Automating Deal Stacking: n8n + Airtable + Tally + APIs (Real Estate in 20 Minutes)

If you vet property deals by hand, this build will save you hours. In this live session I turn a real Upwork brief into a working deal-stacking automation using n8n, Airtable, Tally.so and APIs (Zillow/Rentometer equivalents; UK example uses PropertyData). You’ll see how to capture an address, trigger a webhook, fetch market/rent data, and prep a Google Sheets template for cash-on-cash and purchase-price adjustments. What you’ll learn Clarifying a client spec (“happy path”) before writing a line of automation Tally form → n8n webhook trigger (POST payloads done right) Structuring Airtable bases/tables + choosing predictable field keys Where Zillow/Rent APIs/PropertyData fit (and UK/US alternatives) Saving + processing results in Google Sheets for deal stacking Tools mentioned: n8n, Airtable, Tally.so, Google Sheets, Zapier/Make (comparisons), Zillow, Rentometer, PropertyData, Zoopla/Rightmove (context only).
