A REA didn't disclose something he reasonably should have known/found. As part of his duties a prudent REA would have found it and disclosed it as part of their duties in their code of conduct.
It dramatically impacted on the viability of a block because there was a road widening reservation on it which meant 3m along a 40m boundary could not be developed on. Voila 120sqm completely useless on a 788sqm block.
I don't like real estate agents at all... but how could this be the REA fault? Unless someone is looking, isn't this all part of due diligence?
Out of curiousity, for properties in NSW there is a something in the contract that actually tells you if the property is subject to road widening. Does WA not show the same thing?
