Hometwin brings housing information together in a single digital dossier. Secure, complete and always up-to-date. Residents gain control over their homes, while municipalities, mortgage providers and energy companies collaborate on a transparent sustainability approach. From maintenance and energy performance to subsidies and WOZ (property valuation) data: Hometwin makes housing data accessible and usable.
The building blocks of an effective property dossier
- Digital hub: one place for maintenance, energy, subsidies and value.
- Always up-to-date: automatic link with public databases such as BAG and WOZ (NL).
- Collaborate with confidence: easily share data with advisors, contractors or family.
- Safe & European-proof: ISO 27001-certified, GDPR-by-design and compliant with EU standards.
- Sponsorship model: municipalities, banks and energy companies offer residents a free account.
