Immonet.de Property Search Scraper: Extract German Real Estate Listings Data

Understanding Immonet.de and Its Value

Immonet.de is a major German real estate portal connecting buyers, renters, and sellers across German cities—from Berlin apartments to Munich houses and Hamburg commercial properties. The platform aggregates listings from agencies, developers, and private sellers, creating a comprehensive database of German real estate.

For investors analyzing German markets, agencies monitoring competition, or researchers studying housing trends, Immonet data provides crucial insights. Manual data collection requires endless scrolling and copying. This scraper automates extraction, transforming search results into structured datasets ready for analysis.

What This Scraper Extracts

The scraper processes Immonet search result pages—listings displayed after applying filters for location, price, property type, or features. It efficiently captures multiple properties from search pages, ideal for building comprehensive datasets across regions or categories.

Key Data Extracted:

Property Identification: Listing ID, reference number, and detail URL for tracking specific properties

Pricing Information: Sale/rent price, additional costs, heating costs, and deposit amounts

Location Data: City, district, postal code, street address, and coordinates for geographic analysis

Property Specifications: Living area, plot size, room count, bedroom count, bathroom count, and floor level

Property Features: Property type, condition, heating type, energy certificate, parking spaces, and amenities

Visual Assets: Image galleries, floor plans, and virtual tour links

Contact Information: Agent/owner details, company information, phone numbers, and viewing availability

Listing Details: Publication date, last update, availability status, and commission information

Additional Data: Property description, key features, construction year, and special attributes

Input Configuration

The scraper processes Immonet search result URLs with specific parameters.

Example Configuration:

{
  "proxy": {
    "useApifyProxy": true,
    "apifyProxyGroups": [
        "RESIDENTIAL"
    ],
    "apifyProxyCountry": "DE"
  },
  "max_items_per_url": 20,
  "ignore_url_failures": true,
  "urls": [
    "https://www.immonet.de/classified-search?distributionTypes=Buy,Buy_Auction,Compulsory_Auction&estateTypes=House,Apartment&locations=AD08DE8634&page=2&order=Default"
  ]
}

Example Screenshot:

Parameter Breakdown:

proxy: Default false. Enable useApifyProxy: true with residential proxies for large-scale scraping to avoid detection. Small occasional runs typically don't require proxies.

max_items_per_url: Controls properties extracted per URL. Set to 20 for standard pages. Immonet displays 20-30 listings per page. Increase for complete extraction.

ignore_url_failures: When true, continues processing if URLs fail. Essential for batch operations—one broken URL won't stop the entire job.

urls: Immonet search result page URLs. Include multiple URLs for different searches, locations, or pagination.

Understanding URL Parameters:

• distributionTypes: Transaction types (Buy, Buy_Auction, Compulsory_Auction, Rent)
• estateTypes: Property types (House, Apartment, Commercial, Land)
• locations: Geographic location code
• page: Pagination number for multiple pages
• order: Sort order (Default, Price_Asc, Price_Desc, Publication_Date)

Pro Tip: Perform manual searches on Immonet first, apply desired filters, then copy URLs. For comprehensive datasets, include multiple page numbers systematically.

Output Structure and Data Fields Decoded

The scraper returns structured data with each property listing as a comprehensive object. Understanding these fields helps you extract maximum value from the collected information.

Brand identifies the Immowelt platform brand, useful when aggregating data from multiple real estate portals. This field ensures you can track data provenance when building multi-source databases.

ID provides a unique identifier for each property listing. This field is critical for tracking specific properties over time, detecting when listings are updated or removed, and building relational databases that connect property data with other information sources.

Status indicates the listing's current state—whether it's active, reserved, sold, or rented. This field is invaluable for market velocity analysis, showing how quickly properties move off the market and identifying high-demand areas.

Metadata contains technical information about the listing including creation date, last update timestamp, and platform-specific identifiers. This data enables temporal analysis, helping you understand how long properties typically remain listed and when peak listing activity occurs.

Location provides comprehensive geographic information including full address, postal code, city, district, and often coordinates. German addresses follow specific formatting conventions, and this field captures them accurately. Location data enables geographic analysis, mapping property distributions, and calculating proximity to amenities or transport links.

Hard Facts contains the core property specifications: square meters, number of rooms, bathrooms, floor level, construction year, and condition. In the German market, these specifications follow standardized definitions—for example, room counts exclude bathrooms and kitchens. This structured data enables precise property comparisons and filtering.

Gallery provides URLs to all property images. Visual assets are crucial for property evaluation, and having direct image links enables automated image downloading, gallery creation, or computer vision analysis to assess property conditions.

Tracking includes analytics and monitoring information embedded in the listing. This metadata can reveal listing popularity, view counts, or engagement metrics that indicate market interest levels.

