As Australia grapples with rising property prices and shifting demographics, savvy investors are turning their attention to one of the most underestimated real estate opportunities: granny flats for investment Melbourne. In 2025, these compact, self-contained dwellings aren’t just a secondary feature of a home; they’re a primary investment strategy. Here’s why granny flats, especially in Melbourne and regional Victoria, are becoming one of the most sought-after strategic property investments available.

What Are Granny Flats?

Granny flats, also known as small secondary dwellings (SSDs) or accessory dwelling units, are self-contained homes typically located on the same lot as a primary residence. Ranging from 1-bedroom to 2-bedroom layouts, they include their own kitchen, bathroom, living area, and private entrance.

Modern granny flats have evolved from simple backyard cabins into high-end mini homes, complete with luxury finishes and full compliance with local building regulations, delivering exceptional rental income from granny flats while adding significant property value.

Furthermore, understanding what granny flats are and how they benefit you helps investors recognize their full potential.

Why Granny Flats Outperform in 2025’s Investment Market

High-Yield Rental Returns

One of the biggest appeals of granny flats for investment Melbourne is their income potential. In the Melbourne region, investors are regularly seeing rental returns exceeding 10-13%. With housing demand skyrocketing and affordable rentals dwindling, granny flats provide a lower entry point for tenants and a high cashflow opportunity for landlords.

Compared to traditional rental properties, granny flats:

• Require less capital to build ($190,000-$255,000 vs $600,000+)
• Yield higher rent-to-cost ratios (10-13% vs 3-4%)
• Have shorter construction timelines (12-16 weeks for quality builds)
