Once you get the hang of it at the ground and upper level, it's easier to assess what properties for sale are actually worth it. Not to mention you will also have the knowledge of improving sites, which may well have been undervalued/undermonetized by their previous owner. Outsource all mundane tasks and keep scaling up.
