Immowelt Scraper — German Rentals & Sales, Price Changes

Give it German places — a city for rent or for sale, apartments or houses, or an Immowelt search address — and get one clean row per listing: price (cold and warm rent, or purchase price), rooms, living space, price per m², city, district, postal code, features, agency, photo and listing dates. $1.50 per 1,000 listings, up to 1,000 listings per search, no login, no API key.

Run it again — or put it on a daily schedule — and every row also tells you what changed since the last run: whether the listing is new, its previous price and the price change in euros and percent. Immowelt's pages show only today's price; this keeps yesterday's, so a schedule becomes a price-cut and new-listing alert. Each search also gets one free summary row: results found, listings read, new listings, price drops, the median price and median price per m² of what was read, and Immowelt's own average price per m² for the city.

What you get

Field	What it is
type, search	listing, summary or error; the search entry the row belongs to
id, url, title	Immowelt's listing ID, the link, and the ad's headline (a phone number or e-mail address typed into it is cut out, with the words next to it; when a private landlord wrote no headline, Immowelt's generic title such as Wohnung zur Miete is used)
deal, propertyType	rent, buy, auction or forced-auction; apartment or house
price, priceType, priceText, currency	the price as a number in euros. priceType is rent-cold (Kaltmiete, per month), rent-warm (only a Warmmiete is given) or purchase. price is null when the ad says "price on request" (priceText keeps Immowelt's wording)
warmRent	rentals: the warm rent (Warmmiete) when the ad gives both
pricePerSqm	price divided by the living area (or by the total area when the ad only gives that): euros per m² per month for rentals, euros per m² for purchases
rooms, livingAreaSqm, totalAreaSqm, plotAreaSqm	rooms (half rooms such as 2.5 exist), living area, total area (some purchases, such as whole buildings, give only this), plot size of houses
floor, floorsInBuilding	floor (0 is the ground floor) and storeys, when the ad says
availableFrom, availableImmediately	the move-in date, or true for "frei ab sofort"
energyClass, condition, isNewBuild	energy class (A+ to H), Immowelt's condition label (first-time-use, mint-condition, fully-renovated, well-kept, need-of-renovation, projected…) and whether the listing belongs to a new-build project
city, district, postalCode	where it is. Street and house number are not returned
features	tags read from the ad's text and photo captions and from the photo types Immowelt assigns: balcony, terrace, garden, fitted-kitchen, lift, cellar, parking, floor-heating, barrier-free, fireplace. A word after "ohne", "kein" or "nicht" does not count. An empty list means the text does not mention them, not that the home has none
sellerType, agency, agencyUrl	agency or private. For agencies (businesses): the company name and its Immowelt profile page. For private landlords both are null and nothing identifies the landlord
imageUrl, imageCount, hasFloorPlan	the first photo, how many photos there are, and whether a floor plan is attached
listedAt, updatedAt, newOnSite	when the listing was created and last updated on Immowelt, and Immowelt's own "new" badge (on 2026-10-09, 67 of the 69 badged listings in a check of 195 across four cities had been updated within the previous 7 days)
isNew, previousPrice, priceChange, priceChangePct, previousSeenAt	the change since your previous run of the same search (null on the first run). priceChange is negative when the price dropped
firstSeenAt, daysSinceFirstSeen, firstSeenPrice, priceChangeSinceFirstSeen	the first run of this Actor that saw the listing, the days since, the price then, and the total change since
observedAt	when the row was read (ISO time)

The summary row (type: "summary", free) has searchUrl (the Immowelt page your search led to), place, deal, propertyType, totalResults (how many listings Immowelt says the search has), listingsRead, listingsOutput, pagesRead, complete (true when every listing of the search was read), newSinceLastRun, priceDrops, priceIncreases, medianPrice, medianPricePerSqm, marketCity, marketAsOf, marketPricePerSqm, marketChange1YearPct, firstRun and a note that says in words what the numbers cover. The market… fields are Immowelt's own average price per m² for the city and the property type of your search, with its change over one year.

Input

{
  "searches": [
    { "city": "Berlin", "type": "apartment", "deal": "rent" },
    { "city": "München", "type": "house", "deal": "buy" },
    "https://www.immowelt.de/suche/mieten/wohnung/sachsen/leipzig-04103/ad08de10168"
  ],
  "maxListingsPerSearch": 100,
  "onlyChanges": false
}

A search is either an object with city, type (apartment or house, default apartment) and deal (rent or buy, default rent), or an Immowelt address that starts with immowelt.de/suche/. Up to 50 searches per run. Write the city as you like (München, Frankfurt am Main); the Actor turns it into Immowelt's spelling. To go narrower than a city, use the address of a district page or a room-count page that Immowelt links from the city's page (for example immowelt.de/suche/mieten/wohnung/zimmer-2/berlin/berlin-10115/ad08de8634); those addresses work as searches too.

