Each week Bankrate.com posts the financial analysis of 6 mortgage experts from across the country. If you don't have an expert in your area you consult with on these topics, it's a great way to educate clients about the trends for interest rates.
Now, lest someone accuse me of being an ego maniac, I am one of the contributors. Nobody handed me the position, it was earned by constantly monitoring the "on the street" activity and providing valuable commentary. It's something anyone can do with enough dedication and research.
I hope this helps you grow your business,
