NL Student Housing Aggregator (123Wonen, Rotsvast, ViaDaan, HouseHunting + Groningen offices)

Get current room/studio/apartment rental listings from independent Dutch rental offices in Groningen, Utrecht and Nijmegen — sourced directly from national franchise websites (123Wonen, Rotsvast, ViaDaan, HouseHunting) plus 15 independent Groningen offices (Gruno Verhuur, Bulten Vastgoed, DC Wonen, Gout Beheer, K&P Makelaars, Van der Meulen Makelaars, Solide Verhuur, 050Vastgoed, Thuis Verhuurmakelaars, Desegno, Lucas Klamer Makelaardij, ben-s.nl verhuur en beheer, II DAM B.V., Nova Vastgoed Groningen, F1 & Riant Makelaars), not from Kamernet/Pararius/Funda, which this Actor deliberately does not scrape.

When should an AI agent use this?

• "What rooms/apartments are currently available for rent in Groningen through 123Wonen?"
• "Show me the cheapest studios for rent in Utrecht right now."
• "Is there any student housing available in Nijmegen under €900 per month?"
• "Compare current rental prices per m² across Groningen, Utrecht and Nijmegen."
• "Which currently listed apartments are available for rent immediately (per direct)?"
• "Find me a student room in Groningen under €600 per month."

What this Actor does

• Fetches current rental listings directly from the public sitemaps and listing pages of four national rental franchises that each operate offices in multiple Dutch student cities: 123Wonen, Rotsvast, ViaDaan and HouseHunting — covers Groningen, Utrecht and Nijmegen, selectable per run.
• Additionally covers 15 independent, Groningen-only rental offices with real, deeper local inventory: Gruno Verhuur, Bulten Vastgoed, DC Wonen, Gout Beheer, K&P Makelaars, Van der Meulen Makelaars, Solide Verhuur, 050Vastgoed, Thuis Verhuurmakelaars, Desegno, Lucas Klamer Makelaardij, ben-s.nl verhuur en beheer, II DAM B.V., Nova Vastgoed Groningen and F1 & Riant Makelaars — each a separate, custom-built website with no shared structure, so each gets its own adapter (see Changelog). 4 of these (Gout Beheer, K&P Makelaars, Van der Meulen, Solide Verhuur) require rendering the page in a headless browser to read the listings, so runs including them are slower per listing than the sitemap-based sources.
• Normalizes wildly different underlying data (every source runs its own, unrelated website/CMS) into one consistent output schema: address, price, surface area, bedrooms, availability, furnished status.
• Skips listings already marked as rented ("Verhuurd") on sources that keep showing them after the fact (Gout Beheer, K&P Makelaars, Van der Meulen) — not useful for someone looking for a current vacancy.
• Explicitly does not scrape Kamernet, Pararius, Funda or Huurwoningen.nl (the large listing platforms) — those are used by independent offices only as one of several places to list, and have their own restrictions on automated access. This Actor goes directly to the offices' own public listings instead.
• Skips large institutional/waitlist housing providers (e.g. SSH&, Idealis, Lefier) and purpose-built student accommodation operators (e.g. Xior, Holland2Stay) — those operate a closed waitlist/lottery model, not a free-market listing.

