A Zilculator alternative for fast on-listing screening
Zilculator is a property analysis and marketing platform aimed at agents, wholesalers and investors who need to produce polished, branded reports. It automates data entry by pulling property information from listing sources and rent data providers, then generates professional analysis reports you can send to clients or buyers.
Mortar is narrower on purpose: it answers "is this listing worth my time?" while you are still on the listing. It reads the Zillow page you have open, applies deterministic formulas with real per-state property tax and insurance, and gives you the four numbers and a verdict in seconds. No report generation, no context switch.
