Nine-bed co-living or a traditional rental: how do they compare at the same price?

· Yannick Ieko

Answering: How does a purpose-built nine-bed co-living property compare with a traditional single-tenant rental at the same price in Australia?

Estimated reading time: 12 min read

If you want one tenancy, the simplest set of rules and the lightest management load, a traditional rental is the better fit. If you have at least $600,000 in cash, usable equity or both, and you want gross income built from nine leases instead of one, a purpose-built nine-bed is worth putting beside it. The Harmony Group builds that nine-bed in Melbourne, and at about the same $1.5 million price the two produce very different gross income, sit under different building and rooming house rules, and ask different things of whoever manages them.

Neither is the right answer for everyone.

Overview

At the same price, a standard rental earns one rent and a nine-bed earns nine. That gap is real, and it comes with more rules, more management and a minimum capital position. Gross figures are compared here; your net result depends on your loan structure, deposit and tax position.

The two side by side

Feature Traditional rental Purpose-built nine-bed co-living
Price point About $1.5 million $1,574,000 base project cost ($1,650,250 including additional considerations)
Leases on the title One household, one lease Nine residents, each on their own lease
Weekly rent Around $865 for the whole house Around $380 a room, about $3,442 across nine rooms
Gross annual rent $45,000 $179,010
Gross yield 3% 11.36%, based on recent acquisitions
Building classification Usually Class 1a, a single dwelling Class 1b, confirmed before commitment
Victorian rooming house rules Do not apply to a single household Operator licensing, council registration and minimum standards
Management One tenancy Nine tenancies, run by a specialist co-living manager
One vacancy means No rent until it is re-let One room of nine without rent
Average figures based on most recent projects.

Income: one rent or nine

The difference in gross income comes from the number of leases. A traditional rental is let to one household on one agreement, so its rent is capped by what one household will pay. A purpose-built nine-bed is one dwelling of nine rooms, nine bathrooms, single storey, with shared living space. Nine people live in it, each on their own lease, and you own the whole building on one title.

Average figures based on most recent projects: the nine-bed rents at around $380 a room a week, about $3,442 a week across the building, for $179,010 a year in gross rental income. The $380 is rounded; the actual average is $382.50 a room, and $382.50 x 9 rooms x 52 weeks = $179,010. The base project cost is $1,574,000. On that cost, the gross yield is 11.36%, based on recent acquisitions.

The traditional rental in the same comparison costs about the same $1.5 million and rents for around $865 a week in total, or $45,000 a year, a 3% gross yield. Average figures based on most recent projects.

There is also a longer record to look at. 10.8% is the historical average gross yield across The Harmony Group’s delivered projects. It measures finished buildings over time, so keep it separate from the recent-acquisitions figure, and treat neither as a forecast for a building you have not bought yet.

  • Compare gross with gross. A yield on one property and a net figure on the other is not a comparison.
  • Check which cost each yield was divided by.
  • Ask how many leases sit on the title before you look at the yield.

What the gross figures leave out

Both properties carry the costs Moneysmart lists for any investment property: council and water rates, building and landlord insurance, land tax, property management fees, and repairs and maintenance, with loan repayments on top. Moneysmart’s advice is to do a budget comparing expected income with outgoings, and not to rely on rental income alone to cover the mortgage. That applies to both columns of the table.

The nine-bed adds costs a single-household rental does not have. Consumer Affairs Victoria describes a rooming house as a building where four or more people can live in rented rooms, usually on separate agreements with the operator, and the operator carries extra obligations. Consumer Affairs Victoria requires gas and electrical safety checks every two years, and since 13 October 2026 operators have had to keep records showing the property meets the rooming house minimum standards. A specialist co-living manager also does more work than an agent managing one lease.

So the gross gap in the table is the start of the comparison, not the end of it. The net position depends on your loan structure, deposit and tax position. Put both columns in front of your accountant and mortgage broker with your own figures, and compare what each leaves you after costs. The gross-to-net picture for any rental is set out in what a positive-geared property is, and how to find one.

Rules and the building itself

A traditional rental is usually a Class 1a building under the National Construction Code: a single dwelling, such as a detached house or a townhouse. The Australian Building Codes Board describes a Class 1b building as a small shared residential building with a floor area under 300 square metres that ordinarily has fewer than 12 people living in it. Harmony’s nine-bed is purpose-built for that classification, and Class 1b certification is confirmed before commitment.

Victoria then adds its rooming house layer. Operators must be licensed under the Rooming House Operators Act 2016, a scheme in force since 26 April 2017, and the rooming house must be registered with the local council. Consumer Affairs Victoria notes that a rooming house is different from a share house, where everyone signs the same agreement. In a rooming house, residents usually have separate agreements with the operator.

