The hidden constraints that turn a “great buy” into an expensive mistake — and how to spot every one of them before you sign. Written by the planners who see the aftermath.
The pattern we see every week
The buyer assumed the property could do something, and the planning controls said otherwise. The information was available the whole time. Nobody checked it, because nobody knew to.

Inside the guide
Every flag comes with the test that finds it
Each of the ten is a page of its own: what the constraint actually does, why buyers miss it, and a “spot it” box telling you exactly which map, certificate or register to check in your state.
Drainage easements, sewer mains and rights of way regularly run through the exact part of the block a buyer planned to build on. Building over or near them is restricted, sometimes prohibited.
Spot itRead the title plan, not just the title. Then overlay the easements against where your pool, granny flat or extension would actually sit.
