From what I’ve read and seen, development isn’t one skill, it’s coordination between design, finance, permits, and construction, so one person usually can’t cover everything well. I actually came across this breakdown and it explains it simply https://www.fields-builds.com/blog/building-a-successful-property-development-project the idea is that strong planning + coordination + risk control drive success, and that usually comes from having the right people involved, that said, for a small project, you can handle a lot yourself but more like a coordinator than a one-person expert, even experienced developers still rely on architects, engineers, or consultants for key parts. It’s less about doing everything alone, and more about knowing who to bring in and when.
