I finally got myself a property in northern suburb of Melbourne. Nice block for the area 550m2. The house sitting on it is pretty old, at a minimum re-stumping and a new roof is needed. I want to build units but the costs associated with it scares me off a little. So I think I have settled on rebuilding and my job is not going to allow me to self-manage the project. So after looking around I started to bump into sites such as Metricon, Burbank, Somonds ect. Their prices are in my range ~$150-175 and the houses look good (from the internet). So I guess my question is are these type of places reputable? Is it value for money considering you sit back? How high are penalty fees for deviating from their plan, i.e put my own oven, or move the bathroom ect.? I'm looking to make this place my primary residence, dog and all.
