Melbourne dwelling values are down 4.7 per cent over the year to 31 August 2026 on Cotality’s index, while SQM Research’s advertised rents were up 6.0 per cent over the year to mid-August 2026. That is a market fact, not an instruction to act. Together, the two movements lower the cost of the block and strengthen the income case for whatever gets built on it.

If you own, or are looking at, an established block in Melbourne and are trying to work out whether falling values and rising rents together add up to an opening or a trap, that is a reasonable question to sit with. Headlines about falling values read like a warning. Headlines about rising rents read like an opportunity. Reading both about the same city at the same time understandably makes people cautious rather than confident.

A knock-down-rebuild does not become a good move purely because the block is cheaper this year than last. What you build, how it is certified, and how it earns from the day it settles decide whether a softer entry price turns into a genuinely better outcome or a cheaper mistake.

Key Insights

  • Melbourne dwelling values fell 4.7 per cent year-on-year and 1.1 per cent over the month to 31 August 2026, while combined capital city values fell 1.1 per cent over the month (Cotality’s Home Value Index).
  • Melbourne rents rose 6.0 per cent year-on-year to mid-August 2026 and vacancy sat at 1.7 per cent, tighter than the 1.8 per cent recorded a year earlier even as values fell (SQM Research data).
  • A knock-down-rebuild produces a newly built dwelling, but the Government’s own Budget fact sheet defines an eligible new build as one demolished and replaced with a greater number of dwellings, and states that knock-down rebuilds that do not increase supply will not be eligible. Whether nine self-contained suites on one title count as a greater number of dwellings is unresolved: it depends on the final legislation and the reader’s own adviser. Victoria approved 70,570 dwellings in knock-down-rebuild projects between July 2019 and June 2025, second only to New South Wales (Australian Bureau of Statistics).
  • Average figures based on most recent projects show 11.36 per cent on a $1,574,000 base project cost.

What The Melbourne Numbers Actually Show

Two data sets moved in opposite directions in Melbourne through the middle of 2026, and it is worth being precise about both before drawing any conclusion. On the values side, Cotality’s Home Value Index showed combined capital city dwelling values down 1.1 per cent over the month. Melbourne values were down 1.1 per cent over the month and 4.7 per cent over the year to 31 August 2026. Melbourne’s auction clearance rate sat at 55.4 per cent that week, against a combined capital city rate of 53.2 per cent (Property Update’s reporting of the same week’s auction data), pointing to a market where buyers are still transacting but not competing as hard as they were.

On the rental side, SQM Research data reported by Property Investment Professionals showed Melbourne’s combined weekly rent at $695.20 in mid-August 2026, up 6.0 per cent over the year, with vacancy at 1.7 per cent in July, tighter than the 1.8 per cent recorded twelve months earlier. SQM’s own read is that Melbourne is a partial exception to the usual pattern, where falling values and falling rents move together: values softened while the rental market tightened over the same year.

Put the two together and Melbourne is, at the same time, a market where an established block costs less to buy than it did a year ago and a market where a finished dwelling on that block lets into tighter competition for rental stock than a year ago. Those are two separate, verifiable facts.

What A Knock-Down-Rebuild Means For The 2027 Reform

A knock-down-rebuild means demolishing the existing dwelling on a block and constructing a new, purpose-built property in its place. It is demolition and new construction on the same block, always a fresh build, never an adaptation of the existing house.

The reform’s new-build exemption, as announced in the Government’s own Budget fact sheet, applies where an existing property is demolished and replaced with a greater number of dwellings; the fact sheet states plainly that knock-down rebuilds that do not increase supply will not be eligible. Whether nine self-contained suites built on one title count as a greater number of dwellings is unresolved and depends on the final legislation and the reader’s own adviser; our guide to the new-build exemption test sets out the published examples in full.

The 2026-27 Federal Budget narrows negative gearing on established residential property bought after 7:30pm AEST on 12 May 2026, with the change taking effect from 1 July 2027 and still subject to the passage of legislation. New builds are exempt and keep both negative gearing and a choice of capital gains tax treatment. A knock-down-rebuild produces a newly built dwelling, not the original house, but the fact sheet’s own test is a greater number of dwellings on the site, not merely a rebuilt one; whether nine self-contained suites on one title clears that bar is unresolved and depends on the final legislation and the reader’s own adviser.

It is a well-established, well-understood category of construction activity in Victoria. Between July 2019 and June 2025 the state approved 70,570 dwellings as part of knock-down-rebuild projects, the second-highest total of any state after New South Wales, out of a national total of 214,483 dwellings, according to the Australian Bureau of Statistics.

  • Confirm the block’s existing dwelling qualifies for demolition and full reconstruction, not a partial renovation.
  • Check the purchase date against the 7:30pm, 12 May 2026 cut-off if any established property is also involved.
  • Treat the new dwelling’s certification as part of the build decision, not an afterthought.

What The Harmony Formula Does With A Softer Block Price

The Harmony Group works in three stages once the market conditions above are on the table. The team describes the product simply: nine bed, high-end, good location, established area. That is The Harmony Formula, and it sits above two separate pieces of work.

Stage one is location, using the 118-point method. The team assesses 20 to 30 markets a quarter and typically only 4 to 6 pass. In Melbourne’s middle ring, Frankston and a smaller area around Geelong, a nine-bed co-living property can be built without special planning approval. We build in Melbourne. Our investors come from every state, and the process runs remotely.

