I have heard good things about John Beck’s materials available on this site. The taxsales sites are well regarded from many posts on the main newsgroup. Check these URLs out for more info as well as John Beck’s articles for free at CREOnline:
Joel Moskowitz’s book “16% Solution” is best. and well rpiced @ $24.95. Hendricks book and Lin Stone book’s are good but a cut below. JoHn Beck is excellent. The other tax sale.anything stuff is junk.
