Item	Information
* Project home package – progress payments	If you have a loan to finance your project home build, you must continue to make payments throughout the build process. Speak with your bank or lender to understand your payment schedule.
* Principal certifier	You must appoint a principal certifier if your development needs approval, such as a development application (DA) or complying development certificate (CDC). Check your certification contract to see what is and is not included. All certifier fees are paid upfront.
Mortgage payments	If you have a loan to finance your project home build, you must start to make mortgage repayments once the first progress payment is made and you begin to draw down on your loan. Speak with your bank or lender to understand your payment schedule.
Third-party building inspector	You may wish to hire an independent building inspector to check your home is being built to construction codes and standards. Speak to your third-party inspector to understand fees and inspection stages.
