About the Property Investment Comparison Calculator

When you have more than one property in mind, it helps to line them up on the same figures. This tool compares rental deals side by side so the differences are clear.

Enter each deal’s price, rent, deposit, mortgage and costs. It compares yield, monthly cashflow, cash needed and a 10-year view, then gives each a comparison score so you can see which deal fits your goals.

Worked example

Deal A£150,000, rent £900: gross yield 7.2%
Deal B£220,000, rent £1,150: gross yield 6.3%
Cash needed at 25% depositDeal A about £45,500 (deposit and stamp duty), Deal B about £67,900
What it showsDeal A earns more per pound invested; Deal B may suit someone who expects more growth in its area

Comparing property deals

How do you compare two buy to let properties?

Use the same assumptions for both: the same deposit percentage, mortgage rate and cost allowances. Then compare yield, cashflow, total cash needed and return on that cash. The tool does this for you.

Is the highest yield always the best deal?

Not always. A higher-yield property may come with higher costs, more voids or slower growth. Looking at cashflow and a longer-term view alongside yield gives a more rounded picture.

What is cash-on-cash return?

The yearly cashflow divided by the cash you put in, including the deposit, stamp duty and fees. It shows how hard your own money is working.
