What it costs to build a build to rent development in Australia

Institutional build to rent apartments cost roughly $4,300 to $7,000 per square metre to build in Australia in 2026, land and amenity extra, while smaller townhouse or house BTR runs the same $2,900 to $4,500 per square metre as build-to-sell. A 50-unit Brisbane mid-rise worked example lands near $28.3 million all-in, yielding about 4.5% on cost.

Build to rent is a different financial animal from a normal apartment or townhouse project. The developer does not sell anything, so there are no presales to de-risk the debt and no exit at settlement. The asset is built, leased up and either held or sold as a single going concern on a capitalised income basis, which is why the federal government and three states now run a parallel set of tax rules for it. The figures below come from the ATO's own BTR concession pages, state revenue offices, JLL and Feasly research and named 2025 and 2026 BTR projects, with a worked example for a 50-unit Brisbane mid-rise.

What institutional BTR apartments cost to build

BTR apartments are built to the same trade rates as any other apartment block, at $3,700 to $7,000 per square metre of gross floor area for a building with a lift, but BTR product sits at the middle to top of that band because operators add shared amenity that a build-to-sell block skips: a resident lounge, coworking room, gym, rooftop terrace, parcel locker room and often a pool, all of which need fitting out and then staffing. On a like-for-like basis, budget $4,300 to $7,000 per square metre for the base building and add a separate allowance of $10,000 to $20,000 per apartment for the communal amenity fit-out on top.

The South Yarra figure is a useful ceiling, not a benchmark: it is a premium inner-Melbourne site with full retail podium and two towers. A middle-ring or growth-corridor mid-rise on a standalone site, without a commercial podium, lands well under that per-unit figure, which is what the worked example below shows.

The smaller build: townhouse and house BTR for private developers

Below the 50-dwelling threshold that unlocks the federal and state BTR concessions, a growing number of private developers are building 6 to 30 townhouses or houses and renting the whole project out themselves instead of selling each dwelling under a strata plan. The build cost is the same as build-to-sell townhouses, $2,900 to $4,500 per square metre ex GST, because it is the same trade, the same slab, frame and roof. What changes is the exit: there is no presale contract of sale to settle, no strata subdivision, and none of the GST margin scheme mechanics that apply to a sale. Feasly and industry commentary link the growth in this segment to NSW's Low and Mid-Rise Housing SEPP and Victoria's density uplift reforms, which now let three to twenty dwellings go up on a consolidated residential lot without the DA risk of a full apartment scheme.

The trade-off is concessions. A 20-townhouse BTR project sits well under the 50-dwelling threshold, so it gets none of the 15% MIT withholding rate, none of the 4% capital works deduction, and none of the state land tax discounts covered below. It is financed and taxed like any other held residential investment portfolio, just built in one go rather than bought one house at a time. The appeal for a private developer is diversification away from presale risk on a small site and a rental income stream once complete, not a concessional tax structure.

The federal tax settings that make BTR different

From 1 July 2024 an eligible BTR development gets two federal concessions that do not exist for any other residential asset class. The withholding tax rate that a managed investment trust pays on eligible fund payments from the development drops from 30% to 15%, and the capital works deduction rate on the building rises from 2.5% to 4% a year, which shortens the write-off period from 40 years to 25. Both only apply where construction commenced after 7:30pm AEDT on 9 May 2023.

Access is conditional, not automatic. The development needs at least 50 self-contained dwellings (40 in Western Australia), held by a single entity for a continuous 15-year compliance period. At least 10% of the dwellings must be offered as affordable housing to eligible tenants at no more than 74.9% of market rent, and every tenant, not just the affordable cohort, must be offered a lease term of at least 5 years, though a tenant can ask for something shorter. Miss any condition during the 15 years and the ATO can apply a misuse tax that claws the benefit back. This is a federal income tax and withholding structure, separate from the state land tax concessions below, and both need to be checked against the specific project before a return is modelled.

State land tax concessions: NSW, VIC and QLD

Land tax is the other lever, and it runs on top of the federal concessions, not instead of them. NSW, Victoria, Queensland and South Australia each cut the taxable land value for an eligible BTR development by 50%, and give an exemption or refund of the foreign purchaser and absentee owner land tax surcharge. The states differ on how long the discount runs and what strings are attached.

