Looking for advice and tips to take my portfolio to the next leve

[Chue Kue]

Hello, my name is Chue and I am looking for any tips and advice that can help me take my real estate portfolio to the next level. I'm a buy and hold investor. I currently have 3 single family home in MN that I am renting out to section 8 tenants. My goal is to create enough passive income to become financially free. I'm willing to try multi family investing since the real estate market where I'm investing has gone up in price. Thanks and let me know if u want to connect.
