Saw on another blog references to " some real estate transactions can trigger the need for a 401k to file a tax return and pat taxes".Looking to use my solo401k to invest in real estate but want to avoid making a mistake.

Just be an expert at one thing at a time.I was in your situation for a long time and I never pulled the trigger until I moved to Des Moines-I can only recommend that you work hard to make connections (is there a REIA or Meetup there anymore-I used to go to the QC for them) and learn your market.
