Correlation of Bond Yields and Mortgage Rates

[Account Closed]

Hey smart investors, 

I was hoping someone could offer me valuable resources to better understand the correlation between bond yields and mortgage rates. I understand the general yin-yang that when demand for bonds increases, it pushes down yields and brings rates down with it, but I am hungry for a deeper understanding—a view behind the curtain of how the whole system works. I'm sure it's much more in-depth than I am ready for, but I want to try and learn this dynamic. 

Any links or articles you guys might know of would be greatly appreciated! Also, I would prefer any BiggerPockets articles, as I'm sure this has been brought up already, and I would appreciate the communities sense of the topic.
