Granny Flat Finance
Thinking about adding a granny flat for rental income, family, or a smarter first step onto the property ladder? The build is the easy part — the finance is where most people get stuck. Little Home Loans arranges granny flat finance across Australia, matching you to the lenders and loan structures that suit a secondary dwelling on land you already own.
Your enquiry will be handled by the Alpha390 Finance broker team.
Who granny flat finance is for
Granny flat finance suits homeowners adding a second dwelling for rental income or family, investors lifting a property’s yield and value, and buyers weighing a granny flat against a tiny house. Because a granny flat is fixed to land you own, it’s generally easier to finance than a moveable tiny home — but the right structure still depends on your equity, income and the build.
How granny flat finance works in Australia
There are three common ways to fund a granny flat:
- Home equity / loan top-up — draw on the equity in your existing home; often the simplest and cheapest path.
- Construction loan — funds released in stages against the build, suited to larger or custom granny flats.
- Personal or secured loan — for smaller prefab or kit granny flats, or where equity is limited.
Because the granny flat adds value to the land it sits on, lenders treat it as an improvement to real property — which is what makes it more financeable than a tiny home on wheels.
How much does a granny flat cost — and how much can you borrow?
Granny flats in Australia typically cost $100,000–$200,000+, with Queensland builds starting around $95,000 and standard NSW builds commonly $160,000–$190,000. How much you can borrow depends on your available equity, serviceability and the build value. We work with lenders who understand secondary-dwelling finance, so the structure fits your situation rather than a one-size-fits-all box.
Granny flat finance FAQs
Can you get a loan for a granny flat? Yes. A granny flat is usually financed against the land it’s built on — via home equity, a construction loan or a home-loan top-up — rather than as a separate mortgage.
Does a granny flat add value to your property? Typically yes — often $100,000–$200,000 — and, where local rules allow, it can earn rental income (in Queensland, granny flats have been rentable to anyone since 2022).
Is a granny flat or a tiny house the better buy? If you own land and want an appreciating, financeable, income-capable asset, a granny flat usually wins. If you value mobility and a lower entry price, a tiny house can suit.
