401k to solo 401k from previous employer

[Kumar Gaurav]

Hello

I have 401k from my previous employer and instead of maintaining a SDIRA I wish to invest in real estate perhaps on a owner occupied multi family if that's feasible( if not at least on an investment property,) I also currently own a rental income property and also planning to start an LLC for software consulting with one or more employees.i would like to know what would be the best way for me to strategize so I can invest in real estate using 401k from my past employer.
