Guide to Choosing a Tax Lien Investing Course

The first thing to consider when 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 many tax lien investing 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. 

Frequently Asked Questions

  • What Are the Benefits of Becoming a Certified Tax Lien Professional?

    The National Tax Lien Association (NTLA) is the trade group that represents investors, lenders, service providers, and government officials as it relates to tax lien sales. It is also the sponsoring organization of the only certification program for tax lien investors, offering a Certified Tax Lien Professional (CTLP) credential. While you don’t need certification to invest in tax liens, a CTLP certification provides you with a reliable assessment of your knowledge and skills. CTLPs are also hired by lenders, real estate organizations, and government organizations associated with the practice of tax lien sales.

  • Are There Prerequisites for Tax Lien Investing Courses?

    There are no prerequisites for tax lien investing courses. However, those with a background in real estate or foreclosures might be able to pick up on the subject matter more quickly. 

  • What Do You Learn in a Tax Lien Investing Course?

    After taking the course, you should know the essentials of tax lien investing in terms of the process; calculating the purchase price; understanding the bidding and redemption processes; knowing your legal rights as an investor; finding, identifying, and selecting tax liens; and reviewing the pitfalls of tax lien investing. 

    A good course can also provide insights into the rules, processes, and legal aspects of investing in specific states or counties. Some courses are specific to one or two states, which is fine if you plan to invest in those states; other courses try to cover more states. 

  • What Are the Risks of Tax Lien Investing?

    Tax liens tend to be higher-yielding investments, but they're also very risky. If the homeowner never ends up paying their property taxes, the tax lien investor risks owning a worthless property, dealing with foreclosure issues, and paying additional fines. Before bidding on a tax lien certificate, it's important to thoroughly research all the tax lien rules and processes in your county, as well as the current state and value of the property you're considering.

  • What Is the Interest Rate on Tax Liens?

    The interest rate on tax liens varies from one state to another, but it is typically between 10% and 12%.


Our initial research found about 20 websites claiming to be tax lien investing courses. However, after a deeper dive, we found that most were less instructional and geared more towards marketing, seeking to upsell people to a much more expensive course after taking a free or low-cost course. We narrowed our scope to those courses that are purely instructional with good reputations, reasonable pricing, and solid curriculums.
