Indexpilot
A jurisdiction-pinned rent-indexation workspace that combines official index observations, lease facts, rule versions and qualified approval into traceable increase proposals.
Property agencies managing many leases may repeatedly retrieve official indices, apply regional rules, calculate proposed increases and prepare notices. Indexpilot proposes a maintained jurisdiction pack that joins official observations with lease-specific facts and an approval trail. The supplied research confirms a machine-readable Belgian health-index dataset and an early open-source implementation of the Belgian formula with regional and energy-performance variations. It also confirms a member calculator, a consumer calculator and a property-management platform with indexation features. The category is therefore active; the plausible gap is a multi-lease, agency-oriented review and evidence workflow.
A formula is not a legal entitlement to increase rent. Region, lease type, execution and start dates, anniversary, base rent, base and new index, energy-performance status, caps, freezes, rounding, notice timing and contractual wording can all change applicability. An official data value still needs series identity, publication date, revision state and effective rule context. The supplied open-source core carries a reciprocal license that requires a pre-build compatibility review; copying or integrating it cannot be assumed. A generated notice is a draft, a signature proves bounded origin and integrity, delivery is not receipt, and neither creates legal validity.
Official source, retrieved observation, rule source, rule version, lease assertion, document evidence, eligibility hypothesis, calculation, exception, qualified finding, owner approval, notice draft, signed artifact, delivery attempt, provider acknowledgment, recipient receipt, rent-ledger update, dispute and realized collection remain separate. The first release should cover one Belgian region with current primary authority and historical replay before considering other regions or countries.
A property-management agency operations or compliance lead responsible for recurring rent-index reviews across multiple landlords and leases in one jurisdiction.
A maintained jurisdiction pack and deterministic calculation engine can serve many leases once authority and ingestion are established.
Confirmed open data, active tools and changing regional rules support a current workflow need without a hard universal deadline.
Two cross-references and no inbound links leave convergence limited despite a coherent vertical workflow.
The input names an agency workflow, confirms an official machine-readable index source, exposes real regional complexity and identifies active but differently packaged alternatives.
Only a Belgian starting point is well evidenced, legal applicability requires current qualified review, active competitors reduce novelty, and the referenced open-source license creates a build gate.
