Adjustable-Rate Mortgages

An adjustable-rate mortgage holds the rate steady for an initial period, then adjusts on a set schedule based on an index plus a margin, within caps written into the note. The structure can suit a shorter expected ownership horizon, but the adjustment mechanics deserve a careful walkthrough before you commit.

• Buyers who expect to sell or refinance before or near the end of the fixed period
• Borrowers comfortable with future payment variability in exchange for a lower start
• Buyers in higher price bands where a small rate difference moves the payment noticeably

• The introductory rate is often lower than a comparable fixed rate
• Adjustment caps limit how far the rate can move at each change and over the life of the loan
• Can be a reasonable fit when the ownership horizon is genuinely short

• The payment can rise once the fixed period ends, potentially significantly
• Plans change — the loan should still be workable if you stay longer than expected
• Index, margin, caps and adjustment frequency all vary by program and must be read in the note

These are the factors an underwriter typically reviews. They are not a checklist of requirements, and meeting them does not guarantee eligibility or approval.

• Qualifying is generally reviewed against program-specific rules, which may not use the introductory rate
• Credit, income, asset and debt-to-income review
• An acceptable property and appraisal

• Monthly payment estimator
• Side-by-side loan comparison
