Industry

Property and real estate

Property technology deals in multi-year relationships between parties with genuinely different interests, mediated by documents, payments and statutory obligations. The system that keeps a continuous, attributable record is the one that resolves the dispute.

Workflows

The work that actually happens here

Named the way practitioners in this sector name them, because that is the vocabulary a delivery team has to learn before it can be useful.

Listing and viewing management
Publishing availability, scheduling viewings and capturing interest, across an agent’s own presence and portal feeds.
Application and referencing
Structured applications with identity verification, affordability evidence, employment and previous-landlord references.
Agreement and signature
Generating the agreement from the tenancy record, electronic signature, and storage with a signature audit trail.
Rent, deposits and arrears
Collection, deposit-scheme registration tracking, arrears schedules and reconciliation against the tenancy ledger.
Maintenance and works
Tenant-raised requests with evidence, triage, contractor assignment, access arrangements, completion and cost.
Compliance tracking
Safety certificates, licences and inspections tracked with escalating reminders ahead of expiry.

Constraints

What changes the architecture

These are the reasons a design that works elsewhere would be wrong here.

01

Multi-party access with genuinely divergent interests

Landlord, agent, tenant and contractor need different views of the same tenancy. A contractor needs the access details and not the arrears history.

02

Statutory deadlines carry penalties

Deposit registration and certificate renewal have legal deadlines with financial consequences for missing them. Reminders are a product requirement.

03

Records must be evidence-grade

Disputes are decided on the record. Timestamps, attribution and immutability matter more than convenience of editing.

04

Document-heavy workload

Load is dominated by document upload, generation and retrieval rather than concurrent browsing, which changes the architecture.

05

Identity evidence has a defined life

Right-to-rent and identity documents are held for a lawful basis with a defined retention period, after which they must actually be deleted.

Integrations

Systems we would expect to meet

  • Identity and right-to-rent verification providers
  • Deposit protection schemes
  • E-signature providers such as DocuSign or Adobe Sign
  • Payment providers and open banking for rent collection
  • Property portal feeds
  • Accounting systems for landlord statements

Trust considerations

What users and regulators need here

  • Tenants should be able to see exactly what has been requested of them and why, and what has been decided.
  • Contractor access must be tightly scoped and time-limited to the job.
  • Financial and identity data need permissions beyond ordinary tenancy membership.
  • Communications should be retained per tenancy so a dispute has a record.
  • Document retention must be implemented, not merely stated in a policy.

Architecture

A shape we would actually propose

A starting sketch, not a template. Discovery is what turns this into a specific design with recorded trade-offs.

Domain
The tenancy is the aggregate; properties, people, agreements, payments and works attach to it.
Access
Row-level security keyed on tenancy membership and role, with financial and identity data behind extra permissions.
Documents
Private storage, short-lived signed access, server-side validation, download auditing and per-class retention.
Ledger
Append-only tenancy ledger for rent, deposits and works costs, reconciled against provider settlements.
Reminders
Scheduled, durable compliance reminders with escalation and recorded acknowledgement.

Outcomes

What good looks like

  • A continuous, attributable record per tenancy that settles disputes
  • Compliance deadlines met through system reminders rather than individual memory
  • Faster application-to-agreement cycles through structured referencing
  • Maintenance resolution times visible and improvable
