Immowelt Scraper — German Real Estate Listings with Broker Data

What does Immowelt Scraper do?

Immowelt Scraper extracts structured property data from immowelt.de — including pricing data, full descriptions, and location data. It supports keyword search, location filters, and controllable result limits, so you can run the same query consistently over time. The actor also offers detail enrichment (full descriptions and company profiles) where the source provides them.

Key features

• ♻️ Incremental mode — daily runs emit only listings that are new or whose price/condition changed since last run. Perfect for inventory-diff dashboards and competitive pricing alerts. Saves 80–95% on recurring monitoring.
• 🔔 Notifications — telegram / Slack / Discord / WhatsApp / webhook alerts on each run. Combine with incremental to ping only when prices or inventory actually move.
• 🔗 Paste-mode — paste any immowelt.de URL — single-listing pages, search-results, or category SEO URLs. Build the filter you want in the browser, copy, paste; the actor parses every query param.
• 📋 Detail enrichment — two-stage scraping — list first, then enrich each listing with the full detail-page payload. One input toggle controls the depth.
• 📧 Email + phone extraction — best-effort regex extraction of contact emails and phone numbers from descriptions — emitted as extractedEmails[] and extractedPhones[] on every record.
• 🎯 Batch searches — run multiple search variants in one job — shared dedup, single dataset for compare/diff downstream.
• 📦 Compact mode — light payload with core fields only — comparable rows across listings without HTML or metadata overhead. Perfect for pricing dashboards.
• ✂️ Description truncation — cap description length with descriptionMaxLength to control LLM prompt cost and dataset size — set 0 for full descriptions, or any char-limit to trim.
• 📌 Change classification — each record carries a changeType of NEW / UPDATED / UNCHANGED / REAPPEARED / EXPIRED. Default emits NEW + UPDATED + REAPPEARED; opt into the others with emitUnchanged / emitExpired. Repost detection flags previously-expired listings that come back.
• 📤 Export anywhere — Download the dataset as JSON, CSV, or Excel from the Apify Console, or stream live via the Apify API and integrations (Make, Zapier, Google Sheets, n8n, …).

What data can you extract from immowelt.de?

Each result includes Core listing fields (jobId, jobKey, title, location, street, district, postalCode, and salaryText, and more), detail fields when enrichment is enabled (description, descriptionHtml, descriptionLength, and detailFetched), and company metadata (company and companyUrl). In standard mode, all fields are always present — unavailable data points are returned as null, never omitted. In compact mode, only core fields are returned.

Enable detail enrichment in the input to get richer fields such as full descriptions and company profiles where the source provides them.

Input

The main inputs are a search keyword, an optional location filter, and a result limit. Additional filters and options are available in the input schema.

Key parameters:

• query — Property search keywords. Use JSON array for multi-query. Leave empty when using startUrls only.
• country — Which immowelt.de market to search. (default: "DE")
• city — City or region to search in (e.g. "Berlin", "München"). Use JSON array for multiple cities. Recommended over 'query' for location-based searches.
• distributionType — Filter by buy, rent, or both. (default: "buy")
• estateType — Filter by property type. (default: "apartment_and_house")
• radiusKm — Extend search beyond the city boundary by this many kilometres. Requires 'city' input. 0 = city boundary only. (default: 0)
• location — Legacy field. Use 'city' instead.
• startUrls — Direct Immowelt search URLs or expose URLs.
• maxResults — Maximum total property listings to return after dedupe and post-fetch filters (0 = unlimited). Apify charges per emitted record, so this is your primary cost control. When both maxResults and maxPages are set, the run stops at whichever cap is reached first. Dynamic memory profile: up to 25 results uses 1024 MB, 26+ results uses 2048 MB. (default: 25)
• maxPages — Maximum search-result pages to scrape per search source. Defensive safety bound — maxResults is the primary record cap. (default: 5)
• includeDetails — Fetch each expose page for full description, price data, and provider info. (default: true)
• transport — Choose the standard fetch mode or browser mode for tougher pages. (default: "browser")
• ...and 23 more parameters

Input examples

Basic search — Keyword-driven search with a result cap.

→ Full payload per result — all standard fields populated where the source provides them.

{
  "query": "altbau balkon",
  "maxResults": 50
}

Incremental tracking — Only emit properties that changed since the previous run with this stateKey.

→ First run builds the baseline state. Subsequent runs emit only records that are new or whose tracked content changed. Set emitUnchanged: true to include unchanged records as well.

{
  "query": "altbau balkon",
  "maxResults": 200,
  "incrementalMode": true,
  "stateKey": "altbau-balkon-tracker"
}

Compact output for AI agents — Return only core fields for AI-agent and MCP workflows.

→ Small payload with the most important fields — ideal for piping into LLMs without token overhead.

{
  "query": "altbau balkon",
  "maxResults": 50,
  "compact": true
}

Output

Each run produces a dataset of structured property records. Results can be downloaded as JSON, CSV, or Excel from the Dataset tab in Apify Console.

Incremental fields

When incremental: true, each record also carries:

• changeType — one of NEW, UPDATED, UNCHANGED, REAPPEARED, EXPIRED. Default output covers NEW / UPDATED / REAPPEARED; set emitUnchanged: true or emitExpired: true to opt into the others.
• firstSeenAt, lastSeenAt — ISO-8601 timestamps tracking the listing across runs.
• isRepost, repostOfId, repostDetectedAt — populated when a new listing matches the tracked content of a previously expired one. Set skipReposts: true to drop detected reposts from the output.

How much does it cost to scrape immowelt.de?

Immowelt Scraper uses pay-per-event pricing. You pay a small fee when the run starts and then for each result that is actually produced.

• Run start: $0.005 per run
• Per result: $0.0009 per property record

Example costs:

• 10 results: $0.01
• 100 results: $0.1
• 500 results: $0.46

Example: recurring monitoring savings

These examples compare full re-scrapes with incremental runs at different churn rates. Churn is the share of listings that are new or whose tracked content changed since the previous run. Actual churn depends on your query breadth, source activity, and polling frequency — the scenarios below are examples, not predictions.

Example setup: 100 results per run, daily polling (30 runs/month). Event-pricing examples scale linearly with result count.

Churn rate	Full re-scrape run cost	Incremental run cost	Savings vs full re-scrape	Monthly cost after baseline
5% — stable niche query	$0.10	$0.0095	$0.09 (90%)	$0.28
15% — moderate broad query	$0.10	$0.02	$0.08 (81%)	$0.55
30% — high-volume aggregator	$0.10	$0.03	$0.06 (66%)	$0.96

Full re-scrape monthly cost at daily polling: $2.85. First month with incremental costs $0.37 / $0.63 / $1.02 for the 5% / 15% / 30% scenarios because the first run builds baseline state at full cost before incremental savings apply.

Platform usage (compute and proxies) is billed separately by Apify based on actual consumption. Incremental runs consume less on result processing, though fixed per-run overhead stays the same.
