How to Collect Real Estate Data with Proxies

Real estate data drives investment decisions, market analysis, and property technology platforms. Collecting comprehensive data from Zillow, Redfin, Realtor.com, and local MLS systems requires proxy infrastructure to manage rate limits, geographic targeting, and anti-bot defenses.

**Disclaimer**: Review each platform's Terms of Service. Use official APIs (Zillow API, Redfin API) where available. Respect MLS data licensing agreements. This guide covers technical proxy configuration.

Multi-Platform Data Collection

import httpx
import time
import random

@dataclass(frozen=True) class PropertyData: address: str price: str bedrooms: int bathrooms: float sqft: int source: str market: str

@dataclass(frozen=True) class MarketConfig: name: str search_urls: dict[str, str] # platform -> URL

MARKETS = [ MarketConfig( name="Austin TX", search_urls={ "zillow": "https://www.zillow.com/austin-tx/", "redfin": "https://www.redfin.com/city/30818/TX/Austin", }, ), MarketConfig( name="Miami FL", search_urls={ "zillow": "https://www.zillow.com/miami-fl/", "redfin": "https://www.redfin.com/city/11458/FL/Miami", }, ), ]

def collect_market_data( market: MarketConfig, proxy: str, ) -> list[PropertyData]: """Collect listings from all platforms for a market.""" all_listings: list[PropertyData] = []

for platform, url in market.search_urls.items(): time.sleep(random.uniform(5.0, 12.0)) try: with httpx.Client(proxy=proxy, timeout=30, follow_redirects=True) as client: resp = client.get(url, headers={ "User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36", "Accept": "text/html,application/xhtml+xml", "Accept-Encoding": "gzip, deflate, br", }) # Platform-specific parsing would go here pass except Exception: continue

return all_listings ```

Price Trend Monitoring

@dataclass(frozen=True) class PriceTrend: market: str median_price: float avg_price: float listing_count: int collected_at: str

def track_market_trends( markets: list[str], proxy: str, ) -> list[PriceTrend]: """Track pricing trends across multiple markets over time.""" trends: list[PriceTrend] = [] for market in markets: # Collect current listings and compute statistics trends = [*trends, PriceTrend( market=market, median_price=0.0, avg_price=0.0, listing_count=0, collected_at=datetime.utcnow().isoformat(), )] return trends ```

Best Practices

1. Use residential proxies — real estate sites require high-trust IPs
2. **Target US proxies** for domestic platforms
3. Slow pacing — 5-12 second delays between requests
4. **Use official APIs** when available for authorized access
5. Respect MLS licensing — MLS data has specific usage restrictions
