Article Body:
Adjustable rate mortgages (ARMs) can be as tempting to home buyers as carrots are to bunnies. The key to determining if an ARM is advantageous lies in the rate index used.
Understanding Rate Indexes
Lenders are eager to attract your business and often create appealing loan products to do so. Sometimes, they offer ARMs with very low initial interest rates, luring you into considering homes beyond your budget. However, these rates often rise sharply after six months or a year when the rate becomes linked to an index.
Indexes Explained
An index is a calculation of general interest rates across various financial markets that banks use to set your loan’s real interest rate. Common elements in these indexes include six-month certificate deposit rates, LIBOR, T-Bills, and more. Here’s a breakdown:
1. Certificate Deposits (CDs): CDs are fixed-period investment products from local banks. You deposit an amount for a set time (e.g., six months) and receive a guaranteed interest rate, such as three percent.
2. Treasury Bills (T-Bills): Known as the federal government’s credit cards, T-Bills involve significant national debt and corresponding interest rates used to calculate ARM rates.
3. Cost of Funds Index (COFI): This average represents interest rates used by banks in Nevada, Arizona, and California.
4. LIBOR (London Interbank Offered Rate): Despite its London origins, LIBOR is a common index for ARM rates. It reflects interest rates international banks charge to borrow U.S. dollars in London, causing potential fluctuations in your mortgage rate.
Why Indexes Matter
Indexes are crucial because they form the base of your loan’s interest rate. Suppose you apply for an ARM based on the LIBOR index, which is at 2.2% when you apply. This serves as your starting rate. If LIBOR increases by 1% in eight months, your loan rate will rise similarly.
It's important to know that the index rate isn't the final rate you’ll pay. You must also add the bank’s margin, usually 2-3%, on top of the index rate. For example, with a LIBOR of 2.2%, your initial rate would include this margin. Therefore, closely reading loan documents is crucial to fully understand the terms.
In conclusion, while adjustable rate mortgages can offer initial savings, it’s essential to comprehend how their rates are determined. This will help you make an informed decision and ensure you’re not caught off guard by future rate hikes.
