Immowelt Search Scraper

An Apify actor that automates data extraction from Immowelt.de, a major German real estate portal. It turns search results for rental and purchase properties into structured datasets.

Overview

The scraper collects detailed property listings from Immowelt.de based on your search criteria. It handles apartments, houses, commercial properties, and land plots. You provide a search URL, and it returns structured data including specifications, location, pricing, and agent information. This is useful for building market databases, tracking trends, or feeding data into analysis tools.

Key Features

• Comprehensive Data Extraction: Captures the full dataset displayed for each listing, not just surface details.
• Handles All Property Types: Works with apartments, houses, commercial real estate, and land.
• Processes Rentals & Purchases: Covers the full spectrum of German real estate transactions.
• Structured Output: Organizes data into formats (JSON, CSV, etc.) ready for analysis or database integration.
• Proxy Support: Built-in configuration for reliable scraping using residential proxies.

How to Use

1. Configure Your Search: Go to Immowelt.de and use their search interface. Apply filters for location, property type (e.g., House, Apartment), transaction type (Buy or Rent), and any other criteria.
2. Copy the URL: Once the results load, copy the full URL from your browser's address bar. This URL encodes all your search parameters.
3. Run the Actor: Input the URL into the actor, configure any run settings (like item limits), and start the scrape.