With Only new listings and price changes (onlyChanges) the Actor outputs, from the second run of a search on, just the listings that are new or changed in price, and you pay only for those. The first run of a search still outputs everything.

What is remembered is kept per search (its Immowelt page, not the limit) in a named key-value store in your Apify account, so the second run of the same search already shows changes. A listing that has not been seen for 45 days is forgotten. Schedule it (Apify → Schedules) for a daily history.

Pricing

$1.50 per 1,000 listings, plus $0.01 per run. Error rows (a place Immowelt does not know, a page that could not be read) and the summary rows are free. With Only new listings and price changes on, listings that did not change are not returned and not charged. The $0.01 run-start fee is the one charge every run pays, even one that returns nothing.

Notes

• Public data only: what anyone sees on Immowelt's public search pages without signing in. The Actor reads only pages under immowelt.de/suche/, which Immowelt's robots.txt does not disallow (checked 2026-10-09); it does not use the classified-search filter pages that robots.txt disallows. No field carries a landlord's name, phone number or e-mail address, street and house number are not returned as fields, and the ad's long text is not returned at all. For agencies only the company name is given. The one free-text field is title, the seller's own headline: phone numbers and e-mail addresses (with the words next to them) are cut out of it, but a seller can still type a street name into it. In my checks on 2026-10-09, 2 of 1,000 Berlin rental headlines did, and none of the 92 headlines from private landlords in that sample contained a person's name.
• What one search gives. Immowelt's public search page shows only the first 30 listings of a search (40 for house searches in some places, such as Berlin on 2026-10-09), always in Immowelt's own order, which is not newest first. There is no second page, no sort order and no price or area filter on the pages that can be read; those exist only on Immowelt's filter pages, which block automated reading. Because of this, filters written into an address (?priceMax=…, ?page=…) are ignored by Immowelt, and the summary note lists them so you are not misled. Links that start with immowelt.de/classified-search are refused with a free error row.
• How it reaches more than 30. The page itself links to narrower pages, by room count and by district (30 each). The Actor follows them, room counts first, then districts within a room count, and removes duplicates by listing ID, until it has your limit or has read everything. When I measured it on 2026-10-09, a Berlin rental search needed about 5 pages for 100 listings, 18 for 400 and 46 for 1,000 (roughly two minutes for the last). It reads at most 80 pages per search. Searches that already have a room count read districts only. If a narrower page fails, the listings read so far are kept and a free error row says where it stopped.
• Medians come from what was read. Because of Immowelt's order, the listings read are not a random sample: the first 100 Berlin rentals I read on 2026-10-09 had a median of about 23 euros per m², while Immowelt's own city figure (marketPricePerSqm, as of 2026-10-01) was 14.63. Use the market… fields for the city average and the medians for the listings you got.
• Reliable new-listing alerts. A listing counts as new when no earlier run of this search read it. If the search has more listings than your limit, a listing can show up only because the reading window moved. Check complete in the summary row (true when everything was read) and narrow the search (a district, a room count) until it has fewer listings than your limit; listedAt tells you when the ad was really created.
• Place names. The city is turned into Immowelt's address by Immowelt itself (muenchen, frankfurt-am-main). A name that exists in many places (for example Neustadt) or that Immowelt spells differently is answered with a free error row; paste an Immowelt address instead.
• Some fields are empty by design: warmRent for purchases and for rentals that give only one rent; plotAreaSqm for apartments; totalAreaSqm unless the ad gives a total area instead of a living area; floor and floorsInBuilding for most houses and when the ad does not say; availableFrom and availableImmediately when the ad gives no move-in date; energyClass and condition when the ad gives none; agency and agencyUrl for private landlords (and agencyUrl for agencies without a profile page); pricePerSqm when there is no price or no area; postalCode for a few listings in which Immowelt hides it. The change fields (previousPrice, priceChange, priceChangePct, previousSeenAt, priceChangeSinceFirstSeen) are null on the first run of a search and for a listing first seen now; isNew is null on the first run only. A listing whose rent type changed (cold to warm) between runs is not compared.
• Some sellers type a placeholder price instead of a real one (for example, among 1,000 Berlin rentals on 2026-10-09: a rent of 12.23 euros for 34 m² and one of 59,152 euros for 41 m²). A median is not thrown off by a few of them, but filter them out of any average you compute yourself.
• If Immowelt rate-limits or has a short outage, the Actor waits and retries twice. If its bot protection blocks a page, that search ends with a free error row. A run that could read nothing at all fails.
• Germany only: Immowelt's pages for other countries are not read.
