@Eric Dandridge I have experience as a wholesaler targeting land for specific developers in our area. What worked for me in my market of Charleston, SC was picking an area with a high number of vacancies as well as dilapidated properties and empty lots. Once I found a area that fit this criteria I marketed to the list as a whole, then got more specific and called the owners directly that had tax delinquent issues and offered to pay the taxes and give them a small fee at closing much like @Jon Deavers suggested. This consistently gave the developer a large number of properties to work with so they could buy in bulk and add to their portfolio.
I would then find a company in your specific area that has a history of developing in your city, you can easily access this info on the tax accessor site to see who is buying the most property in a general area.I would then find their director of investments or any decision makers within their acquisitions team.With this strategy I have successfully enabled a developer in my area to buy over 40 parcels and he is now the largest land owner in that specific the neighborhood in only one year. If you have any questions feel free to send me a pm! GOOD LUCK!
