Chicken...
75 feet for a well is VERY shallow for a well. Ours is deep bore and is about 300 feet. Our old house had an old concrete well and even it was over 120 feet deep ( you know the type - about 3 feet around, the type a child can fall into?) - it was the 2nd well drilled on the property because the first one went dry. It too was shallow (around 75 feet). Even the first one went dry twice at 120 feet and the fire dept had to fill it up for us. we couldnt drink the water at all and had to use Chlorox to kill all the nasties that got mixed up from the water going in. Our neighbors also went dry. Remember you arent the only one on the water table if you're on a well.
If the well only goes 75 feet - then there is an issue with the water table and there is no way that well will support you or your livestock without going dry (and fast). Water tables (I know you're in FL so its a lower water table than in VA) but in general, your well should be alot deeper. Is it a deep bored well (like a 6 inch little white tube looking thing?) has it been inspected for fecal and other little buggies in the water? Get your OWN private well inspection for water - never trust the other guy (sorry... been burned by having a "Friend" of the people who owned the property inspect the well - and we all got sick on our first endeavor into house owning
years ago). Farmer John down the road had cows..... run off into the ground.. ran into the well water.. fecal not to mention other nasties. Needless to say we sold the house.
The land - did it perk and if so, for what alloted house amount (i.e, square footage/bedrooms) and does that include the barn/stables since you will more than likely have electricity to them and more than likely, plumbing. How about septic? If it has a well, it more than likely has septic. When was the last time the septic tank was cleaned out? (thats expensive and nasty to do). When was it put in (both well and septic) does it have a drainage field and where it that located? You cannot build on a drainage field (even a barn/stable) (at least here you cannot). If something happens with the lines, they have to be repaired (torn up) - makes moving a barn pretty near impossible.
As someone said - get soil samples and test them. If this land is on the cheap and all other land surrounding it is pretty expensive - then there's a reason for it. Either it didnt perk or the land isnt good for farming (soil). If its all clay, you're going to have issues with getting things to grow. Acidity and Ph play major roles in crops (I have issues here as our soil is heavy red clay
).
Whatever you decide to do - make sure all your bases are covered. Again, take someone that knows farming with you if you can - that knows crops and what you want to do with your land. It will make all the difference in the world, trust me.
Keep us posted hun! You're doing great but just keep doing your homework. That well really worries me to no end.....
