The YOLO "hollywood movie"/NYT best seller answer, however, is to drop everything you're doing, go to Madagascar, spend some time trying and failing (with hijinx!) to grow the crop yourself. Your neighbors at first are distant and doubtful, but slowly you gain their respect. 15 years from today, tsingy brand coffee is a household name.
1) Do I enjoy the coffee business? Would I have bought that plantation if the opportunity had arisen? If the answer is no, selling is most likely the right answer.
2) That being said, it's not like the plantation is a hot potato that needs to be sold right away. OP has some time to check it out, learn about the business and decide if this is something worth trying for a few years. How long to try for? What's the opportunity cost? They would decide to invest a limited amount of time (e.g. one year of work) and then reevaluate at the end. I would timebox this decision process too. Perhaps learn all you can in a month and decide if you want to give it a shot? Part of this process should involve getting in touch with people in the industry and seeing if you like interacting with them. In the end, most of your job will be about interacting with the different types of players in your industry.
I'll try at least until the first harvest is sold or whatever happens. It cost me around 3000 euros a year to run for now. So YOLO
Best of luck!
the money made from letting a Netflix crew follow you around would probably help through bad seasons
