Thirty-Year Fixed Rate Mortgage ( 30 yr)
The traditional 30-year fixed-rate mortgage has a constant interest rate and monthly payments that never change. This may be a good choice if you plan to stay in your home for seven years or longer. If you plan to move within seven years, then adjustable-rate loans are usually cheaper. As a rule of thumb, it may be harder to qualify for fixed-rate loans than for adjustable rate loans. When interest rates are low, fixed-rate loans are generally not that much more expensive than adjustable-rate mortgages and may be a better deal in the long run, because you can lock in the rate for the life of your loan

Twenty-Year Fixed Rate Mortgage (20 yr)

The 20 year fixed mortgage is a simple loan program, just like it’s much more popular relative the 30 year fixed. This fixed rate mortgage is a home loan with an interest rate that remains the same throughout the 20 year term. At the end of the 20 year repayment period, the loan is fully amortized. This means that the total principal (the face value of the loan) has been paid off in full in multiple installments. This kind of mortgage can be especially beneficial to those borrowers who prefer to forgo 30 year mortgage, but find the 15 year term too high of a monthly payment. In this type of mortgage, the borrower not only pays less interest over time, but typically obtains a lower interest rate than with a traditional 30 year mortgage.

Fifteen-Year Fixed Rate Mortgage ( 15 yr)
This loan is fully amortized over a 15-year period and features constant monthly payments. It offers all the advantages of the 30-year loan, plus a lower interest rate—and you'll own your home twice as fast. The disadvantage is that, with a 15-year loan, you commit to a higher monthly payment. Many borrowers opt for a 30-year fixed-rate loan and voluntarily make larger payments that will pay off their loan in 15 years. This approach is often safer than committing to a higher monthly payment, since the difference in interest rates isn't that great

Annual ARM
This loan has a rate that is recalculated once a year.
