What is the Property Leverage Calculator?
The Property Leverage Calculator helps you model how using sensible UK leverage can accelerate your ability to purchase additional properties, grow rental income, and ultimately support earlier or more secure retirement. By combining UK mortgage rates, rental yields, refinancing rules and cautious long-term growth assumptions, it shows how a single property can compound into a small portfolio over time.
How the Calculator Works?
This calculator models property growth, mortgage amortisation, equity build-up, refinancing points, and rental income year by year. Using conservative UK assumptions for house price growth and interest rates, the tool projects when you unlock enough equity to refinance and acquire further properties. It then runs the model forward to show how cash flow, equity and property count grow over time, and how this can support retirement income goals.
Step One: Enter Your Property Details
Input purchase price, deposit, mortgage interest rate, term length and expected rent.
Choose baseline assumptions for capital growth and rent inflation.
Step Two: Model Equity Growth and Refinancing Opportunities
The calculator tracks outstanding mortgage debt and rising property value to determine when you naturally reach refinancing milestones, allowing you to extract capital for the next deposit.
Step Three: Build the Portfolio & View Long-Term Outcomes
Each time equity allows a refinance, the model adds another property to your portfolio.
You’ll see projected property count, rental income, equity growth, and cash flow over time.

What is the Downsizing Your Property In Retirement Calculator?
The Downsizing Your Property In Retirement Calculator compares the long-term financial impact of staying in your current home versus moving to a cheaper one, showing equity released, changes in running costs and the cumulative benefit of downsizing over time.
What does this calculator show me?
It models how leverage can help you acquire additional properties using equity released through refinancing, while projecting rental income, cash flow and long-term portfolio value.
How does it work?
The model calculates mortgage paydown, property appreciation and rental income each year. It tracks when your loan-to-value reaches a refinance trigger (for example 75 percent LTV) and automatically adds a new property using the released equity.
Does it include UK-specific assumptions?
Yes. It includes UK mortgage rates, realistic long-term UK house price growth, standard LTV refinance limits, and typical rental yield ranges.
Does it account for risk?
Yes. All growth assumptions are cautious, and you can adjust interest rates or growth to stress-test scenarios.
