Book excerpt: The previous edition of this book is The Complete Idiot's Guide to Real Estate Investing, Second Edition. The book focuses heavily on commercial real estate investing, but given the absence of the word commercial in the title and elsewhere within the book, it was purchased by many whose interests in real estate were of a much smaller scale and involved residential income properties, as opposed to commercial real estate development. The Complete Idiot's Guide to Commercial Real Estate Investing, Third Edition, is retitled and slightly refocused to better target the intended audience aspiring commercial real estate investors/developers. What little coverage of residential income properties that existed in previous editions has been cut, and the remaining content has been updated to clearly reflect the focus on buying and selling commercial properties.
