Manage properties, without Excel chaos.
Every building, every unit, all master data in one place. With living areas, year of construction, energy performance certificate, photos and individual billing settings per property.
All your data, in one place
Master data, energy figures, contracts, photos — Rentprime keeps everything structured per property. No more Excel lists nobody can find when needed.
Address & construction type
Full address, build type, year built, energy class, energy certificate PDF — all directly at the property.
Residential units
Any number of units per property with m², rooms, location (ground/upper/attic floor). With Living Space Ordinance logic.
Energy source
Gas, oil, district heating, heat pump, pellets — important for the per-property CO₂ cost allocation calculation.
Annual consumption
Heating energy kWh/year for CO₂ tier classification. Entered once, updated annually.
German heating regulation split
50/60/70% consumption configurable per property. Because no house is like another.
Photos & documents
Up to 20 photos per property, energy certificate PDF, land register excerpts — all archived.
Every building is different. Your software needs to understand that too.
An older building in Munich needs a different heating-cost allocation than a new build in London. With Rentprime you configure German heating regulation split, energy source, annual consumption and billing options per property — without spinning up a separate software instance.
- German heating regulation split 50/60/70 % configurable per property
- Custom cost types per property (e.g. a lift in only one building)
- CO₂ tier model automatic by annual consumption
- Custom billing periods per property
From 1 unit to 500. Same software, same workflow.
Start small with your own freehold flat and scale up to an entire residential complex later — with no migration or upgrade path. The Pro plan already includes up to 25 units, the Portfolio plan includes 100 units (+€1.99 per additional unit).
- Property templates for new-build series (same build, multiple houses)
- Massen-Import via CSV (kommt in Q3 2026)
- Per-property notes and remarks
- Externe Anzeigen-IDs (Immoscout24, Immowelt, Kleinanzeigen — in Vorbereitung)
Before: 14 Excel files, one per house. Now: one click, all houses side by side, each with its own settings.
Property management software for landlords
Property management is the foundation of every professional letting operation. Anyone letting more than one or two flats soon outgrows Excel spreadsheets: the data is scattered across several files, updates get forgotten, and by the end of the year you've lost track of which flat has which heating-cost split. Specialised property-management software solves exactly this problem — all master data, energy figures, contractual relationships and photos are stored centrally for each property.
Particularly important for German landlords: the Heating Costs Ordinance (German heating regulation) requires correct splitting between consumption-based and area-based costs — typically 50, 60 or 70 percent consumption share. This split must be set per building and remain constant over the years. With Rentprime you set this once per property, and all subsequent bills automatically use the correct distribution.
The CO₂ Cost Allocation Act (CO₂ cost allocation), in force since January 2023, additionally requires classifying the building into one of ten CO₂ tiers based on annual consumption per square meter. This value is also captured once per property and then used annually — Rentprime automatically calculates the landlord and tenant shares per tier.
Practical tip: When creating a new property, immediately upload the energy certificate as PDF, all units with floor area per Living Space Ordinance, and annual consumption in kilowatt-hours. That way you have everything ready for the next bill and don't need to hunt for documents.
