Guide — Germany

Operational checklist

A good rental file in Germany starts with clean property data, a clear lease record, rent tracking, deposit evidence, payment history and documents stored in one place.

Country pack

Country-specific features are activated only for the property jurisdiction. Changing the interface language never changes the country pack or the rules applied to the property.

Documents

• Mietspiegel / local rent reference where relevant
• Nebenkosten and annual service-charge evidence
• Kaution and handover protocol
• Energieausweis and municipality-specific records

2026 market benchmark

The local software market mixes free tools, portfolio subscriptions and per-unit pricing. Isulab is positioned for independent landlords who want a low entry price without mixing the rules of another country.
