Integrated Rent Indexation
With SNDQ's automatic rent indexation you never miss a raise. Easily manage revisions, send reminders with templates, and always stay informed about indexation possibilities.
In Belgium, rent is adjusted annually based on the health index, as stipulated in the lease contract. For landlords and estate agents with multiple properties, manually calculating and tracking each indexation is time-consuming and error-prone. SNDQ automates this entire process: the system calculates the correct indexation on the anniversary of each lease, alerts you when an increase is possible and automatically generates the corresponding communication to tenants. For revisions or changes to the contract, SNDQ adjusts all payment data immediately. You can send reminders via personalised templates, so tenants are informed in time. This way you never miss an indexation opportunity, stay legally compliant and maximise your rental income without additional administrative work.
