So I know all sites/projects are different / it is all in the Feaso / what scenario stacks up best for one site might not be best for another, BUT, in general with all other things being equal, which is more likely to yield the higher return on investment: a duplex or triplex development project? Or is the answer that it depends on the project and neither is inherently more profitable? It appears to me that doing more volume has obvious cost savings in terms of: *Reduced stamp duty (pay SD once to yield 3 properties) - noting that some of this absorbed by a larger triplex site will cost more and therefore be higher stamp duty than a duplex site in the same area; *Potential cost savings from having builder construct more dwellings on the one site. Is this the case? *Reduced personal time/effort. Slight increase in time/effort required to research, do feaso, purchase, plan, choose builder, develop, etc for a 30% increase in properties held at end of project = less time per property. *Potentially less competition for triplex sites = better value? More mum n dad investors are willing and able to undertake duplex developments therefore might there be more demand for these sites and therefore higher prices? FYI is an open question, however in my case I am looking at it in terms of a 'develop to hold/rent' scenario.
