Not financial advice. For educational purposes only. This is an illustrative projection on fixed assumptions, not a forecast. House prices, rents and investment returns are uncertain and rarely move in a straight line; the result is very sensitive to the growth and return figures you choose. It ignores tax and the non-financial value of owning or renting. Verify figures with a broker, adviser and accountant before deciding.

Thinking of buying as an investment rather than to live in? Run the full deal analysis with yield, cashflow and tax.

The answer lives in the assumptions. Rent vs buy is not a fixed fact: it turns on house price growth, the mortgage rate, the rent, and what the renter earns on the deposit. Buying tends to win the longer you stay, because upfront costs and early interest are spread over more years of equity growth. Nudge the sliders and watch the headline flip.
