## What the site does

1. A visitor picks a property type, enters address, facts and quality details.
2. The app returns an estimated market value with a low/high range and the
   drivers behind the number.
3. The visitor can continue to a "Selling tax & net proceeds" module that
   estimates Swiss property gains tax and what remains after a sale.
4. Optionally the visitor downloads a branded PDF report or books a free
   consultation with a Swiss real estate advisor.

No login is required for a valuation. Results are statistical estimates.

## Supported property types and inputs

- Apartment: living area, rooms, construction year, last renovation year,
  floor, condition, micro-location, balcony/terrace, energy class, parking.
- Single-family house: living area, rooms, construction year, renovation year,
  optional plot area, condition, micro-location, garden/outdoor, energy class,
  parking.
- Multi-family / apartment building: total rentable area, number of units,
  annual gross rental income, vacancy rate, construction and renovation year,
  condition, micro-location.
- Land / plot: plot area, zoning (building, mixed, agricultural), floor-area
  ratio (FAR), utilities connection status, micro-location.

Address entry auto-detects the city from a 4-digit Swiss ZIP code.

## How the valuation works

A hedonic (comparable-attribute) model, not a certified appraisal:

- Base rate: cantonal median CHF per m2, adjusted by a ZIP-level location
  factor and a property-type uplift (house and multi-family carry an uplift
  over the apartment baseline).
- Quality adjustments: size, effective age (renovation-aware), condition,
  floor level for apartments, micro-location quality, outdoor space and
  energy class each apply a multiplier.
- Extras: flat amounts for parking; a land premium where plot area exceeds
  the typical footprint for a house.
- Multi-family: blends the area-based value with an income-based value
  (gross rental income net of vacancy, capitalised at a cantonal gross yield).
- Land: plot rate model driven by zoning multiplier, floor-area ratio and
  utility connection status.
- Output: a point estimate plus a confidence range and a per-m2 benchmark.

## Selling tax & net proceeds

The module estimates Swiss property gains tax (Grundstückgewinnsteuer) and
builds a waterfall from sale price to net proceeds:

- Taxable gain = sale price − purchase price − value-adding investments −
  selling costs.
- Canton Zurich uses the exact progressive tier table.
- Other cantons use a simplified cantonal rate model.
- Holding period matters: short holding periods add a surcharge, long holding
  periods reduce the rate; replacement-purchase deferral is flagged where
  it may apply.
- Costs modelled: broker commission, notary and land registry fees,
  marketing costs.
- Waterfall: sale price → mortgage repayment → property gains tax →
  transaction costs → estimated net proceeds.

Inputs are validated (purchase year 1900–present, plausible purchase price,
investment and mortgage caps) so impossible scenarios are rejected.
