Mortgage Rate Lookup

Multi-lender mortgage rate comparison tool. Scrapes real rates from 13 lenders + 2 national benchmarks (Freddie Mac PMMS, Mortgage News Daily), ranks them lowest to highest, and tracks day-over-day changes.

What It Does

  • Scrapes 13 lenders via patchright stealth browser (headless Chromium)
  • Pulls Freddie Mac PMMS via direct CSV API (no browser)
  • Pulls Mortgage News Daily via urllib (no browser)
  • Compares 30yr fixed, 15yr fixed, ARM, FHA, VA products
  • Ranks by lowest rate with APR
  • Tracks 90-day rolling history for day-over-day change detection
  • Outputs clean text report to stdout (pipe to Discord/Slack/email)

    • Setup

    pip install patchright
python3 -m patchright install chromium

    Create config.json in the skill directory: 

    {
  "zip_code": "YOUR_ZIP"
}

    Usage

    # Headless, automated lenders only
python3 mortgage_rate_report.py
    Override ZIP code
    
python3 mortgage_rate_report.py --zip 90210
    Visible browser for debugging
    
python3 mortgage_rate_report.py --headed

    Architecture

    Two-tier fetching

    1. Tier 1 — Direct APIs (no browser): Freddie Mac CSV + MND HTML via urllib. Fastest. 2. Tier 2 — Stealth browser: 13 lenders via patchright. Parallel batches of 4, sequential retry on failure.

    Retry logic

  • Batches of 4 lenders in parallel
  • Failed lenders retry sequentially (up to 3 attempts)
  • Wait schedule: 8s → 12s → 15s

    • Rate extraction

    Regex patterns find rate/APR pairs for each product type. Rates validated between 3.0% and 12.0%.

    Output Example

    === Mortgage Rate Report (2026-04-06) ===
ZIP: 12540
    30-Year Fixed (lowest → highest):
  Freddie Mac PMMS:  6.65%
  Rocket Mortgage:   6.75% (APR 6.82%)  ▼ -0.125
  Wells Fargo:       6.875% (APR 6.94%)
  Chase:             6.99% (APR 7.05%)  ▲ +0.125
  ...
    15-Year Fixed (lowest → highest):
  ...
