You listen! duh! end post...
Just kidding guys, well sorta. I recently learned about this really cool app that allows anyone, with a public library card, to download/checkout audio books, including real estate books. The app is called "OverDrive" and should be downloadable on most major app stores. OverDrive allows you to link up to your county library and checkout Ebooks and audiobooks. OverDrive stores these books in the app and once downloaded, you can even listen offline. My library allows me to checkout up to 15 titles at one time, but I think that depends on the specific county library. Each Ebook or audiobook can be checked out for 3 weeks, I also think that is going to depend on your specific library. Not all books ever written are at your library, and even books that are there, may not have an audible version; but this app allows you to easily request books through your library. The more requests there are, the more likely the library will purchase that title.
A couple downsides are that the app is not the most user friendly, but it's not the worst I've used, and there tends to be a wait list on most major titles.
Overall, I can't justify paying for an audible.com account, and I hate sitting down and actually reading. OverDrive is a really good alternative to be able to listen to a lot of books for free.
I hope some people benefit from this post. I am not affiliated with OverDrive in any manner at all. This is just a friendly suggestion for anyone looking for audio books, and doesn't want to pay for a service.
