    Common questions

    How often are these rates updated?

    Daily. We re-scrape the publicly posted rate pages from every credit union that lends in Arizona every morning.

    Do I need to join before applying?

    Yes — credit unions require membership before closing. Most let you open a share account and apply for a mortgage on the same day.

    Are these APRs or interest rates?

    We display both when the credit union publishes them. See our APR vs. interest rate vs. points guide.

    Why aren't the big banks listed?

    Most large banks don't publish mortgage rates online — they quote per applicant. Credit unions almost always post theirs publicly, which is why they dominate our comparison.
