Show HN: I scraped 30M+ UK property records using LLM to fix a problem

If you’ve ever tried buying or investing in property in the UK, you already know how broken the process can feel. As a property investor myself, I know how frustrating and fragmented it is, jumping between outdated spreadsheets, buried planning application records, 10+ open tabs, and half-complete portal listings, confusing price trends… and even then, you’re still left guessing.

That’s exactly why I built HomePortfolio; a tool designed to cut through the noise and give everyday homebuyers and investors instant clarity and confidence.

I built an AI automated scraper that pulls live listings from 50+ sources, merges them with sold-price data from HM Land Registry, ONS neighbourhood stats, school stats, EPC ratings, and even flood-risk and planning data from local councils.

Then I ran it all through LLMs to extract everything you’d normally spend hours digging for: investment opportunities, valuations, price trends, beds/baths, floor area, energy score, crime rates, school proximity, flood zones, planning alerts, rental yields you name it.

The idea is simple: show a unified, data-rich view of any UK property in seconds, so no one has to rely on guesswork, scattered sources, or gut feel anymore.

Pro tips Flexible locations: query by address, city, or county Auto-extracted specs: “3 bed semi-detached, 1 bath, 1 200 ft²” parsed straight from descriptions Risk flags: instant alerts for flood-risk zones and high-noise areas Yield estimates: 5-year rental & capital growth forecasts from sold-price trends Neighbourhood snapshot: Demographics, crime, school quality, walkscore, air quality all in one view

It’s still early days but would love thoughts or feedback from this community on data quality, UX improvements, or new feature ideas. Especially curious if you’ve run into the same pain points and what else you'd want to see built.

This is very impressive, I tested a few addresses and the data is much more than I would get from Home Track (the data company behind Zoopla).

For school rating, I noticed you have "Don't Know" for private schools. Zoopla and Rightmove label them as Independent.

Are you planning to offer the data via API?

Thanks Oras for your kind words. Yes, you are right, I'm currently pulling data from only public schools at the moment. Independence schools is part of our future roadmap. I've used Home track, Realyse and Spectre data and I constantly found them somehow incomplete, the reason I built this. Data via API is part of our delivery roadmap I'm currently building and MVP should be available by end of 2nd quarter this year.