Input

Field	Type	Description
steden	string[]	Which cities to check: groningen, utrecht, nijmegen. Default: all 3.
bronnen	string[]	Which sources to check: 123wonen, rotsvast, viadaan, househunting (national, any city); gruno, bulten, dcwonen, goutbeheer, kpmakelaars, vandermeulen, solideverhuur, vijftigvastgoed, uwthuis, desegno, lucasklamer, bens, iidam, novavastgoed, riantmakelaars (independent Groningen-only offices, ignored for other cities — goutbeheer/kpmakelaars/vandermeulen/solideverhuur are slower, browser-rendered sources). Default: all 19.
maxPerBron	integer	Optional cap on listings fetched per source per city — useful for a cheap test run. Leave empty for no limit.
nieuwSinds	string (YYYY-MM-DD)	Optional: only include listings this Actor first saw on or after this date. Sources don't publish a "posted on" date, so this Actor tracks each listing's first-seen date itself, persisted across runs. The very first run (no history yet) always shows everything regardless of this setting.
maxPrijs	integer	Optional: only include listings priced at or below this amount (€/month). Listings with no stated price are excluded when this is set — never a guess.
minOppervlakte	integer	Optional: only include listings sized at or above this many m². Listings with no stated size are excluded when this is set, same reasoning as maxPrijs.
typen	string[]	Optional: only include these property types: kamer, studio, appartement, onbekend. Leave empty for all types.

Output

One flat JSON record per listing found:

{
  "stad": "groningen",
  "kantoor": "Gruno Verhuur",
  "bron": "gruno",
  "bron_url": "https://www.grunoverhuur.nl/",
  "titel": "studentenkamer aan de Paterswoldseweg",
  "type": "kamer",
  "adres": "Paterswoldseweg 96",
  "postcode": "9727 BG",
  "plaats": "Groningen",
  "prijs_pm": 700,
  "oppervlakte_m2": 15,
  "aantal_kamers": null,
  "beschikbaar_vanaf": null,
  "gemeubileerd": null,
  "url": "https://www.grunoverhuur.nl/woningaanbod/huur/groningen/paterswoldseweg/96",
  "opgehaald_op": "2026-07-20T16:31:02.486Z",
  "eerst_gezien_op": "2026-07-20"
}

Note: for the 4 national franchises (123Wonen/Rotsvast/ViaDaan/HouseHunting), postcode is consistently null — none of them publish the exact postal code or house number on the public listing page (a common lead-generation practice, so interested renters have to make contact). The independent Groningen offices generally do publish the full postcode. beschikbaar_vanaf, gemeubileerd and aantal_kamers are null whenever the source page doesn't state them clearly — this Actor never guesses; a null means "not stated", not "no"/"unfurnished"/"zero". A price is also null (never 0) when a source shows no real price.

opgehaald_op is always the timestamp of the current run — it does not indicate how long a listing has been available. eerst_gezien_op (date only) is the first date this Actor itself observed this exact listing URL, tracked in a persistent store across runs — use nieuwSinds in the input to filter on it.

Use cases

• Students/renters checking current availability across multiple independent offices without visiting each one's website separately.
• Market research on rental price/m² trends across student cities.
• Feeding a housing search agent or notification workflow with fresh listings.

Legal

Sourced from each source's own public sitemap and listing pages. robots.txt was checked for all 19 sources and none disallow the listing/object paths used here. Only publicly listed rental information is collected (address street, price, size, availability) — no personal data, no agent/employee names or photos. Kamernet, Pararius, Funda and Huurwoningen.nl are deliberately excluded (large platforms, own access restrictions) — Pararius was used only during research to identify which independent offices exist, never as a scrape target for this Actor.

FAQ

Q: Why these 19 sources, and not every independent office per city? A: 123Wonen/Rotsvast/ViaDaan/HouseHunting are the franchises confirmed to run on a single national website covering multiple cities, so one source reliably covers 3 cities at once. The 15 Groningen offices are the highest-confidence independent offices identified so far for that city out of a much longer candidate list — one Tier-1 candidate (Groningse Panden Beheer) and several Tier-2 candidates were investigated in depth but turned out to have no publicly browsable listings, a wrong business model (short-stay, referral-only to Kamernet/Pararius/Funda), or a technical block that a normal browser header doesn't solve — not included; see Changelog for the full accounting. Dozens of other small independent offices still exist per city, each on its own unique, custom-built website with no shared structure — adding more is possible but requires a dedicated adapter per office, an ongoing expansion.

