Use the table below to choose the narrower mortgage or real-estate finance branch before applying a term to a loan file, closing record, servicing review, investor report, appraisal, or valuation model. Move into the term page when the document, calculation, party role, lien position, or property cash flow matters.

What This Branch Covers

What to Check

• Note rate, APR, index, margin, reset period, cap, floor, teaser rate, lock agreement, and rate sheet.
• Fixed, adjustable, hybrid, buydown, discount, offset, or renegotiated-rate structure.
• Points, fees, lock expiration, float-down terms, conversion options, and payment adjustment schedule.
• Effect on payment, affordability, refinancing, prepayment, default risk, and investor yield.
• Whether quoted rates include points, fees, program limits, and borrower assumptions.

Common Mistakes

• Comparing rates without APR, points, fees, lock terms, and loan assumptions.
• Ignoring ARM caps, margins, indexes, reset dates, and payment shock.
• Treating a rate quote as a locked rate.
• Assuming a buydown permanently lowers all loan economics.
