@Christopher Sparacino There is a lot of great information/experience being shared here. Personally, after 4 yrs. attempting to wholesale SF, my first deal was vacant land. YouTube University (as the young ppl call it these days) can give you a great foundation for learning how to flip/wholesale land. Some ppl/resources include: BP's YT channel (of course), Joe McCall, Jack Bosch - who spoke at a local CFRI meeting, and Flipping Mastery TV (showcases flipping/wholesaling related topics in general).
When I became interested in vacant land, I viewed flipping and wholesaling as two different processes with similarities. Flipping vacant land involves your purchase of the property with your own personal funds or transactional funds/lending (i.e.: double close), or you have been the original property owner for some time. Wholesaling vacant lots can be done as well since you would be assigning your contract on the property; however, be aware of state laws, the NAR and state Association regulations, and how the investor community of your niche regards real estate wholesaling.
Other things to consider are having an understanding of the documents needed to complete a transaction and having a solid list of end buyers/developers - research and compile lists for both! Having worked in real estate litigation as a legal assist/paralegal for over 8 yrs., try to find and work with investor experienced and friendly attorneys to either provide the paperwork or review your paperwork. Regarding buyers/developers, its best to connect with them and learn their buying criteria and due diligence period before getting under contract for a property. Depending on the conditions of the land and buyers'/developers' criteria, some perform their own due diligence and others may require you to complete the due diligence (and other prerequisites).
Lastly, as @Greg C. mentioned, do consider expanding to 3 - 5 county areas within your market of choice for vacant land flipping/wholesaling.
I hope you find the above information helpful and best wishes on your journey!
