Problem

Tenants preparing for a Jeonse (lease deposit) contract need to individually verify 6-8 documents including property registry, building ledger, landlord tax delinquency status, and local market prices, which takes 3-5 hours. Non-experts miss critical risk signals such as mortgage-to-value ratios and multi-household tenant verification, exposing them to deposit losses averaging $37,500-$150,000 (5,000만-2억원).

Solution

By simply entering an address, the system automatically collects property registry, building ledger, actual transaction prices, and landlord delinquency history, then instantly calculates a Jeonse fraud risk grade from A to F. It visualizes key risk factors including mortgage ratio, market value relative to multi-unit tenant count, and number of properties owned by the landlord, and provides recommended follow-up actions when risks are detected.

Target: Single-person households and newlyweds in their 20s-30s preparing Jeonse (lease deposit) contracts, and licensed real estate agents
Revenue Model: Per Transaction billing at $7.50 (9,900원) per single diagnosis, Monthly Subscription plan at $22/month (29,000원) for unlimited diagnoses (targeted at real estate agents)
