Subdivision and selling off the plan Melbourne

Hi guys,

i've got a planning permit for three 2 bed town houses in Fairfield Melbourne and now have everything to go to building contract stage.  It hasn't happened yet but I'm a little concerned that the bank valuation "as complete" is based on one lot as it is not yet subdivided and as such the LVR will be unworkable.  I've had a plan of subdivision completed and lodged but have been told the final subdivision cannot be completed until the buildings are in place as the final location of shared walls will be reassessed once built.  The bank won't value it as three separate titles until subdivision is complete.

I'm hoping someone may have some advice to get over, around or through this hurdle.  Alternatively, is there a way to sell one unit off the plan on the basis of the plan of subdivision to assist with the build cost of the development?

Any advice would be appreciated.  

Cheers

Ren
