The easiest way is to use our handy mortgage calculators to work out a budget, your borrowing power and likely home loan repayments. Then you can compare what you can afford to pay, with the prices for group-build house and land packages with a floorplan you like and in the area you’re considering. If you already have a section, ask a few of the larger building companies for the typical cost to build the home you’d like on the land you have.
