Disclosure: I built the Apify Actor used in this tutorial. This post was written with AI assistance.
Finding a flat to rent in Vienna rewards whoever sees a listing first, and the comparisons you actually want, like rent per square metre by district, are not on the listing page. This tutorial builds a daily feed of new ImmoScout24 Austria rentals with the ImmoScout24 Austria Scraper (highbrow_fame/immoscout24-at-properties) on Apify. You set the filters once, a Python script runs every morning, keeps only listings it has not shown you before, computes rent per m², and writes a CSV you can open or push to Google Sheets. The Actor charges $1.50 per 1,000 properties on the free plan, so a 100-listing daily check costs about 15 cents a day.
What a listing record contains
Every property comes back with price (the monthly rent for rentals), priceText, currency, pricePerSqm, areaSqm, rooms, postcode, town, state, transaction, propertyType, title, features (for example BALCONY, GARDEN, FREE_OF_COMMISSION), sellerType, agency, listedAt, image, url and listingId. Reduced listings carry oldPrice and priceCutPercent. Private owners are anonymous: no name, no street, no map point, only postcode and town. With includeDetails: true you also get description, floor, yearBuilt, condition, heating, the energy certificate (heatingDemand, heatingDemandClass, energyEfficiencyClass), availableFrom, hasCommission, oneTimeCosts and monthlyCosts.
Step 1: set the filters
locations accepts Austrian cities, towns, Vienna districts, postcodes and states, so "Wien" covers the whole city and "1070" or "Neubau" narrows it to one district. The filters are plain fields:
from apify_client import ApifyClient
client = ApifyClient("<YOUR_APIFY_TOKEN>")
SEARCH = {
"locations": ["Wien"],
"transaction": "rent",
"propertyType": "flat",
"minArea": 50,
"maxPrice": 1500,
"minRooms": 2,
"keyword": "Balkon",
"sortBy": "newest",
"maxListingsPerSearch": 100,
"includeDetails": False,
}
run = client.actor("highbrow_fame/immoscout24-at-properties").call(run_input=SEARCH)
listings = [
item for item in client.dataset(run.default_dataset_id).iterate_items()
if not item.get("error") and item.get("price")
]
print(len(listings), "flats")
If you already have a search set up on immobilienscout24.at with every filter you want, paste its results URL into searchUrls instead and leave the field filters out. sortBy: "newest" is the right order for a feed: the newest 100 of a large search are the ones that changed since yesterday. maxPrice is the monthly rent in EUR.
The same input works outside Vienna. ["Graz", "Linz"] searches two cities in one run, ["Tirol"] a whole state, and because the place search reads "Salzburg" as the state, type the postcode 5020 for the city itself. Each place is one search, so maxListingsPerSearch applies per place. When you reach the shortlist stage, re-run the chosen searchUrls with includeDetails: true to get monthlyCosts, oneTimeCosts, hasCommission, availableFrom and the energy certificate, which together tell you what the flat really costs to move into and to heat.
Step 2: feed mode in 15 lines
The Actor has no built-in only-new switch, so the feed lives in your script: remember every listingId you have delivered in a key-value store in your Apify account and skip the ones you have seen. The first run seeds the memory and reports everything.
store = client.key_value_stores().get_or_create(name="immoscout-wien-feed")
kv = client.key_value_store(store.id)
record = kv.get_record("seen-ids")
seen = set(record["value"]) if record else set()
new_listings = [l for l in listings if l["listingId"] not in seen]
seen.update(l["listingId"] for l in listings)
kv.set_record("seen-ids", sorted(seen))
print(len(new_listings), "new since last run")
Run the script once a day from cron, a GitHub Actions schedule, or any other timer, and new_listings is your feed. If you ever change the filters, give the store a new name so the feed starts clean. Keep maxListingsPerSearch a little larger than a day's worth of new listings for your filters; if len(listings) keeps hitting the limit, raise it.
Step 3: rent per m² and the district comparison
The Actor already fills pricePerSqm when the site shows it. Compute it yourself from price and areaSqm as a fallback, then compare each new flat with the median of its postcode across everything you fetched today:
from statistics import median
from collections import defaultdict
def rent_per_sqm(l):
if l.get("pricePerSqm"):
return round(l["pricePerSqm"], 2)
if l.get("areaSqm"):
return round(l["price"] / l["areaSqm"], 2)
return None
by_postcode = defaultdict(list)
for l in listings:
r = rent_per_sqm(l)
if r:
by_postcode[l["postcode"]].append(r)
district_median = {pc: median(v) for pc, v in by_postcode.items()}
for l in new_listings:
r = rent_per_sqm(l)
l["rentPerSqm"] = r
l["vsDistrictMedianPct"] = (
round((r / district_median[l["postcode"]] - 1) * 100, 1)
if r and l["postcode"] in district_median else None
)
pct = l["vsDistrictMedianPct"]
vs = f"{pct:+}% vs district" if pct is not None else "no district median"
cut = f' (cut {l["priceCutPercent"]}% from {l["oldPrice"]})' if l.get("oldPrice") else ""
print(f'{l["postcode"]} {l["town"]:<10} {l["price"]:>5} EUR {l.get("areaSqm") or "?":>4} m2 '
f'{r} EUR/m2 {vs}{cut}')
print(" ", l["url"])
A flat at -18% against its postcode median deserves a look today, not next week. A priceCutPercent on a listing you saw last week is the other signal worth acting on, so you may want to keep reduced listings in the feed even when the ID is already known.
Step 4: CSV and Google Sheets export
Write the enriched feed to a CSV that opens straight in Excel, Numbers or Sheets. The features list is joined into one cell:
import csv
from datetime import date
FIELDS = ["listedAt", "postcode", "town", "price", "areaSqm", "rooms", "rentPerSqm",
"vsDistrictMedianPct", "oldPrice", "priceCutPercent", "sellerType", "agency",
"features", "url"]
path = f"wien-rent-{date.today()}.csv"
with open(path, "w", newline="", encoding="utf-8") as f:
w = csv.DictWriter(f, fieldnames=FIELDS, extrasaction="ignore")
w.writeheader()
for l in new_listings:
w.writerow({**l, "features": ", ".join(l.get("features") or [])})
print("wrote", path)
For Google Sheets you have two routes. The no-code one: in the Apify Console, save the input as a task and add the Google Sheets integration under the task's Integrations tab, which appends every run's dataset to a sheet. The code one: upload the CSV above with gspread or the Sheets API from the same cron job. The raw dataset is also available as CSV from the API, if you want it without any Python: https://api.apify.com/v2/datasets/<datasetId>/items?format=csv.
Running costs
The Actor charges $0.0015 per property delivered on the free Apify plan, which is $1.50 per 1,000 properties, and less on paid plans down to $1.05 per 1,000. Opening listings for their details costs nothing extra, only time. A 100-listing daily run is $0.15 a day, or about $4.50 a month, and a place ImmoScout24 does not know comes back as a free record rather than a charged one.
