"Simple Real Estate" - Investing in Tax Liens

[Andrew LeBlanc]

Yesterday I attended a free seminar put on by "Abundance EDU". There I ended up paying 2340$ US to join an affiliate company (Simple Real Estate) that aids in purchasing tax liens in the US; their site and support team will help me analyze the homes attached to these liens, and lower the risk of acquiring a property in poor condition.

I'm 25 and work full time. My parents (who did not attend) are telling me that this may be an overly aggressive investing strategy, and that I could be spending a lot of my time and money in a system that could be flawed. 

I need advice from people who have invested in tax liens in the US! Should I pursue this?

Thank you.
