Data transparency

1) Source classes

• Official statistics and public authority sources
• Municipal or regional open-data portals
• User-provided property and document data
• Technically extracted document fields from searchable files (verify-before-use suggestions only)

2) Update cadence and freshness

Published indicators should carry a date or “as-of” window where possible. Sources without a timestamp are assessed conservatively.

Different sources refresh at different speeds (monthly, quarterly, ad hoc). There is no uniform real-time guarantee.

Plan boundaries are also enforced technically (for example Free scenario-attempt limits and gated workflow depth).

3) Confidence logic (high / medium / low)

High ; Source is clear, dated, methodologically traceable, and current.

Medium ; Source is plausible but has partial uncertainty (e.g. interpolation, partly older reference dates).

Low ; Limited coverage, unclear methodology, or a strongly outdated time reference.

4) Methodological limits

Immowiser produces deterministic model indications. Outputs remain dependent on inputs, data quality, market dynamics, and legal changes.

Optional AI-assisted hints (when enabled) never replace deterministic checks or your verification duties.

The platform does not replace individual legal, tax, financial, or investment advice.
