Rental Income Boost: How a Granny Flat Increased Property Yield

Tenant in a property with high rental income thanks to granny flat

Maximizing rental income is one of the most effective ways to enhance the performance of an investment property. Recently, we helped a client nearly double their rental earnings by adding a granny flat to their property. Here’s how this single upgrade made a significant difference in both their cash flow and overall property value.

The Investment Strategy for Increasing Rental Income

Our client initially purchased a property for $670,000, generating $550 per week in income. This gave them a gross yield of 4.2%. But we saw an opportunity to boost their returns. By investing $200,000 to add a granny flat, we aimed to increase both the property’s cash flow and its long-term value.

How a Granny Flat Boosted Rental Income and Property Yield

Adding the granny flat delivered some quick and impressive wins:

  • Higher Income: The addition of the granny flat increased the total earnings from $550 to $1,020 per week. The main house now rents for $570, and the granny flat generates an extra $450 weekly.
  • Increased Yield: This upgrade boosted the property’s return to 6%, offering a better return on the initial investment.
  • Enhanced Property Value: Beyond generating income, the granny flat also added significant value to the property, growing our client’s equity and setting them up for future investment opportunities. Read more about Equity Building in the Guide to Property Valuation and Equity.

Long-Term Benefits of Adding a Granny Flat to Your Rental Property

Granny flats and other smart property upgrades offer long-lasting benefits, including:

  • Building Equity: The increase in property value means more equity, which can be used for future investments.
  • Improved Cash Flow: With a higher yield, cash flow improves, offering greater financial flexibility and increased monthly income.
  • Attracting Quality Tenants: A well-designed granny flat appeals to a wider tenant pool, leading to higher rents and fewer vacancies.
