Hi, can anyone advise if online build calculators are accurate and up to date such as the bmt quantity surveyors. I want to check cost of building single storey in Sydney objectively. Have three builders quotes they varying wildly for 280sqm 4 bed 3 living 2 bath. 660k, 750k, 800k. Mid inclusions flat land.
The large difference makes me suspect price gouging or taking advantage of uninformed customer but i don't want someone who is too cheap and cut corners. How do you work out if the quote is reliable?
