Rooming house investment risks: an honest guide

Why the returns are higher

A rooming house leases each room separately. On the same suburban block, nine rents add up to far more than one household’s rent. Across our 21 current projects, rent is $330 to $400 per room each week, and projected gross yields run from 10.7% to 14.5%.

That higher yield isn’t free money. You’re running a small accommodation business, not a single tenancy. Nine tenants means more turnover, more wear and more rules. The rest of this guide is about those costs and risks, so you can judge whether the trade-off suits you.

Regulation and compliance

A standard rental answers to tenancy law. A rooming house in Victoria answers to four layers of rules, and each one can stop you renting rooms if it isn’t in place:

• Planning. Clause 52.23 of the planning scheme lets a rooming house of up to 300 m², 12 residents and 9 bedrooms go ahead in most residential zones without a planning permit, if every condition is met.
• Building. It must be approved as a Class 1b building under the National Construction Code, not a family home with locks on the doors.
• Council registration. It must be registered with the local council under the Public Health and Wellbeing Act 2008.
• Operator licence. Whoever operates it must hold a rooming house operator licence from Consumer Affairs Victoria.

Then there are the minimum standards residents are entitled to, and they keep changing. The current standards come from the Residential Tenancies (Rooming House Standards) Regulations 2023. Since 1 December 2025, every resident’s room must have a fixed heater. From 1 December 2030, that heater must be an energy-efficient type. Power outlets and circuit breakers must be checked by a licensed electrician every two years.

The classic trap is a converted house. Whitehorse City Council warns that converting a building from Class 1a to Class 1b without approval “may constitute an offence which can be prosecuted by Council or the police.” If you’re looking at an existing rooming house, ask for the building permit that shows it was approved as Class 1b.

Vacancy and tenants

Vacancy works differently in a rooming house. When a standard rental sits empty, the rent drops to zero. When one of nine rooms is empty, you lose about 11% of the rent. That’s the upside.

The downside is that rooms turn over more often than family homes, and every change means advertising, screening, a new agreement and some cleaning. How much that hurts depends on how long rooms stay empty. Here’s what it does to cash flow on our Noble Park project, where each room rents for $380 a week:

Noble Park feasibility: $380 per room per week, running costs of $17,640 a year plus 10% management, and an 7.5% interest-only loan of $1,242,616. Before land tax and income tax.

Residents are protected by the Residential Tenancies Act 1997. They have rights around entry, house rules, bonds and repairs, and disputes go to Rental Dispute Resolution Victoria or VCAT. Good screening and a manager who knows rooming house law matter more here than in a standard rental.

Running costs

In most rooming houses the owner pays the power, water and internet, because rent is charged per room with bills included. Those costs add up. In our Noble Park feasibility, running costs are $35,424 a year, about 20% of the gross rent:

Land tax isn’t included. See the land tax section below.

If energy prices rise, your costs rise with them, and you can’t always pass that straight on to residents. Solar, heat-pump hot water and a high energy rating reduce this risk. Our homes are built to a 7-star energy rating with a 10 kW solar system for exactly this reason.

Finance and interest rates

Fewer lenders finance rooming houses than standard homes, and construction loans work differently from a normal mortgage. Some lenders will want a bigger deposit or assess the income differently. Talk to a broker who has financed Class 1b builds before, early.

Interest is usually the biggest single cost. On the Noble Park loan of $1,242,616, every 1% rise in the interest rate costs about $12,426 a year. At 8.5% instead of 7.5%, cash flow falls from $49,220 to $36,794. Add one room empty all year as well, and it falls to $19,010.

Before you commit, run the numbers at a higher rate and with rooms empty, and make sure you could carry the property if both happened at once.

Valuation and resale

Our feasibilities include an estimated value on completion, from $1.9 million to $2.3 million across current projects. That’s an estimate, not a bank valuation. A lender’s valuer may see it differently, and a lower valuation means a smaller loan or a bigger deposit.

When you sell, your buyers are mostly other investors. A family looking for a home is unlikely to want nine ensuite suites and a commercial-sized laundry. The whole property sits on one title, so you can’t sell rooms off one at a time. Plan to hold for the long term, and don’t count on a quick sale if your circumstances change.

Construction

If you’re building new, you carry construction risk: delays, cost increases and, at worst, a builder that fails. Our current projects use a base build contract of $790,000, but site costs vary. Noble Park includes $20,000 for demolition and site preparation, while some vacant blocks need none.

Check the builder is registered with the Building and Plumbing Commission, which replaced the Victorian Building Authority on 1 July 2025. Read what the contract includes and excludes, how progress payments work, and what happens if the build runs late. Our timeline from land settlement to first rent is typically 8 to 12 months, and it varies by site and council.

Land tax and income tax

Land tax is charged on the site value of land you own, across all your holdings, not just this one. At the general rates, land with a taxable value of $670,000 would attract about $2,670 a year if it were the only land you held. Trusts, companies and foreign owners pay different rates.

Victoria has a land tax exemption for registered rooming houses, but the conditions are strict. The rooming house must be registered with the council, at least 80% occupied by long-term residents in the previous year, and charge no more than a maximum tariff, which is $412.55 per person per week for single, lodging-only rooms in 2026. The State Revenue Office also requires at least one room, “excluding self-contained units or apartments”, for four or more residents. Don’t assume you qualify. Check with the SRO or your tax adviser.

The cash flow figures in our feasibilities are before land tax and income tax.

Putting a lot into one asset

A rooming house is a large single purchase. Our current projects total $1.13 million to $1.61 million each, including land. For many investors that’s most of their borrowing capacity in one property, in one suburb, with one type of tenant. That concentration is a risk in its own right, and worth discussing with your financial adviser.

Checklist before you commit

• Is the building approved as Class 1b, with a building permit to prove it?
• Does the site meet every condition of Clause 52.23, or does it need a planning permit?
• Will the rooming house be registered with the council before residents move in?
• Who will be the licensed operator? Look them up on Consumer Affairs Victoria’s public register.
• Does the design meet the current minimum standards, including the 2030 heating upgrade?
• Is the builder registered with the Building and Plumbing Commission, and is the contract fixed-price?
• Have you run the cash flow with the interest rate 1 to 2% higher and one or two rooms empty?
• Have you spoken to a broker who has financed Class 1b builds, and what did the valuation say?
• Have you checked your land tax, and whether any exemption could apply?
• Have you had independent financial, tax and legal advice?

Questions

Are rooming houses a good investment?

They can be, for the right investor. The yields are much higher than a standard rental, and one empty room doesn’t wipe out your income. In return, you take on more regulation, more management, running costs and a narrower resale market. They suit investors who want income, plan to hold long term and have a buffer for vacancies and rate rises.

Can the rules change after I’ve built?

Yes. Victoria updated its rooming house minimum standards in 2023, added a fixed-heater requirement from 1 December 2025, and requires energy-efficient heaters from 1 December 2030. Build to the current standards, and budget for upgrades over time.

What happens if a resident stops paying?

Rooming house residents are covered by the Residential Tenancies Act 1997, so there’s a set legal process for rent arrears and notices, with disputes going to Rental Dispute Resolution Victoria or VCAT. A manager who knows rooming house law will follow it for you. With nine separate rooms, one resident in arrears affects a ninth of your income, not all of it.

Is a rooming house harder to sell than a normal house?

Usually, yes. Most buyers are investors rather than owner-occupiers, and the property is sold as a whole on one title. Treat it as a long-term hold.
