Frequently Asked Questions

Is RentLord a law firm?
No. RentLord is a technology platform. We provide tools, templates, and an AI trained on German rental law to help you understand your rights and manage your properties. We do not provide binding legal representation, but we can help you prepare the documentation a lawyer would need.
Can I use this instead of the Mieterschutzbund?
RentLord handles 90% of common rental issues: communication tracking, basic legal questions, deposit recovery templates, and issue logging. For severe cases requiring court representation, you should still consult a lawyer or the Mieterschutzbund, bringing your RentLord export as perfect evidence.
How does it help landlords?
It professionalizes your operations. By keeping all communication, documents, and maintenance requests in one centralized dashboard, you avoid disputes over "who said what when." It also streamlines distributing the annual Betriebskostenabrechnung.
Is the data secure and GDPR compliant?
Yes. All data is stored on servers within the EU, and we adhere to GDPR regulations. Sensitive documents are encrypted. We do not sell your data to third parties.
What languages does the AI support?
The AI Legal Concierge supports both German and English, and is trained specifically on German rental law (Mietrecht), including the BGB, local Mietspiegel, and relevant court precedents.
