I did this a couple of years ago with a Tax Attorney based in Chicago. His name is Lee Jennings with Dana Consulting Group. Phone is 312-332-7733. Website is www.danaconsulting.com.
Lee normally does these for individuals who leave their company, want to take their pension, 401K and/or IRA and use that money to start a business. My situation was the first time he set this up for real estate transactions.
Before I purchased my first park with this set up, I was able to get Lee on a conference call with John Hyre. John was able to make
recommendations that will greatly reduce my tax exposure when I sell the park.
