About PropertyData

The app integrates with PropertyData, the UK's most comprehensive property data API, providing:

• Independent market valuations based on comparable sales
• 5-year capital growth trends by postcode
• HM Land Registry title information (plot sizes, tenure)
• Council tax bands
• Crime and flood risk assessments
• Conservation area status

PropertyData requires an API key. Sign up at propertydata.co.uk/api.

Installation

1. Clone the repository

git clone https://github.com/monkeydust/uk-property-analyzer.git
cd uk-property-analyzer

2. Install dependencies

npm install

3. Set up environment variables

Create a .env file in the root directory:

# Google Maps (required for stations, geocoding & commute times)
GOOGLE_MAPS_API_KEY=your_google_maps_api_key

# OpenRouter (required for AI summary)
OPENROUTER_API_KEY=your_openrouter_api_key

# PropertyData (required for market insights & plot sizes)
PROPERTYDATA_API_KEY=your_propertydata_api_key

# Optional: Auth for protected routes
AUTH_SECRET=your_auth_secret
SITE_PASSWORD=your_site_password

4. Initialize the database

npx prisma generate
npx prisma db push

5. Run the development server

npm run dev

Open http://localhost:3000 in your browser.

API Keys Needed

• Google Maps API — Enable Places API, Geocoding API, Distance Matrix API, and Directions API
• PropertyData API — Required for market insights. Packages from £28/month at propertydata.co.uk/api/pricing
• OpenRouter API — Free tier available at openrouter.ai
• TfL API — No key required (free, unauthenticated)

Architecture

The app uses parallel API calls for fast loading:

/api/analyze     → Property data (scrape + geocode) — ~3-5s
  ├→ /api/market-data → Market valuation & risks (parallel)
  ├→ /api/stations    → Rail & tube stations (parallel)
  ├→ /api/commute     → Commute time comparison (parallel)
  ├→ /api/schools     → School attendance data (parallel)
  └→ /api/ai-analysis  → Claude Opus summary (after all data)

The Property Summary and Market Insights cards appear within 3-5 seconds. Stations, commute times, schools, and AI analysis load independently with their own loading spinners.

Market Data Flow

1. Address Matching: The property address is matched to a UPRN (Unique Property Reference Number) via PropertyData
2. UPRN to Title: The UPRN is used to find the HM Land Registry title number
3. Data Aggregation: Multiple PropertyData endpoints are queried in parallel:
   • /valuation-sale — Market estimate based on comparables
   • /growth — 5-year capital growth trends
   • /council-tax — Local authority tax band
   • /crime — Area crime rating
   • /flood-risk — Flood risk assessment
   • /conservation-area — Planning restrictions
4. Fallback Logic: If the exact address isn't in the UPRN database (common with new builds), the system uses nearby properties on the same street (marked with * in the UI)
