Its easy to read foundation books on a subject and think that you haven't learnt much, because it all makes sense and confirms your own opinion. Whilst I found myself doing this with this book, I recognised that there is a well balanced coverage and rounded content in here. It doesn't go into tremendous detail about individual areas, for example a tax advisor might identify some pros and cons of your particular circumstances. However, it does include some excellent guidelines.
I found it very reassuring to start with the characteristics required to get into this type of business, and check whether you have them. There were also quick tips about how to calculate if the rent will provide enough cash to cover costs, the higher yields from different types of property, and comments on refurbishment versus lost rent.
Like most of these books, it doesn't highlight all of the potential pitfalls in the business. The author has amassed a 3 Million pound property portfolio in a few years of booming house prices, but anyone starting now has to look to the longer term for substantial payback.
