Vermieter1.de

Vermieter1.de helps private landlords run rentals. Its core flows are creating the Nebenkostenabrechnung step by step, recording costs, allocating them to tenants and exporting a PDF, plus heating cost statements, and a digital Wohnungsuebergabe where rooms, photos, meter readings, keys and signatures stay together in one handover protocol that can be prepared for use without a network. Tenant management, a payment overview with connected bank accounts, deposit management and a tenant portal round out the daily work.

Further modules include property and WEG management, an applicant manager, a document generator, meter readings and consumption, energy contracts, tasks, tax preparation, a financial overview and an AI legal check. Free tools and calculators cover rent price comparison, index and graduated rent, cap limits for rent increases, notice periods, a landlord confirmation form, a tenant self-disclosure form and a check of utility statements.

The service says data is stored encrypted in Germany and works in the browser without installation, with a live demo that needs no login. The first apartment is free permanently with no time limit, with paid plans for more units.
