Short answer: PropertyData is mainly a market data service (comparables, valuations, sourcing, yields by area) that also includes a Deal Analyser. If you need that live data, a subscription makes sense. If you already know the price, rent and costs and just need to run the numbers properly, one-off calculators cost less.

Which should you choose?
- Sourcing deals at volume and need comparables: a data subscription such as PropertyData is designed for that.
- Analysing deals you have already found: one-off calculators do the maths without a monthly fee. Property Clues also keeps each deal so you can compare them side by side.
- Doing both: some investors use a data service for research and a one-off toolkit for the detailed appraisal and the tax and compliance side once they own the property.
Free calculators to start with
Property Clues has free tools that need no sign-up: a rental yield calculator, a stamp duty calculator including the buy-to-let surcharge and a motivated seller score. HMRC also has its own official SDLT calculator.
