Apartments.com Bulk Availability Checker

WHAT IT DOES

Apartments.com Bulk Availability Checker solves a common rental search challenge: monitoring availability across multiple apartment listings is tedious when done manually. While Apartments.com shows individual listing availability, there is no native way to see all your saved listings with their availability status in one view. This tool reads your current Apartments.com search results or saved listings page, detects all visible rental listings, and displays them in a scrollable checklist with property names/addresses, prices, bed/bath counts, square footage, and availability status. You can check all listings at once to refresh their current availability status. The tool tracks availability changes by storing previous status and displays change indicators: green for available, red for unavailable, yellow for newly available. You can filter by availability status, view availability history, and export the complete dataset as CSV or JSON.

WHERE IT RUNS

This extension panel runs directly inside your browser as an overlay on any Apartments.com page displaying listings. It works on search results pages, saved listings, and property grid views. The tool extracts listing data from the page's DOM and uses local storage to track availability history. It requires no additional API keys or permissions beyond the BotGentz extension.

HOW TO USE

After installing the BotGentz extension and activating Apartments.com Bulk Availability Checker, navigate to any Apartments.com search results page or saved listings page. Click the extension icon in your browser toolbar to open the panel. The tool automatically detects all property listings displayed on the current page. Each listing appears with its name, price, beds/baths, and availability status. Click "Check Availability" to update all listings with their current availability status. The tool extracts the availability from the page and compares it with any previously stored status, showing the change direction. Use the filter dropdown to view only available, unavailable, newly available, or no longer available listings. The results section shows each listing with a status indicator and the change type. Click "Export Report" to copy the complete dataset to your clipboard in CSV or JSON format. Click "Clear History" to reset the availability tracking for all listings.

TECHNICAL OPERATION — DOM-Based Availability Extraction and Local Storage Tracking

This tool extracts listing data from the Apartments.com page by scanning for elements containing property information. It uses selectors like `[data-listing-id]`, `.property-card`, `.listing-card`, and `.placard` to identify listings, then extracts property names from name elements, prices from price elements, bed/bath counts from bed/bath elements, square footage from sqft elements, and availability from availability badge elements. The availability is determined by checking for keywords like "available" and "unavailable" in the badge text. Availability history is stored per listing using GM_setValue with keys like `availHistory_[listingId]`, storing an array of previous boolean statuses. When checking availability, the tool compares the current status with the most recent historical status to determine the change direction: newly available, still available, no longer available, or unchanged. The tool uses a 300ms delay between updates to ensure stable DOM access and prevent UI congestion. Results can be filtered by change status and exported as CSV with proper field quoting, or as structured JSON.

THE PANEL

The extension panel is fully draggable and remembers its position per site session. It snaps to the nearest edge of the browser viewport when dragged within 50 pixels of any side. You can collapse the panel to a compact title bar using the minimize button, preserving your selection state. The panel resizes vertically by dragging the bottom edge. Press the Escape key to close the panel instantly. The results update in real-time as you check availability or apply filters.

PLEASE NOTE

This tool requires the free BotGentz extension to function. The script extracts listing data from the page's DOM and stores availability history locally using GM_setValue. It does not transmit or log any listing data, availability information, or user activity. All operations are performed locally in your browser session. Availability history is stored per listing ID and persists across sessions. The tool only sees listings that are currently rendered in the page's DOM — scroll to load all listings before using the tool. Apartments.com may update its DOM structure over time, which could affect listing detection; we monitor and release compatibility updates as needed. Availability status is based on the information displayed on the page at the time of checking. Export formats include CSV and JSON for maximum compatibility with analysis tools.
