OK, I might be able to help. That particular property is about 15 miles away from me. What do you need to know?
Soil
Quarzipsamment entisol, aka sugar sand. Extremely poor for growing. Commercial crops in this area are
hay and pine
trees. Drains extremely fast. 3 days after 12 inches of rain, I was watering my vegetables. Silt, clay, organic matter <2%.
Weather
Beautiful. It was 82 today.
Average rainfall is 54". This has been skewed the last few years. You can grow plenty of stuff in the winter, but the winter is dry.
Summer will be 95 every day with high humidity.
We get into the 20s at night for a couple of weeks a year. Winter days usually get above 60.
Hurricanes are usually blown out by the time they get this far inland, but we've had some strong winds and plenty of rains from them.
Critters
lots of mosquitos, especially at dawn and dusk. A snake here and there, moccasins are trouble. Potential for alligators around lakes and
water. Fire
ants, but you'll figure them out. Fox,
deer, turkey, boar, maybe a rare bear or bobcat.
Towns
Jasper is a small town, hardware store, small grocery store, a restaurant with a really awful breakfast buffet, hardware store, everything you must have but not much else
Live Oak is 15 minutes, bigger, Lowes, Walmart
Lake
City, 30 minute drive, big
enough to have most things a city offers
Gainesville, an hour to 1.5 hours, you are back in civilization
Jax, 2 hours, metropolis
Taxes
Hamilton County is small, property taxes are low. With a 25k homestead exemption, there would be practically no taxes on that property if you lived there.
Florida has no state income tax
sales tax is 7%
Jobs
few and far between, but the cost of living is low.
At $9500 they are giving the property away. Real estate is kinda slow right now (brother's wife is a realtor). This property is a couple miles from the Suwannee River, you may be in a flood zone-this can be a serious flaw. I don't see power lines to the mobile home. If well and septic are hooked up and it has power, the price is going to be hard to beat. I can't say the old trailer will be acceptable for your living standards. Sitting without ventilation is not good down here with the heat and humidity. I think what you have here is someone dumping the property, and while they are at it, they parked the old trailer to make it someone else's problem.
