Small scale hobby, yes. Income, hell no! I'm a niche farmer and can tell you mother nature is a cruel mistress. I do this only to get out in the fresh air and do something constructive rather than wasting away in front of the boob tube.
What's the going asking price for raw, undeveloped land around Pine Island, small acreage aka 5 acres?
Having said that they aren't making any more land and it will appreciate. I bought farm acreage in 2005 for $4,950/a.c.. Had electricity, land line, well with great water, etc. Not that I ever got even close, but I was authorized by the underground water district to use up to 3 million gals. of water a year for my irrigation op. Today you can't touch undeveloped land for less than $20,000/acre around me and that's for the larger tracts too. What we don't have is dishonest eye pokers, govt. fees, permits, regulations and all the other extraneous costs that makes California (and I guess Florida) so expensive.
Infrastructure considerations - ROW, road/drive, well, septic tank, deer fence, pump hardware, labor.......... A professionally installed high tensile steel deer fence with 2 gates back in 2004 cost us $3.00/ft. Today it's running $10/ft.
Good luck!
