option. I've been trying to diversity my investment portfolio. I currently own multiple apartments, stocks, 401k, Roth IRA, HSA account (invested in mutual funds) . Now I'm looking for something safe, even if return in the investment is in the low since digits I'm okay with it. Anything is better than the % I'm getting from my savings account. Thank you all
