An originator explains an ARM by quoting the current index alone and never mentions the margin. A reviewer listening in stops the call. What has been left out of the arithmetic?

Correct Answer

D) Apply the index, margin, and cap rules to the ARM adjustment

Why this is correct: Adjustable-Rate Mortgages (ARMs) have specific features defined by contract and regulation. The future interest rate is calculated by adding a fixed "margin" to a variable "index" rate. "Caps" limit how much the rate or payment can change at each adjustment period and over the loan's life. The correct action, "Apply the index, margin, and cap rules to the ARM adjustment," is the precise, technical step required to ensure the adjustment is calculated correctly and disclosed properly to the borrower. Why the other choices are wrong: "Apply a different loan-program rule without checking the file facts" is wrong because ARM adjustments must follow the specific terms disclosed in the loan documents, not arbitrary rules. "Ignore product, occupancy, LTV, or eligibility limits because the borrower prefers the loan" is wrong because ARM features are contractual terms, not preferences. "Use the same treatment for all mortgage products without comparing program requirements" is wrong because fixed-rate loans do not have adjustment mechanisms; applying the same treatment would be incorrect. Exam tip: For ARM questions, remember the core components: Index + Margin = New Rate, subject to Periodic and Lifetime Caps.

Answer Options
A
Apply a different loan-program rule without checking the file facts.
B
Ignore product, occupancy, LTV, or eligibility limits because the borrower prefers the loan.
C
Use the same treatment for all mortgage products without comparing program requirements.
D
Apply the index, margin, and cap rules to the ARM adjustment

Why This Is the Correct Answer

The correct response is "Apply the index, margin, and cap rules to the ARM adjustment" because ARM products use an index, margin, adjustment periods, caps, and payment-change disclosures.

Why the Other Options Are Wrong

Option A: Apply a different loan-program rule without checking the file facts.

Apply a different loan-program rule without checking the file facts. is not correct because it does not apply the rule tested by this file scenario.

Option B: Ignore product, occupancy, LTV, or eligibility limits because the borrower prefers the loan.

Ignore product, occupancy, LTV, or eligibility limits because the borrower prefers the loan. is not correct because it does not apply the rule tested by this file scenario.

Option C: Use the same treatment for all mortgage products without comparing program requirements.

Use the same treatment for all mortgage products without comparing program requirements. is not correct because it does not apply the rule tested by this file scenario.

Memory Technique

ARM features and caps: identify the rule being tested, then choose the action that documents or applies that rule before the file moves forward.

Exam Tip

Match the file facts to ARM features and caps; do not choose an exception or shortcut that skips the required rule.

Common Mistakes to Avoid

  • -Choosing an internal exception instead of the governing rule
  • -Treating preliminary or informal facts as a substitute for required documentation
  • -Answering from a familiar but unrelated mortgage topic
