4 acres per head of cattle of good pasture to raise from birth to slaughter is what we figure on. My sister and some of my other family run cattle. Grandparents ran a good sized cattle operation that we worked off of horseback. You can run goats on a heck of a lot less land and the land doesn't need to be all pasture since they browse instead of graze.
In Florida, you shouldn't need much hay I wouldn't think.
Hogs raise pretty fast, but you need good fencing and to ring their snouts.
The problem with a lot of land and cattle is that they are out from the homestead and are fair game to rustlers if you don't have a watch on them 24/7. Goats are easier to bring in each evening and you don't need as big of a shelter for them.
I don't want to fool with cattle on our place, but we go help work them at the families and yeah, still mostly from the saddle.
You have to decide how much you want fenced and how you are going to fence it. Is the ground good for growing? If it is, what is going to do well there? Plant three times as much as you think you will need, invariably you will lose some to critters, weather, and pests.
When you look at a place, make sure whatever water that is there hasn't been contaminated by ag runoff or in a cow pasture. If it's a pond, fence it off from your animals, you don't want them in your water supply.
With a big garden or gardens, do you have the means to work the soil each year? Tillers will only work for as long as there is fuel to run them, the same with tractors. We farm here, big gardens, hay, livestock, but we don't use tractors. Everything is literally horsepower.
What kind of weather does the property get, what extremes will you need to plan for? In the right climates, you can live in large tents or yurts year round. If it's a warmer climate you'll just need something to break the wind and rain for the animals, nothing elaborate.
With chickens, you can let them free range, but you'll lose a lot of them. Fenced runs work well to keep predators out.
