Renting a home. The Ken Case Competition 2026, Round 2. The left column is the happy flow; the red cards beside a state are what happens when that step goes wrong.
Tenant does a five-minute voice intake in their language: budget, area, office or school location, must-haves. Owner lists the flat by voice and uploads a walkthrough video or 360 view.
Agent verifies the listing address, then ranks flats by percentage match, including real commute time to the tenant's office or child's school.
Agent relays the tenant's questions. The owner answers once, and that answer is reused for every other enquirer.
A slot is agreed from both calendars, with a reminder to both sides the evening before.
Agent proposes rent and terms inside the range the tenant set.
Tenant says yes, then owner says yesThe agreement is drafted with a Promise Ledger: every verbal promise becomes a dated line, such as "fix bathroom tap by 15 Oct".
Both signTenant authorises a rent mandate once. The deposit is blocked in the tenant's own account, not transferred to the owner.
Tenant authorises once, in their own UPI appA joint, timestamped condition record of every room becomes the baseline for the deposit at exit.
Both confirm the recordRent is collected on the agreed date. Electricity and other bills are fetched and split with roommates. Any problem the tenant raises goes to S9.
Tenant reports once. Agent notifies the owner, captures the date the owner commits to, and checks when it passes. Closed when the tenant confirms it is fixed, then logged to the property's history.
S8 and S9 repeat for the length of the tenancy. The tenant never has to send the second message.
Sixty days before the end date, the agent compiles the tenancy's own record: on-time months, issues closed, local rents. It sends a proposal built from that record.
Both approveAgent drafts and sends the notice, compares the move-out record against move-in, and proposes deductions. The deposit is released and feedback is added to the property's history.
Both approve the deductionsS4, S5, S6, S7, S10, S11, and any repair spend above the cap the owner set. Everything else the agent does on its own, which puts it at L3: it acts inside limits people set, and people handle whatever falls outside them.
