LoopNet Commercial Properties Scraper

Pull commercial property listings from LoopNet across the United States, Canada (loopnet.com) and the United Kingdom / international markets (loopnet.co.uk): offices, retail, industrial, multifamily, land, hotels and more. Search by location or paste your own LoopNet URLs. Returns 30+ fields per listing including address, price, size, broker contacts, photos and a full description. Tuned for fast, low-cost, stable runs.

Why this scraper

• Two markets, one actor. Choose loopnet.com (US / Canada) or loopnet.co.uk (UK / international); URL mode auto-detects the site per link.
• Rich results without extra fetches. On the UK site every result already carries title, address, size range, full description and broker names, so the default run is fast and cheap with detail fetching off.
• 30+ fields per listing: location, price, size, year built, building class, broker contacts, photos, coordinates and more.
• Two modes: search by location and filters, or paste specific search / listing URLs (multiple URLs supported).
• Resilient connections. Connections are managed automatically to keep results flowing.
• Predictable cost. One small default result cap, per-record output, and an optional per-listing detail surcharge only when you turn detail fetching on.

How to use

Search the UK site (nationwide industrial to let):

{
  "mode": "search",
  "site": "co-uk",
  "locations": ["united-kingdom"],
  "listingType": "for-lease",
  "propertyType": "industrial-properties",
  "maxListings": 20
}

Search a specific UK city (use the full location slug):

{
  "mode": "search",
  "site": "co-uk",
  "locations": ["london-england--united-kingdom"],
  "listingType": "for-lease",
  "maxListings": 20
}

Search the US site (loopnet.com), on Apify Residential:

{
  "mode": "search",
  "site": "com",
  "locations": ["los-angeles-ca", "new-york-ny"],
  "listingType": "for-sale",
  "propertyType": "office-space",
  "maxListings": 30,
  "proxy": { "useApifyProxy": true, "apifyProxyGroups": ["RESIDENTIAL"] }
}

Paste your own URLs (site auto-detected per link). The price, size and sort filters still apply to each pasted search URL, so you can narrow a link you copied out of the browser:

{
  "mode": "url",
  "urls": [
    "https://www.loopnet.co.uk/search/commercial-property/london-england--united-kingdom/for-rent/",
    "https://www.loopnet.co.uk/search/office-space/manchester-gtm--united-kingdom/for-rent/"
  ],
  "minSqft": 2000,
  "sortBy": "size-desc",
  "maxListings": 50
}

Input parameters

Parameter	Type	Default	Description
mode	string	search	search builds URLs from the search fields below; url passes through your URLs. The price, size and sort filters apply in both modes.
site	string	com	com for US / Canada, co-uk for UK / international. Auto-detected in URL mode.
locations	array	["los-angeles-ca"]	Search mode only. Location slugs. US: los-angeles-ca. UK: united-kingdom or london-england--united-kingdom. Ignored in URL mode, where each pasted URL carries its own location.
listingType	string	for-sale	Search mode only. for-sale, for-lease (For Rent on the UK site), or auction (US only). Ignored in URL mode, where the listing type is read from each pasted URL.
propertyType	string	all-commercial	Search mode only. Office, retail, industrial, multifamily, land, hotels, and more. Ignored in URL mode, where the property type is read from each pasted URL.
minPrice / maxPrice	integer	none	Applies in both search mode and URL mode. Price range, applied to every results page walked, including pasted search URLs. Listings with no total price shown (a per sq ft or per month rent) are kept.
minSqft / maxSqft	integer	none	Applies in both search mode and URL mode. Size range, applied to every results page walked, including pasted search URLs. Listings with no size shown are kept.
sortBy	string	default	Applies in both search mode and URL mode. Most recent, price or size ordering of the listings collected from each results page.
urls	array	sample	URL mode only. Multiple URLs supported. The search-mode fields above are ignored, but the price, size and sort fields still apply to every pasted search URL. A pasted individual listing URL is saved as-is, unfiltered.
fetchDetails	boolean	false	Adds coordinates, street, broker phone and JSON-LD fields per listing.
maxPages	integer	(empty)	Safety ceiling on results pages per location/URL. Leave empty to walk every result page.
maxListings	integer	20	Stop after this many listings. 0 = unlimited.
resumeFromRunId	string	(empty)	A previous run ID or dataset ID to continue a full-catalogue walk across separate runs. Listings already collected there (matched by id) are skipped, so this run only saves the new ones.
incrementalMode	boolean	false	Turn on for recurring/scheduled monitoring of the SAME search. Classifies each listing as NEW/UPDATED/UNCHANGED/REAPPEARED/EXPIRED against the actor's own remembered state, instead of you pasting a run/dataset ID every time.
stateKey	string	(empty)	Incremental mode only. Names a monitoring campaign so its state stays stable, or to deliberately share state across differently-configured runs. Leave empty to derive a key automatically from the site/locations/filters/fetchDetails.
emitUnchanged	boolean	false	Incremental mode only. Also return (and bill) listings that have not changed since the last run, marked UNCHANGED.
emitExpired	boolean	false	Incremental mode only. Also return (and bill) listings that were tracked before but are no longer found, marked EXPIRED. Only produced once a run fully scans the tracked search.
proxy	object	Residential	Connection settings, see below.

