What's the best loan for you? There isn't a single or simple answer to this question. The right type of mortgage for you depends on many different factors:

• Your current financial picture.
• How you expect your finances to change.
• How long you intend to keep your house.
• How comfortable you are with your mortgage payment changing.

For example, a 15-year fixed rate mortgage can save you many thousands of dollars in interest payments over the life of the loan, but your monthly payments will be higher. An adjustable rate mortgage may get you started with a lower monthly payment than a fixed rate mortgage -- but your payments could get higher when the interest rate changes.

A Fixed Rate Mortgage is the most common type of mortgage program where your monthly payments for interest and principal never change. Property taxes and homeowners insurance may increase, but generally your monthly payments will be very stable.

Fixed rate mortgages are available for 30 years, 20 years, 15 years and even 10 years. There are also "biweekly" mortgages, which shorten the loan by calling for half the monthly payment every two weeks. (Since there are 52 weeks in a year, you make 26 payments, or 13 "months" worth, every year.)

Fixed rate fully amortizing loans have two distinct features. First, the interest rate remains fixed for the life of the loan. Secondly, the payments remain level for the life of the loan and are structured to repay the loan at the end of the loan term. The most common fixed rate loans are 15 year and 30 year mortgages.

During the early amortization period, a large percentage of the monthly payment is used for paying the interest . As the loan is paid down, more of the monthly payment is applied to principal . A typical 30 year fixed rate mortgage takes 22.5 years of level payments to pay half of the original loan amount.

An Adjustable Rate Mortgage may save you money early on, but there can be risks involved since their rates are tied to various economic indexes.

A few options are available to fit your individual needs and your risk tolerance with the various market instruments.

ARMs with different indexes are available for both purchases and refinances. Choosing an ARM with an index that reacts quickly lets you take full advantage of falling interest rates. An index that lags behind the market lets you take advantage of lower rates after market rates have started to adjust upward.

The interest rate and monthly payment can change based on adjustments to the index rate.

6-Month Certificate of Deposit (CD) ARM
Has a maximum interest rate adjustment of 1% every six months. The 6-month Certificate of Deposit (CD) index is generally considered to react quickly to changes in the market.

1-Year Treasury Spot ARM
Has a maximum interest rate adjustment of 2% every 12 months. The 1-Year Treasury Spot index generally reacts more slowly than the CD index, but more quickly than the Treasury Average index.

6-Month Treasury Average ARM
Has a maximum interest rate adjustment of 1% every six months. The Treasury Average index generally reacts more slowly in fluctuating markets so adjustments in the ARM interest rate will lag behind some other market indicators.

12-Month Treasury Average ARM
Has a maximum interest rate adjustment of 2% every 12 months. The treasury Average index generally reacts more slowly in fluctuating markets so adjustments in the ARM interest rate will lag behind some other market indicators.

The best way to find the "right" answer is to discuss your finances, your plans and financial prospects, and your preferences frankly with a mortgage professional.
