PaTMa Property Insights is a Firefox browser extension designed to improve the property searching experience by providing users with comprehensive price history and investment metrics. It allows access to historical pricing data from major property portals like Rightmove, Zoopla, OnTheMarket, PropertyNews, and PropertyPal, enabling users to make informed decisions while negotiating property prices. Users can create a free PaTMa account to unlock essential features, including yield, ROI, and rent estimates directly within their browser as they explore various listings.

In addition to price histories, the extension offers property comparables for both sales and rentals, along with extended data through its PaTMa Prospector feature. While basic information is available for free, advanced features such as detailed property addresses require a subscription. The user interface is designed for easy access, with a dedicated icon in the browser bar to view all available property data seamlessly.
