Have you tried searching using iTunes?

You can find BP podcasts on iTunes.

Now the site asks me to go to iTunes and I am having difficulty in accessing.

Back when I first had the thought of investing in RE I did a search on iTunes for podcasts on Real Estate and you can guess what I found.

Your willingness to share your experiences and systems with us is priceless.  1 years ago, i stumbled across the BP podcast in iTunes and since then have been focused on my REI education.JoshBP Meetup in Big Bear anyone?
