It is one of the first questions Melbourne homeowners ask when they start thinking seriously about building a secondary dwelling. How much can I actually rent it out for?

The honest answer is that granny flat rental income in Melbourne varies more than most online guides suggest. The suburb matters. The finish level matters. The floor plan matters. Whether the secondary dwelling has a separate entry, separate utilities and full kitchen facilities matters.

This guide covers what Melbourne homeowners with G-Flat™ secondary dwellings are realistically achieving in weekly rent in 2026, what drives the variation and what decisions you can make at the build stage to maximise the rent your secondary dwelling earns.

What Melbourne Granny Flats Are Renting For in 2026

Across Melbourne’s established suburbs and growth corridors, quality two bedroom secondary dwellings in good condition are achieving weekly rents broadly in the following ranges.

Inner Melbourne suburbs within 15km of the CBD, including areas like Footscray, Brunswick, Coburg, Northcote and Preston: approximately $450 to $600 per week for a well-presented two bedroom secondary dwelling with a quality finish.

Middle ring suburbs between 15 and 30km from the CBD, including areas like Ringwood, Box Hill, Glen Waverley, Dandenong and Frankston: approximately $380 to $520 per week for a comparable dwelling.

Outer growth corridors including Tarneit, Point Cook, Berwick, Craigieburn and Melton: approximately $320 to $450 per week depending on the estate, the finish level and the proximity to amenities.

Regional Victoria including Geelong, Ballarat and areas beyond 70km from the CBD: approximately $280 to $400 per week for a quality secondary dwelling.

What Drives the Variation in Granny Flat Rent

Understanding what pushes weekly rent up or down helps you make better decisions at the build stage before the secondary dwelling is completed.

Finish level. A Luxe G-Flat™ consistently achieves higher weekly rent than an Affordable G-Flat™ in the same suburb. The 3 metre ceilings, curved kitchen island, Bosch appliances and underfloor bathroom heating present noticeably better at inspection and attract tenants who are prepared to pay a premium for quality. In most Melbourne suburbs the weekly rent premium for a Luxe over an Affordable G-Flat™ is approximately $50 to $100 per week. Over a full year that premium is $2,600 to $5,200, which is meaningful in the context of the approximately $67,000 difference in build cost between the two packages.

Number of bathrooms. The Lana 2 G-Flat™ with two bathrooms consistently achieves a rent premium of approximately $30 to $60 per week over the single-bathroom Lana in the same suburb and at the same finish level. For a two-person tenancy, two bathrooms removes a genuine daily inconvenience and tenants recognise that in what they are prepared to pay.

Private separate entry. A secondary dwelling with its own entry independent of the primary dwelling’s yard achieves higher rent and attracts more enquiries than one where the tenant has to walk through the landlord’s garden to get to their front door. Think about entry positioning during the site assessment stage.

Separate utilities. Tenants in Melbourne’s rental market expect to manage their own electricity account. A separately metered G-Flat™ is more attractive to quality tenants than one where utilities are shared or on-charged through the landlord. Our guide to separate electricity meter granny flat Victoria covers how to set this up.

Presentation and condition. A brand new G-Flat™ at handover presents at its best. Maintaining that presentation, responding promptly to maintenance requests and keeping the dwelling in good condition sustains the rent level over time and reduces vacancy between tenancies.

Suburb amenity. Secondary dwellings close to train stations, schools, shopping centres and employment precincts achieve higher rents than those in areas with limited walkable amenity. This is not something you can change but it is worth understanding when assessing the rental potential of a build on your specific block.

How Rental Income Offsets Build Cost

For most Melbourne homeowners the primary motivation for renting out a G-Flat™ is to offset the cost of the build against their mortgage. Understanding how the weekly rent tracks against a typical loan repayment is a useful way to assess the financial picture.

A $200,000 construction loan at current standard variable rates over 25 years produces a principal and interest repayment of approximately $1,100 to $1,300 per month depending on the interest rate. A G-Flat™ generating $400 per week in rent produces approximately $1,730 per month in rental income. In that scenario the rental income more than covers the loan repayment and generates a net monthly surplus.

The above is a simplified illustrative example only. Actual loan repayments depend on the interest rate, loan term and individual financial circumstances. Rental income is not guaranteed and is subject to vacancy, market conditions and property management costs. This is not financial advice. Always speak with a licensed mortgage broker and a financial adviser before making any borrowing or investment decisions.

What Happens Between Tenancies

Vacancy between tenancies is the main factor that affects actual annual rental income beyond the weekly rent figure. A secondary dwelling that achieves $450 per week but sits vacant for eight weeks per year earns less than one achieving $400 per week with two weeks vacancy.

Quality secondary dwellings in established Melbourne suburbs and growth corridors are currently experiencing low vacancy rates. Demand for self-contained smaller dwellings consistently exceeds supply in most Melbourne rental markets. A well-presented, well-located G-Flat™ managed by a competent property manager or attentive owner-landlord typically achieves short vacancy periods between tenancies.

The factors that reduce vacancy are largely the same as the factors that increase weekly rent. Finish quality, separate entry, separate utilities and good presentation all make the secondary dwelling easier to re-tenant quickly when a tenancy ends.

Before a tenancy starts, make sure you have the right lease agreement in place and the correct insurance coverage confirmed.

Frequently Asked Questions

How much can I rent a granny flat for in Melbourne’s western suburbs? In Melbourne’s western growth corridor, including Tarneit, Point Cook, Hoppers Crossing and Werribee, quality two bedroom secondary dwellings are generally achieving approximately $320 to $420 per week depending on the estate, the finish level and proximity to train stations and shopping centres.

Does a Luxe G-Flat™ earn significantly more rent than an Affordable G-Flat™? In most Melbourne suburbs yes, though the premium varies. The weekly rent premium for a Luxe over an Affordable G-Flat™ in the same suburb is approximately $50 to $100 per week. Whether that premium justifies the approximately $67,000 difference in build cost depends on how long you plan to rent the secondary dwelling and what other goals the build serves.

Can I charge more rent if the granny flat includes furniture? Furnished secondary dwellings can achieve a premium in some markets, particularly in inner Melbourne suburbs close to universities or short-term employment hubs. However, furnished properties also carry higher management complexity, more frequent tenant turnover and higher maintenance costs. Most Melbourne homeowners renting a G-Flat™ long term choose unfurnished.

Do I need to declare granny flat rental income on my tax return? Yes. Rental income from a secondary dwelling is assessable income in Australia and must be declared on your annual tax return. You can claim deductions for expenses relating to the rental property including interest on borrowings, depreciation, property management fees, insurance and repairs. Speak with a registered tax agent for advice specific to your situation. Our guide to granny flat negative gearing Victoria covers the tax picture for rental G-Flat™ owners in more detail.

What is the best suburb in Melbourne for granny flat rental income? Inner and middle ring Melbourne suburbs with strong amenity, good public transport and high rental demand consistently deliver the strongest weekly rents for secondary dwellings. However, build costs are the same regardless of suburb, so the net return relative to build cost is often comparable between inner suburbs with high rents and outer suburbs with lower rents but also lower all-in property costs.