Q: Why is postcode empty for some sources but not others? A: The 3 national franchises deliberately don't publish the exact postal code/house number (a lead-gen choice by those offices). The independent Groningen offices generally do publish it — this Actor reports exactly what each source makes public, nothing more.

Q: Does this include Kamernet/Pararius/Funda listings? A: No, and it never will by design — those are large platforms with their own access restrictions, and this Actor exists specifically to surface listings from independent offices instead.

Q: Why do some runs return few or zero ViaDaan/Gout Beheer results? A: Both are small offices — they may simply have no current listings for the requested city right now. Gout Beheer's currently listed objects have all been observed marked "Verhuurd" (already rented) at time of writing — this Actor correctly skips those rather than reporting stale vacancies, so 0 results on a given day is expected behavior, not a bug.

Q: How do I get only new listings since my last check? A: Set nieuwSinds to a date (YYYY-MM-DD). None of the underlying sources publish a "posted on" date, so this Actor tracks each listing URL's first-seen date itself in a persistent store shared across runs, and filters on that. The very first run you do always shows everything (there's no history yet) and records today as the first-seen date for every listing found — from the next run onwards, nieuwSinds lets you skip listings you've already seen before that date.

Q: How do I narrow results by price, size or type? A: Use maxPrijs, minOppervlakte and/or typen. All three filter on the already-normalized fields, so they work the same way across every source. A listing missing the filtered field (e.g. no stated price) is excluded rather than guessed at when that filter is active.

Q: Why do some runs take noticeably longer than others? A: 5 sources (Gout Beheer, K&P Makelaars, Van der Meulen Makelaars, Solide Verhuur, ViaDaan) require rendering pages in a headless browser to read their listings — 4 because the listing data itself is client-side rendered, and ViaDaan because reading its full national listing (not just the first page) requires repeatedly triggering its "load more" component. Excluding those 5 from bronnen gives a faster run using only the sitemap-based sources.

Changelog

0.8.0

• Added maxPrijs, minOppervlakte and typen input filters, so a run can return only listings that actually match what you're looking for instead of everything found. A listing missing the filtered field is excluded rather than guessed at.
• Fixed ViaDaan's long-standing pagination gap: previously only the first ~10 of its ~64 national listings were read (the rest loaded via a Livewire "infinite scroll" component with no page-number URLs to follow). ViaDaan now runs through a headless browser and repeatedly triggers the underlying Livewire component method directly ($wire.loadMore()) until no new listings appear — scroll-event simulation didn't reliably trigger the site's IntersectionObserver in headless Chromium, but calling the component method directly does and is faster besides.

0.7.0

• Added a nieuwSinds input setting (YYYY-MM-DD) to only return listings first seen by this Actor on or after a given date. None of the 19 sources publish a "posted on" date themselves, so this Actor now tracks each listing URL's first-seen date in a persistent, cross-run key-value store and adds it to every output record as eerst_gezien_op. The first run you do always shows everything (no history exists yet) and establishes the baseline; subsequent runs can filter on it.

0.6.0

• Added 3 more independent Groningen-only offices from a deeper follow-up investigation of the ~15 Tier-2 candidates left over from 0.5.0: II DAM B.V., Nova Vastgoed Groningen and F1 & Riant Makelaars. All 3 are plain-HTTP sources (no headless browser needed).
• Of the 12 candidates actually investigated in depth this round, 9 were confirmed not usable and excluded: wrong business model (Schove Groep/Schovast and Confides Verhuur only refer to Funda/Pararius/Kamernet instead of hosting their own listings; Overnachteninstijl.nl is confirmed short-stay/holiday rental, not regular housing), technical blocks (Stadeo Vastgoed renders price/size/rooms through a client-side widget with no static fallback; KD Vastgoed returns HTTP 403 regardless of User-Agent, likely an IP/WAF block, not solved by browser rendering), or currently-empty inventory despite a working mechanism (Bakker Real Estate, Reinders Makelaars, Midas Vastgoed, PROPRIETAS Vastgoedmanagement) — see PROJECTINFORMATIE.txt for the full per-office accounting.
• F1 & Riant Makelaars' own "rental listings" page currently mixes already-rented listings (struck-through price) with for-sale listings ("k.k.") — both are explicitly skipped, so 0 results for this source is expected at the time of writing, not a bug (comparable to the existing Gout Beheer behavior).

