Self Directed 401k Loan in LLC Question

[Tyler Herman]

So if I setup an LLC, setup a self directed 401k, transfer money from traditional IRA into the 401k, use that to take out a 401k loan of $50k, how does that work with crossing streams and tax conflicts?

Can that money be used for renovations on a property within the LLC?

Can that money be used for renovations on a property I bought in my name via conventional financing? This is the one I'd probably do first if that's not a conflict.
