Rooming House
How much deposit do you need for a rooming house loan in Australia
5 min read · By Daniel Lagden · 23 August 2026
Most rooming house loans in Australia need a larger deposit than a standard investment property, commonly in the range of twenty to thirty five per cent of the property value, though a smaller rooming house that fits a residential lender's policy can sometimes be done with less. The exact figure depends on whether the property is assessed as residential or commercial, the number of rooms, and the lender you use.
Quick summary: the deposit question really comes down to how the property is classified. Treated as a residential investment, you may access a lower deposit and better rate. Treated as commercial or specialist lending, expect a higher deposit because the lender is pricing for a business style asset. Knowing which path your property fits, before you commit, is what lets you plan the deposit accurately.
Residential treatment: the lower deposit path
When a rooming house is small enough and set up in a way that fits a lender's residential policy, it can be financed much like a standard investment property. That generally means a lower deposit and a residential interest rate. This is the outcome worth aiming for where the property allows it, because it is the cheapest way in.
Commercial or specialist treatment: the higher deposit path
Larger rooming houses, purpose built co living properties, or operations run clearly as a business are often assessed as commercial or specialist lending. Here the lender typically wants a larger deposit, because the property is valued on its income and treated as a business asset rather than a home. The trade off is access: this path finances deals that mainstream residential policy will not.
What else affects the deposit
Beyond classification, the deposit can move based on the number of rooms, the property's council approvals and compliance, the strength and documentation of the rental income, and your own financial position and experience. Using equity in another property can also reduce or replace the cash deposit you need, which is a common way investors fund these purchases.
Frequently asked questions
Can I use equity instead of cash?
Often yes. Many investors release equity from an existing property to cover the deposit, which can mean little or no cash out of pocket.
Why is the deposit higher than a normal investment loan?
Because rooming houses carry more complexity and are sometimes treated as a business asset, lenders offset that with a larger deposit.
Does a bigger deposit get me a better rate?
It can help, because a lower loan to value ratio reduces the lender's risk, but the property's classification and the lender's policy usually matter more.
Work out your number
The cleanest way to know your real deposit is to have your specific property and situation assessed against the right lenders, including whether you can use existing equity. Check your rooming house finance options through the form on our rooming house page and we will map it out with you.
