BIIS

What BIIS does

BIIS (BIIS Bundesverband der Immobilien-Investment-Sachverständigen e.V. / GmbH) is a Frankfurt-based German professional association founded in April 2002 that aggregates independent, publicly-credentialed real estate investment appraisers into a curated network. As of the latest data, the association has 181 specialized member appraisers (up from 168 in 2024), whose combined valuation work covers more than €1 trillion of property annually across more than 40 countries, with approximately 50% of valuations performed for foreign properties due to cross-border investment flows. Membership is gated by rigorous criteria — a university degree, advanced postgraduate training, public appointment/sworn-expert status and/or RICS Chartered Surveyor credential, plus at least 7 years of investment property valuation experience — which positions BIIS as the leading credentialed body for institutional-grade real estate appraisal in Germany.

BIIS operates through two wholly-owned subsidiaries alongside the parent association (e.V.): BIIS GmbH runs the economic business operations (event organization, valuation management, and research data services), and BIIS IT Service GmbH handles the digital infrastructure. The core product surface consists of (1) BIIS Research 4.0 — a research database platform that aggregates member-submitted valuation data using the ZGIF Standard Bewertung (Subset 5.7) and integrates external market data from MSCI/Real Capital Analytics, Property Market Analysis (PMA), and IZ Research, delivered via a REST-API; (2) BIIS Valuation Services — managed engagement of member appraisers for institutional investors under a uniform fee schedule and valuation standards; (3) the annual BIIS conference (Jahrestagung); and (4) BIIS Market Talks, a recurring virtual webinar series covering asset classes including office, logistics, hotels, retail, residential, senior living, and data centers.

Revenue is generated through four streams: annual membership subscriptions from affiliated appraisers and valuation firms, professional services fees for valuation management routed via BIIS GmbH, conference and Market Talks event income, and research data services delivered on a data-for-data exchange basis to institutional investors who are regular clients of member firms. Pricing is not publicly disclosed; membership is qualification-based rather than tiered, and valuation engagements are quoted under a uniform fee schedule. The association holds recognized-partner status with German policymakers and industry bodies, is a member of ZIA, an information member of BVI, and a cooperation partner of ECORE (ESG Circle of Real Estate). BIIS is member-owned with no external shareholders or parent company, and no external funding rounds are disclosed.
