With an investment property there are 2 distinct sources of measuring Return on Investment (ROI), rental yield and capital growth.

If you have a property worth $500,000, your tenant pays $25,000 per year in rent and you pay $5,000 a year in costs, you have a gross rental yield of 5%, and a net rental yield of 4%.
For example in 2020 RealEstate.com calclulated the average rental yield across 10 Gold Coast suburbs-:
| Avg. Rental Yields Gold Coast | |
|---|---|
| Surfers Paradise | 3.28% |
| Miami | 4.1% |
| Jacobs Well | 4.59% |
| Worongary | 5.2% |
| Mt Tamborine | 4.61% |
| Clear Island Waters | 4.04% |
| Arundel | 5.13% |
| Ashmore | 5.11% |
| Broadbeach Waters | 3.74% |
| Mermaid Beach | 2.69% |

Note COVID 19 has affected these numbers on the Gold Coast. Fox's Real Estate Agents Southport Gold Coast report a serious lack of availability of properties, both for rent and sale.
Capital Growth is the appreciation (or negative return) of the asset itself expressed as a percentage %.
If say you bought a unit at Main Beach on the Gold Coast for $125,000 in 1991 what would be the price now 2021 (30 years) if you gained a 10% pa Capital Growth on average?
| Capital Growth $125,000 30 years | |
|---|---|
| 5% | $540,242.80 |
| 6% | $717,936.40 |
| 7% | $951,531.88 |
| 8% | $1,257,832.11 |
| 9% | $1,658,459.81 |
| 10% | $2,181,175.28 |

You may see a better overall return from a property with a lower rental yield and a higher capital growth.
