Calculate the Net Present Value and Internal Rate of Return of any SA investment property. The metrics serious investors use.
Net Present Value — discounts all future cash flows to today's money. Positive = good investment at your required return.
Internal Rate of Return — the actual annualised return on your equity invested. Compare to your required return.

* IRR is calculated on equity (deposit) invested. NPV uses your required rate of return as the discount rate. CGT is estimated on the capital gain at exit. Bond term assumed 20 years. All projections are estimates — actual returns will vary.
Bond originators compare multiple banks — free service, often better rates than going direct.

Common questions about these metrics
A positive NPV means the investment generates more value than your required rate of return demands. If your required return is 12% and the NPV is positive, the property exceeds that threshold. The larger the positive NPV, the better the investment relative to your benchmark.
An IRR of 12–18% is considered strong for South African residential property. Below 10% may not justify the illiquidity and management effort versus listed property investments. Above 20% indicates exceptional returns, usually with higher risk.
Yield is a static snapshot. NPV and IRR incorporate the time value of money, the full holding period including capital growth, the exit proceeds after CGT, and all cash flows over time. They give a complete picture of investment performance that yield alone cannot provide.
