Do I have to leave my current employer to roll over my 401k to a SD IRA?

See more at the following link: https://www.biggerpockets.com/forums/51/topics/679...Please see the following regarding general considerations with regards to investing retirement funds in real estate: If you are self-employed with no full-time w-2 employees, you can set up a Solo 401k & rollover funds from a non-Roth IRA as a tax-free direct rollover and then invest in real estate.Solo 401k vs.

I am a real estate investor who has decided to roll over on a little more than 5 million in homes.

With my LLC I just have it roll over to my personal taxes anyways, so there's no difference on the tax side as far as I'm aware (I'm not a tax professional though)

A seller carry back won't give them the cash for the rollover. 

I do have a few accounts available and I think it's fairly easy to rollover into a Self Directed IRA using a custodian.

I’m asking because I have funds in a 401k from a prior employer that I want to rollover to a SD Solo-k but not quite ready to start buying RE and don’t want to have it sitting earning nothing as I’m currently averaging 13% ROI with 12 month returns as high as 20%; however, it would be nice to have the funds positioned so I can access them quickly if I need to pull the trigger on a deal. 

The only reason I'm thinking about the rollover from the 401k is that I am no longer employed by the company that I have it out with and a lawyer in our REI club was discussing those that he has worked with and how well they are doing (20%-25% Return on investment).

An IRA is broadly applicable and could accept a rollover from a TSP.  

Mom and pop tenants you have to underwrite them very heavily as risk is higher for roll over and not much money to collect even with personal guarantee if they are single unit operator and have very little net worth.The starting auction price is usually nowhere close to the final bid price and that is much higher.
