Three rooms, 85 square meters. Fits a family of three easily.
Caller 100:55
Great. And the kitchen is included, right?
Nimmi AI01:02

Nice. What about the deposit? Can I pay in installments?

Yes, per BGB §551 you can split the deposit into 3 monthly payments. That's your right. Just general info, not legal advice.

I follow German rental law by design. Not by choice.
As an AI leasing assistant, anti-discrimination rules, data protection, and tenancy law are part of my architecture. I can't break them even if someone asks me to.
I only ask what the law allows
Household size, income, move-in date, pets, WBS status. That's my list. I never ask about anything else.
I ask for consent before I start
Every call begins with a GDPR consent notice. If someone says no, I offer to connect them with you. Their data is stored in Frankfurt and deleted automatically.
You make the final decision
I qualify and recommend. Every result goes to your dashboard. I never approve or reject anyone on my own.
I qualify and recommend. Every result goes to your dashboard. You as the property owner always have the final say.
Things I will never ask about
These are not guidelines. They are hardcoded into how I work. I physically cannot ask these questions.
End to end encrypted. Full call recording and transcript available in your dashboard.
From the rental inquiry to the booked viewing. I handle the conversation.
I answer apartment questions
Cold rent, warm rent, floor plan, balcony, cellar, parking. If it's in your listing or notes, I know it.
I explain rental conditions
Deposit amount, notice period, house rules, pet policy. General information, clearly explained.
I confirm attendance
Before every viewing, I call to make sure the applicant is still coming. If they cancel, I offer the slot to someone else.
You set the criteria. I qualify every rental applicant.
During setup, you tell me what matters for your apartment. When you rent out your apartment, I check every applicant against your criteria during the call as your AI leasing assistant. No exceptions, no shortcuts.
Typical examples
Every applicant gets the same check. Every decision follows the same rules.
From the moment someone applies until the viewing is booked.
I call every applicant who leaves a phone number. Usually within seconds.
I explain your apartment clearly so they understand what they're applying for.
I check whether they meet your criteria.
I answer their questions about the apartment and rental conditions.
I offer available viewing times and book the appointment right away.
I send a confirmation and reminder before the viewing.
If they don't answer, I try again later.
If they call back, I pick up where we left off. I remember everything.

Nimmi AI screens, qualifies, and schedules.
