Professional modelling. Instant results. Completely free.
Purchase costs, stamp duty, mortgage metrics, cashflow, gross and net yield, cash-on-cash ROI, 5-year total return and a detailed monthly breakdown across every major UK investment strategy.
Select your investment strategy from the tabs above — Buy-to-Let, HMO, BRRR, Short-Term Let or Rent-to-Rent. Each tab is structured to walk you through the full deal from purchase costs through to cashflow and return on investment.
The deal verdict at the bottom tells you whether the numbers stack up. Green means strong — amber means marginal — red means it needs work.
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.
This tool shows you if a deal works today. My Property Organiser tracks whether it is working every month income, expenses, yield drift, MTD compliance and AI alerts. From £14.95/month.
