Description

How It Works
This workflow automates end-to-end real estate investment analysis by aggregating data from multiple sources and applying AI-driven evaluation. It is designed for real estate investors, analysts, and portfolio managers seeking data-backed decisions without manual research overhead. The solution addresses the time-consuming challenge of collecting and analyzing fragmented real estate data—such as MLS listings, public records, demographic trends, and macroeconomic indicators—and transforms it into actionable insights using AI. Data is collected in parallel across four streams: MLS property data, public records, demographic information, and macroeconomic signals. These streams are consolidated into a unified dataset and processed by OpenAI GPT-4, using calculator tools and structured output parsing for quantitative analysis.
