Generate a Comparative Market Analysis
You can now get a CMA or Comparative Market Analysis of a home without any special software. You’ll upload listing and sales information by simply taking a Zillow listing screenshot and using an AI agent known as ChatGPT with a prompt to instantly receive a full CMA helping your make an offer on your ideal retirement home. Be sure to open homes like the one you’re looking at and enter all the parameters, and be sure to select “Sold” so you will pull up only sold homes. Sold prices will be the most reliable in determining true fair market value.
- Click the button below to open ChatGPT in a new tab.
- Upload your images (Screenshots of selected Zillow listing histories).
- Copy and paste this prompt into ChatGPT:
“Please extract data from these images of home listings and sales. I need a report with the average first listed price, the average number of days on market (from list date to sold date), and the average sold price.”
Open ChatGPT to Generate a Report
Tip: Try to upload images that show the list price, list date, sold price, and sold date as clearly as possible. You can simply copy a portion of the screen with the listing and sales data (screenshot). You can open up any listing in Zillow and scroll down to the listing history, and take a screenshot of that section from the listing date to the sold date. You can upload images like this on several or many homes that are similar to the one you want to make an offer on, and this will generate one of the sweetest little CMAs you could ask for, and it’s quite accurate.
This is an example of what a screenshot of the listing history in a Zillow listing. You upload this image in ChatGPT and as many other comparable homes’ listing history to the same query in ChatGPT, and below the images but before you hit the return to upload the images, include the prompt shown above.
