Answering: What do Australian lenders mean by “boarding house finance”, and how does that apply to a purpose-built nine-room Class 1b co-living property in Melbourne?

Estimated reading time: 12 min read

“Boarding house finance” is a loan conversation, not a description of your property. If what you are buying is a purpose-built, single-storey Class 1b dwelling with nine rooms and nine bathrooms on one title, brief your lender on exactly that, with the documents to prove it, and do not let a search phrase become the label on your loan file. The Harmony Group builds that one product in Melbourne, for investors from every state who start with at least $600,000 in cash, usable equity, or a combination of both.

The words matter because the loan, the council file and the building certificate each use their own vocabulary for related ideas. Mixing them is how a sound project ends up assessed against the wrong policy.

Overview

  • The phrase you hear and the property you buy are two different things. Victoria’s legal word is rooming house.
  • Describe the asset as nine rooms, nine bathrooms, Class 1b, a registered rooming house, purpose-built.
  • Give the lender the certificate, the registration, the operator arrangement and the rent evidence up front.
  • At banks and other authorised deposit-taking institutions, APRA’s buffer applies to every bank investor loan; ask how your lender counts nine rents.

A phrase, not a property type

You may hear “boarding house finance” from a broker, or see it in search results, as a catch-all for loans against property that is let room by room. It is shorthand, and on its own it does not tell a lender what the building is.

Part of the confusion is geographic. In New South Wales, “boarding house” is a specific planning category: under the state’s housing policy, a boarding house must be managed by a registered community housing provider in perpetuity. New South Wales treats co-living housing as a separate category again, which must contain at least six private rooms. A phrase carried across the border from that system says nothing useful about a privately owned building in Melbourne.

Victoria’s word is rooming house. Consumer Affairs Victoria defines it as a building where one or more rooms are available for occupancy by four or more people, in return for rent. That is the vocabulary your council, the regulator and a well-briefed lender will use, so it is the vocabulary your file should use too.

The words that do describe a Harmony nine-bed

Each part of the system has its own precise term, and a good loan file uses all of them in the right place.

  • The product: one purpose-built dwelling, nine rooms, nine bathrooms, single storey, on one title, with shared living space.
  • The building classification: Class 1b under the National Construction Code. The 2025 edition caps Class 1b at a building that ordinarily houses up to 12 people and holds no more than 300 square metres of floor in total.
  • The use: a rooming house under Victorian law, registered with the local council as prescribed accommodation under the Public Health and Wellbeing Act 2008.
  • The planning provision: Clause 52.23 of the Victoria Planning Provisions, whose conditions are set out in our article on why nine bedrooms is the planning threshold.
  • The operator: the person or body corporate who holds the rooming house operator licence, with the property manager named as a relevant person on that licence.
  • How it was built: designed and built new for this use. It is not an existing house adapted room by room.

None of those terms is “boarding house”. If a broker’s application form forces a choice of property type, ask which option the lender’s own policy uses for a Class 1b rooming house, and get that answer in writing before the file goes in. The approvals behind each term are covered in our guide to the three approvals a Victorian nine-bed needs.

Why the label on the loan file matters

A lender assesses the security against a policy for that type of property. How the property is described on the application can decide which policy applies, which can shape how much the lender will lend against the property, how the valuer approaches it, and how much of the rent the lender will count when it tests whether you can repay.

Lenders differ, and no one can promise how a particular lender will treat a particular property. What you can control is the accuracy of the description and the quality of the evidence. A file that says “nine rooms, nine bathrooms, Class 1b, registered rooming house, purpose-built, rent evidenced by room” gives the credit team something specific to assess. A file that says “boarding house” leaves them to guess.

The valuation side is covered in depth in how banks and valuers assess a nine-bed co-living loan, including why an income approach can matter more than comparable sales for a property let across nine agreements.

What to put in front of the lender

Brief your broker before the application is drafted, not after a credit team has asked questions. A complete file for a nine-bed usually needs:

  • the Class 1b certification, or for a build, the plans and building permit showing the Class 1b design;
  • the council registration as prescribed accommodation, or the plan for lodging it before the first residents move in;
  • who will hold the rooming house operator licence, and the property management agreement;
  • rent evidence by room, with its source and date, rather than a single building figure;
  • the building contract and the project cost, including any costs beyond the base build;
  • your own income, existing debts and living expenses, which drive the serviceability test whatever the property is.

