https://www.smh.com.au/national/nsw...apartments-under-reforms-20200121-p53t7t.html Imagine if a US company that has never visited your high rise building, put a “Do Not Buy” profile on the 200 units in your complex where you own your PPOR. And it had state government blessing. All your local agents would know! No one would even look at the properties for sale. The 200 owners would more than likely become bankrupt overnight. It would be based on “opinion” rather than certified fact. It would lead to extraordinary greed and profiteering by schisms within the body corporate determined to buy the building for cents in the dollar, for redevelopment purposes. There would be factions hiding faults to boost the property values. There would be court cases against the value of such ratings. We already had a system. It was called builders licensing. If a building fails, take away the builders licence and sue the builder. BUT IN NSW there is no builders warranty required for buildings 4 storeys and over, because that would hurt the main funders of politicians, councils and corrupt bodies everywhere, so instead they make up a BS body that would bankrupt the owners of the units.
