I built an extension for analyzing rental properties in Zillow
Hey everyone, I build a Chrome Extension for real estate investors to be able to easily calculate the cash flow of a rental property right within Zillow. As an aspiring real estate investor, I found spreadsheets and proprietary online calculators like Bigger Pockets to be complicated or slow. With Homescope, you can bring this within your workflow and estimate your operating expenses instantly.

Hey HN, I love scrolling through Zillow and spend way too much time thinking a property is gonna be my next home just to find a couple of days of research later what’s the catch. I built this property analyzer to get a quick overview of “the good, the bad, and the ugly” (love spaghetti westerns) for the property. In ~30-45s you get a pretty comprehensive analysis of the history, risks, and everything else about the property, on top of a short AI-generated podcast going over the details.
