AI-powered property intelligence

Know what you’re buying before you spend a penny

Tetsoma scans listed property data and flags risks in plain English — so you can spot dealbreakers before you book a viewing, not after you’ve instructed a conveyancer.

  • Instant risk scan
  • Plain-English explanations
  • Targeted conveyancer questions

The Problem

Most buyers discover problems with a property after they’ve already committed

Short leases, restrictive covenants, flood risk, boundary disputes, planning issues — these are the things that collapse transactions weeks into the legal process. The information is often available in listing data and public records, but most buyers don’t know where to look or how to interpret what they find. They commit emotionally and financially, then discover the problem. Tetsoma flips that.

AI Property Triage

A preflight check for every property you consider

Our AI scans listed property data and surfaces what matters — risks, red flags, and key questions — translated into language anyone can understand.

Instant risk scan

AI analyses listing data, title information, flood risk, lease length, planning history, and more — surfacing potential dealbreakers you'd otherwise miss until weeks into the legal process.

Plain-English flags

No legal jargon. Every issue is explained in language anyone can understand, with context on what it means for your purchase, your mortgage, and your budget.

Property comparison

Shortlisted multiple properties? See a side-by-side risk comparison so you can weigh up your options with full visibility — not gut instinct.

Conveyancer questions

For properties you want to pursue, Tetsoma generates targeted questions to ask your conveyancer — so you arrive informed, with a focus, not starting from zero.

Before you commit

Run a triage before you book a viewing, before you make an offer, before you pay for a survey. Filter out the wrong properties early and save weeks of wasted effort.

Not legal advice

Tetsoma translates and triages — it doesn't replace your conveyancer. Think of it as an informed first pass that helps you decide where to invest your time and money.

See it in action

You’re considering a two-bed flat in South London listed at £375,000. The listing looks great. The photos are lovely. You’re ready to book a viewing. But Tetsoma has scanned the available data and found three things you should know about first.

This is the kind of intelligence that typically only surfaces weeks into the conveyancing process — after you’ve already paid for searches and committed emotionally. Tetsoma gives it to you before you’ve spent a penny.

Tetsoma AI Triage — 3 flags found

Short lease — 71 years remaining

Most mortgage lenders won't lend on leases below 80 years. You'd likely need to negotiate a lease extension before purchase, typically costing £15,000–30,000. Factor this into your budget or reconsider.

Service charge escalation clause

The lease contains a fixed-increase clause that raises the service charge by 10% every 3 years. Current charge is £2,400/year — projected to reach £3,800 within a decade. Ask for the last 3 years' service charge accounts.

Flood risk — low

No significant flood risk from rivers, sea, or surface water. The property is in Flood Zone 1. No action needed, but your conveyancer may still recommend an environmental search.

How It Works

From listing to decision in four steps

No sign-up fee. No commitment. Just better information before you commit.

1

Share a listing

Paste a property listing URL or enter the address. Tetsoma pulls available data from public records, listing information, and property databases.

2

AI scans for risks

Our AI analyses the data against dozens of known risk factors — lease length, flood zones, planning history, title issues, service charges, and more.

3

Review your triage report

Get a clear, colour-coded report with every flag explained in plain English. Red for dealbreakers, amber for things to investigate, green for all-clear.

4

Decide with confidence

Walk away from bad deals early. For properties you pursue, take Tetsoma's generated questions straight to your conveyancer and start informed.

Who It’s For

Built for buyers who don’t want surprises

First-time buyer, home mover, investor, or buying a second property — Tetsoma gives every buyer visibility before they commit.

First-time buyers

You don't know what you don't know — and that's exactly the problem.

  • Understand what a short lease, restrictive covenant, or flood risk actually means for you
  • Filter out problem properties before you fall in love with them
  • Arrive at your conveyancer with targeted questions, not blank confusion
  • Stop relying on estate agents to tell you about risks they have no incentive to mention

Home movers

You've done this before — but that doesn't make it less stressful.

  • Spot problems before you're in a chain and it's too late to walk away cleanly
  • Compare risk across shortlisted properties before you get emotionally invested
  • Avoid the survey surprise that kills the deal and leaves you out of pocket
  • Move with confidence, not hope — know exactly what you're stepping into

Buy-to-let investors

You evaluate multiple deals at once. Speed and accuracy matter.

  • Preflight every deal in your pipeline before committing time or legal fees
  • Spot lease issues, planning risks, and title problems at scale — not one-by-one
  • Compare risk profiles across shortlisted properties side by side
  • Protect your margins by catching costly surprises before exchange, not after

Second home & holiday let buyers

Buying remotely means you can't just drive past and check. The data can.

  • Flag planning restrictions — Article 4 directions, holiday let licensing, short-term rental rules
  • Identify flood risk, coastal erosion risk, and other location-specific hazards
  • Spot lease or covenant issues before you travel to view
  • Make confident remote decisions without relying on the vendor's word

Why Now

The industry is moving to 28 days. Buyers need to keep up.

Project 28 is a UK government and industry charter pushing the average property transaction from three months down to 28 days. More upfront information will be available earlier than ever before. But information is only useful if buyers can actually understand it. Tetsoma closes that gap.

More upfront data at listing stage
AI triage makes that data usable for buyers
Fewer fall-throughs from informed decisions
Faster transactions for everyone in the chain
