Tax lien certificates investing

[Jeffrey Bass]

I am reaching out see if anyone can point me in the right direction for investing in tax liens. I have some money sitting around and want to put it to making money. I just purchased my first condo for rental property and don’t have enough for a second property right now. Any suggestions. Also looking for information on covered calls with stocks if anyone has ideas with stock market. Know this is off topic but anything helps. Keep investing. Thanks.
