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.
| Tool | From (per month) | Free trial or tier | Finds deals for you | Depth of analysis |
|---|---|---|---|---|
| PropDetect | £15 | 3 free analyses, no card | Deal Radar watches Rightmove 24/7 and emails only the matches that stack | Full appraisal per deal: photo-based refurb costs, comparable-sales GDV, rent, and a strong / solid / avoid verdict across six strategies |
| PropertyData | £14 ex VAT | 14 days, no card | Sourcing alerts and a scan of 75,000+ on-market listings against strategies | Market analytics first: local data, valuations, comparables, a Deal Analyzer for buy-to-let assessments |
| Lendlord | Free tier; Premium £12 | Free tier, no card | Property sourcing across auctions and agent listings | Deal and flip analysers alongside its core portfolio, tenant and finance management |
| Dealsourcr | £79.99 ex VAT, billed yearly | 7 days, card required | Deal-finding across strategy types (BMV, HMO, R2SA, motivated sellers) | Calculators and an AI Deal Analyser, capped at 5 analyses a month on the Pro plan |
| Searchland | £195 ex VAT, billed yearly | Demo first, then a trial | Land and development site sourcing from planning, ownership and land datasets, not residential portal listings | Site intelligence rather than deal appraisal: the returns appraisal is a paid add-on. Includes MCP tokens so Claude or ChatGPT can query its data directly |
| Property Filter | £100 ex VAT (£80 annual) | 8 days | Deal-finding across the portals with motivated-seller signals, wrapped in a coaching membership | Membership first: sourcing tools plus live coaching and community. Analysis is the member's job with their training |
| PropertyEngine | £24.99 ex VAT | 14 days, card required | Sources deals across portals with speed as its pitch | Calculators, comparables and deal packaging alongside the sourcing |
| DealFlow AI | Credit packs from £9 | One free analysis a day, no account | No sourcing: you paste a Rightmove link | A fast verdict: buy, maybe or avoid, with yield and cash flow. Lighter than a full appraisal, priced accordingly |
| PropAI | £40 | 5 days, 1 property | No sourcing shown on its pages; you enter the property details | AI appraisal of a property you supply: refurb estimate, stress tests, rating across four strategies |

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. 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.
Property Filter is the best-known name in deal-finding, and it is honestly a different purchase: a membership with live coaching and community wrapped around the sourcing tools, priced accordingly at £100 a month plus VAT. If you want to be taught to source with tools included, that is its job. If you want the finding and the appraisal done for you by software, it is not trying to be that. Their own pricing page flags rises due, so check it.
PropertyEngine pitches speed of sourcing at a mid price, with calculators and packaging attached. DealFlow AI sits at the opposite end of the spectrum from a full appraisal: paste a link, get a buy, maybe or avoid verdict with yield in seconds, free once a day. As a first-pass screen it is genuinely useful; it does not attempt the room-by-room refurb or evidenced valuation that separates a screen from an appraisal, and to its credit it does not pretend to.
Searchland is the one people mention in the same breath as these tools that is genuinely solving a different problem. It is land and development software: planning applications, ownership records and strategic land data, aimed at developers and land sourcers rather than someone appraising a three-bed terrace off Rightmove. Its returns appraisal is a paid add-on rather than the core. It is also the only tool here with an MCP connector, so you can query its data from inside Claude or ChatGPT, which is a genuinely good idea and something we do not offer yet. If you source development sites, look at Searchland and largely ignore this page; if you source residential deals, it is not really a competitor at £195 a month.
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 tools on this page offers, and entry is £15 a month. Deal Radar watches Rightmove on every plan, with Zoopla and OnTheMarket available as £20 a month add-ons, and the same house found on two portals is analysed and alerted once. The analysis itself reads all six portals including the Scottish centres, free on every plan.
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 £15 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?
Most do. 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. Property Filter gives 8 days, PropertyEngine gives 14 with a card, and DealFlow AI gives one free analysis a day with no account at all. Searchland is the exception: it runs a demo first and offers a trial after that.
Why should I trust a comparison written by one of the vendors?
Verify it. Every factual claim here is taken from the other tools' own public pages, with the sources and the date named under the table. The judgements are openly ours. If a price or feature has changed since, their page is right and this one needs updating; tell us and we will fix it.
Judge it on a real deal
The honest way to choose deal analysis software is to run the same property through it. Create a free account, paste any Rightmove listing, and read the verdict PropDetect gives it: refurb costs, comparable valuations, rent, GDV and ROI across six strategies. Your first 3 analyses are on us, no card needed.
