Your rent was not set by a landlord in a back room with a calculator. It was shaped by layers of software that started with Google Maps and ended with a rent-bot.

The entry point is deceptively simple. Zoom in on satellite maps, filter for lots over 800 m², cross-check with zoning maps to see where density bonuses apply. The target list is clear: long-held land in the right postcode. The tactic is simple: sign a put/call option. No need to buy the property outright. Control it on paper with minimal cash down.

Once a planning approval looks likely, flip the option, pocketing a windfall in days or weeks. In Queensland, put/call option deeds are common, while sunset clauses have been criticised for allowing contracts to be cancelled then resold at higher prices.
