The one piece that holds everything together. On Keystone, that's verified data: who owns it, what condition it's in, and what it's honestly worth.
Every Keystone listing carries a verified title check and a FAULT condition rating before it goes live. No ghost listings, no stale prices.
A Keystone ID follows a property for its entire life, through every sale, renovation and owner. Buyers stop guessing. Sellers stop repeating themselves.
A permanent identifier tied to the erf, not the listing. It survives agents, portals and owners.
Foundation, Access, Utilities, Legal, Title. Five checks, one honest letter grade a buyer can read in a second.
Modelled from deeds transfers, municipal values and live market activity. Updated monthly, not on request.
List once on Keystone and your property distributes to partner portals automatically. No duplicate admin.
Buying or selling pulls in a dozen professionals. Keystone registers them, rates them on completed transactions, and puts them where the property is.
Keystone ships in stages. Each one earns revenue before the next one starts, and the architecture is built from day one to carry all of it.
Next.js and Postgres with row-level security. Phase 5 does not require a rebuild of phase 1.
The revenue foundation: a working property portal that people can list on and buy through today.
Every property gets its permanent Keystone ID and a Property Passport that follows it forever.
Proprietary valuation modelling and the FAULT condition rating become the reason people choose Keystone over a portal.
The property data layer. Suburb-level intelligence, transaction history and predictive market signals.
Everything a property transaction touches, running on one system, from first search to final transfer.
Keystone handles ownership records, identity documents and financial information. That is treated as a first-class engineering problem, not a policy page.
Explicit consent capture, purpose limitation, and a working data deletion path built into the schema.
A seller sees their listing. An agent sees their mandate. Permissions are enforced at the database, not the interface.
Title deeds, ID copies and compliance certificates stored encrypted at rest with signed, expiring access links.
Every view, edit and export of a property record is logged and attributable. Disputes get answered with evidence.
Listings clear title and identity checks before they appear. Unverified listings never reach a buyer.
Source code, database and customer records belong to Keystone. Export everything, any time, in open formats.
Listing is free. Verification takes about 48 hours. Your property keeps its Keystone ID for good.
