No more spreadsheets and folders to cross-check. - Rents and charges per property - Tenants and co-owners on each lease - Several portfolios, each with its own members ### Never miss an indexation, never miscalculate one Each lease anniversary becomes a task. The new rent is calculated from the official index of the property’s country — the health index published by Statbel in Belgium — with every figure shown, and the letter to your tenant is generated for you. - Upcoming, due, calculated, sent, applied: you always know where you are - The formula and the index values behind every amount - The rent history kept on the lease - Other countries too: Belgium’s monthly health index, the French IRL, Dutch, German, Italian and Spanish rules ### Lease contracts from your own template Write your template once, with fields for the parties, the property and the rent. Each lease then produces its contract as a PDF, filled in and ready to sign. - Your wording, your clauses - Filled from the lease, the tenants and the property - An example template to adapt — not legal advice ### Everything you know about each property Energy certificate, meters, surface, cadastral income, purchase price and estimated value: the facts you look for at the worst moment, kept with the property. - EPC rating and expiry date - Purchase price against estimated value - Contractors and advisers linked to the property ### Documents filed, expiries tracked Leases, inventories, certificates, insurance and invoices are filed against the right property or lease. Expiry dates turn into reminders before they become problems. - Reminders for indexations, lease ends and certificates - Your own reminders for maintenance - Nothing lost in a mailbox ### Publish a vacant property in one click A vacant property gets its own public page, in six languages, found by search engines and AI assistants — and enquiries arrive straight to you, without an agency. - A public page per property, in English, French, Dutch, German, Spanish and Italian - Hide the exact address if you prefer - Enquiries by e-mail, directly to you ## Pricing Prices per portfolio, VAT excluded.

Private landlords and small portfolios, whether you rent out one flat or a few houses, alone or with co-owners. The app speaks French, Dutch, English, German, Spanish and Italian, and indexes rents by the rules of each property’s country. ### How is the indexation calculated? With the health index published by Statbel and the formula of the lease’s region. Every amount comes with the index values and the formula used, so you can check it before sending anything. Properties outside Belgium follow their own country’s rules: the IRL in France, the CPI in the Netherlands and Germany, ISTAT in Italy, the IPC capped by the IRAV in Spain. ### Is the contract template legal advice? No. It is a document tool: the shipped template is an example to adapt, and you remain responsible for the contracts you use. ### Can several people work on the same portfolio? Yes. With Premium you invite co-owners, an accountant or a manager, each with a role: read only, edit, or manage. ### Which languages? The application and the e-mails speak French, Dutch, English, German, Spanish and Italian, and example contract templates exist in each of them. The public site is in all six languages too; the legal documents are in French, Dutch and English. ### What if I stop? Nothing is deleted. Your portfolio becomes read-only: you can still read everything and pick up again by subscribing. ## Help centre Full text of every article: https://www.stoffrent.com/llms-full.txt - [Getting started](https://www.stoffrent.com/en/help/getting-started): Create your portfolio, add a first property and lease, or look around with sample data. - [Properties, photos and documents](https://www.stoffrent.com/en/help/properties): Record each property once, with its energy certificate, photos and documents. - [Tenants, landlords and leases](https://www.stoffrent.com/en/help/leases): Who rents what, for how much, from when - the basis of indexation and reminders. - [Rent indexation](https://www.stoffrent.com/en/help/indexation): How StoffRent calculates the indexed rent, and the steps from “due” to “applied”. - [Contract templates](https://www.stoffrent.com/en/help/contract-templates): Generate lease contracts from your own templates or from the example ones. - [Reminders and alerts](https://www.stoffrent.com/en/help/reminders): What StoffRent reminds you about on its own, and the reminders you add yourself. - [Publishing a listing](https://www.stoffrent.com/en/help/listings): Put a property for rent or for sale on the public site, with the details you choose. - [Members and security](https://www.stoffrent.com/en/help/team): Share a portfolio with a co-owner, an accountant or a manager, and protect the account. - [Trial, plans and invoices](https://www.stoffrent.com/en/help/billing): What the free trial includes, how the plans differ, and how to cancel. - [Your data: export and deletion](https://www.stoffrent.com/en/help/your-data): Take all your data with you, delete a portfolio or close your account. ## Legal - [Terms of service](https://www.stoffrent.com/en/terms) - [Privacy policy](https://www.stoffrent.com/en/privacy) - [Data processing agreement](https://www.stoffrent.com/en/data-processing) - [Changelog](https://www.stoffrent.com/en/changelog) - [Service status](https://www.stoffrent.com/en/status) ## Free rent-indexation calculator Works out an indexed rent from the official index, for free and without an account: https://www.stoffrent.com/fr/indexation-loyer, https://www.stoffrent.com/nl/huurindexatie, https://www.stoffrent.com/en/rent-indexation, https://www.stoffrent.com/de/mietindexierung, https://www.stoffrent.com/es/actualizacion-alquiler, https://www.stoffrent.com/it/indicizzazione-affitto ### Rent indexation in Belgium Calculator: https://www.stoffrent.com/en/rent-indexation/belgium.
