The problem
Bank-auction properties are published bank by bank, and the listed price says little about what winning the auction will actually cost.
The constraint
Every listing links back to its official source, search works without JavaScript, and paid features fail closed whenever the payment state is uncertain.
The approach
Server-rendered search by state, city, type, auction mode and price; structured listing sheets with the official photos; a viability simulator whose cost models are versioned, so each saved simulation records the exact assumptions it used; email alerts and an external checkout.
The outcome
Live at arremataradar.com.br as a freemium product with anonymous, free and PRO tiers.
