G'day guys

I am looking for a 3 or 4 bedroom brand new property suitable to my requirement in Girraween and surrounding suburbs from last one year. I have seen almost all the newly built properties for sale in these areas in recent past through all major real estates including Laing & Simmons, Raywhite, Ljhooker, R&W, Starr Partners, Carrols etc and they all are offering me bathla properties.
After lot of research work I have concluded that approx. 80% brand new properties in these areas are being constructed by Bathla and rest 20% by individual builders who are not selling off the plan (stamp duty can’t be saved) and asking for approx $30K more than Bathla for similar configuration & finish properties. Also, there is no information available over internet about these small builders.
Few of my friends also have bought properties from Bathla and they don’t have any major concern except some minor repair issues. After going through the information available on this forum, I am in dilemma. I can save almost $45K by buying from them.The property is at convenient location. I have seen one property recently finished by Bathla and found that the building structure is better (First floor concrete) than other builders.
Can somebody help me to decide?
