I bought a tax lien/tax deed course/membership and attended a 3-day workshop. I got lots of good information and although it was expensive I feel I got good value from it, and got to spend 3 days with the co-founder of the company, learning from his experience, which is priceless. The conclusion I came to is that tax lien/tax deed investing is difficult because of the tremendous variability of the rules from county to county and state to state. While some great deals can undoubtedly be had, I can see why many are intimidated by it and shy away, but for me this just means that there is an opportunity there for someone who is dedicated to learn it. From what I've observed so far, there are a few knowledgeable investors doing it and a whole lot of newbies who think they know what they're doing or think they can learn it by trial and error. I'm sure it's the old 80/20 rule: 80% of the good and profitable deals are had by the 20% who are savvy investors. The rest are just wasting their time and money.
