Real Estate Investing For Dummies, 2nd Edition contains approximately 20-25 percent updated and revised content, including expanded coverage on the challenges and opportunities that accompany investing in a down real estate market. In addition to other general updates, Eric and Ray expand on the subjects of flipping properites -- a practice that they advised (and still advise) readers to approach with caution in the first edition, published at the height of the flipping frenzy -- and foreclosure investing -- today's "it" real estate subject that is too often portrayed as a get-rich-overnight proposition.
