Using 401k to purchase real estate

[Kyle B.]

I recently left my job where I had a roth 401k (so my contributions were made after tax). Does anyone know if I am able to roll this account over into some kind of self-directed IRA where I can use the funds for real estate investments (I'd be looking to do home flips in this case).

Additionally, since my contributions were made after taxes, could I withdraw this money penalty free and without having to pay any additional taxes? Is that correct, has anyone been able to do this before? Obviously if I withdraw from my growth and/or company contributions, I would have to pay taxes on that (and possibly a 10% early withdrawal penalty), but is there a way to distinguish between the two when taking a withdrawal?

Thanks in advance!
