Why people don’t mention Tax Sale as a great ROI?

[Allison Nog]

We've been investing in tax deed for more than 2 years now and we've been experiencing a great ROI. We've made more than 800% profit in some deals and some properties we hold and are all rented.

Some of them we got the title insurance (the most expensive ones) and some we were able to sell recording a Quit Claim Deed only. All is going pretty well but we don’t see many people (nobody actually) saying about this amazing investment method.

I wonder why? To good to share? Too may myth about it? People that really understand are hired for banks and big investment companies??
