ONE system for your entire real estate portfolio.
One that thinks ahead.
Whether you own properties or lease store locations: contracts, deadlines, service charges and payments in one place - instead of Excel lists and a dozen apps. Rentarion keeps every deadline in view and thinks the next steps ahead.
Who is Rentarion for?
Property managers, co-operatives & real estate companies
Property managers · Housing co-operatives · 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 and option deadlines from third-party commercial leases - calculated automatically with §573 BGB reference-date logic
- Every demand recalculated: service charge statements, index increases, turnover rent, direct debits - objection letter included
- Warned before automatic renewals and hidden special termination rights
- Rent optimisation radar: where you pay above market - and when the negotiation window opens
- Main and ancillary leases thought through together - with a reminder to also terminate storage and parking
- Portfolio comparison, store network map, bulk import & exports
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 and objection deadlines (§556 BGB), rent increases (§558 BGB), statutory reference dates (§573 BGB) - miss a deadline, lose the claim. Permanently. On both sides of the lease.
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 overstated index increase. 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.
What matters
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 - whether you issue statements or receive them. What you do with that is your decision - with four-eyes approval and a complete audit trail.
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.
15% reduction right looms
Heating or hot water costs not billed by actual consumption. The tenant can reduce those costs by 15% - caught before the bill goes out.
Objection deadline running
Your landlord's service charge statement is ten months old. After twelve months objections are barred - the deadline sits as a task in the cockpit, the objection letter is prepared.
Index increase overstated
The increase letter was recalculated against the official CPI series: overstated by €74 per month. Objection letter in one click - or one-click adoption if everything checks out.
Commercial default applies
No termination period agreed in the commercial lease - the statutory default applies (6 months to quarter end). Rentarion calculates the termination window automatically.
The scope
Two perspectives, one system
Both tracks share contract data, the deadline engine and the permission system - the modules on top are cut for the job at hand.

- Rent optimisation radar with negotiation window
- Portfolio comparison, store network map, bulk import
Control & accountability
Your data belongs to you - every change stays traceable.
Four-eyes approvals
Critical changes - deadlines, rents, deposits - are released by a second pair of eyes before they take effect. The decision stays with you, documented in the system.
Complete audit trail
Every contract data change, every approval, every magic-link click is logged and fully traceable.
Roles & Permissions
Five roles from viewer to super-admin. Granular access control, strict tenant isolation at query and storage level.
EU hosting & GDPR

Data processing - EU data centres only, DPA under Art. 28 GDPR
Database, file storage, OCR, AI field extraction, email delivery and backups all run in EU data centres - the encrypted off-site backups in Germany.
