See the real cost of any Austrian property in seconds — directly on the listing page.

Buying an apartment in Austria usually means opening Excel for every listing. Taxes, fees, mortgage, heating — all calculated manually.

METROX Lens removes that step. It shows the full financial picture instantly — without leaving the listing.

🚀 Beta 0.5 — available now. Manual install via .zip (Chrome Web Store approval in progress). Works directly on the two largest Austrian portals: Willhaben and ImmoScout24. To the product page →

What you see instantly

🏷️ Total buyer costs

Full breakdown of every line item:

  • Grunderwerbsteuer (3.5%, § 7 GrEStG)
  • Land registry (1.1%, § 26 GGG)
  • Notary / contract drafting
  • Broker commission (per IMV)
  • Mortgage lien (1.2% on loan)

→ No lookup. No assumptions.

💡 Save up to €8,000 instantly

One toggle applies the Hauptwohnsitz exemption (BGBl I 110/2023, valid until 30 June 2026). On a typical €400k–€500k apartment, the savings appear immediately.

💰 Monthly mortgage payment

Adjust down payment, rate and term — see the monthly cost live. Built-in FMA checks (LTV, DSTI, term) flag risky setups inline.
