Solo 401k better than SDIRA for my situation?

[Peter Morgan]

Hello,

With the stock market doing so poorly, the 401k from my old employer took a beating this year and I realized I did not have much control to take over any damage control. So I initially was thinking about opening an SDIRA but now I am considering Solo 401k and perhaps eventually invest in syndications but I don't own any business except for my rental property that I earn rental income.Would it be a good idea to open an LLC with myself as the sole employer and employee (perhaps my wife will join me once she gets into a consulting job) I am also planning to do some side hustles such as teaching part time in a University and working as a part time tech consultant. With this back drop is it a good idea to form an LLC and direct all of my rental income to the LLC as business income, are there going to be any tax advantages with this approach.

Appreciate your input on this.

Thanks
