Source transparency

Mortgage rate data sources

Every number keeps its source and observation date. The site checks for changes within a 15-minute cache window, but each publisher follows its own schedule. “Latest” means latest published by the source, not a live bank quote.

Locked-rate averages

Optimal Blue mortgage lock records, published through FRED

These numbers come from loans that have already been locked. They are closer to market activity than an advertised bank rate, but they are not a personal quote.

Official weekly averages

Freddie Mac Primary Mortgage Market Survey

Published once a week. It is slower than daily lock data, but useful for reading the national trend.

Market backdrop

10-year U.S. Treasury yield from FRED

This is not a mortgage rate, but it is one of the cleanest public signals for the rate environment.

Bank quote timing

Daily lender rate sheets

Most lenders publish a first rate sheet in the morning. If the bond market moves sharply, some lenders may reprice around midday or in the afternoon.

Publication schedule

The source date, not the page-check time, tells you how current a number is.

Locked-rate averages

30-year fixed, 15-year fixed, jumbo, FHA, and VA

Source: ICE / Optimal Blue, published through FRED
Typical timing: Usually updates on the next business-day morning Eastern Time; exact timing follows the source
Important detail: If the number has not changed in the morning, the source likely has not published yet. Weekends and U.S. bank holidays usually have no new observations. Blank dates are skipped and never treated as 0% rates.

Same-day bank quotes

Rates shown by banks, mortgage lenders, and loan officers

Source: Each lender's own rate sheet
Typical timing: Most lenders publish in the morning; some reprice around midday or afternoon if markets move
Important detail: These quotes are not one shared public dataset. Credit score, down payment, loan amount, points, property type, and lock period can all change the final quote.

Official weekly averages

Freddie Mac 30-year and 15-year fixed mortgage averages

Source: Freddie Mac PMMS, published through FRED
Typical timing: Every Thursday at 12:00 PM Eastern Time; if Thursday is a holiday, usually Wednesday
Important detail: This is a weekly average, not a daily update. It covers mortgage application data from the prior Thursday through Wednesday.

10-year Treasury

Rate environment signal

Source: Federal Reserve H.15, published through FRED
Typical timing: Monday to Friday at 4:15 PM Eastern Time
Important detail: No release on Federal Reserve holidays or market closure days. It is a market signal, not a mortgage rate.

Public data

Source links point to FRED, Freddie Mac, ICE, or the Federal Reserve.

Dated values

Old observations are never labeled as a new same-day quote.
