Any reliable sources for projecting future interest rates?

[Joe Derobertis]

Hey everyone,

  I'm a new Real Estate investory, haven't purchased anything, but am lining up financing.  Because of some previous issues I am in a situation where I only qualify for a portfolio loan which will come at a 6% interest, fixed for 5 years and then adjusting every year thereafter.  It will have 2 points and no prepayment penalty.

My first though was okay well in the next few years I'll be able to refi out of this and into a conventional mortgage and life will be good.  However, life may not be good if within the next 3-5 years interest rate soar up above 6%.

So that got me to thinking on whether or not there is any reliable data out there on forecasting future interest rates.  Any ideas?  If done some google searching and haven't found anything that jumps out at me.

Thanks!
