Adjustable Rate Mortgages (ARMs)

Adjustable Rate Mortgages (ARMs)
These loans generally begin with an interest rate that is 2-3 percent below a comparable fixed rate mortgage, and could enable you to buy a larger home or a home in a more desirable area.

The interest rate will change at a specified interval (for example, every six months or every year). If the interest rates go up due to changing market conditions, your monthly mortgage payment will go up. Conversely, if rates go down, your mortgage payment will go down.

There are literally hundreds of adjustable rate mortgage programs to choose from.  There are, however, categories of  adjustable rate mortgage programs:

  • Amortizing ARMs
  • Hybrid ARMs
  • Hybrid Interest Only ARMs
  • Option ARMs

Before analyzing each type of ARM program category, it is important to understand the “mechanics” of an ARM.

Common ARM Terms

  • Index:  The index is the “moving” part of an ARM.  The index value will change over time, thereby causing the interest rate on the loan to change.  The index of an ARM is the financial instrument that the loan is "tied" to.  The indices move up or down based on conditions in the financial markets.  For an explanation of each of the most common indices and which may be best for you, contact your Freedom Financial mortgage professional.  The most common indices are:
    • Treasury Securities (these can be 6 month, 1 year, 3 year, etc.)
    • LIBOR (London Interbank Offered Rate – i.e., the European Fed Funds Rate)
    • Prime Interest Rate
    • Cost of Deposits Index (CODI)
    • Cost of Funds Index (COFI)
  • Margin:  The margin is a number that is determined at the time of locking in the interest rate or is determined by the loan program selected.  Unlike the index, the margin remains the same over the entire life of the loan.  Margins can vary based on the loan type and/or the index used, but generally range from 1.75% to 3.50%.
  • Fully-Indexed Rate:  This is the “real” interest rate on the loan.  Many ARM programs have “teaser,” or artificially low starting interest rates, to entice you to take the product.  Regardless of the starting interest rate, one should always pay close attention to the fully-indexed rate, as this is the real rate on the loan (excluding the period of time the teaser-rate is effective).  The fully-indexed rate is the sum of the index and the margin.
  • Caps:  Caps can either limit the amount the interest rate can change or they can limit the amount the payment can increase:
    • Interest Rate Caps:
    • Periodic:  These caps limit the interest rate increase and may limit the interest rate decrease for each adjustment period.  For example, if a loan is to adjust every six months, it may have a 1% periodic rate cap, which limits the movement of the rate to 1% every six months.
    • Lifetime:  This cap is MANDATED BY FEDERAL LAW.  Every ARM loan must have an interest rate cap that limits the amount that the interest rate can increase during the life of the loan.  Federal law does not limit the amount of the cap, it merely states that such a cap must exist.
    • Payment Cap:  This cap limits the amount a payment amount may increase.  Payment caps are usually set at one year intervals.  The most common payment cap is 7.50% per year.  In other words, if a minimum monthly payment is $1,000 during the first year, the minimum payment during the second year cannot exceed $1,075 ($1,000 x 107.50% = $1,075).
    • Recasting:  By Federal law, all loans must be “recast” after ten years and every five years thereafter.  When a loan is “recast,” the payment the borrower must pay is determined by the current principal balance, the current interest rate, and the term of the loan remaining.  On periodic interest rate capped ARMs, the loan is automatically recast by the natural terms of the loan.  On payment capped ARMs, the loan payment is adjusted at the time of the recast without regard to the payment cap.  In this instance, the borrower’s payment is likely to increase fairly significantly.

When a lender makes an adjustable rate mortgage, the lender chooses the index which most closely approximates the lender’s cost of acquiring money to lend out (i.e., the lender’s “cost of funds”).  Lenders cannot lend out money at their cost of funds, so the lender adds a Margin to the index, since the Margin is the lender’s profit, one can equate the Margin as a “profit margin.”  The higher the Margin the greater the lender’s profit.  Of course, the Margin also helps the lender compensate for greater risks, such as low credit scores, non-owner occupant properties, low or no income documentation, etc.