Then ask three questions and keep the answers: which property type the lender will record, which valuation approach it expects, and how much of the room-by-room rent it will count.

The settings banks apply, and the income they test

Two of the Australian Prudential Regulation Authority’s settings shape the residential loans that banks and other authorised deposit-taking institutions write. The mortgage serviceability buffer remains at three percentage points, so you are tested at your loan rate plus three. Since 1 February 2026, lenders can write no more than 20% of their new mortgage lending at debt of six times income or more, a limit applied separately to owner-occupier and investor lending. APRA’s limit excludes loans for the purchase or construction of new dwellings, so ask your broker whether that exclusion applies to your loan rather than assuming it does. Nothing on APRA’s publications list to 27 October 2026 changes either setting.

The income side is where a nine-bed differs from a single-household rental, because the lender is looking at nine rents rather than one. Average figures based on most recent projects: around $380 a room a week, $3,442 a week across nine rooms, $179,010 a year in gross rental income, on a base project cost of $1,574,000, or $1,650,250 including additional considerations. The $380 is rounded from an average of $382.50 a room ($382.50 x 9 rooms x 52 weeks = $179,010). Measured against that base project cost, gross yield comes to 11.36%, based on recent acquisitions.

The same client figure set gives the comparison: a standard investment property at the same $1.5 million price rents for around $865 a week, $45,000 a year, a 3% gross yield. Separately, the historical average gross yield across The Harmony Group’s delivered projects is 10.8%. All of these are gross figures. The net position depends on your loan structure, deposit and tax position, and how much of the gross rent a lender counts is the lender’s own policy.

What the label does not settle

Getting the finance vocabulary right does not answer the tax question, and the two should not be mixed. How a property is treated for tax is a question for your accountant or tax adviser.

That includes the 2027 negative gearing changes, which were enacted on 26 June 2026 and apply from 1 July 2027. A Harmony nine-bed is a newly built dwelling, and whether it meets the reform’s definition of an eligible new build depends on the final legislation and your own advice. The enacted law and what is still open are set out in the 2027 negative gearing changes are now law.

Where The Harmony Group fits

The finance conversation starts with the floor: a minimum of $600,000 in cash, usable equity, or a combination of both. How that applies to your own position is a question for your broker; what $600,000 of usable equity means in practice is walked through in what $600,000 in usable equity could do.

From there, the team’s work is designed to make the lender’s job easier. Class 1b certification is confirmed on every property before commitment. Each site passes the 118-point method, supported by SQM Research market data, before anyone is asked to commit. The untitled land strategy buys time for co-living finance, and the team works to a typical finance timeline of around three to six months. Clients pay The Harmony Group $0: the builder pays at settlement, at the same rate across the panel.

The team brings 15+ years of specialist accommodation experience to the conversation. All of it sits inside The Harmony Formula, from the location stage through the build to the specialist partners who run the property once it is let.

Frequently asked questions about co-living finance

Q: Should I describe a co-living property as a boarding house on a loan application?

No. Use the words Victoria uses. A Harmony nine-bed is a purpose-built dwelling with nine rooms and nine bathrooms, classified Class 1b and registered as a rooming house. “Boarding house finance” is a phrase people use for loans on room-by-room property, and in New South Wales “boarding house” is a planning category that must be managed by a registered community housing provider. Describe the property in its own terms on the loan file.

Q: Can I use a standard residential investment loan for a nine-bed co-living property?

It depends on the lender and how its policy treats a Class 1b rooming house. Some settings are the same for every investor borrowing from a bank or other authorised deposit-taking institution: the three percentage point serviceability buffer applies whatever the property, and the debt-to-income limit applies too, except to loans for the purchase or construction of new dwellings, which APRA excludes. Ask your broker which property type the lender will record, and get the answer in writing before you apply.

Q: How much do I need to invest in a Harmony nine-bed?

The minimum is $600,000 in cash, usable equity, or a combination of both. How that is structured for you, and how much a lender will add to it, depends on your income, existing debts and the lender’s assessment, so talk to your broker before you commit to anything.

Q: What will a bank test before it approves the loan?

Your ability to repay, whatever the property. Banks and other authorised deposit-taking institutions assess repayments at your loan rate plus a three percentage point buffer, which APRA has kept steady. Since 1 February 2026, each of them can write no more than 20% of its new investor lending to borrowers whose debt is six or more times their income. Your income, existing debts and living expenses go into that test before the property’s rent is counted.
