The only RZ2 block in this batch, and the zone changes the question. On RZ1 the argument is whether a second dwelling pays for itself. On RZ2 it is where on the curve to stop.
911 m², nearly twenty-six metres of frontage, and 455 m² of gross floor area at a plot ratio of 0.5. The charge is $77,000 payable at two dwellings and $97,750 at three — so the second dwelling costs $77,000 and the third costs $20,750. That is the shape of the schedule, and it is why pricing the whole curve matters more than pricing whichever scheme a builder suggested first.
Unimproved value is $877,000, up from $856,000.
Whether three is right stops being a statutory question at that point and becomes a build and sales one: three dwellings inside 455 m² of floor area is three small ones. The charge stops being the binding constraint somewhere around here, and that transition is the thing worth understanding before you model anything.

The licence, the charge and the planning pathway are all downstream of one question: is the block worth developing at all? Put an ACT address in and get the zone, the unimproved value, the Lease Variation Charge at two, three or four dwellings, and a verdict on the asking price.
