The decision layer for Dutch housing — Rental and Sale, lawful in every step.
Tenon decides who qualifies — a household for a rental home, a buyer at a bid — runs the procedure the law requires, from the published criteria to the award or the transfer, and publishes a record anyone can verify. Both rails run on rules cited to Dutch law, so compliance isn't a module you add. It's how every part works.
Release 1.1.0. A stable core, tested on a synthetic estate and ready for its first integration.
Lawful in every step
Tacit decides by the law.Two rulebooks — 92 Rental rules and 77 Sale rules — each rule citing its source.
Ravel runs by the law.The Rental procedure the Wet goed verhuurderschap requires, and the Sale from the offer to the transfer at the notary — every decision a person's act, recorded as it was reached.
RESOnance lets anyone check it.Rental and Sale listings on the RESO standard, and a public record a regulator or municipality can verify without asking anyone for access.
The two rails, end to end.Who decides, who signs and who holds which key, step by step — for a rental and for a sale.
