How We Invest.

The Greenfield Convergence Investment Methodology - how we identify the next corridor, score every market against six principles, and manufacture day-one equity through builder-direct wholesale acquisitions.

✦ Greenfield Convergence Investment Methodology (GCIM)

We Get In Before the Cranes Arrive

Greenfield investing is the single highest-leverage play in Australian residential property - buying into growth corridors before the infrastructure lands, not after. This is the methodology we've compounded across three cycles: Perth 2023, Brisbane 2023–2025, and now Melbourne 2026.

Cycle 1 · Called Early

Perth WA - 2023

Positioned clients into Mandurah / Lakelands / Baldivis corridors before the Perth boom repriced the market +30–40% over 24 months. Mandurah alone ran +18% pa.

Cycle 2 · Doubled Down

Brisbane QLD - 2023–25

Loaded into Moreton Bay, Logan and Ipswich corridors ahead of the 2032 Olympics capex wave. South Maclean, Ripley and Deebing Heights now running +10–13% pa, with flagship deals above +37%.

Cycle 3 · Active Now

Melbourne VIC - 2026

Wyndham, Whittlesea and Geelong corridors sit 18–24 months behind Brisbane on the cycle. Land values bottoming, infrastructure committed, yields improving. The entry window is open right now.

🌱

The Greenfield Thesis

You don't buy a suburb - you buy a stage of a cycle. Greenfield entry means raw land + new build in corridors where roads, schools, shops and rail are pipelined but not yet delivered. Every infrastructure dollar that lands after settlement reprices your median upward. You bought the empty paddock; the city arrived around it.

The Corridor Rotation

Capital rotates between capital-city corridors on a 24–36 month lag. Perth ran first. Brisbane followed. Melbourne is next. We map the rotation using infrastructure capex, population inflow, vacancy and yield compression - and we move clients into the next corridor while the last one is still printing equity.

🏗️

Infrastructure Lead Indicators

Funded road & rail, zoned school catchments, hospital ground-breaks, commercial node approvals, NBN / water / power schedules. When 3+ indicators trigger on a corridor, it enters the active buy list. This is how we were 12 months ahead in South Maclean - comps caught up after our clients held contracts.

🤝

Pre-Release Builder Allocation

We hold direct allocation with Tier-1 builders and master-planned developers in each corridor. That means pre-release stock 3–6 months before display villages open - at cost-plus pricing. By the time stage 1 settles, identical blocks are typically listed 15–25% higher.

📊

RP Data + Bank Val Verification

Every corridor call is stress-tested against live RP Data / Cotality comparables and independent bank "as-if-complete" valuations (NAB / CBA / Tier-1 lender panel). If the valuer doesn't confirm the spread on the exact builder and configuration, the deal doesn't leave the desk.

📈

Corridor-to-Corridor Compounding

Perth equity → refinance → Brisbane. Brisbane equity → refinance → Melbourne. This is how a single-property investor becomes a 4–5 property portfolio in 36 months - leverage + corridor rotation, compounded. Avg ~130% cash-on-cash across the book proves the mechanism works.

✦ Greenfield Convergence Investment Methodology (GCIM) · The Six Principles

How we grade every corridor.

Every market in our portfolio is scored against six principles before it enters the buy list. Minimum 48 out of 60 to qualify as Tier-1. This is the framework - it keeps us disciplined across states and across cycles.

PRINCIPLE 01

Affordability Convergence Gap

The corridor must trade 30–50% below its capital-city median - the historical "sweet spot" for convergence trades. Too narrow means no upside. Too wide means broken fundamentals.

PRINCIPLE 02

Construction Economics Alignment

Wholesale build price must sit materially below retail replacement cost. Rising civil and labour costs create an embedded price floor. We target 20%+ manufactured equity at contract.

PRINCIPLE 03

Infrastructure Catalyst Framework

Rail, road, retail, schools, hospital, jobs - funded or committed within a defined minute radius. A corridor needs 3+ indicators already triggering to enter the buy list.

PRINCIPLE 04

Demographic Acceleration

Population growth above 3% p.a., owner-occupier rate above 70%, median age under 35. Young, family-forming demographics create structural rental demand and long hold psychology.

PRINCIPLE 05

New-Build Advantage

7-star NatHERS minimum, full Division 43 and Division 40 depreciation, 10-year structural warranty, zero immediate maintenance. Wholesale build = tomorrow's replacement-cost floor.

PRINCIPLE 06

Convergence Risk Framework

Rate sensitivity, supply absorption runway, demand depth through cycles. Tier-1 corridors carry low-to-moderate risk even in adverse macro. Our worst downside is compressed upside.

✦ The Wholesale Mechanic

Manufactured equity, day one.

Raw farmland → civil works → developer margin → our rebate → your contract. The gap between what you pay and what it would cost to build at retail is the manufactured equity - locked in the day you sign. Every infrastructure dollar that lands after settlement compounds on top.

Raw farmland (pre-zoning) cost stack starts

Civil works · roads · services · utilities + developer input

Developer margin + margin

Retail sticker land price full retail

Realtyex wholesale rebate we remove this

Wholesale build (Tier-1 builder) cost-plus pricing

Your contract price wholesale total

Retail replacement cost · equivalent build open market

Embedded equity at contract ~20%+ day one

Our clients routinely settle at 15–25% below retail replacement cost - the delta between what a developer charges us wholesale and what the same stock lists for 3–6 months later.

The mechanic works the same in every state. We transact at developer cost-plus; the retail market reprices after. Every bank "as-if-complete" valuation has to confirm the spread before we release the deal to the client.
