Rental yield is one of the first numbers investors look at, but it is also one of the easiest to oversimplify. A property with a higher advertised yield is not automatically a better investment, and a property with a lower yield is not automatically poor. The figure only becomes useful when it is read alongside costs, risk and long-term appeal.

Gross yield is the simple version. It compares annual rent with the purchase price. For example, if a property rents for $500 per week, the annual rent is $26,000. If the purchase price is $650,000, the gross yield is 4 percent. That gives a quick comparison, but it does not tell the whole story.

Net yield is more useful because it allows for costs. Victorian investors need to consider council rates, water charges, insurance, owners corporation fees where relevant, property management, maintenance, land tax if applicable, compliance costs and vacancy. A townhouse with a lower gross yield but modest outgoings may perform better than an apartment with higher rent and substantial owners corporation fees.

Vacancy risk deserves particular attention. A rental estimate is only meaningful if the property can attract and retain renters at that level. Investors should look at similar advertised rentals, speak with local property managers and consider the depth of tenant demand. Transport, heating and cooling, storage, natural light and secure parking can all affect leasing confidence.

Property condition also shapes the real return. A home that needs a new roof, rewiring, drainage work or major appliance upgrades can turn an attractive yield into a thin one. Older properties can be excellent investments, but the maintenance allowance needs to be realistic from the beginning.

Investors should also think about who the likely renter is. A one-bedroom apartment near transport may appeal to a different tenant pool than a three-bedroom home near schools. Neither is inherently better. The important question is whether the property matches a clear rental market and whether that market is deep enough if one renter moves out.

Borrowing costs are another part of the picture. In July 2023, many investors were reassessing cash flow after a period of rising interest rates. A purchase that looked comfortable at one repayment level could feel different after loan costs, tax settings and maintenance were included.

Rental yield is a starting point, not a verdict. A careful investor uses it to ask better questions: What are the true costs? How durable is the rent? What happens if the property is vacant for a few weeks? And will this property still make sense if the market takes longer to move than expected?
