Hi all, Double posted in the Commercial Property section. Short story - my parents own a 3,300 sqm block zoned B4 Mixed Use. We've already agreed that the long term best use for our block is for a development rather than selling as a going concern. There are adjoining houses zoned R2 Low Density Residential. One of the owners has just approached us to buy his block, which would be a good addition to our own and take the parcel to 3,900 sqm with highway frontage and rear lane access. We're trying to work out what sort of offer we should make him. Does anyone know how easy/expensive it is to get R2 rezoned to B4 if it is already adjoining a B4 block (Lake Macquarie Council area)? If the parcel grows from it's current 3300 sqm to 3900 sqm would that significantly increase value? We're probably not going to be able to do a development of this size ourselves so would be selling it as a development site. A bit worried that as the block size, and scale of development gets too large it actually limits your potential buyers and you lose some negotiating power.
