Automated Redfin Price Drop Tracking
Every morning, WebRun signs in to Redfin, walks your saved searches and favourites for listings that are new, have changed price, or have moved to pending or sold, updates a page per home in Notion with the change and any open house time, and appends the day's numbers to a price history sheet in Google Sheets.
How do I track price drops on the houses I am watching?
WebRun checks your Redfin saved searches and favourites every morning for new listings, price changes, and moves to pending or sold. It updates a Notion page per home with the change and any open house time, then logs the asking price and price per square foot to a Google Sheets history so drops are obvious.
- Price drops reach you the morning they post
- Every home on the shortlist has a full price history, not just today's number
- Open houses land on the page before the weekend fills up

Questions, answered
Will it contact an agent or book a tour?
No. WebRun reads Redfin only and writes to your own Notion and Google Sheets. It never messages an agent, requests a tour, submits an offer, or fills in a contact form on a listing.
What changes does it actually watch for?
New listings inside your saved searches, price changes on homes you favourite, moves to pending, contingent, or sold, and open house times added for the coming weekend.
Will it overwrite my own notes?
No. WebRun updates only the price, status, and open house fields on a Notion page. Your notes, ratings, and comments are left exactly as you wrote them.
