## Why Ask John Is Different

Most real estate tools just show you a price estimate. Ask John uses **the most advanced AI on the market** to:

1. **Cross-reference every Belgian data source**: Statbel notarial transactions (actual sale prices, not asking prices), cadastre records, EPC/PEB energy registers, urban planning zones, noise maps, transport networks — across all 589 municipalities
2. **Provide transparent AI reasoning**: John doesn't just give a number. He explains *why* the price is what it is, what comparable properties sold for, and what premium features add or subtract value
3. **Adapt in real-time**: Tell John "the kitchen was renovated in 2023" or "there's a swimming pool" and the entire analysis (price, renovation budget, score) adjusts instantly
4. **Cover Belgium's unique complexity**: Three regions with different registration fees (12.5% Wallonia/Brussels, 3% Flanders first-time), different EPC requirements, different subsidy programs — all handled automatically

## What Ask John Analyzes

- **AI Price Estimation**: Cross-references Statbel notarial data (median price per m² by municipality), comparable properties, premium feature detection (pool, solar panels, architect-designed), area tier classification, and diminishing returns modeling
- **Acquisition Cost Calculator**: Registration fees by region, notary fees (degressive Belgian scale), mortgage registration, bank fees — everything calculated per your situation
- **AI Renovation Budget**: Itemized estimate per category (roof, kitchen, bathroom, insulation, heating, windows) with low/realistic/high scenarios calibrated to Belgian contractor rates
- **Mortgage Simulation**: Monthly payment, total loan cost, cash needed at signing — adjustable duration, rate, down payment
- **Neighborhood AI Analysis**: Livability score based on airport noise corridors (Zaventem, Charleroi), public transport proximity, schools, shops, green spaces
