🩻 Listing X-Ray — paste any ad, see the truth

Paste the text of any ImmoScout/Immowelt/Kleinanzeigen listing. The same deterministic engine as the EziLens Wohnung extension runs right here: real costs, legality checks, scam patterns, physical traps, decoded broker language — entirely in your browser, nothing stored.

Step 1 — add the listing

Paste listing text or upload a PDF to prefill the fields — then review & confirm.

Helper calculators & knowledgeOptional — open when needed

True living area (WoFlV)

BGH: actual area >10% below contract → cut the rent and reclaim past overpayments.

Frozen-rent calculator (Kappungsgrenze)

Reserve stress-test (Peterssche Formel)

Peterssche Formel: a building needs ≈1.5× its construction cost in upkeep over 80 years. Rough rule, not a guarantee.

The knowledge the broker hopes you don't have

Educational self-help, not legal/financial advice. The analysis runs locally in your browser; nothing you paste is stored.
