please dont think newer build means a good house, as has been previously mentioned almost all houses here (especially rentals) are just shite.
they look nice but there are massive performance issues.
new houses need to be 6* standard.
however this is achieved at the design stage.
there is no testing of the built house, independent or otherwise.
so from a good design, a company and builders can pretty much build what they like and call it (and charge for) 6*.
therefore a cheap house, built from the start to be a rental will be a rather steaming dog egg rolled in glitter.
a house for an owner will be better, but with an industry completely used to and geared to slum type construction even their best is subpar by even uk standards.
best to seal up some window architraves with plastic and live in a small part of the house during winter.
we did this in point cook and stayed warm, and are doing the same here in east melbourne.
you can also eventually build a real house, but its expensive!