This is where the comparison can go wrong for an investor. A standard house let room by room to unrelated people, without the building being certified for that use, can look like a nine-bed on a rent appraisal and carry a very different legal and insurance position. Harmony builds purpose-built co-living only. The difference is explained in purpose-built co-living versus a rooming house and purpose-built co-living versus HMO conversions.

Classification is a building and safety question. It does not settle anything about tax, so keep certification out of any conversation about deductions.

Management and vacancy

Moneysmart names vacancy as a core risk of any investment property: there may be times you cover the costs yourself because there is no tenant. The two structures carry that risk differently. When a traditional rental is empty, all of its rent stops. When one room of a nine-bed is empty, one ninth of the rent roll stops and the other eight leases carry on.

The trade is workload. Nine leases mean nine sets of enquiries, inspections and renewals, and a building that has to meet rooming house standards room by room. The nine-bed is run by a specialist property manager. As at October 2026, our property management partners manage 477 rooms with only 6 vacant at any time, a 1.26% vacancy rate, and maintain 98%+ occupancy. That is their record across a portfolio of rooms, not a promise for any single building.

Rent level is part of the same picture. On three years of the team’s own tenant data, Harmony’s nine-bed rooms rent for $100 or more per room per week above the co-living market average. That is a historical comparison, not a forecast.

  • Traditional rental: fewer moving parts, and a vacancy stops all the rent.
  • Nine-bed: more moving parts, and a vacancy stops one room’s rent.
  • Either way, ask who manages it and what their occupancy record is across the rooms or homes they run.

Simplicity, specialisation and fees

Moneysmart lists, among the benefits of property, that you need no particular specialised knowledge to invest in it. That holds for a traditional rental. A nine-bed is a specialised product: site selection, certification, building to the rooming house standards and room-by-room management all need people who do this work every week.

That is the reason to check the specialist as closely as the building. Harmony chooses sites with the 118-point method, which covers 42 points of market analysis, 38 of area selection and 38 of property specification, and rejects 85% of the opportunities it evaluates. Clients pay Harmony $0. Builders pay Harmony’s fee at settlement at one flat rate across the panel, so the fee does not reward steering you to a particular builder. The team brings 15+ years of specialist accommodation experience. How these pieces fit together is set out in The Harmony Formula, and how to test any specialist in how to vet a high-yield property investment specialist.

Moneysmart also notes that you cannot sell off a bedroom if you need cash in a hurry. That is true of both structures. A nine-bed is one building on one title, so treat it as a single, whole investment.

Which one suits you

A traditional rental suits you if you want one tenancy, the standard set of rules, and a property you can understand without a specialist. It also suits you if you do not have $600,000 available, because Harmony’s co-living investment requires a minimum of $600,000 in cash, usable equity, or a combination of both.

A purpose-built nine-bed suits you if you have that capital, you want gross income built from nine leases, and you are comfortable owning a building that runs under rooming house rules with a specialist manager. We build in Melbourne. Our investors come from every state, and buying from interstate works remotely.

If you are still deciding between co-living and other higher-income strategies altogether, the wider comparison is in co-living versus other high-yield property strategies.

Frequently asked questions: co-living versus a standard rental

Q: How much more gross rent does a nine-bed earn than a standard rental at the same price?

Average figures based on most recent projects: a standard investment property at the same $1.5 million price rents for around $865 a week, or $45,000 a year. A nine-bed at around $380 a room earns $179,010 a year in gross rent. These are gross figures. Your net result depends on your loan structure, deposit and tax position.

Q: Is a nine-bed co-living property riskier than a normal rental?

It carries different risks. It runs under rooming house rules, needs Class 1b certification and specialist management, and needs at least $600,000 in cash, usable equity or both. Its vacancy risk is spread across nine leases instead of one. A traditional rental is simpler, and a single vacancy stops all of its rent. Which risks you would rather carry is a question for you and your licensed adviser.

Q: Can I just rent the rooms of an ordinary house separately?

Consumer Affairs Victoria describes a rooming house as a building where four or more people can live in rented rooms, usually on separate agreements with the operator. Rooming houses come with operator licensing, council registration and minimum standards. A house that was never certified for that use carries a different legal and insurance position from a building designed and certified for it. Harmony builds purpose-built co-living only, with Class 1b certification confirmed before commitment.

Q: How do I start comparing the two properly?

Start with the free co-living education program, which explains how a nine-bed’s numbers are built and how the building is designed and run. Then take the gross figures for both options to your accountant and mortgage broker. Finish any 9 modules and a booking link opens for a one on one with one of our directors.

Learn how a nine-bed works before you compare

The free co-living education program shows how room-by-room income is built, what sits between gross and net, and how a purpose-built nine-bed is certified and managed. Its core takes about 45 minutes. If co-living isn’t suitable for you, we’ll tell you why.
