If this will be your first Malibu home or a "transitional home" -- one you plan to own for a short time, an ARM may be the best type of loan. If it's going to be your dream home or one you plan to raise a family in, then you may want the stability of a fixed rate mortgage. If you choose an ARM, the index should be based on the Cost of Funds Index if rates are increasing, and Treasury Bills if they are decreasing.

The COFI's are less volatile over time than T-Bills; make sure the teaser rate is understood and what the real rate would be.

Whichever loan you choose, make sure that you scrutinize all the closing costs. If you are required to have a mortgage escrow account and private mortgage insurance, make sure you understand the terms and cancellation procedures. Also, make sure there are no prepayment penalties so that you can utilize an accelerated mortgage plan. A good mortgage reduction plan can save you tens of thousands in interest costs, and shorten your loan term, with only small extra principal payments. If you experience negative changes in your job, health, or marital status, you can revert to the standard payments in your mortgage contract.
