Query: Not realistic in todays market

The fundamental problem with this book is, it assumes you can buy a property for 100K, and get $1000 a month in rent. That's just not possible anywhere in America. Where I live 500K gets you about $2000 a month in rent. About 400K gets $1000 a month. Because the books hinges on these numbers it's really quite useless.