Provider contains information about the listing agent or property owner, including company name, contact details, and agent profile information. This data is essential for understanding who dominates specific market segments and for direct outreach to property sellers.

Card Provider specifically identifies the real estate agency or individual presenting the listing, which may differ from the property owner. In Germany's real estate market, understanding agent networks and their market presence provides competitive insights.

Main Description captures the full property description text as written by the listing agent. This rich text data contains information beyond structured fields—renovation details, neighborhood characteristics, nearby amenities, and selling points. Natural language processing on these descriptions can reveal market language trends and identify property features that correlate with faster sales.

Type specifies the property category within Immowelt's classification system (apartment, house, commercial, etc.), including subcategories that provide detailed property characterization relevant to German real estate conventions.

URL provides the direct link to the full property listing page. This enables verification, manual review of specific properties, or additional detailed scraping if needed.

Portal confirms the source platform (Immowelt.de), useful when aggregating data from multiple German real estate portals like ImmobilienScout24 or eBay Kleinanzeigen.

Raw Data contains the complete, unprocessed data object as received from Immowelt's servers. This field preserves all information even if the scraper doesn't explicitly parse certain fields, ensuring no data loss and enabling future re-processing if you identify additional valuable fields.

Tags includes classification labels, features, and characteristics that Immowelt uses to categorize properties—tags like "balcony," "garage," "elevator," or "energy-efficient." These tags enable feature-based filtering and analysis of which property characteristics are most common or valuable in different markets.

Display contains presentation metadata controlling how the listing appears on Immowelt, including premium placement indicators, featured listing status, or special highlighting. This information reveals which agents invest in promoted listings and can indicate property pricing strategies.

Step-by-Step Implementation

1. Define Target Market: Identify needed properties—locations, price ranges, types. Test searches on Immonet to verify filters return relevant results.

2. Collect Search URLs: Copy URLs from manual searches. Create multiple URLs for different cities, price brackets, or property types.

3. Configure Input: Set up JSON with URLs. Adjust max_items_per_url (20 standard, higher for thorough extraction). Enable ignore_url_failures for resilience.

4. Launch Scraper: Start via Apify console. Monitor progress. Typical processing: 3-5 pages complete in 2-4 minutes.

5. Validate Data: Preview results. Verify critical fields (prices, locations, specifications) are populated correctly.

6. Export and Analyze: Export as JSON, CSV, or Excel. Remove duplicates by listing ID. Filter by criteria (price, location, type).

7. Handle Pagination: For large datasets, include multiple page URLs: page=1, page=2, etc. Calculate pages based on search counts.

Error Prevention: Ensure URLs are search pages, not property details. Verify URLs load properly. Check filters produce expected results.

Strategic Applications

Market Price Analysis: Aggregate pricing across cities and property types. Calculate average EUR per square meter, identify trends, detect undervalued properties.

Competitive Intelligence: Agencies monitor competitor listings, pricing strategies, market positioning. Track dominant agencies by region.

Investment Research: Filter by location, price, condition to identify opportunities. Track new listings via publication dates.

Geographic Analysis: Use coordinates and location data to create heatmaps, analyze regional markets, identify emerging neighborhoods.

Property Valuation: Extract comparable properties (same area, similar specifications) for fair market value assessment.

Agency Performance: Aggregate by agent/company to analyze market share, average prices, property types handled.

Energy Efficiency Trends: Analyze energy certificates across regions and price ranges to understand sustainability impact on pricing.

Advanced Techniques

Time-Series Tracking: Scrape weekly/monthly with timestamps. Track price changes and listing durations by matching IDs.

Price-Per-SQM Analysis: Calculate value metrics across neighborhoods. Identify best value locations.

Condition-Price Correlation: Analyze how property condition affects pricing. Quantify renovation impact.

Feature Premium Analysis: Determine price premiums for specific amenities (balcony, elevator, parking).

Auction Monitoring: Filter distributionTypes=Buy_Auction,Compulsory_Auction to track distressed properties and investment opportunities.

Cross-Platform Validation: Compare Immonet listings with ImmobilienScout24 or Immowelt by matching addresses or reference numbers.

Best Practices

Scraping Frequency: German real estate updates regularly. Weekly scraping balances freshness with efficiency. Daily for fast-moving markets (Berlin, Munich).

Data Validation: Implement checks—prices positive, coordinates within Germany, required fields populated. Flag anomalies.

Privacy Compliance: Contact information subject to GDPR. Handle securely, use for legitimate purposes only.

Duplicate Management: Use listing ID to deduplicate. Properties may appear in overlapping searches.

Currency Consistency: All prices in EUR. Note scrape dates for economic context.

Quality Assurance: Validate extreme values. Check property types match expected categories.
