Zillow is the dominant US residential real estate portal with 110 million home listings. Since the Zestimate API was deprecated in 2021, scraping is now the primary method for extracting property valuations, listing data, and market trends at scale.

Realtor.com is operated by Move, Inc. under license from the National Association of Realtors and provides listing data directly from 580+ MLS systems. It offers among the most comprehensive and frequently updated US listing data available.

Redfin combines brokerage data with direct MLS feeds to provide some of the most accurate and timely US listing information. Its Redfin Estimate is widely used by investors, and the platform offers detailed market trend data by neighborhood.

Rightmove dominates the UK property market with more listings than any competitor. It is the primary research tool for UK estate agents, investors, and analysts tracking regional price trends and rental yields across England, Scotland, and Wales.

Multiple Listing Services remain the backbone of US real estate data. With 580+ local systems, each MLS serves a specific geographic area and contains the most detailed and up-to-date listing information available, including properties not yet syndicated to consumer portals.

Aggregate listing prices, sold data, and market trends across multiple portals to build comprehensive comparable analyses. Investors use mobile proxies to monitor hundreds of properties simultaneously across Zillow, Redfin, and local MLS systems, tracking price movements and identifying undervalued assets before they are widely noticed.

Collect rental listing data from Zillow Rentals, Apartments.com, and local portals to calculate gross yields, cap rates, and cash-on-cash returns by neighborhood. Pair rental data with purchase price trends to identify markets with the strongest investor returns.

Build targeted lead lists of motivated sellers, expired listings, and FSBO properties by monitoring portal activity patterns. Mobile proxies enable continuous monitoring of new listings, price reductions, and days-on-market signals across entire markets without triggering anti-bot measures.

With 8 million+ Airbnb listings worldwide, short-term rental hosts and property managers use scraping to monitor competitor pricing, occupancy rates, and seasonal trends. Mobile proxies enable reliable data collection from Airbnb, VRBO, and Booking.com for revenue optimization and market entry analysis.

Institutional investors and REITs need comprehensive market data across hundreds of markets simultaneously. Mobile proxies enable parallel data collection from consumer portals, public records, and commercial platforms to feed valuation models and acquisition pipelines.

Realtor.com uses Cloudflare's full protection suite including JavaScript challenges, CAPTCHA triggers, and behavioral analysis. Cloudflare maintains an extensive database of known proxy and VPN IP ranges that are automatically challenged or blocked.

Redfin employs a custom-built detection system that combines aggressive rate limiting with session analysis. The system tracks request patterns, monitors for automated browsing signatures, and enforces strict per-IP request quotas that severely limit data collection.

Rightmove uses JavaScript-based bot detection that evaluates browser capabilities, rendering behavior, and interaction patterns. Non-UK IP addresses receive additional scrutiny, and automated access patterns trigger blocking across sessions.

• For AU ownership data: Use state Land Registry services (e.g., NSW LRS)
• For UK sold prices: Use HM Land Registry Price Paid Data (official dataset)
• For US public records: County assessor/recorder portals (e.g., Clark County NV)
• Zillow Zestimate API deprecated 2021 -- scraping requires compliance with Zillow ToS

CoStar dominates commercial real estate data with $2.2B revenue (2024). Its platform covers office, retail, industrial, multifamily, and hospitality properties across the US and UK, providing valuations, lease comps, and market analytics used by institutional investors and brokers.

LoopNet, owned by CoStar, is the most trafficked commercial real estate marketplace in the US. It lists properties for sale and lease across all commercial categories, and its data feeds institutional-grade investment analysis and deal sourcing platforms.

Crexi has grown rapidly as a CoStar alternative, offering commercial listing data, auction platforms, and analytics. It is particularly strong in retail, industrial, and net-lease properties, and has gained market share among smaller brokerages and individual investors.
