Help me figure out the Solo 401K Real Estate procedure

[David B.]

I appreciate everything I have read here about buying investment real estate with a Solo 401K, but am still a little confused about a couple things that I haven't read about.

First, I own a Sole Proprietorship which my wife helps with. Most of our current IRA investments are in her name. Can we roll her IRA into a Solo 401K attached to my business?

Second, I'm a little confused about how the accounts are structured. The advice here that makes the most sense to us is to keep "the accounts" separate for ease of accounting. Does this mean separate Solo 401K accounts, or separate bank accounts? Can we have two separate Solo 401Ks or is just one allowed between us? Or is there any simple way to combine her larger IRA money with my smaller amount, or do we just use hers and leave mine in my existing IRA?

Third, I am about to change the structure of my company from a Sole Proprietorship to an S Corp. Should this be done before setting up the Solo 401K, or doesn't it matter?

Thanks a lot for any help with figuring all this out.
