Just as an update, the current rate for the 90% lo doc is 8.35%.
A no-doc construction loan may no be required for your project, depending on the nature of the project. There are loans available at 75% of end value of the project with reasonable rates. Interest can be capitalised to the 75% limit so you don't need to make repayments during the development.
Whilst not a no-doc loan, they don't look as the serviceability as much as they look at the feasibility of the project.
At the end, you either sell or refinance the properties to a more appropriate loan. Fees on these loans are in the order of 1% to 3% (set up fees, ongoing and exit). Specific rates are hard to quote without understanding the project.