0.5.0

• Added 5 more independent Groningen-only offices found via a "Tier 2" triage of ~39 smaller candidate offices (4 parallel research passes): 050Vastgoed, Thuis Verhuurmakelaars, Desegno, Lucas Klamer Makelaardij and ben-s.nl verhuur en beheer. All 5 are plain-HTTP sources (no headless browser needed). Gruno Verhuur, 050Vastgoed, Thuis Verhuurmakelaars and Desegno were found to share the same sitemap naming convention (sitemap_listings_res_rent.xml, likely a common real-estate software vendor) even though each uses different page markup — only the listing-discovery logic could be shared, not the data-extraction itself.
• Triaged ~39 smaller candidate offices; confirmed several as not usable for this Actor: some only list via Kamernet/Pararius/Funda (already excluded platforms), some require a login portal, one ("Ad Hoc Groningen") turned out to be the same nationwide anti-squatting/vacancy-management chain already excluded elsewhere, and a few (Nijestee, Xior Student Housing) operate a waitlist/institutional booking model rather than free-market listings.
• Fixed a surface-area bug on Desegno: some listings show both plot size ("perceeloppervlakte") and actual living space ("gebruiksoppervlakte") in that order — the parser previously picked the larger plot size instead of the living space.

0.4.0

• Added a 4th national franchise: HouseHunting, with a Groningen office (also active nationally, but only verified/enabled for Groningen so far). Uses ?filter_location=<stad> on its listing index, which doesn't appear to filter the total result count server-side but does surface the requested city on the first page — results are filtered client-side by matching the city name in the listing URL.
• Investigated one more Tier-1 Groningen candidate, Groningse Panden Beheer — found no publicly browsable listings on their site at all (no sitemap, no listing links, no data-loading network request even after rendering the page) despite being one of the largest managed portfolios in the original research. Not included; documented as a dead end, not a bug.
• Fixed parseBeschikbaarVanaf missing dates where the "vanaf"/"per" label appears before a colon (e.g. HouseHunting's "Beschikbaar per: 01-12-2023") — previously only handled the label appearing after any colon/whitespace, not before.

0.3.0

• Added 4 more independent Groningen-only offices: Gout Beheer, K&P Makelaars, Van der Meulen Makelaars and Solide Verhuur. These 4 require a headless browser (Playwright) to read their client-side-rendered listings — the first browser-based source in this Actor, alongside the existing plain-HTTP sources.
• Added automatic skipping of listings already marked "Verhuurd" (rented) on sources that keep showing them.
• Fixed prices being reported as 0 instead of null when a source shows a broken/placeholder price for a no-longer-active listing (seen on Solide Verhuur).
• Fixed surface area parsing for decimal values (e.g. "94.00 m²") that were previously truncated to the decimal part only (e.g. read as 0 instead of 94).

0.2.0

• Added 3 independent Groningen-only offices: Gruno Verhuur, Bulten Vastgoed and DC Wonen — each a custom-built website with its own adapter (no shared CMS between them or with the franchises).
• Fixed a Gruno Verhuur sitemap bug: category/filter pages (e.g. .../type-appartement) were mixed into the listings sitemap and misread as individual objects, producing a duplicate. Now filtered out.

0.1.0

• Initial release: 123Wonen, Rotsvast and ViaDaan for Groningen, Utrecht and Nijmegen. ViaDaan reads only the first page of its national listing index (no pagination yet) — a known, documented limitation, not a bug.
