Frequently Asked Questions About MietKlar

Short, direct answers to the questions landlords ask most often before getting started.

What is MietKlar?

MietKlar is an app for landlords that keeps rent payments, leases, documents, deadlines, and German utility cost statements (Nebenkostenabrechnung) in one structured place. It is available for iPhone and iPad on the App Store and for Android on Google Play.

Who is MietKlar for?

MietKlar suits private landlords with a single apartment as well as owners managing several buildings with many units. Properties, units, tenancies, and documents are organized hierarchically, so the app scales with a growing portfolio.

What does MietKlar cost?

The app itself is free. Creating properties, units, and tenancies, tracking rent payments, storing documents, and viewing a unit’s timeline are all available at no cost. Only the utility cost statement (Nebenkostenabrechnung) is a paid feature — it covers generating the statement and exporting it as a finished PDF.

Can I create a utility cost statement (Nebenkostenabrechnung) with MietKlar?

Yes. A step-by-step wizard guides you through cost items, distribution keys, and consumption figures. MietKlar calculates each unit’s share, offsets advance payments, and reports the balance as either a credit or an additional charge. The result can be exported as a finished PDF statement and sent straight to the tenant.

Does MietKlar handle the German Heating Cost Regulation (HeizKostenV)?

Yes. Statements account for consumption-based distribution of heating costs under HeizKostenV. The generated PDF includes everything needed for a transparent statement: billing period, unit, distribution key, area share, a full cost breakdown, advance payments, and the final balance.

How do I track open and overdue rent?

MietKlar creates the monthly rent entry for each unit automatically and flags it as open, due soon, overdue, or paid. The dashboard shows expected income for the current month, payments already received, open balances, and the number of overdue rents.

Where are leases and documents stored?

Documents are kept in a structured archive and linked to a property, unit, tenant, or lease. Categories such as contract, handover protocol, and invoice make them easy to find. Generated utility cost statements are saved to the document archive automatically.

What does the unit timeline show?

The timeline lists every event for a unit in chronological order: lease start, rent paid, rent overdue, documents uploaded, and lease end. It gives you the complete history of an apartment at a glance.

Which devices does MietKlar run on?

MietKlar runs on iPhone and iPad (App Store) and on Android phones and tablets (Google Play). Visiting mietklar.app/download opens the correct store automatically.

How is MietKlar better than a spreadsheet?

Unlike a spreadsheet, MietKlar generates monthly rent entries on its own, detects overdue payments automatically, links every document to the right unit, and produces the utility cost statement including a ready-to-send PDF. There is no manual tracking of deadlines, payments, or file folders.

Is MietKlar available in English?

Yes. The app is offered in German and English, and the generated utility cost statement PDF is bilingual (German / English), which helps when renting to international tenants.
