6 vs 8 vs 9 Bedroom Rooming House: Which Makes Sense?
6, 8 and 9 rooms are the most common Melbourne rooming-house configurations — but they suit different sites, budgets and risk profiles. Here is how they compare.
In short — 6 vs 8 vs 9 bedroom rooming house: which makes sense?
A 6-room rooming house is a lower-risk, lower-cost entry point that suits standard suburban lots. An 8-room configuration lifts income and suits a mid-sized or double-storey site. A 9-room configuration produces the highest indicative gross yield — commonly 11–13% — but needs a larger or well-shaped block, a stronger design and careful planning. The right choice depends on your site, budget and risk appetite, not on the headline yield.
The three configurations compared
| Metric | 6-room | 8-room | 9-room |
|---|---|---|---|
| Indicative build from | $700k | $880k | $900k |
| Indicative gross rent | ~$140k/yr | ~$187k/yr | ~$210k/yr |
| Indicative gross yield | ~9% | ~10.4% | ~13.1% |
| Typical site | Standard lot | Mid-sized | Larger / well-shaped |
| Risk profile | Lower | Moderate | Higher |
| Planning complexity | Moderate | Higher | Highest |

When 6 rooms makes sense
A 6-room configuration is the most defensible entry point. It suits a standard suburban block, keeps build cost manageable, and still produces a materially higher yield than a single-tenancy rental. For a first-time developer or a tighter budget, 6 rooms is often the right call.
When 8 rooms makes sense
An 8-room configuration lifts income and suits a mid-sized or double-storey site. It carries more planning and construction complexity than 6 rooms but a stronger return. It is the middle ground for an investor with a good block and a moderate risk appetite.
When 9 rooms makes sense
A 9-room configuration produces the highest indicative gross yield but demands the most from the site, the design and the planning process. It suits a larger or well-shaped block, an investor comfortable with active management, and a budget that can absorb a higher build cost. Done well, it is the strongest per-site return.
How to choose
Start with the site, not the yield. A feasibility assessment identifies the room count your block can support at a leasable standard — then the economics confirm whether that count stacks up. Chasing 9 rooms on a block that suits 6 is the most common way investors overcapitalise.
6 vs 8 vs 9 Bedroom Rooming House: Which Makes Sense — FAQs.
Which room count has the highest yield?
Indicatively, a 9-room configuration produces the highest gross yield — commonly 11–13% — because more income is spread across the build cost. But higher yield comes with higher build cost, planning complexity and management intensity.
Is 6 rooms too few to be worthwhile?
No. A 6-room rooming house still produces a materially higher yield than a single-tenancy rental and is the most defensible entry point for a standard block or a first-time developer.
Should I build the maximum rooms my block allows?
Not always. Pushing for the maximum can produce small rooms, weak shared areas and a harder planning outcome. The best result is the room count the site supports naturally at a leasable standard.
Assess your site before you commit.
The fastest way to know what your block can support is a preliminary feasibility assessment — before you purchase land or start construction.
