Does this deal stack up?

PropDEV is a smart assisted property development feasibility platform. Give it the deal basics — purchase price, site area, yield, sale price, build quality — and it produces a professional-grade feasibility study: cost, profit, margin, ROE, break-even, maximum supportable land price, and the next checks you need to run.

Indicative feasibility only. PropDEV gives you fast, transparent estimates from a rate library — not financial, legal, tax, or planning advice. Verify every assumption with your accountant, lawyer, town planner, QS, lender, and builder before relying on any number here.

Deal basics

Enter the essentials. Everything else is assumed from our NSW rate library — you can drill in once the headline looks right.

Separate from contingency. Contingency = unknowns you haven't priced; overrun = things you HAVE priced that slip anyway (weather, scope creep, late deliveries, prices moving between estimate and order).

Here's how the numbers were built

Updates live as you edit

Revenue

  • Revenue of $9,600,000 comes from 4 dwellings selling at an average of $2,400,000 each.

Construction cost

  • Construction lands at $2,679,600 — 880 m² of gross floor area × $3,045/m².
  • That rate is a Sydney metro standard townhouse build on a normal site (rate library, medium confidence). Plausible range: $2,600/m² – $3,630/m².

Acquisition

  • Land acquisition totals $2,106,512 — the $2,000,000 purchase plus $106,512 of NSW stamp duty, legal, due diligence, and settlement adjustments.
  • Stamp duty alone runs against the current Revenue NSW schedule (1 July 2025 – 30 June 2026). The thresholds re-index every July.

Soft costs, finance & contingency

  • Planning & design — architect, engineers, planners, certifier, plus council/authority contributions — adds $299,572. Contributions vary wildly by council; this line carries low confidence and should be verified.
  • Project management, QS, insurance, and other professional fees add $107,184. Marketing, sales commission, and legal on sale add $332,400.
  • Finance — interest plus establishment and line fees — adds $414,782 at an indicative 9.5% rate and 65% loan-to-cost. Replace with a real lender quote before relying on this.
  • Holding costs — rates, NSW land tax, utilities while you develop — add $55,000 over the project life.
  • Contingency of $341,876 reflects the early feasibility stage. Earlier stages carry more contingency because more is unknown — it shrinks as the project matures and the builder quotes harden.

The bottom line

  • Total development cost is $6,503,740. Against revenue of $9,600,000, the deal yields $3,096,260 of profit — a 47.6% margin on cost.
  • That's 29.6% above your 18% target — the deal meets your benchmark.
  • Required equity is $2,217,924 with peak debt of $4,119,001 (simplified — a cash-flow-driven peak comes in the next phase). Return on equity comes in at 139.6%.

What would change the answer

  • Break-even sale price is $1,625,935 per dwelling — sale prices can drop by 32.3% before the deal loses money.
  • At your 18% target margin, the maximum supportable land price is $3,738,366 — $1,738,366 of headroom above the $2,000,000 you're paying.

What scale does this site need?

Target: 18.0% margin on cost

You're proposing 4 dwellings × 220 m² (880 m² total GFA) → 47.6% margin on cost.

Minimum to hit your 18.0% target on this site: 2 dwellings × 100 m² (200 m² total GFA at 40.4%). Your current configuration has 29.6% of headroom above target.

Indicative feasibility only. Not financial, legal, tax, or planning advice. Verify all assumptions with your professional advisers before relying on any number here.

What's behind the numbers

Transparency by default. Every assumption traces to a published source or an indicative range — and you can override anything.

  • NSW transfer (stamp) duty. Schedule for 1 July 2025 – 30 June 2026, sourced from Revenue NSW. CPI-indexed annually under Duties Act 1997, Chapter 2 Part 3 Div 3. Source ↗
  • Construction $/m² rates. Sydney metro 2025–26 rates, triangulated from published construction cost guides (Rawlinsons, Altus Group, Rider Levett Bucknall) and indicative builder-rate ranges. Replace with a real builder quote for higher confidence.
  • Council & infrastructure contributions. NSW councils set contributions independently under s7.11 / s7.12. The figure shown is a wide indicative range only — verify with the relevant council or a town planner before purchase.
  • Finance rates & terms. Indicative bands for typical Australian residential development finance as of late 2025 / early 2026. Real rates depend on lender, leverage, presales, security, and project risk — always replace with a lender quote before committing.

Disclaimer

PropDEV is a feasibility-modelling tool by Varloch Studio. The numbers it produces are indicative estimates based on user-entered inputs and assumed rates from a rate library that is updated periodically. PropDEV does not provide financial, legal, tax, planning, valuation, or construction advice, and its output should not be used as a substitute for professional advice from a qualified accountant, lawyer, town planner, quantity surveyor, valuer, lender, or builder. Stamp duty, council contributions, GST treatment, finance terms, and construction rates change frequently and vary by location, lender, council, and project — every figure in a report must be verified independently before any acquisition, finance, or planning decision is made. Use at your own risk.
