Rollover Traditional 401k into Solo 401k after First Property

[Karla Parraga]

I have a full-time job and my employer offers traditional 401k. I have read a lot about the advantages of self-directed 401k, especially for REI. I would like to know if I can open a self-directed 401k when I buy my first owner occupied multifamily property, as this would also be my investment property. Also, can I rollover the funds of my old traditional 401k into my new self-directed 401k?
