Comparison
Best property deal analysis software in the UK, compared
We build PropDetect, so read this the way you would read any vendor's comparison page: the facts about other tools below come from their own public pricing and feature pages (checked 11 August 2026, sources linked in the notes), and everything else is clearly our view. The honest headline is that these tools solve different problems, and the right one depends on which problem you actually have.
The short version of our opinion: if you want raw market data for research, PropertyData is excellent value. If you want portfolio and tenant management with some deal analysis attached, Lendlord's free tier is hard to argue with. If you want deals found, fully analysed and given a verdict without you doing the work, that is the specific job PropDetect was built for.

What to look for in a deal analysis tool
Strip the marketing away and there are four questions that matter. Does it find deals, or only analyse the ones you bring? How deep is the appraisal, meaning does it stop at yield and stamp duty or does it price the refurb, evidence the end value and model the exit? Does it commit to a judgement, or hand you a spreadsheet and wish you luck? And what does it cost against the time it saves?
Where tools quietly differ most is the middle two. Plenty of software calculates; very little values. A yield figure from an asking price takes one division. A defensible GDV takes comparable sold prices, floor areas and a method for outliers, and a refurb estimate takes actual condition evidence rather than a guess per square metre. Ask any vendor where their end value and refurb numbers come from; the answer tells you whether it is an appraisal or a calculator.
- Sourcing: alerts on new listings that match your criteria, not just a search page
- Valuation basis: comparable sold prices with the method shown, not an index estimate
- Refurb costing: from the property's actual condition, not a flat rate
- A verdict: the tool should commit, and show the reasons, so you can disagree intelligently
- Strategy coverage: the same property can fail as a flip and work as an HMO; you want both run
Where each tool genuinely fits (our view)
PropertyData is the researcher's tool. Its local market data, postcode analytics and comparables are the best-known in the UK market, its pricing is fair, and its 14-day no-card trial is the most generous entry point here. Its Deal Analyzer does buy-to-let assessments, but the product's centre of gravity is data you interrogate yourself.
Lendlord is the landlord's operating system. Portfolio tracking, tenant management, open banking, Making Tax Digital submissions, plus deal analysers on the side, with a genuinely free tier. Two things from its own pages worth knowing: its help centre states it does not currently cover Scotland, and it partners with PropertyData for estimates.
Dealsourcr is deal-finding first, with strategy searches from negative equity to R2SA and data back to 2019. It is also the most expensive tool here at its displayed pricing, and its AI analysis is capped at five deals a month on the lower plan.
PropAI is an analyser you feed by hand. Its appraisal of a single property is genuinely deep, with refurb estimation, stress testing and a rating, and at £40 a month it is priced accordingly. It shows no sourcing or alerts on its pages, so finding the deal remains your job.
PropDetect does the end-to-end job: Deal Radar watches Rightmove around the clock, every match gets the full appraisal automatically, and only the deals that stack reach your inbox, each with a strong, solid or avoid verdict across six strategies and every figure editable. In our view that combination, sourcing plus committed verdict in one loop, is what none of the other four offers, and at £7.99 a month entry it undercuts all of them.
Frequently asked questions
What is the best property deal analysis software in the UK?
It depends on the job. For market research data, PropertyData is the established choice. For portfolio and tenant management with analysis attached, Lendlord has a free tier. For automated deal sourcing with a full appraisal and verdict on every match, PropDetect is built for exactly that, from £7.99 a month.
What is the difference between deal sourcing software and deal analysis software?
Sourcing software finds candidate properties; analysis software judges them. Many tools do one well. PropDetect runs both as one loop: its Deal Radar finds matches on Rightmove and the analysis engine appraises each one before it reaches you.
Do any of these tools offer a free trial?
All five have a free route in: PropertyData gives 14 days with no card, Lendlord has a permanently free tier, Dealsourcr gives 7 days with a card, PropAI gives 5 days on one property, and PropDetect gives every new account 3 free analyses with no card needed.
