Actual build time was 6 months, it took them 6 months to begin building after initial deposit. Speaking to other people that seems about the norm if you are using a volume builder
Not really sure about prices for a 200sqm house sorry. If it helps our place was 180K before upgrades

We used Metricon for our PPOR took about a year from initial deposit to settlement for a single story approx 350sqm house
We used Metricon to build our PPOR and they have a site you can log onto that shows your progress and completion dates for specific tasks for example flooring, cabinets etc
The website seemed to get updated as things happened so I guess it was what you could call a daily update