Every one of these is an ongoing test, not a one-off approval. A lender or investor pricing a BTR asset checks the compliance mechanics as closely as the cost plan, because losing the concession partway through the hold changes the numbers behind the valuation.

What yield BTR needs to stack up

JLL's build to rent research for the Sydney market puts developments at a target gross yield of 3.5% to 4.5% and an exit capitalisation rate of 4.0% to 5.0%, with development margins (the gap between total development cost and the capitalised value on completion) of 12% to 18% where the numbers work. Feasly's own indicative example above shows the mechanics: a 5.45% yield on cost sold at a 4.5% cap rate produces a 20% margin, because yield on cost has to sit meaningfully above the exit cap rate before there is any margin in it at all. If the exit cap rate creeps up to match or beat the yield on cost, the margin disappears or goes negative, which is the single biggest risk in a BTR feasibility.

On the income side, operators budget operating costs at roughly 30% to 35% of effective gross income once the land tax discount is applied, covering management, on-site staff for the amenity, insurance, council rates, repairs and marketing, well above the 20% to 25% a landlord pays on a single rented house because BTR runs a hotel-style service layer the tenant does not pay for directly. Lease-up itself, filling 50 or more apartments to a stabilised occupancy most operators put at 95% or higher, typically takes 6 to 12 months from practical completion, and that period carries full holding costs against partial income, which is the gap the worked example below prices.

Worked example: a 50-unit build to rent apartment building in Brisbane

The figures below are indicative and assembled from the sources above: a 2,400 square metre middle-ring Brisbane site, a mid-rise of 3,600 square metres gross floor area across 50 apartments (studio to two-bedroom, averaging 72 m2 GFA per unit including shared amenity), built at $4,300 per square metre, a 20-month construction programme and a 6-month lease-up before refinance. All costs are ex GST with the developer registered and claiming input credits.

Stabilised income: average rent of $735 a week across the 50 units is $1,911,000 gross potential a year. Allow 3% for vacancy and bad debt for effective gross income of $1,853,670, and operating costs at 32% of that leaves a stabilised net operating income of about $1,260,000, a yield on cost of 4.5%, in line with JLL's 3.5% to 4.5% band. At a 4.25% exit cap rate the asset is worth about $29,650,000, a margin of only 4.9% on cost. Sensitivity is the whole story here: at a 4.0% cap rate, near the tight end of JLL's range, the value rises to $31,500,000 and the margin to 11.4%; at 4.75% the value falls to $26,526,000 and the project runs at a 6.2% loss; at 5.0% it loses 10.9%. A townhouse or house BTR project of 20 to 30 dwellings runs the same arithmetic at a smaller scale, just without the federal and state concessions built into the income line.

How a build to rent development is funded

No presales means a BTR construction loan cannot be sized the way a normal apartment facility is, against a book of signed contracts. Lenders size the facility against the total development cost during the build and against the stabilised, capitalised valuation once leased, and they underwrite the lease-up period as carefully as the build programme, often with an interest reserve to cover the months between practical completion and stabilised occupancy.

Bank construction debt for BTR runs 55 to 65% of total development cost at roughly 6.5 to 7.5% p.a. and wants a strong sponsor with a demonstrated leasing platform. Non-bank senior lenders fund 65 to 75% of cost at around 8 to 11% p.a. with more flexibility on scale and no presale condition. Private first mortgage lenders can reach 80% of cost at 10.5 to 14% p.a. on smaller townhouse or house BTR projects under the 50-dwelling threshold. The other funding route unique to this asset class is forward funding: an institution such as a super fund or a listed trust commits to buy the completed, tenanted asset on a fixed cap rate before construction starts, funding the build in progressive drawdowns against that price, which removes leasing and valuation risk from the developer entirely and is how much of the 50,000-plus unit national BTR pipeline gets built.

On stabilisation the facility is refinanced to a term investment loan at 55 to 65% of the completed valuation, typically from about 6.0% p.a. Because term LVR usually sits below the construction facility's LVR, most refinances need a top-up of equity to fully retire the construction debt, which is worth pricing in from day one. Land held before approvals can be geared under commercial property finance or property finance, and the build itself sits under construction finance. Private lending is typically business purpose and not consumer regulated, and every facility is subject to lender assessment.
