County Tax Sale Auction Monitor — Nationwide Calendar

Every county tax sale auction in one structured feed — and know the moment a new one is announced.

County tax-defaulted and tax-foreclosed property auctions are where real estate investors find deeply discounted deals — but the schedules live scattered across county sites and auction platforms, and the investors who hear about a sale first get the research head start. This actor turns the nationwide auction calendar into clean structured data: county, state, sale type, dates, status, and a direct auction link per record — currently covering the Bid4Assets platform (county sales across CA, WA, PA, NV, MN and more).

What it does

• 📅 Aggregates scheduled and announced county auctions into one dataset
• 🏷️ Classifies sale types: tax-defaulted, tax-foreclosed, judicial, repository, tax-title, surplus, sheriff
• 🔎 Filters by state, county, sale type, and upcoming-only
• 🚨 New-auction detection: flags every auction announced since your previous run — schedule daily and get an early-alert feed via Apify's Slack/email/webhook integrations
• 🤖 API, schedules, and MCP ready — AI agents can ask "what tax sales are coming up in California?" against live data

Who uses this

• Real estate investors & wholesalers tracking tax deed and foreclosure auctions across markets
• Land investors watching rural county sales that never hit mainstream listing sites
• Fund & research teams analyzing distressed inventory flow by state and season
• AI agents doing autonomous deal-flow monitoring

The early-alert workflow

1. Schedule daily with detectNew: true (add onlyNew: true for a pure alert feed)
2. Wire an Apify integration (Slack, email, webhook) to the run
3. You now hear about every newly announced county sale the morning it appears — while other investors are still checking pages by hand

Roadmap

Property-level lists per auction (parcels, minimum bids, assessed values) and additional platforms (Florida tax deed calendars, GovEase) are next — open an issue to vote on what lands first.

FAQ

Where does the data come from? Public county auction calendars published on auction platforms, starting with Bid4Assets (100+ counties historically).

How current is it? Every run fetches the live calendar; nothing cached between runs.

Why is an auction's status "announced" vs "scheduled"? Scheduled auctions have a live auction page; announced ones have a date but no page yet — those are the earliest signals.
