Massachusetts is incredibly strict when it comes to fees for example, so the OP's state may be the same way.

The only obstacle for us, would be finding new and creative ways to find Buyers.We've already set aside a few days to spend at the Race Track.We are always willing to learn more and take on new effective approaches to marketing.

I purchased the book of all parcels, went through by zip code and identified the ones I was interested in (over 100) and watched as the auction date approached and they were all satisfied and taken off the auction list by the time the auction happened.

The deal clearly passes the 1% rule, it's actually a bit above 1.5% which I believe to be incredible in NJ.  2% is basically unreachable unless you find an absolutely killer deal.  

For all of the reasons cited in this post, and many more, we always advise our clients and customers to take a belt and suspenders approach to these issues.
