  2. Mortgage tab: Set your interest rate and choose between interest-only or capital repayment.
  3. Income tab: Add rental income, occupancy rates and void periods where applicable.
  4. Running costs tab: Include management fees, insurance, service charges, ground rent and maintenance.

The deal verdict at the bottom tells you whether the numbers stack up. Green means strong — amber means marginal — red means it needs work.

About This Tool

The UK's Most Comprehensive Free Property Deal Analyser

My Property Organiser's Deal Analyser covers the five most common UK residential property investment strategies. Unlike basic calculators, this tool accounts for stamp duty surcharges for overseas buyers, HMO void periods, BRRR refinance modelling, STL occupancy rates, and rent-to-rent margin analysis — all in one place.

The 5-year total return projection combines cumulative cashflow with capital growth, giving you a more complete picture of the real-world return on your investment — not just the first-year yield.

This calculator is used by property investors and UK property investment agencies to quickly assess deal viability before committing to further due diligence. It does not constitute financial advice — always seek independent professional guidance before investing.
