The best development sites in Melbourne rarely appear on Domain or realestate.com.au. Developers who rely on public listings compete with every other developer in the market, paying retail price for sites with known development potential already priced in. The serious money is made in off-market, where motivated vendors, estate sales, deceased estates and portfolio disposals create below-market opportunities. This guide explains exactly how to find them.
Why Off-Market Development Sites Are Better
| Factor | On-Market Site | Off-Market Site |
|---|---|---|
| Competition | 10-30+ competing offers | 1-3 buyers at most |
| Price | Retail + development premium | Market or below |
| Due diligence time | 7-21 days (vendor’s timeline) | Negotiated (weeks) |
| Vendor motivation | Maximising price | Often speed, privacy or simplicity |
Where to Find Off-Market Development Sites
- Direct approaches to owners of large lots in RGZ and GRZ zones
- Estate agents who specialise in deceased estate and estate sales
- Receivers and insolvency practitioners managing distressed assets
- Direct mail campaigns to owners of corner lots in target suburbs
- Off-market property portals like the Collings Off-Market Portal
- Building and planning permit databases (sites with permits already approved are the most valuable)