Resuming a full-catalogue walk

For an unbounded pull (maxPages empty, maxListings: 0), two things protect a long run:

• resumeFromRunId lets you continue in a brand-new run: paste the ID of a previous run (or its dataset), and this run skips every listing id already saved there, appending only new listings.
• A checkpoint is saved automatically as the run progresses. If the run is interrupted by an Apify platform migration or you click Resurrect on a failed run, it picks back up in the same run without re-saving (or re-charging for) listings it already collected. No input is needed for this; it's automatic.

Incremental & dedup mode (recurring monitoring)

Distinct from resumeFromRunId above, which continues ONE specific interrupted run. incrementalMode is for scheduling this actor to run the SAME search again and again (daily/weekly) and getting only what changed:

• The first run returns every matching listing marked changeType: "NEW".
• Later runs normally return only NEW, UPDATED, and REAPPEARED listings — unchanged listings are suppressed (not pushed, not billed) unless you turn on emitUnchanged.
• Every dataset row gains changeType, changedFields, firstSeenAt, and lastSeenAt while incremental mode is on. With it off, output is unchanged.
• State is kept per stateKey (or an automatic hash of site/locations/filters/fetchDetails) in a dedicated key-value store, so it never costs extra requests against LoopNet.
• A detail page is still fetched (and used to compute the change fingerprint) for a listing that turns out UNCHANGED, but that listing is neither pushed nor charged the detail-enrichment surcharge.
• emitExpired only fires once a run has fully scanned the tracked search — a page-capped, resumed, or partial run leaves previously-tracked listings' state as-is instead of guessing they are gone.

Send results into your apps (MCP connectors)

Optionally pipe the scraped results into the apps you already use, via Model Context Protocol (MCP) connectors. This is an extra delivery step after the scrape — the Apify dataset is never changed.

What gets written to the connector: a condensed, human-readable summary of each record — not the full JSON. Each item becomes one entry with a title and its key fields flattened to plain text. The complete record always stays in the Apify dataset.

1. Authorize a connector once under Apify → Settings → Integrations (Notion, Linear, Airtable, or Apify).
2. Select it in the "Pipe results into your apps" input field. (If the picker is empty, you haven't authorized a connector yet.)
3. For Notion, also set notionParentPageUrl to the page where items should be created.

The connection is mediated by Apify's MCP proxy, so this actor never sees your third-party credentials. Leave the field empty to skip.

Connection

This actor needs Apify Residential proxy (Starter plan or higher). Both sites work on the Residential default; regional connections are handled automatically, so leave the connection as is for most runs.

• loopnet.co.uk (UK / international) runs on Apify Residential out of the box.
• loopnet.com (US / Canada) also runs on Apify Residential. If a US run occasionally returns zero results during heavy traffic periods, simply re-run, or optionally supply your own residential proxy URLs in the connection field (proxyUrls) for extra headroom.

If a run returns zero results, the dataset includes a single record noting what to adjust.
