Hi. I have two properties next to each other in Gawler. Both a third of an acre. Each property has a house at the front. We want to subdivide and sell front of land, probably to a developer and keep one driveway and back land for us. Both houses are rentals. There would be enough room for 4 townhouses across the front. I have begun researching. What are the foundation research no 1's to start with? Thank you all.
