On the other hand, if you are the type of person who will be up at night worrying about where interest rates are headed, then you may be better off choosing a different type of loan product - one that is not based on Libor rates.
When you obtain a LIBOR-based mortgage loan, your interest rates will not fluctuate every time the LIBOR fluctuates; instead, your interest rate will fluctuate at predetermined intervals as set by the terms of your loan.
The format of their data, however, may not be as easy-to-use as the formats used on various financial data websites.A good place to start for Libor rate history is the website of the British Bankers' Association (BBA).
Although many lenders follow a certain index - whether it's the Prime Rate, the LIBOR, or some other index predetermined by the lender - it is up to each individual lender to decide how much to add to each index.
Some lenders tie their interest rates closely to an index such as the Prime Rate or the Libor plus a predetermined margin, but the choice is ultimately up to the lender to decide what interest rate to charge.
Although many mortgage companies base their interest rates on the Federal Prime Rate, Chase Home Finance bases their mortgage interest rates on the London Interbank Offered Rate, also known as the LIBOR.
For example, the LIBOR rates from the prior day are published each business day in the Money Rates table in the "Money & Investing" section of the printed and online version of Wall Street Journal.
It is also important to keep in mind that just because a financial institution offers loans based on the Libor it does not necessarily mean that the Libor rate is the actual interest rate you will pay.
When it comes to adjustable rate mortgages - whether the index is the LIBOR, the Prime Rate, or some other method - there is no concrete way to ensure the lowest interest rate for the life of the loan.
If you are looking for the historical Libor USD, you are looking for the Libor rates which reflect the interest rates for inter-bank lending of United States Dollars in the London financial market.
