I understand the concept but I would like to know if a 403B is ineligible for rollover if you are currently employed with the company that administers the investment.

Is it true that you can only do one time rollover from your SEP IRA into Solo 401K one time, whatever assets left in the Sep IRA have to stay there or can you make multiple rollovers?

I use Quest IRA but there are many providers.What was highly beneficial for me was that I got to rollover my 401k directly into my Self-Directed IRA so I didn't get slammed with any penalties.   

I also have the LL roll over on my rentals, but the bill comes to my house.

@Alan Feldman To clarify, you have 180 days to roll over your capital gain into an OZ Fund.

I also plan to roll over our old 401k accounts to these later too.Or, does each LLC's have to sponsor separate Solo 401k for me and my wife?

Likewise, If you have any Rollover IRA accounts, you can roll them over every year, granting a 60 day float. 

(My enrollment fee is good for 1 year of service).I explained at the time that my intent was to get a card or cards with 0% introductory rates, and then roll over my CC balances to new cards when the introductory rates expired in 12 months. 

As far as putting funds into Solo 401k, there are only two ways the 401k can be funded:1) Rollover from another qualified plan2) Contributions from earned incomeFunds from the refinance can never be placed into a retirement account. 

No roll over allowed anymore.
