Rating: Medium to High Risk. Risk can be mitigated by selecting longer initial fixed rate periods.
Description: Adjustable Rate Mortgages, also called “ARMs”, typically have a term of 30 years. Unlike traditional 30 year fixed rate mortgages, the interest rate adjusts periodically after an introductory fixed rate period. For Fannie Mae and Freddie Mac conventional mortgages, the introductory rate is typically fixed for 3, 5, 7 or 10 years. Community Banks & other Portfolio Lenders often offer additional introductory rate periods of 1 or 2 years and shorter terms such as 15 and 20 years.
For Example: A conventional Fannie Mae 3 year ARM is a 30 year mortgage where the interest rate is fixed for the first 3 years of the loan, and then adjusts periodically– either monthly, semi-annually, or annually for the remaining life of the loan.
Generally speaking, the shorter the introductory fixed rate period, the lower the interest rate. Therefore a 3 year ARM would have a lower interest rate than a 5 year ARM, and a 5 year ARM a lower rate than a 10 year ARM. Almost all Adjustable Rate Mortgages offer lower initial rates than traditional 30 year fixed mortgages. This makes ARMs attractive to people looking for a lower monthly payment in situations where they are not concerned about the risk of the monthly payment adjusting and potentially increasing once it enters the adjustable rate phase of the loan.
Examples of situations where opting for an ARM might make sense include:
If you are considering an Adjustable Rate Mortgage, you will want to determine what happens once your introductory fixed rate period ends. You should inquire about the following:
To answer #s 2 – 5, you will need to understand what the following terms: Index, Margin, and Caps.
The ARM Index refers to the underlying base rate that an adjustable rate mortgage is tied to. The Index is typically a benchmark rate that banks use to borrow money from each other. Typically the Index is tied to the Libor Rate or the Treasury. These benchmarks are variable & adjust periodically according to market factors/forces. As industry rates go up, these rates go up. As industry rates go down, these rates go down. The Index represents the current cost a bank would incur to borrower money. Understanding the ARM Index is the first component you need to determine what your ARM interest rate will adjust to when it reaches it’s first/next adjustment.
The ARM Margin is a fixed % that is added to the Index to determine the total or fully indexed interest rate of an adjustable rate mortgage. The Margin is fixed for the life of the loan; whereas the Index is variable. The Margin represents the markup that the lender receives as interest above the current cost of borrowing money.
The ARM Rate Caps determine how much the interest rate can fluctuate each adjustment period. Typical caps are….. 5/2/5 or 6/2/6
You also may see caps expressed as…… 2/5 or 2/6. In this scenario the initial adjustment and subsequent adjustments are the same = 2%. The max adjustment over the life of the loan = 6%.
Example #1: If the caps are shown as three numbers: 5/2/5
Example #2: You select a 5/1 Year Libor ARM with an initial interest rate of 3% with 2/6 caps.
You calculate the proposed interest rate by adding the Index + Margin. The index- ie. Libor Index will vary periodically according to market factors. As industry rates go up, your index will go up. As industry rates go down, your index will go down. While the index varies, the Margin is unchanged and is an additional spread for the lender.
Example: If your index was 3.41%, and the Margin was 2.25%, your rate would be 5.66%. Note that the Index value will change from time to time, but the Margin will always be the same. In this case, 2.25%.
