# Nigeria Real Estate – Property Sales Transactions

## Dataset Description

Actual property sales with prices, financing methods, buyer types.

**Category**: Property Listings & Sales  
**Rows**: 200,000  
**Format**: CSV, Parquet  
**License**: MIT  
**Synthetic**: Yes (generated using reference data from PropertyPro, Knight Frank, NBS, CBN, FMBN)

## Dataset Structure

### Schema

- **transaction_id**: string
- **city**: string
- **sale_price**: integer
- **financing_method**: string
- **buyer_type**: string
- **transaction_date**: string

### Sample Data

```
| transaction_id   | city       |   sale_price | financing_method   | buyer_type   | transaction_date   |
|:-----------------|:-----------|-------------:|:-------------------|:-------------|:-------------------|
| TXN-0105076      | Benin City |     13469439 | cash               | local        | 2024-09-02         |
| TXN-0809694      | Lagos      |    136502497 | mortgage           | local        | 2022-07-18         |

```

## 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
