Best way to pull out retirement funds for investing

[Ross Yeager]

There are several posts I've seen asking about whether or not it's a good idea to pull retirement funds out for REI. I've seen arguments for both sides and I'm looking to do this in the most tax efficient way.

I have several BRRRR properties and am continuing with that strategy. The returns I can get on those are much better than my retirement fund and I'll be able to be tax efficient with those investments. My properties are purchased through my LLC which this year in particular will have a lot of business write offs due to an influx of expenses this year and I am the sole owner so the LLC acts as a pass through tax wise.

Has anyone here done this before? How did you go about doing it and were you able to leverage any business tax situations to help reduce the early withdrawal taxes/penalties?
