What is a good web site to find out the present market rate for loans for real estate?

There are sevreal indexes that are used by different lenders and different lender programs. Such as the, COFI (Cost of Funds Index), COSI (Cost of Savings index), LIBOR (London Interbank Offered Rate), CODI (Cost of Deposits Index), and the MTA (Monthly Treasury Average).

Be aware of what index your program utilizes as some seem to be more stable than others for a variety of reasons.
