Data Generation Methodology

This dataset was synthetically generated using:

1. Reference Sources:

   • PropertyPro & Nigeria Property Centre - listing prices, property types, locations
   • Knight Frank & Pam Golding - market reports, prime property indices, investment analysis
   • NBS (National Bureau of Statistics) - real estate GDP contribution, construction statistics
   • CBN (Central Bank of Nigeria) - mortgage lending data, interest rates
   • FMBN (Federal Mortgage Bank) - NHF contributions, mortgage disbursements
   • State land registries - title processing times, transaction volumes

2. Domain Constraints:

   • Location pricing hierarchy (Lagos: Ikoyi > Lekki > Surulere > Ikorodu)
   • Property types (detached, semi-detached, terrace, flat, bungalow)
   • Title types (C of O, Deed of Assignment, Governor's Consent)
   • Mortgage characteristics (3% penetration, 18-25% interest, 60-70% LTV)
   • Rental yields (4-10% by location tier)

3. Quality Assurance:

   • Distribution testing (price per sqm follows lognormal within tiers)
   • Correlation validation (location-price r > 0.7, size-price r > 0.8)
   • Causal consistency (property valuation models, market dynamics)
   • Multi-scale coherence (property → neighborhood → city aggregations)
   • Ethical considerations (representative, unbiased, privacy-preserving)

See QUALITY_ASSURANCE.md in the repository for full methodology.

Use Cases

• Machine Learning: Property price prediction, location scoring, investment ROI forecasting
• Market Analysis: Price trends, supply-demand dynamics, market segmentation
• Investment: Rental yield optimization, portfolio analysis, risk assessment
• Urban Planning: Housing demand forecasting, infrastructure impact analysis
• Research: Real estate market dynamics, affordability studies, diaspora investment patterns

Limitations

• Synthetic data: While grounded in real distributions from PropertyPro/Knight Frank/NBS, individual records are not real transactions
• Simplified dynamics: Some complex interactions (e.g., negotiation, market sentiment) are simplified
• Temporal scope: Covers 2022-2025; may not reflect longer-term trends or future policy changes
• Title issues: Models title problems statistically but doesn't capture full legal complexity
