CoreLogic / Cotality Data — Sourcing Notes

CoreLogic — rebranded Cotality — is a B2B property-data aggregator that resells AVM, sold, tax and ownership data rather than listing properties, and it is licensed under contract, not scraped. It is the backbone of US property data and is also strong in Australia and New Zealand (RP Data, including the HVI house-value index). PropAPIS treats it as a sourcing/partnership reference, not a parse target.

Platform Overview

Market Position

• The backbone of US property data; strong AU/NZ presence via RP Data (incl. the HVI house-value index)
• A data aggregator that resells structured property data rather than operating a consumer listings portal
• Licensed B2B — acquired via paid contract, not scraping (Homesage data-provider review, 2026)
• A potential sourcing partner or competitor to PropAPIS, depending on use case

Why It Is Not a Parse Target

Cotality does not publish a consumer listings site to extract — it sells curated datasets and APIs under license. The right way to obtain its data is a B2B contract, so PropAPIS documents it here for sourcing and competitive context rather than offering an extraction endpoint.

Coverage

Data Coverage:

• United States (nationwide property records)
• Australia and New Zealand (RP Data, HVI)
• Global property and risk datasets
• AVM, tax, ownership and sales-history fields

Data Fields Available

Cotality holds deep structured property data, typically licensed in bulk or via its own B2B API:

Valuation & Market Data

• AVM: Automated valuation models
• Price Index: HVI house-value index (AU/NZ)
• Market Trends: Suburb and regional trends
• Sales History: Historical transaction data

Property & Ownership Data

• Property Attributes: Beds, baths, area, land
• Tax: Assessed values and tax records (US)
• Ownership: Title and ownership records
• Sold Data: Recent sale prices

Note: PropAPIS does not extract Cotality data. These fields describe what Cotality licenses directly; obtain them through a Cotality B2B agreement.

API Endpoints

Cotality exposes its data through its own paid B2B API and bulk-data products — not through PropAPIS extraction. The snippets below illustrate how you might integrate Cotality-licensed data alongside PropAPIS listing data in your own pipeline.

Combine Licensed Data With PropAPIS Listings

from propapis import PropAPIS
 
api = PropAPIS(api_key='your_api_key')
 
# PropAPIS provides live listings; Cotality (licensed) provides AVM/sold.
# Fetch listings from a portal PropAPIS does extract, then enrich.
listings = api.platforms.realestate_au.search(state='NSW', purpose='for-sale')
 
for listing in listings[:5]:
    print(f"{listing.title} - AUD {listing.price:,}")
    # enrich with your licensed Cotality AVM here (B2B contract required)

Quick Start

from propapis import PropAPIS
 
# PropAPIS does not resell Cotality data — license it from Cotality directly.
# Use PropAPIS for live listings and enrich with your Cotality dataset.
api = PropAPIS(api_key='your_api_key')
 
listings = api.platforms.realestate_au.search(state='VIC', purpose='for-sale')
for listing in listings[:5]:
    print(f"{listing.title} - AUD {listing.price:,}")

import { PropAPIS } from 'propapis';
 
// PropAPIS does not resell Cotality data — license it from Cotality directly.
// Use PropAPIS for live listings and enrich with your Cotality dataset.
const api = new PropAPIS({ apiKey: 'your_api_key' });
 
const listings = await api.platforms.realestateAu.search({
  state: 'VIC',
  purpose: 'for-sale',
});
 
listings.slice(0, 5).forEach((l) => {
  console.log(`${l.title} - AUD ${l.price.toLocaleString()}`);
});

# PropAPIS does not resell Cotality data — license it from Cotality directly.
# PropAPIS provides live listings you can enrich with a Cotality dataset.
