This probably sounds a little like wholesaling or being a Realtor, and it is.If you don't want to spend $1,000's to build this out and take on the associated tasks, there are other, more cost effective, options.I'd recommend looking for potential deals via free (or low-cost sources) i.e. local meetups/networking, Courts (probate & lis pendens lists), Realtors, Wholesalers, properties for sale online (especially those with 90+ days on market), etc.All the best!
