Will likely roll over to it since it's in FL

I'm not an expert, but my understanding is that you can us a self directed IRA for rental properties, and if you later run a business that qualifies for a Solo 401k, you can roll over the IRA into a solo 401k as long as it isn't a Roth.

This doesn't mean that you can't roll over 401ks from previous jobs, or any IRA accounts with traditional brokerage firms you may have.

If I sell current house and just roll over the money to pay off construction loan, then plan is to use basement rent money to pay off other properties.

Has anyone used ROBS to start their business?  Sounds like a good way to get access to cash and invest in real estate.  Even get partners to invest and get shares.  Love to hear your thoughts.  I'm considering doing t...

I'm not going to roll over and play dead.

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. 

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

Businesses sponsor retirement plans as employee benefits.You can rollover existing tax-deferred savings into the Solo 401(k) as well as make new contributions into the plan based on income via your flip/wholesale LLC.The Solo 401(k) can invest passively in real estate, so long as those investments are kept very separate from the other personal investments you are making with non-retirement funds.When it comes to Solo 401(k) providers, there are document mills and true advisors.  

Does that 90 day notice to vacate roll over to me or would I have to give her a new 90 day notice when I assume ownership?
