Discounts

Some lenders offer initial ARM rates that are lower than the sum of the index and the margin. Such rates, called discounted rates, are often combined with large initial loan fees ("points") and with much higher interest rates after the discount expires.

Very large discounts are often arranged by the seller. The seller pays an amount to the lender so the lender can give you a lower rate and lower payments early in the mortgage term. This arrangement is referred to as a "seller buydown." The seller may increase the sales price of the home to cover the cost of the buydown.

A lender may use a low initial rate to decide whether to approve your loan, based on your ability to afford it. You should be careful to consider whether you will be able to afford payments in later years when the discount expires and the rate is adjusted.

Here is how a discount might work. Let's assume the one-year ARM rate (index rate plus margin) is at 10%. But your lender is offering an 8% rate for the first year. With the 8% rate, your first year monthly payment would be $476.95.

But don't forget that with a discounted ARM, your low initial payment will probably not remain low for long, and that any savings during the discount period may be made up during the life of the mortgage or be included in the price of the house. In fact, if you buy a home using this kind of loan, you run the risk of ...

Payment Shock

Payment shock may occur if your mortgage payment rises very sharply at the first adjustment. Let's see what happens in the second year with your discounted 8% ARM.

ARM Interest Rate Monthly Payment
First year (w/discount) 8% $476.95
2nd year @ 10 % $568.82

As the example shows, even if the index rate stays the same, your monthly payment would go up from $476.95 to $568.82 in the second year. Suppose that the index rate increases 2% in one year and the ARM rate rises to a level of 12%.

ARM Interest Rate Monthly Payment
First year (w/discount) 8% $476.95
2nd year @ 12% $665.43

That's an increase of almost $200 in your monthly payment. You can see what might happen if you choose an ARM because of a low initial rate. You can protect yourself from large increases by looking for a mortgage with features, described next, which may reduce this risk.
