Financing a granny flat is becoming a mainstream conversation with lenders, not a niche one. Understanding how that conversation actually goes helps you walk into it prepared rather than guessing at what a broker will ask.
The Lending Landscape Has Shifted
NAB reported a 21% jump in renovation loan activity in 2025, with a significant portion of that going toward granny flat builds specifically. Lenders are increasingly familiar with this type of project, which can make the approval process smoother than it used to be even a couple of years ago.
Common Ways Melbourne Homeowners Fund a Build
Broadly, Melbourne homeowners fund a build like this a few different ways: drawing on existing home equity, a dedicated renovation or construction loan, or refinancing to release equity built up in the main property. Which option suits you depends on your existing loan structure, your lender’s specific policies, and your broader financial position. This is genuinely a conversation for a mortgage broker or financial adviser, not something to decide from a blog post.

Are There Grants Available?
Some homeowners ask about government support before assuming finance is entirely self-funded. Our overview of granny flat grants in Victoria covers what’s currently available and what typically isn’t, so you’re not relying on outdated information from a forum post.
Why Fixed Pricing Helps Your Loan Application
What we can control is making the numbers easy to plan around. Every Innovista price is turnkey and fixed at contract, covering the building permit, site connection and full build, with any regional or access surcharges disclosed upfront rather than discovered mid-project. That matters for financing specifically, because lenders and brokers work far more easily with a fixed, itemised price than an open-ended one that could shift once construction starts.
Financing an Investment Build Specifically
If you’re financing this as an investment property rather than a family use case, your accountant will also want to factor in depreciation and negative gearing. Our guides to tax deductions and negative gearing for granny flats are a reasonable starting point before that conversation.
What to Bring to Your Broker
Our four tiers range from $198,000 (Affordable) to $265,000 (Luxe), all for a 60m² 2 bed/1 bath base, with clear, published adjustments for extra beds, baths or a smaller 1-bedroom layout. That’s the number your broker will need first, alongside a written, itemised quote rather than a verbal estimate.
