Jr. Bene Buyout or Judgement Lien Buyout?

Hi all,

I love the site, I was referred by an alumnus. I currently work full-time as a Realtor's assistant for a very successful agent, but to my surprise he does not know anything about investing in RE. I have always wanted to learn and to get my feet wet I want to start out with either the a.) junior bene buyout or b.) judgement lien buyout. Which would you recommend and why?

1.) Could one or both techniques be used during any time in the real estate cycle?

2.) Also, what is a typical ROI for each? If I pay $30k for a buyout could I double my investment (net)? If so, in how much time (6 months - 3 years)?

Before I spend the money on a class I want to hear people's thoughts and experiences and see which one is right for me. Thanks for your time.
