LoopNet is one of the most trusted sources for commercial real estate in the U.S. It focuses exclusively on offices, retail, industrial, and other commercial properties.
With our LoopNet scraper, we collect listing data for you - structured, accurate, and tailored to your needs.
We run the whole job. You name the markets, property types and cadence; we build the crawler, extract and validate the fields, and deliver on schedule as CSV, JSON, XLSX, a database load or an API endpoint your systems can poll. The scraping, the retries, the proxying and the monitoring are ours to operate.
Common shapes: a one-off market snapshot for a feasibility study; a weekly refresh of availabilities across a set of submarkets; a nightly delta of new, changed and removed listings; or a backfill plus ongoing runs so you hold a history rather than a moment. Two-table output is the usual choice, one row per building listing and one row per available space, joined on listing ID.
When the markup moves, we fix the parser. That is not your maintenance problem.
A commercial record is not a house record with bigger numbers. The unit of interest is often a space inside a building rather than the building itself, and the money is quoted per square foot rather than as a single figure. Our LoopNet scraper keeps both levels and joins them on the listing ID.
At the building level we take:
At the space level each availability gets its own row: floor and suite label, size in SF, lease term, rental rate, space use, build-out condition and the date the space becomes available. The rate is stored with its unit, because the same space can be displayed as $/SF/YR, $/SF/MO, $ Amt/YR or $ Amt/MO, and a rent without its unit is worthless. Where the rate reads Upon Request or the term reads Negotiable, we record that text rather than inventing a figure. Lease type, where the listing names one, is carried through as written: NNN, modified gross or full service.
The site does not serve plain HTTP clients. On 31 August 2026 a direct command line request for the site's own robots.txt returned HTTP 403 from the Akamai edge, so the practical starting point is a rendered page fetched at a polite rate. We do not attempt to defeat bot protection, we do not solve CAPTCHAs, and we do not register or log in. Everything we collect is what an anonymous visitor sees.
Search paths follow /search/property-type/market/for-lease/ or /for-sale/, where the market segment accepts a state, a city or a submarket such as downtown-los-angeles-los-angeles-ca. Pagination is a numeric path segment appended to that path. On the search pages we read, the counter stopped at 500 results, 25 per page across 20 pages, in markets the site itself described as holding thousands of properties. So we never run one query per city. Each market is split by property type, submarket, size band and price band, and the results are de-duplicated on listing ID.
Detail pages sit at /Listing/street-city-state/numeric-id/. That numeric ID is the stable join key between runs, so a suite whose rent moves can be matched to the same building next week. Robots.txt disallows several paths, including /broker/, /market/, /locations/ and /map/, and we respect those directives. Output is limited to listing and commercial property data; broker and brokerage names appear on the public listing, and broker contact fields can be excluded from the delivery on request.
LoopNet is a public marketplace for commercial property in the United States. Brokers, owners and leasing agents advertise buildings, suites, land and investment offerings there, and anyone can browse the result without signing in. The site is operated by CoStar Group, which also runs the CoStar subscription research service, Apartments.com, Homes.com, Ten-X and Land.com.
That ownership matters for anyone planning to scrape LoopNet. CoStar sells commercial property research as a paid product. The marketplace is a separate thing: an advertising surface where the listing broker decides what to publish. The two are not interchangeable. Public pages carry the advertised record, not the subscription research database, and we make no attempt to reach the latter.
LoopNet also runs its own membership and advertising tiers. Its terms state that users and basic members receive a subset of the properties matching a search, and that seeing all results for a search requires a premium membership. Listings are sold in named ad packages, so how prominently a property appears is partly a paid decision. A public crawl therefore reflects the public marketplace view on the day it ran. That is the honest boundary of any LoopNet data collected without an account, and we would rather state it here than let you find it later against your own market count.

Availability ages fast. A suite leases, a rent gets cut, an owner pulls a building, and the marketplace reflects it within days. Reading that on a schedule is what turns a page into a dataset.
Acquisition and investment teams screen for-sale inventory by market, property type, price band and cap rate, then push a shortlist into their own model. Landlords and asset managers watch competing availabilities in a submarket to see what nearby buildings quote per square foot and how long a suite has sat. Tenant representatives build option lists from the space table rather than the building headline, because a 3,000 SF requirement cares about suites, not about the tower they sit in.
Appraisers, lenders and market research groups use repeated snapshots to measure direction: availabilities appearing, asking rents moving, listings leaving the market. Site selection and franchise development teams filter retail and industrial LoopNet listings by size, zoning and trade area. Proptech products use the feed to keep a market map current between vendor deliveries.
In every case the value sits in the repeat. A single run is a list. A year of runs is a time series.

Real estate teams work in a fragmented data landscape. The sites that drive demand in Boston look nothing like the ones that matter in Berlin, São Paulo, Dubai, or Mumbai.
Real estate teams are operating in a data environment that is bigger, faster, and more fragmented than ever. Listings go live and disappear in hours, price cuts happen quietly, and the portals that matter most in each country are rarely the same global “top 5.”
Real estate web scraping: a powerful tool for data collection and analysis. Learn how to choose the right data collection method and benefit from real estate web scraping
ScrapeIt is a managed web scraping agency. We are not selling a library, a plugin or a browser extension. We build the crawler, run it on our own infrastructure, watch it, repair it when the source changes, and hand over clean data in the format and on the schedule you asked for.
We work inside what a site publishes to the public, respect robots directives, and describe plainly what a source does and does not expose. If a requirement cannot be met honestly, we say so before the project starts.
No. LoopNet does not publish a public API for listing data, and we found no developer portal or API documentation on the site. The pages under /solutions/ sell advertising packages and LoopLink, a search tool that lets a brokerage display its own inventory on its own website; neither is an open data feed. Anything marketed elsewhere as a LoopNet API, including ours, is a crawler with an endpoint in front of it. We are happy to give you that endpoint, but the source underneath is the public web page.
No. Both belong to CoStar Group, but they are different products. CoStar sells a paid research and analytics service. LoopNet is the public marketplace where brokers advertise space and buildings. We collect only public marketplace pages. LoopNet's own terms state that users and basic members receive a subset of the properties matching a search, and that a premium membership is needed to see every result, so a public crawl returns the public view rather than a complete national inventory.
As two linked tables. One row describes the building: address, size, class, year built, property type, broker and brokerage. Then one row per available space: floor and suite, size in SF, term, rental rate with its unit, space use, condition and availability date. One office listing we read carried twelve available spaces under a single listing ID, each with its own size and its own rate. Flattening that into one row per building throws away the part tenant reps and analysts actually work with.
We record what is shown and nothing more. Many records display Upon Request instead of a rental rate and Negotiable instead of a term, and some listings put documents and further detail behind a registration prompt. We do not create accounts, do not log in, and do not collect anything behind that prompt. Fields that are not public come back empty, with the on-page wording preserved so you can see why they are empty.
Daily, weekly or monthly, depending on how many markets you cover and how fast they move. Because the numeric listing ID is stable, consecutive runs can be compared: new availabilities, asking rent changes, spaces disappearing, and listings that flip to the state where the page says the property is no longer advertised on LoopNet.com. Listing pages also print a date on market and a last updated date, which we keep as recorded. Any count we quote is dated to the run that measured it.
