Real Estate
Find, enrich, and rank real estate markets
In this example, we built an app that uses Nimble to search the web for live market statistics, Zillow listings, and Perplexity market reports, then has Claude rank the top investment markets.
Quick Start
Inputs
- City List The US cities to collect market data for — 100 cities are included by default and can be edited in the config file before running.
Outputs
- Ranked city scorecard with investment scores across 5 dimensions
- Top investment markets selected and ranked
- Per-city investment thesis and key risk
- Active Zillow listings across tracked markets, with photos and full specs
- In-depth city report per tracked market
- Interactive US map with cities sized by transaction volume and colored by investment score
How it works
A 4-phase pipeline. Read the blog here for a deeper explanation.
- Collect The Redfin Extract Template pulls live market stats for 100 US cities — median price, days on market, sale-to-list ratio, YoY appreciation, homes sold, and price per sqft.
- Rank Claude scores all 100 cities on 5 investment factors and selects the top 10, with a written thesis and key risk per city.
- Listings The Zillow Extract Template pulls active listings across 3 zip codes per selected city — 30 Extract Template calls, 1,199 total listings with photos and full specs.
- Research The Perplexity Extract Template generates a deep market report for each of the 10 cities, covering appreciation trends, affordability, rental demand, and risk factors.
