Hi everybody I would like to develop in the future just jumped on pc to start my research im thinking of starting with a duplex / townhouse for first project . I'm aware of the council research on area in regards to zoning etc. What I'm not sure of are the numbers I should be costing in from purchase , development to sale to make a profit sure there will be holding costs as well . I ask this so I know what to purchase a property for knowing that I plan to develop . Any help would be great ..