There is a structural reason the land matters more on a knock-down-rebuild than the house being cleared from it. The Australian Taxation Office’s own guidance on rental property depreciation states plainly that “some assets don’t decline in value, such as land”. Cotality’s Home Value Index measures dwelling values, the combined price of land and structure together, not the land component on its own, so a softer monthly or annual read does not say how much of that movement sits in the block and how much sits in the house being demolished. Once a construction contract is signed, the build cost is fixed and does not move with a monthly index, while the price paid for the block is the part a soft market actually discounts. That is why the two halves of a knock-down-rebuild’s cost move independently, and why the block, not the house due for demolition, is the asset a softer market makes more attractively priced.

Stage two is the build itself, governed by The Build Formula: an exclusive partner network of architects, a builder, hotel fit-out specialists and specialist property managers, working to a set of non-negotiables. Every property is nine rooms, nine bathrooms, single storey, including two executive rooms, built to a seven-year structural guarantee. On the firm’s own three years of tenant data, rooms rent for $100 or more per room per week above the co-living market average. Melbourne builds typically run around six months. Where a block is bought before titles are issued, 87 per cent of clients use an untitled-land strategy that saves $50,000 to $100,000 against retail land pricing and buys time to arrange finance before the co-living lending clock starts.

Certification and design decide whether the finished build justifies its cost, a build-quality question separate from how the property is taxed. It is worth reading what Class 1B certification means for a co-living build before comparing a knock-down-rebuild against holding or selling the existing property.

Stage three is the result. Across The Harmony Group’s delivered projects, the historical average gross yield has been 10.8 per cent, a separate figure from the most recent project set below. Average figures based on most recent projects: weekly rent around $380 a room, $179,010 gross annual rental income, a base project cost of $1,574,000 (project cost including additional considerations of $1,650,250), and a gross yield of 11.36 per cent on the base project cost. The underlying average is $382.50 a room, which across nine rooms and 52 weeks is $179,010, shown rounded to $380.

What This Means For Your Decision, Not Ours

The market data above changes two inputs to the same calculation: the cost of the block you would knock down, and the strength of the rental market the finished build lets into. Whether that combination works for you depends on your own equity, your own timeline and your own tolerance for a build project, not on a headline.

To make the comparison concrete, here is how a nine-bed co-living build compares with a standard investment property at the same purchase price, using average figures based on most recent projects.

Metric Standard investment property (~$1.5m) Nine-bed co-living (The Harmony Formula)
Weekly rent $865 (whole property) around $380 a room, nine rooms
Gross annual rental income $45,000 $179,010
Cost ~$1,500,000 purchase price $1,574,000 base project cost ($1,650,250 including additional considerations)
Gross yield 3 per cent 11.36 per cent on base project cost
Average figures based on most recent projects. Gross figures before costs.

The minimum entry point on a nine-bed project is $600,000 in cash, usable equity, or a combination of both. If that is not where you are, this is not the right move for you right now, and The Harmony Group will say so rather than propose a smaller version of the same idea. The product is the nine-bed build, not a scaled-down alternative.

A softer land market and a tighter rental market do not remove the risks specific to co-living. It is worth reading them honestly, not only the upside: what could go wrong with a co-living investment covers oversupply, management complexity, council compliance and tenant turnover, and how the team works through each one. A knock-down-rebuild also needs its own construction finance, distinct from a standard mortgage, covered in our guide to financing a co-living build in Melbourne.

If you already own the block, or are close to buying one, book a free strategy session and bring the address. The team will tell you honestly whether a knock-down-rebuild nine-bed co-living build suits that site and your position, or whether it does not, rather than fitting the site to the sale.

Frequently Asked Questions About Melbourne Timing And Knock-Down-Rebuilds

Q: Are Melbourne property values actually falling right now?

A: Yes. Cotality’s Home Value Index showed Melbourne dwelling values down 1.1 per cent over the month and 4.7 per cent over the year to 31 August 2026, against a 1.1 per cent monthly fall across the combined capital cities. That is measured, published data, not a forecast, and it can change from one report to the next.

Q: If values are falling, why are Melbourne rents going up?

A: Values and rents measure different things. SQM Research data reported by Property Investment Professionals showed Melbourne’s combined weekly rent at $695.20 in mid-August 2026, up 6.0 per cent over the year, with vacancy at 1.7 per cent, tighter than the 1.8 per cent a year earlier. SQM has described Melbourne as a partial exception to markets where falling values and falling rents move together, because Melbourne’s rental market tightened over the same year that values softened.

Q: Does a knock-down-rebuild count as a new build for the 2027 negative gearing changes?

A: The reform as announced exempts new builds, but the Government’s own Budget fact sheet sets the test as an existing property demolished and replaced with a greater number of dwellings, and states that knock-down rebuilds that do not increase supply will not be eligible. Whether nine self-contained suites on one title count as a greater number of dwellings is unresolved: it depends on the final legislation, which has not yet passed, and on the reader’s own adviser. Our guide to the new-build exemption test sets out the published examples in full.

Q: How much do I need to start a nine-bed co-living project with The Harmony Group?

A: A minimum of $600,000 in cash, usable equity, or a combination of both. Average figures based on most recent projects put the base project cost at $1,574,000, with a project cost including additional considerations of $1,650,250, and a gross yield of 11.36 per cent on the base project cost. If your equity does not reach that floor, the team will tell you honestly rather than proposing a smaller product.

Q: Is now the right time to buy a block for a knock-down-rebuild?

A: Nobody can make that call for you from a headline. What can be answered is what the current Melbourne data shows: values down, rents up, and a knock-down-rebuild producing a newly built dwelling whose status under the 2027 reform’s new-build exemption is unresolved, since the Government’s own test asks whether the site is demolished and replaced with a greater number of dwellings, not merely rebuilt. Whether that combination suits your equity, your timeline and your site is worth a genuine conversation, and the honest answer might be that it is not the right move for you yet.
