What to Look for in a Tax Lien Investing Course

The first thing to consider in choosing a tax lien investing course is the curriculum. Is it comprehensive? Will it teach you what you need to know to start investing in tax liens? Is there student support from the instructor or mentors?

The second key component is the expertise and track record of the instructor. The instructor should have the experience to provide critical insights. The third component is the compatibility of the teaching method with your learning preferences and schedule availability.

Cost is also a consideration and any tax lien courses try to upsell you to courses that can cost $20,000 or more. While tax lien investing has the potential to produce substantial returns, you first need to test the waters. Combining a lower-cost course with your own research might be a better way to go.
