But I bought a kindle on sale on Black Friday last year and I mostly download business, real estate, and self help books onto that at half the price of hard copy books.

It is on Amazon via Kindle and is short (~50 pages) but gets to "the point" and gives some really high impact points.

Every real estate investor should know everything in this book, "50 Real Estate Investing Calculations".I prefer to have all my books on Kindle so I can access them anywhere in the world on-the-fly.When you first look at a property for sale the numbers always look boring and the basic numbers at the time of the purchase are meaningless.

I paid for many real estate courses and always found that the advertising hype is always far better than the course and I never went to a real estate seminar or real estate course where they taught something I didn't already know and never went to a real estate course where you can't find what you need to know by buying Kindle books on Amazon for about $20.What I am going to say is a fact.

I Downloaded the Alexa app on my phone, and the Kindle app, so every time I buy a book at amazon in kindle format, I can ask Alexa on my phone to read it to me.By listening the book while you read it on the app, you can concentrate more, retain more, and keep a longer time focus on it.

Forgot to cancel my free trial for Kindle.

It's $15.40 on Amazon, even cheaper on Kindle.

I am always looking for better ways to do the math.I like to go with Kindle since I can carry all my books on my cell phone or a tablet. 

Little tip, get the kindle version.
