Property Track

Property Track is a browser extension for Rightmove, the UK's largest property platform that hosts ~90% of all listings across England, Scotland, and Wales.

The project began with my own house search experience, where I found myself frustrated with the lack of transparency on the pricing of listings.

So I built a solution that keeps track of asking price changes. The extension injects this data into Rightmove pages as a user browses for properties.

London Map

My property search concentrated on central London apartments and was a painful experience due to potentially high service charges, ground rent, and often limited living space.

Rightmove's basic filters forced me to open each listing to check if it met my criteria. When I asked Reddit about their struggles, they shared similar problems with tenure types and auction listings.

So I added a London map to the Property Track website that extends these filters. It adds options for service charge, ground rent, floor size and tenure, while eliminating auction properties.

The prototype displays results in a map view with additional information such as price per square foot, parking and whether a garden exists without the user having to open each listing.

Rightmove has since responded to these complaints and added some of these filters.

AI Search

Building on the London site, I added an AI search as an experiment with natural language processing. Users can type queries like "2 bed flat in Bermondsey less than 750k" and get matching listings back, without having to think about filters or syntax.

The feature was a chance to explore how far a language model could replace a traditional search UI, and to ship something end to end using Claude Code.

Plus

I assumed the data was the most valuable part of Property Track. But when I spoke to potential acquirers, every conversation went straight to the user base.

No deal was made, but it changed how I saw the project. If an engaged user base is what people value, it makes sense to build on it. So I added Plus, an optional subscription that helps a buyer judge whether a home is fairly priced, right on the listing.

It adds three tabs beside the price history. Comparables shows similar homes for sale or to rent nearby. Recent sales shows what homes nearby actually sold for, from HM Land Registry. Trends shows sold prices and the number of sales in the area over time. Price history stays free.

Since October 2023, Property Track has tracked over 9m listings and 4m price changes. It has over 2,000 monthly active users.
