This generally works with lower purchase prices.
Only a handful lenders do this and there is no hard and fast rule. ME Bank, ANZ, Westpac and St George are all lenders that "may" do this depending on the location, price, etc of the property.
side note - if it doesn't have a bathroom or kitchen then it will be deemed unliveable and you will have issues with finance.
Depending on a few things you may be limited in terms of lender selection and LVR.
You should definitely use this as a tool to negotiate with the agent.
