Analyze real estate deals using Google Sheets, Groq AI, and Gmail

Real Estate Deal Analyzer using Google Sheets, AI (Groq) and Gmail

This workflow automates real estate investment analysis using Google Sheets and AI. It calculates ROI and rental yield, detects duplicate entries, generates AI-based recommendations and sends email reports. Simply connect your Google Sheets, Groq (AI) and Gmail accounts, then start adding property data.

Quick Implementation Steps

Login to your n8n account. Connect your Google Sheets account (input + history sheets) Add Groq API credentials for AI analysis Connect Gmail for sending notifications Add property data (price, rent, expenses) in the sheet Run the workflow manually or activate it

What It Does

This workflow helps you analyze real estate investment opportunities automatically. Whenever a new property entry is added to your Google Sheet, it calculates important financial metrics such as annual rent, profit, rental yield and ROI.

It then checks whether the property already exists in your historical records. If it finds a duplicate, it stops further processing, marks the entry and sends a notification email.

For unique entries, the workflow uses AI to evaluate the investment and classify it as BUY, HOLD or AVOID, along with risk level, reasoning and improvement suggestions. Finally, it stores the result, sends a detailed email report and marks the row as processed.