Caps (interest or payment) are placed on the loan to protect both the borrower and the lender.  The borrower is protected by limits in payment increases.  By lowering payment increases, there is less likelihood of default, which protects the lender.

Amortizing ARMs
Standard ARM programs come in a variety of  terms.  Standard ARMs are amortizing ARMs, meaning that the payments and the rate adjust at the same intervals and will pay the loan off over it’s initial term (i.e., 30 years) and will not have negative amortization.

Hybrid ARMs
There are mortgages that combine aspects of a fixed and an adjustable rate mortgage combined in the same loan - starting out fixed for a period of time (2-, 3-, 5-, 7- or 10-years), then converts to an adjustable rate loan.  When the loan begins to adjust, typically the adjustment periods are either each six months or each twelve months after the initial fixed period.  These loans have periodic interest rate caps when the loan begins to adjust.  When discussing the caps on these loans, there are three caps discussed.  The first cap is the rate cap on the first adjustment (when the loan goes from fixed to adjustable).  The second cap is the rate cap covering the ensuing adjustments (each six  or twelve months). The final cap is the lifetime interest rate cap.  For example, a 5/1 ARM might have 5/2/5 caps.  This indicates that after the initial fixed rate period of five years, the loan will adjust every twelve months.  After the fixed period, the interest rate can go up no more than 5.00%; every twelve months thereafter, the rate increase is limited to 2.00%; in no case can the interest rate ever exceed 5.00% over the initial interest rate on the loan.

Hybrid Interest Only ARMs
These loans are the same as the hybrid loans with the exception that they have an initial period where the minimum payments are interest-only payments.  This keeps the initial loan payments low and affordable.  The interest-only period usually runs with the fixed period, however, many lenders are now extending the interest-only period beyond the fixed period to ease a borrower into the transition from fixed to ARM.

Option ARMs
Option ARMs are the ultimate in “teaser” ARMs.  An Option ARM has two starting interest rates associated with it.  First is the rate which determines the starting minimum payment.  Second is the real interest rate, or the fully-indexed rate.  The interest rate on an Option ARM will adjust on a monthly basis.

The borrower’s minimum starting payment is based off of the interest rate which determines the minimum starting payment.  For example, the minimum starting payment may be based on an enticing interest rate such as 1.00%. 
The actual interest rate is the real fully indexed rate, for example 5.50%.  The borrower makes payments at the lower payment rate of 1.00%, however, the loan accrues interest at the fully-indexed rate of 5.50%, which may create a deficit in the interest payment, thereby causing negative amortization. 

The reason the loan is called an “Option” ARM is that the borrower will be given four payment options with each monthly billing:

  • Minimum payment – as defined and calculated above.
  • Interest-only payment – the payment required to pay the fully-indexed rate of interest accruing on the loan each month.
  • 30-year payment – the payment required to pay the loan off within the initial 30 (or 40) year term of the loan (this payment will change each month as this is a monthly adjustable rate loan.
  • 15-year payment – the payment required to pay the loan off within 15 years from the initial first payment date.

Option ARMs may be based on a 40-year amortization.

Home Equity Lines Of Credit (HELOCs)
A HELOC is a revolving line of credit and can be either a first or a second mortgage.   HELOCs are very useful financial tools.  They give you ready cash for large purchases, allowing you to go into purchase negotiations with the power of a cash transaction.  For example, if you are looking to purchase a car, you are not at the effect of the monthly payment tactics of the car dealership.  You can merely negotiate the best price.  In addition, the interest on a HELOC may be tax deductible (check with your tax advisor for details).

A HELOC is an adjustable rate loan, usually tied to the Prime Lending Rate.  Just like other ARMs, the HELOC has an index and a margin.  Typically there are no payment or periodic rate caps, so the interest rate charged on a HELOC is always the fully-indexed rate.  The typical lifetime interest rate cap on a HELOC is 18.00% (however, they may vary).
