AI summary

Planning a new build requires a construction loan, which typically needs a 10% deposit. Unlike standard mortgages, funds are paid to your builder in stages as work progresses. During the build, you may have interest-only payment options.

To apply, you'll need a land agreement, a builder's contract, consents, and a valuation. You can choose a simple Turn key contract or a more flexible Build-only agreement. It's wise to budget for cost overruns and seek professional advice.
