Mortgage Rates, Locks, and Rate Sheets

Mortgage rates, rate locks, lock periods and extensions, float-down rights, lender rate sheets, and loan-level pricing adjustments.

Mortgage Rates, Locks, and Rate Sheets explains how mortgage interest rates become borrower offers, how lenders hold that pricing before closing, and how points, credits, lock periods, and loan characteristics affect the result.

Start with Mortgage Rate for payment and APR comparisons. Use Mortgage Rate Lock for the conditional pre-closing commitment, then move to the timing or pricing page that matches the question.

A complete comparison keeps the product, term, loan amount, lock period, points, credits, occupancy, property, and borrower assumptions consistent. The Loan Estimate and written lock confirmation are stronger transaction evidence than an advertisement or generic rate table.

What to Check

  • Note rate, APR, points, lender credits, origination charges, and total payment.
  • Product, term, loan amount, occupancy, purpose, property type, credit assumptions, and LTV.
  • Lock date, expiration date and time, required closing event, extension policy, and float-down terms.
  • Rate-sheet timestamp, price convention, adjustments, caps, waivers, and footnotes.
  • Whether transaction-specific documents reconcile with the original quote and lock.

Common Mistakes

  • Comparing rates from different dates, products, or lock periods.
  • Treating a quote or rate sheet as a confirmed lock or loan approval.
  • Ignoring points, lender credits, extension cost, or loan-level adjustments.
  • Presenting an internal pricing adjustment as necessarily being a separate borrower fee.
