Problem

When workers in their mid-50s move to a Jeonse (lease deposit) arrangement after their children become independent, or maintain an existing Jeonse, there is no way to receive real-time alerts about changes to the landlord's mortgage settings or seizure/provisional seizure orders. Checking the property registry requires logging into the Internet Registry Office each time and paying a fee, and missing the timing of changes can mean losing a deposit worth hundreds of thousands of dollars. A significant portion of Jeonse fraud victims are people over 50 who failed to monitor registry changes after signing their lease.

Solution

Enter the Jeonse property address and registry ID number on the web to auto-detect registry changes (new mortgage registrations, seizures, ownership transfers) at regular intervals and receive alerts via KakaoTalk or SMS. Displays a risk score using a traffic-light system and provides an action guide on 'what steps to take' when changes occur.

Target: Ages 45-58, salaried workers or self-employed currently in or planning a Jeonse lease, with deposits of $150,000+
Revenue Model: Free monitoring for 1 property; additional properties at $2.15/month. Expert referral fees (judicial scrivener/attorney) when risk events occur.
Ecosystem Role: Infrastructure
MVP Estimate: 2_weeks
