Overview
With Melbourne facing a severe rental shortage and record-high rental yields, building an investment granny flat in your backyard is one of the most lucrative property plays available today. Instead of buying a heavily taxed, separate investment apartment with high body corporate fees, you can manufacture equity and generate significant positive cash flow right in your own backyard. Melbourne Granny Flats specializes in designing and building secondary dwellings specifically optimized for the rental market.

Our investment granny flat service is focused on ROI. We provide end-to-end project management, from site assessment and council approvals to construction and handover. The build includes durable, tenant-friendly finishes chosen for longevity and ease of cleaning, such as hard-wearing vinyl plank flooring, robust laminate benchtops, and semi-gloss paint. We also include the installation of separate sub-meters for water and electricity, ensuring you can easily and accurately bill your tenants for their usage.
Best Suited For
This service is designed for homeowners and property investors who want to generate a strong second income stream, positively gear their property, and increase their overall land value. It is perfect for those who want to take advantage of the recent changes to Victorian planning laws that now allow granny flats to be rented out to the general public, rather than just dependent family members.
Design Considerations
Investment flats need to perfectly balance broad tenant appeal with robust durability. We design open, neutral spaces with modern but timeless color palettes that appeal to a wide demographic of renters. We prioritize functional kitchens with good storage, easy-to-clean bathrooms, and spacious bedrooms with built-in robes. We avoid high-maintenance exterior materials, opting instead for durable cladding and simple, effective landscaping that won't require constant upkeep.

For a successful investment property on your own block, separation and privacy are key. We focus on designing a completely separate access path down the side of your house so tenants don't walk past your living room windows. We also prioritize acoustic fencing, strategic window placement, and private outdoor courtyards for the flat, ensuring that neither you nor the tenant feels watched or disturbed by the other household.
Key Benefits
- Generates significant, reliable positive cash flow
- Capitalizes on the high rental demand in the current Melbourne market
- Substantially increases the resale value and yield of the property
- Provides excellent depreciation tax benefits for investors
- Lower risk and lower entry cost than buying a separate investment property
- No body corporate fees or strata management hassles
Cost Factors
To maximize your Return on Investment (ROI), investment flats are usually built using our standard, highly durable builder's range of finishes rather than luxury custom items. The main cost variables will be the size of the unit (1 vs 2 bedrooms), the ease of site access, and the distance required to run plumbing and electrical services. Installing separate sub-meters is a small upfront cost that saves endless headaches later.

Common questions about this service.
Is it legal to rent out a granny flat to anyone in Victoria?
Yes! Recent changes to the Victorian planning scheme have removed the restriction that required granny flats to only be occupied by a dependent person. You can now legally rent them to the general public.
How much rent can I expect from a granny flat?
This varies by suburb, but a modern, well-designed 2-bedroom granny flat in Melbourne can typically rent for $400 to $550+ per week, providing an excellent yield on the build cost.
How do I charge the tenant for their electricity and water?
We install separate electrical and water sub-meters during construction. The main utility bill still comes to you, but the sub-meter tells you exactly how much the tenant used, allowing you to invoice them accurately.
Can I claim depreciation on a new granny flat?
Yes, because it is a brand new income-producing building, you can claim significant depreciation on the construction cost and the fixtures/fittings over time. We strongly recommend consulting your accountant for specifics.
What finishes are best for a rental property?
We recommend highly durable, water-resistant vinyl plank flooring (rather than easily stained carpet), semi-gloss paint for easy wiping, robust laminate benchtops, and simple, high-quality tapware that won't easily break.
Will renting out a granny flat affect my capital gains tax (CGT)?
Renting out a portion of your primary residence can have CGT implications when you eventually sell the property. We strongly advise speaking with a property accountant to understand how this applies to your situation.
Do I need a property manager for a backyard flat?
You can manage it yourself to save on fees, but many of our clients prefer to use a local real estate agent to handle tenant screening, lease agreements, and bond lodgement for peace of mind.
