Self directed /solo 401K or self directed Roth

[Vaughn Funk]

Hi all,

I am getting ready to go through a divorce and am looking at getting about $250,000 from my wife's 403B.  I currently do not have a retirement account except for my retirement from the Navy.  I was told to set up a self directed or solo 401k so that the money can go directly into that.  I am currently a self employed Real estate agent but have had very little income the past 2 years because I went back to school for my MBA.  Any advice on which type of account I can start and get the funds into so that I can start investing in real estate?
