Read in this order

  1. The core concepts behind mortgage pricing in one place: what a rate is, what moves it and how to get a real quote.

    • A mortgage rate is the price of borrowing.
    • Every offer combines an interest rate with a cost.
  2. A structured set of questions to decide between a fixed-rate loan and an ARM.

    • If you expect to keep the loan beyond the ARM’s fixed period, a fixed rate removes payment uncertainty.
    • Calculate the maximum payment the ARM caps allow.
  3. The basic differences between fixed-rate and adjustable-rate mortgages, and how to decide which fits.

    • A fixed-rate mortgage keeps the same interest rate for the life of the loan, so principal and interest stay the same.
    • An adjustable-rate mortgage has an initial fixed period, then adjusts periodically based on an index plus a margin.
  4. Rate Words That Confuse PeopleUnder 2 min min read

    Plain definitions of note rate, annual percentage rate, par pricing, points and other terms you will see in quotes.

    • The interest rate written into your promissory note, used to calculate monthly interest.
    • A yearly measure that includes the note rate plus certain fees, spread over the full term.
  5. A plain-language checklist for first-time buyers who want to compare loan offers with confidence.

    • Before calling lenders, know a few terms: the interest rate, discount points, lender credits, the Loan Estimate, a rate lock and the Closing Disclosure.
    • Prequalification gives you a rough idea of what lenders may offer.
