Who is Rentarion for?
Property managers & real estate companies
Property managers · Real estate companies · Asset managers · Family offices
- Utility billing deadlines §556 BGB calculated automatically from the billing period
- Rent increase potential §558 BGB checked against blocking period + cap limit
- Utility cost allocation per BetrKV (all 17 categories, incl. heating hybrid)
- Heating Costs Regulation compliance: 15% reduction risk caught before billing
- Rent collection from the bank statement: target/actual matching, arrears early warning, owner statements
- Owner module, deposits §551, vacancy & turnover, DATEV export
A missed utility billing deadline (§556 BGB) means the claim for back-payment is lost for good. Rentarion flags every deadline months in advance — across the whole portfolio.
Chain operators & multi-location businesses
Bakery chains · Grocery & retail · Restaurant groups · Hotel groups
- Termination dates per §573 BGB calculated automatically with reference-date logic
- Indexed rent adjustments recognized before they hit your invoice

- Portfolio comparison with remaining-term heatmap, €/m², risk level

A single overlooked renewal clause often means five more years of commitment and a six-figure sum. Rentarion pulls exactly these deadlines from every contract — and reminds you in time.

The Problem
What happens without Rentarion
Contracts in folders, deadlines in Excel, clauses unchecked — costing you real money and your overview every single day.
Deadlines are missed
Termination deadlines expire unnoticed. A single missed deadline can trigger automatic lease extensions of 3–5 years — tens of thousands of euros that could be avoided.
Contracts without structure
Notice periods, index clauses, deposits — all buried in PDFs. Every inquiry takes hours of manual searching — time your team should spend on strategic work.
Legal deadlines overlooked
Utility billing deadlines (§556 BGB), rent increase periods (§558 BGB), statutory reference dates (§573 BGB) — miss a deadline, lose the claim. Permanently.
Automatic deadline watchdog
Termination, utility billing, index adjustment, stepped rent, renewal — and many more: identified automatically, with reminders 6 months, 3 months and 1 month ahead by email. No deadline will ever be missed again.
All key data in under a minute
Upload a contract — start date, notice period, rent, deposit, index clause: structured and verified against the source document. GDPR-compliant in the EU.
Warned early, before it gets expensive
Rentarion keeps statutory deadlines and critical clauses in view (BGB, BetrKV, Heating Costs Regulation) and flags them early — a §556 deadline, an invalid clause or an index adjustment. You decide what to do.
How it works
From PDF to overview — in under one minute
Upload contract
Single or bulk upload, drag & drop. Or CSV import when you migrate existing portfolios.
Automatically structured
Rentarion reads your leases and structures all key data — every field checked against the original document. Processing exclusively in the EU.
Engine review & reminders
Deadlines calculated per BGB, critical clauses checked, four-eyes approval. Email reminders and weekly digest.
Thinking ahead, not just managing
Rentarion flags issues early — before a deadline or clause gets expensive.
Rentarion keeps statutory deadlines and critical clauses in view (BGB, BetrKV, Heating Costs Regulation) and warns you early. What you do with that is your decision — with four-eyes approval and a complete audit trail.
Clause invalid
Residential termination clause to tenant's disadvantage detected — the statutory 3-month period applies, your correspondence must not rely on the contract text.
Billing deadline in 89 days
Your billing obligation expires in 89 days. Miss this deadline and you lose the claim to any back-payment — permanently.
Rent increase possible
15-month blocking period ends March 2027. Cap limit (20% over 3 years) automatically checked. Ready to send the rent increase notice.
Mixed clause invalid
Stepped rent and index-linked rent agreed simultaneously — invalid in residential leases. Four-eyes review triggered before a wrong demand is sent.
15% reduction right
Heating or hot water costs not billed by actual consumption. Tenant can reduce costs by 15% — caught before the bill goes out.
Commercial default applies
No termination period agreed in the commercial lease — statutory default applies (6 months to quarter end). Calculated automatically.
From a property manager's day-to-day
One system for every step — made visible.
From daily steering to the on-site handover to the owner report — shown in the landlord portfolio. The modules that turn scattered tools into one platform.
Daily cockpit
"What needs doing today?" — Rentarion answers it for you.
Instead of a dozen lists in your head: a cockpit that prioritises the day's tasks every morning — billing deadlines, terminations, rent increases, follow-ups. Done, later, dismissed — in one click.
- Every task sorted by urgency — from billing deadline to follow-up
- 1-click actions straight from the task
- Portfolio status at a glance
On site, digital
The apartment handover — entirely on the iPad.
Meter readings with photo, defects with proof photo, digital signature — and a finished handover report as PDF at the end, sent by email. No paper, no re-entry back at the office.
- Meters & defects documented with mandatory photo
- Digital signature with timestamp
- Auto-generated PDF report — sent instantly
End-to-end process
Tenant turnover — from notice to re-letting, seamlessly.
When a notice arrives, Rentarion starts the guided process: handover, deposit settlement, marketing, new lease. Every phase ticked off, nothing forgotten, all documented.
- 6 phases with progress tracking
- Handover & deposit settlement directly linked
- Every step in the audit trail

Letters & correspondence
From the billing cover letter to the rent increase — pre-drafted.

- Templates for billing, rent increase, termination, deposit, reminder — and more
- Mail merge across many units

Rent collection in view
Who has paid, who is in arrears? The bank statement answers it.
You import the bank statement file from your online banking — every bank supports camt.053 or CSV. Rentarion matches the payments to your leases, compares target vs. actual and warns early on arrears, before they turn into lost rent.
- Automatic payment matching, confirmed instead of guessed
- Target/actual matrix per lease and month
- Arrears early warning right in the daily cockpit
Running leased locations — not managing buildings?
For tenant portfolios Rentarion shows the other side: deadlines from third-party commercial leases, portfolio comparison across all locations, a rent optimisation radar.
